O (Crockett) My name is William G. Crockett. I am the 27

) 28 Manager of Technical and Support Services for PG&E at 29 DCPP. I am responsible for Engineering Support, including O

O 1 System Engineering, Plant Engineering, Training, Security, O 2 351 General Services. I oversee the development and 3 evaluation of the DCPP surveillance testing program. I am 4 tha primary site interface with the Design Engineering O 5 section of the Nuclear Engineering Services Department, l'

6 with PG&E's Computer Services Department, and with the )i 7 Nuclear Regulatory Services Department. I have 16 years O 8 of nuclear power experience in operations, maintenance, 9 and engineeriny, including 14 years at DCPP. I hold a 10 Senior Reactor Operators ("SRO") license (inactive) for O 11 both units at DCPP. A summary of my professional 12 qualifications and experience is provided in Exhibit 2.

13 (Vosburg) My name is David A. Vosburg. I am Director

O 14 of the Work Planning Section in the Maintenance Services l

15 Department at DCPP. I am responsible for maintenance 16 planning activities and for scheduling of maintenance, I

O 17 post-maintenance testing, and plant modification 18 activities during normal and outage conditions. I have 16 l

j 19 years experience in the nuclear power industry, including i

3 20 13 years at DCPP. In my 13 years at DCPP, I have worked 21 in the Operations, Engineering, and Maintenance l

22 Departments. I maintained an SRO license for DCPP from f

'O 23 1982 to 1992. A summary of my professional qualifications 24 and experience is provided in Exhibit 3.

25 (Ortore) My name is Steven R. Ortore. I am the O 26 Director of the Electrical Maintenance Section in the 27 Maintenance Srrvices Department at DCPP. I am responsible t

28 for maintenance of all electrical equipment at the plant.

O 2

O r 1 I was formerly the Director of Material Services at DCPP, f

2 which included responsibility for procurement. I have 19 g

3 years of experience in the nuclear industry, of which 9 4 years have been at DCPP. A summary of my professional 5 qualifications and experience is provided in Exhibit 4.

a, 6 Q2 What contention will the panel address?

i O

7 A2 (All) We will address the San Luis Obispo Mothers for 8 Peace ("MFP") Contention I: Maintenance and Surveillance.

c, 9 MFP in the contention alleges that PG&E lacks a p

10 sufficiently effective and comprehensive maintenance and ,

I l

11 surveillance program to jcstify the operating license 4 l

, 12 amendment here at issue. That amendment would extend the l DCPP Unit 1 and Unit 2 operating licenses to the full 13 14 40-year term that was assumed in the original plant i

g 15 design. A copy of PG&E's license amendment application is 16 provided as E?.hibit 5.

l l

l 17 Q3 What is the purpose of your testimony?

,O l

18 A3 (All) The purpose of our testimony is to provide a i 1

19 response to the above contention. This testinony will.

) i 20 demonstrate that PG&E has implemented a comprehensive i l

21 maintenance and surveillance program at DCPP.

, 22 Maintenance and surveillance activities at DCPP address 23 degradation of equipment, whether due to equipment aging 24 or service wear, that has been experienced to date or that a

,)

0-1 is expected over a 4G-year plant operating lifetime. This O 2 specifically includes any pre-operational equipment 3 degradation. Contrary to MFP's claims, PG&E has 4 implemented its maintenance and surveillance programs in 5 an effe tive, and often outstanding, manner. PG&E O

6 recognizes the importance of maintenance and surveillance 7 to efficient, reliable, and safe operation. PG&E has 8 devoted considerable attention to this area and will 9

9 continue to do so for the full 40 years of operation to be I 10 authorized by the proposed license amendment.

O 11 II. OVERVIEW g 12 Q4 What is the definition of " maintenance" as the term is 13 used in your testimony?

14 A4 (All) Maintenance as used in this testimony includes:

O 15 those activities which are performed to assure that 16 structures, systems and components ("SSCs") will continue O- 17 to operate as designed, as well as those activities 18 necessary to repair or replace SSCs that are degraded or 19 cannot perform the intended function. Maintenance is Cy 20 considered to be the aggregate of actions at DCPP that (1) 21 minimizes the degradation or failure of SSCs, and (2) 22 promptly restores the intended function of SSCs if they o 23 experience operability or functional problens.

I 4 o-_

O 1 QS What is the definition of " surveillance" as used in 2 your testimony?

O 3 A5 (All) Surveillance as used in this testimony is the 4 aggregate of periodic tests and/or inspections that verify 5 that SSCs continue to function in accordance with 6 predetermined specifications or are in a state of 7 readiness to perform their particular safety functions.

O 8 Surveillance activities can trigger maintenance activities 9 based upon the results of the particular tests or 10 inspections.

O 11 Q6 What is the scope of issues raised in the contention 12 and addressed by your testimony?

l O

13 A6 (All) MFP in Contention I alleges that the maintenance 14 and surveillance pr' grams at DCPP are not comprehensive O .

15 and effective. Our testimony will demonstrate that the i 16 overall maintenance and surveillance programs established ,

17 at DCPP are comprehensive and effective in assuring the 18 safe and reliable operation of DCPP. The programs meet 19 all established requirements and are effective in 20 identifying and rectifying potential and actual sources of O

21 equipment degradation. Moreover, as will be discussed in

( 22 detail later in this testimony, the individual isolated 23 items cited by MFP as bases for Contention I indicate O

24 that, contrary to MFP's claims, our maintenance and I

s O

D 1 surveillance programs are functioning well and as 2 intended, in a comprehensive and effective manner.

3 3 Q7 How do DCPP maintenance and surveillance programs 4 address " aging" of equipment 7 3

5 A7 (Giffin, Crockett) Equipment aging management is a l

6 concept that is integral to the overall philosophy of an 7 effective maintenance and surveillance program. PG&E 8 recognizes that SSCs can deteriorate as service life 9 increases due to " age-related degradation." " Age-related 3

10 degradation," as defined by the Electric Power Research l

11 Institute ("EPRI"), is the gradual deterioration in the 3 12 physical characteristics of an SSC due to aging mechanisms 13 and which occurs with time or use and could impair the 14 ability of the SSC to perform any of its design functions.

15 An " aging mechanism" is a process that gradually changes 3

16 the physical characteristics of an SSC with time or use.

17 Some examples of aging mechanisms are fatigue, erosion, 18 corrosion, radiation embrittlement, thermal embrittle'v:nt, 3

19 and service wear.

I 20 In the case of certain critical components which are l

21 subject to complex aging mechanisms (e.g., the reactor 3

22 vessel and steam generators), or components which may have 23 limited life, special programs have been developed and 7

24 implemented at DCPP to manage the aging process. These 25 programs are discussed in more detail later in this 26 testimony. For those components where special programs 6

3 L __

D 1 1 have not been developed, normal maintenance and 2 surveillance activities provide for and facilitate the 3 management of aging mechanisms. DCPP's maintenance and 4 surveillance programs are designed to (1) minimize l

L 5 deterioration through routine maintenance, (2) predict the J

l 6 rate of deterioration, and (3) detect the deterioration of i

7 equipment. Specific maintenance tasks respond to '

8 unacceptable SSC conditions either by equipment repair or j O

r I

1 l 9 replacement.  !

1 10 DCPP, like other nuclear power plants, was designed to I

11 operate for at least 40 years. In order to assure safe I J

l 12 operation, a defense-in-depth philosophy was incorporated 13 into the plant design, the~ plant operating programs, and 14 the maintenance and surveillance programs. Specifically, U i 15 design features have been incorporated to provide the I 16 ability to test, inspect, and perform preventive 17 maintenance on SSCs. Furthermore, the plant was designed 18 with redundant trains of safety-related equipment to be l 19 able to accommodate equipment failures that are random in 20 time or location. The operators are also trained to J

21 recognize and respond to equipment problems, and the 22 naintenance programs are established to assure that 23 equipment problems, which are detected through routine

,J l 24 surveillance and operating experience, are corrected.

25 As the NRC has recognized in issuing numerous 40-year 26 operating licenses, and in issuing many license amendments 27 similar to that at issue here, effective and comprehensive 28 maintenance and surveillance programs assure that O

O 1 detectable aging effects are addressed prior to their

() 2 becoming a safety issue.

3 Q8 What is the relationship between the specific, O 4 individual events alleged by MFP in their bases advanced 5 in support of Contention I, and the effectiveness and 6 comprehensiveness of DCPP's maintenance and surveillance O 7 program?

8 AB (Giffin) Our testimony will show that the specific o 9 examples MFP uses to support its contention that the 10 maintenance and surveillance programs at DCPP are not 11 effective or comprehensive do not, in fact, indicate a 0 12 breakdown in the overall programs. None of the examples 13 resulted in a situation with safety significance. Some 14 are not maintenance-related and those that are do not o 15 prove an inadequacy in program scope or its overall 16 implementation. Some cf the examples are simply 17 situations in which the maintenance and surveillance O la program has worked precisely as intended. In all cases, 19 where specific equipment problems were identified or j 20 performance weaknesses were observed, corrective actions O 21 have been taken. PGLE believes that the examples cited by 22 MFP illustrate a maintenance program that is working and 23 reflect a strong commitment to continuous improvement.

O 24 MFP speculates that weaknesses in maintenance follow-25 from the DCPP rate case settlement and the financial 26 structure for DCPP rates. However, none of the examples O 8

D 1 cited by MFP in the basis for Contention I supports this D 2 speculation. None of the examples involved delay in 3 necessary corrective actions or repairs. In fact, 4 necessary repairs were made while the plant was operating.

}

) 5 Contrary to MFP, there are times when either unit of DCPP 6 is curtailed at PG&E's discretion in order for prudent l

7 repairs or inspections to be performed. These 8 curtailments evidence PG&E's commitment to safe operation

() 1 I

9 as the highest goal for DCPP.

O 10 Q9 Could you give us a quantitative measure of the i i 11 magnitude of the maintenance and surveillance program at {

t 12 DCPP?

O 13 A9 (Giffin, Vosburg) There are approximately 20,000 work 14 activities which require a work order performed each year

() 15 at DCPP. This includes 6,000 preventive and 7,000 l

l 16 corrective maintenance tasks. In addition, there are 17 approximately 10,000 surveillances performed each year, 1

C) 18 7,000 of which require a work order. Many of these work 19 activities consist of a large number of sequential steps 20 or elements. These are three year averages of the number

'O 21 of work orders performed. It is worth noting that tha 22 number of corrective maintenance tasks has decreased 23 steadily for the past three years. In 1990, there were 9 24 9,000; in 1992, 6,000; and we estimate fewer than 5,000 25 this year.

1 O.

1 In the context of these numbers, it must be recognized i

2 that the design of the plant; the checks and balances  !

O l 3 inherent in the maintenance and surveillance programs; 4 state of the art tools, test equipment, and facilities; 5 and the training and qualifications of the maintenance O

6 personnel all provide assurance that there will be a .

7 minimal number of errors made and that when errors are 8 made or equipment degrades, there will be no safety O

9 significance.

10 III. DESCRIPTION OF DCPP MAINTENANCE AND SURVEILLANCE PROGRAMS O

11 Q10 What programs at DCPP are included within the umbrella 12 of " maintenance and surveillance" programs? '

'O 13 A10 (Giffin, Crockett) At DCPP, PG&E has established 14 several programs or activities that addressing topic of

-O '

15 maintenance and surveillance of safety-related equipment.

16 These include:

17

  • Technical Specification required surveillances;
O 18
  • Numerous equipment surveillances not required by the 19 operating license; 20
  • Inservice Inspection ("ISI")/ Inservice Testing ("IST") .

'O 21 Programs; ,

22

  • The Environmental Qualification ("EQ") Program; and 23
  • The Maintenance Program.

.O 24 These activities and programs collectively assure that any 25 significant degradation of plant equipment will be 10

'O

O 1 promptly identified and addressed throughout the proposed O 2 40-year operating license terms.

3 Technical Specification Surveillances

]

O 4 Q11 Please describe the role of Technical Specification 5 surveillances?

\

I O 6 All (Crockett, ciffin) DCPP Technical Specifications are 7 part of the plant NRC operating license and include 8 numerous requirements for testing and/or assessment of O 9 safety-related SSCs. PG&E has adopted a surveillance and lo testing program in accordance with the industry standard 11 ANSI N18.7-1976/ANS 3.2, " Administrative Controls and O 12 Quality Assurance for the operation Phase of Nuclear Power 13 Plants." In accordance with PG&E procedure NPAP-C3, 14 " Conduct of Plant and Equipment Tests," the DCPP o 15 surveillance and testing program administratively controls 16 the surveillance testing required by the Technical 17 Specifications. A computerized master schedule is used to l

'O 18 schedule and track the status of Technical Specification 19 surveillance tests and to ensure that these tests are 20 performed at the required intervals.

O. 21 over 10,000 Technical Specification-required 22 surveillance tests are performed at DCPP each year. The 23 actual number of SSCs tested is much higher because many O 24 surveillances actually test multiple components. If the 25 results of a surveillance test are not within specific 26 operability limits, the SSC is declared inoperable and the 0 11

O 1

'l Technical Specifications provisions are invoked. In these 2 cases, PG&E initiates problem investigations and necessary O

3 maintenance activities to restore the SSC to its design 4 condition in a timely fashion. Technical Specification 5 surveillance testing provides assurance that 6 safety-related equipment failures or substandard equipment 7 perfo"mance will not remain undetected and that the l-8 requirec reliability and state of readiness of SSCs to l' O

9 functicn in accordance with predetermined specifications 10 is maintained for the life of the plant.

O 11 Other Surveillances 12 Q12 Are there routine surv'eillances of SSCs at DCPP other 13 than Technical Specification surveillances?

f l

14 A12 (Crockett, Giffin) Yes. In a broad sense, there are 15 many plant activities in addition to Technical 16 Specification-required surveillance test procedures which 17 result in surveillance information about equipment 18 condition and performance. Examples of these activities 19 are:

20

  • Routine operator plant equipment inspections as 21 required by Administrative Procedure DLAP O

22 OPl.DC3, " Auxiliary Operator Routine Plant i

23 Equipment Inspections;"

24 e Predictive maintenance program testing (e.g.,

25 vibration monitoring, oil analysis, and thermography) l 12 O

. 1 0

1 as specified in Administrative Procedure C-751, 2 " Predictive Maintenance Program;"

O 3

  • Preventive maintenance program inspections (e.g.,

4 routine inspections of check valves) as required by 5 Administrative Procedures C-750, " Maintenance 6 Department Preventive Maintenance Program," and C-450, 7 " Instrument and Controls Preventive Maintenance;"

8

  • Procedure functional checks (e.g., turbine trip q 9 testing during startup);

10

  • Performance tests of important equipment not 11 controlled by the Technical Specifications (e.g.,

g 12 equipment controlled by Equipment Control Guidelines),

13 as described in Administrative Procedure DLAP  ;

14 OPl.DC16, " Control of Plant Equipment Not Reg.uired by 15 the Technical Specifications;"

16

  • Inspections performed as part of the erosion / corrosion l 17 m nitoring program required by Administrative 0

18 Procedure D-300, " Monitoring of Erosion / Corrosion .

19 Induced Pipe Wall Thinning;"

g 20

  • Testing performed after maintenance to verify that 21 equipment performance has been restored to the 22 required level as specified in Administrative 23 Procedure C-6sa, " Post Maintenance Testing;" and O

24

  • System engineer quarterly equipment walkdowns in 25 accordance with Administrative Procedure TS5.IDI, 26 " System Engineering Program."

O 27 All of these different tects and inspections provide I

28 detailed, specific, on-going information about the current  ;

)

1 condition of plant SSCs. These tests also provide 2 thousands of data points on the performance of plant 3 equipment, which are included and reviewed in the ,

l 4 preventive and predictive maintenance programs' Based on .

5 this information, maintenance is scheduled and performed 6 in a manner that maintains equipment performance at the

} 7 required level for the life of the plant.

[

l' 8 ISI/IST Programs 3 Q13 You listed in A10 above the ISI/IST Program. Please 10 briefly describe this category of surveillance testing.

11 A13 (Crockett) The ISI and IST Programs were initiated in 12 1985 for Unit 1 and in 1986 for Unit 2, corresponding to

) 13 the start of commercial operation of each unit.

] 8 The EQ Program for DCPP complies with the requirements 9 of 10 CFR 50.49. As applied to DCPP, 10 CFR 50.49 10 requires that electric equipment important to safety and 11 located in a harsh post-accident environment be

])

12 environmentally qualified, at a minimum, in accordance 13 with IEEE 323-1971 and the Category II positions in 14 NUREG-0588, dated December 1979. In accordance with 10 15 CFR 50.49(1), replacement equipment (for equipment that is 16 required to be environmentally qualified) is required to 17 be qualified in accordance with IEEE Standard 323-1974 and

{}

18 the Category I positions in NUREG-0588, unless there are 19 sound reasons to the contrary. The DCPP EQ program was 20 evaluated and found by the NRC to be in conformance with 21 applicable requirements in 1981 and 1985.

22 As described in detail later in this testimony, D- 23 maintenance of EQ equipment is a formal program at DCPP.

24 The master list of equipment required to be

-25 environmentally qualified is maintained as a controlled J- 26 engineering drawing and is revised as plant design changes 27 are implemented. Surveillance activities are performed-to 28 detect adverse trends in equipment performance or the J- 17 j

-O i 1 normal operating environment. Maintenance procedures

() 2 assure that the qualified configuration of equipment is 3 restored after maintenance and that appropriate 4 maintenance activities are conducted to preserve the O 5 qualified status. Equipment that is not qualified for the 6 entire 40-year operating license term is refurbished or 7 replaced prior to exceeding its " qualified life."

O 8 Maintenance Procram 9 Q15 The major element relevant to MFP's contention under Q 10 the maintenance and surveillance umbrella referenced in 11 A10 is the Maintenance Program. Please describe this 12 program generally.

O 13 A15 (Giffin) As noted above, maintenance is the integrated 14 means of maintaining the plant material condition 0 15 throughout the plant's operating life by managing the 16 effects of degradation and service wear on SSCs. The DCPP 17 Maintenance Program was developed with the basic O 18 philosophy that it is necessary to have the requisite 19 administrative and technical controls to ensure that 20 maintenance is performed in a timely, controlled, and safe O 21 manner, consistent with applicable requirements, the 22 license, and quality control criteria.

23 The DCPP Maintenance Program has been implemented O 24 through procedures which incorporate relevant information 25 from the Technical Specifications, design basis criteria, 26 industry standards, equipment vendor and manufacturer i

3 They provide the means to monitor, inspect, maintain, and 4 test plant SSCs in a programmatic manner. The program 5 includes maintenance tasks on both safety and g

6 non-safety-related SSCs.

7 As will be described further in this testimony, 8 maintenance tasks are categorized as either preventive or

)

9 corrective maintenance. Preventive and corrective 10 maintenance tasks were initially identified and initiated 11 during the plant construction phase. Maintenance g

12 activities have been conducted throughout the construction.

13 phase, the system turnover to plant staff, the period from g 14 operational testing through the start of commercial 15 operation, and during commercial operation. This helps to 16 assure that SSCs were not adversely affected during the 17 period of plant construction. Additionally, Westinghouse O

18 was present onsite during the construction phase and has 19 provided preventive maintenance information and guidelines 20 for the Nuclear Steam Supply System ("NSSS") equipment it O

21 supplied. The Westinghouse guidelines also include 22 recommended chemistry controls and system layup 23 conditions.

O 24 In addition to procedural guidance on specific 25 maintenance activities, maintenance procedures also 26 provide for scheduling, implementing, and documenting O.

27 activities covered by the Maintenance Program. PG&E

\

28 installed a computer-based Plant Information Management 19

'O l

O 1 System ("PIMS") in 1985 to assist plant maintenance and 2 engineering personnel in these activities. PG&E also O

3 committed additional resources to develop state-of-the-art 4 machine shops, maintenance training facilities, spare 5 parts invent ries, and management systems. Staff O

6 resources and personnel training are provided to fully 7 implement and use these support resources. All of these 8 program elements are described in more detail later in O

9 this testimony.

1 Q16 Y u menti ned PIMS. What is PIMS?

O 11 A16 (Crockett) PIMS is a computer-based system that 12 utilizes a mainframe computer system at DCPP. PIMS runs O

13 on a local area network and is available 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> a day to 14 over 3,000 users. It functions to improve information 15 fl w, w rk planning, and productivity. It is regarded as

'O 16 one of the most comprehensive information systems in the 17 nuclear industry.

f I

8 and surveillance programs?

g 9 A17 (Giffin) The requirements for the implementation of 10 maintenance and surveillance programs are found or <

11 referenced in several places. The DCPP Technical g 12 Specifications provide surveillance requirements for {

13 safety-related equipment and specify the requirements for 14 the ISI/IST program as described above. The Code of 3 15 Federal Regulations, 10 CFR Part 50, also provides certain 16 specific requirements, such as the EQ requirements. These 17 provisions, however, contain no explicit requirements for 3 18 a maintenance program. PGLE has committed in the DCPP 19 Final Safety Analysis Report Update ("FSAR") to follow the 20 standards of ANSI 18.7-1976/ANS-3.2, " Administrative g 21 Controls and Quality Assurance for the Operational Phase l 22 of Nuclear Power Plants," as endorsed and modified by the 23 NRC, in Regulatory Guide 1.33, " Quality Assurance Program 24 Requirements (Operation) .

0 >

12 and balance-of-plant (" BOP") equipment.

13 The NRC is implementing a new maintenance rule  ;

(10 CFR 50.65) which will become effective in 1996. Our

! 18 IV. ELEMENTS OF AN EFFECTIVE AND COMPREHENSIVE I

[,,

J 19 MAINTENANCE PROGRAM L

20 Q18 Focusing now on the DCPP Maintenance Program, is there L 21 any objective standard by which to judge the proper scope O

5 22 of such a program?

t 23 A18 (Giffin) Yes. Maintenance is a very complex and  ;

24 interrelated program which includes (1) the identification t

25 of an equipment problem or potential equipment problem, {

22  ;

3- i

6 1 (2) the planning of the work activity intended to prevent g 2 a problem from occurring or to return the equipment to its 3 design condition, (3) the preparation of a detailed 4 procedure or work order defining the steps necessary to

) 5 perform the work, (4) scheduling the work activity, 6 (5) obtaining the parts which are necessary to complete 7 the task, (6) assigning qualified personnel to actually

[) 8 perform the work, (7) performing the work, and (8) 9 performing necessary testing at the completion of the work 10 to ensure that the equipment is in operable condition.

[) 11 With this scope in mind, the nuclear industry and the NRC 12 have generally agreed that the Institute of Nuclear Power 13 Operations ("INPO") document 90-008, " Maintenance Programs 14 in the Nuclear Power Industry," (Revision 1, March 1990),

[)

15 identifies the requisite elements for a comprehensive 16 maintenance program. INPO 90-008 was recognized by the

[) 17 NRC in its Statement of Considerations for the Maintenance 18 Rule, and the NRC expressly found that detailed 19 recommendttions for the conduct of maintenance, such as

() 20 INPO 90-008, should be developed by the licensee, not the 21 NRC. (See 56 Federal Register 31,313, July 10, 1991.)

22 These elements are:

) 23

  • A well-staffed and qualified organization that is 24 provided with the tools and facilities necessary to 25 perform tasks effectively and efficiently; e 26
  • A proper nix of corrective and preventive maintenance 27 to provide assurance that equipment degradation is 28 identified and corrected prior to failure; i

g 23

  • Accurate procedures or work instructions for craftsmen 2 so that the work activities can be performed in a i

)-

3 quality manner; a

4

  • Maintenance planning and scheduling to assure that all 5 involved plant departments are aware of the activities
0 v

6 and interferences are minimized;  ;

, 7

  • Post-maintenance testing to verify that the 4 8 maintenance task was performed correctly and the 3 0 9 equipment is ready to be returned to service; 1 10
  • Availability of correct and qualified parts and 11 material to support the repair and return to service 12 of the component; ,

i 13

  • Control of measuring a'nd test equipment to ensure the 1 14 accurate performance of instrumentation and equipment O

, 15 used for calibrations, testing, and repairs; 16

  • A detailed root cause analysis program to understand  ;

17 the cause of equipment failures; and

0 1
18
  • A maintenance history program to provide historical i 19 data for maintenance planning and to support trending 20 analyses of equipment performance.

O 1 21 Similar but less-detailed elements are identified in J 22 ANSI 18.7-1976/ANS-3.2. The elements of INPO 90-008 have

O 23 been addressed in the DCPP Maintenance Program and are 24 explained in our Program Directive MA1 " Maintenance." The 25 Program Directive is included with this testimony as 1 1

26 Exhibit 6.

Q i

D 1 Maintenance Orcanization 2 Q19 The first element of a maintenance program is a well-3 3 staffed and qualified organization with necessary tools 4 and facilities. Let us break this element into three sub-5 topics and address each: the maintenance organization, 6 the training and qualifications of maintenance personnel, 7 and maintenance facilities. First, please describe the 8 maintenance organization for DCPP?

g 9 A19 (Giffin) The DCPP maintenance organization is clearly 10 identified and has been communicated to personnel so that g

11 responsibilities, lines of communication, performance 12 objectives, and mission are clearly understood. The DCPP 13 Maintenance Services Department organization chart is g

14 included as Exhibit 7 to this testimony.

15 About four years ago, the DCPP maintenance functions 16 were part of three different departments. A decision was

)

17 made to arrange the plant organization along functional 18 areas. Accordingly, the Maintenance Services Department 19 was established and the sections having maintenance

)

20 responsibilities were assigned to that department. The 21 Maintenance Services Department now consists of six 22 sections: Electrical Maintenance, Mechanical Maintenance, g

23 Instrumentation and Controls ("I&C"), Work Planning and  ;

24 Scheduling, Materials, and Outage Management. There are g 25 approximately 598 employees in the Maintenance Services 26 Department, 300 union employees, 298 professionals. This  ;

.O 3 Q20 Please describe each organization within the 4 Maintenance Services Department individually, with the

.O 5 section responsibilities and the staffing.

,O 6 A20 (Giffin) The Mechanical Maintenance Section is >

! 7 responsible for maintaining and servicing all mechanical l 8 components at DCPP. This includes the supervision and

! 9 programmatic controls needed to ensure that all components 10 10 are monitored and maintained in reliable working 11 condition. Engineering support within the section 12 provides procedural guidance, troubleshooting, and 13 techrical direction. The Mechanical Maintenance Section 14 consists of 157 employees.

15 The I&C Section is responsible for the maintenance and 16 periodic testing of all plant instrumentation. Duties 17 include the supervision and administration of the 18 preventive and corrective maintenance programs for that 19 equipment, and the implementation of the Technical

(1 2 captures items that worked well or things that need to be 3 improved during outages. During non-outage periods, there

4 are 6 people assigned to the outage management team.  ;

{} 5 These people coordinate the efforts of schedulers and 6 planners. During an outage, the maintenance services 7 organization is augmented by about 400 engineers and O 8 craftsmen.

9 The Material Services Section has about 118 full time 10 employees and is responsible for the procurement of O 11 material (equipment and parts), warehousing, issuance and l 12 repair of tools, and the calibration of measuring ar.d test l  !

13 equipment. Procurement, within this section, also has

() 14 responsibility for defining the technical and quality 15 requirement of material requests.

i i

O 16 021 Are there examples of organizational methods utilized  ;

l 17 at DCPP, beyond what you have just described, to foster l

18 continued improvement?

O. i 19 A21 (Giffin) Yes. As part of our commitment to continuous 20 improvement in the maintenance organization, we have l

'O 21 instituted the High Impact Tean (" HIT") concept. A HIT is i

( 22 a multi-discipline team with members from a vertical slice i

. 23 of the organization who are selected based upon the ,

5) 24 particular maintenance issue or project involved. HITS  !

! 25 are formed for complex outage tasks, to facilitate 26 teamwork for new projects, or for other complicated multi- l l

,O 28  ;

1 .

l O i l

1 discipline tasks. HITS are given the resources, l i

O 2 abilities, and authority to implement actions and [

3 improvements so that tasks are accomplished in an  !

4 excellent and improving manner. Industry and PG&E

'O 5 management have recognized the efficiency, quality, and j 6 productivity benefits of employee teams. The DCPP HIT ,

7 teams have proven to be a very successful example. By  :

O 8 having a management team which supports continuous i 9 improvement and employee involvement, coupled with HITS to j 10 look for and implement improvements, a working environment O 11 exists at DCPP where change for the better is expected.

O 13 Q22 Please describe the qualifications of the personnel .

14 involved in maintenance activities.

l l

~O 15 A22 (Giffin, Crockett) PG&E has committed to the  ;

T

16 requirements of ANSI /ANS 3.1-1976, "For Selection and l l

17 Training of Nuclear Power Plant Personnel." The  !

O IB qualifications of the DCPP maintenance staff are quite -

l 19 high, and exceed the ANSI /ANS 3.1-1976 requirements. Five 20 of the seven section directors in the Maintenance Services' l O 21 Department have been either licensed or certified SROs, 22 three have advanced technical degrees, and they all have l

. 23 over 15 years experience in the nuclear industry. The I

k) 1 24 maintenance foremen and general foremen have, on average,

25 15 years of nuclear experience. The qualification of i 26 maintenance craftsmen who perform specific maintenance O 29
3 ' l l

l 1 tasks are ensured by a rigorous training program. In the 2 NRC's last Systematic Assessment of Licensee Performance

,O T i 3 ("SALP") report on the Maintenance area at DCPP (February 4 12, 1993), the NRC listed as a noteworthy strength:

5 " Qualifications: The training and qualification  ;

(O 6 program for Maintenance personnel was strong.  !

7 Well maintained training facilities and a j 8 dedicated training staff were significant factors l 9 in good performance, as was the sense of ownership ,

l 10 shown by Maintenance personnel." -

0 11 Maintenance training programs at DCPP have been 12 accredited by INPO. These accredited training programs 13 include Mechanical Maintenance, Electrical Maintenance, O 14 I&C, and Maintenance Supervisory Training. INPO 15 accreditation is an ongoing process that is re-evaluated ,

16 every four years. The maintenance training programs at ,

O 17 DCPP were first accredited in 1988 and accreditation was

  • l 18 renewed in 1992. As a result of obtaining and maintaining l 19 accreditation for all of the INPO identified programs,  ;

O 20 DCPP has been designated as a full member of the " National '

l 21 Academy for Nuclear Training." .

22 In recognition of DCPP's commitment to training and O 23 the quality of its programs, DCPP's training' director was 24 selected to participate with INPO and the Department of ,

27 Q23 How are maintenance personnel trained?

4 9

l 30 i O  ;

G 1 A23 (Crockett, Giffin) DCPP training programs are designed 3 2 to provide journeymen and foremen who will perform 3 specific maintenance tasks with the skills and knowledge 4 needed to successfully and safely complete their work. The 9 5 training programs meet the requirements of ANSI /ANS 3.1, 6 the state-approved apprenticeship program, and the INPO 7 accreditation criteria.

3 8 The maintenance training programs are comprised of 9 distinct components:

10

  • Apprenticeship 3 11
  • Basic (or Fundamental) Qualification for Journeyman 12
  • Advanced (or Select) Qualification for Journeyman 13
  • Supervisor Training 3 14
  • Continuing Training 15 The apprenticeship program is State of California 16 approved and is a negotiated contractual agreement with 3 17 the International Brotherhood of Electrical Workers. Once 18 in an apprenticeship, individuals are given two or three 19 years of training and guidance in their chosen field.

3 20 Examples are:

1- When job vacancies for craftsmen occur, they are ,

i 2 filled by graduates of the apprentice program. However, g

3 sometimes these vacancies are filled by journeymen from  :

i 4 outside of the DCPP maintenance organization. These ,

g. 5 journeymen may come with a variety of backgrounds.

6 Although they are considered to be journeymen, their 7 specific skills, knowledge, and experience may be  ;

8 different than that specifically required for basic O

9 qualification at DCPP. Thus, all such personnel are 10 tested upon entry into the Maintenance Services l t

11 Department. The test results, along with interviews by O ,

12 supervision and review of previous work documentation, f 13 determine the initial training needed to meet the 14 requirements f r Basic (or Fundamental) Qualification for O  !

15 Journeyman.

16 The topics of the Basic qualification training 17 Program, and the amount of training available, are shown O

18 in Exhibit 8. Once an incoming journeyman satisfies the i

19 Basic (or Fundamental) qualifications, further' advanced [

r 20 training on selected plant components is given based on O

21 need. Examples of advanced or plant-specific training,  ;

i 22 and the time available, are shown in Exhibit 9. [

23 In addition to plant-specific training on components z) 24 and equipment, all maintenance workers attend continuing  :

25 training seminars on a quarterly basis, except during_

g 26 outage periods. These seminars are used to address plant 27 and industry issues, changes recently made to the i 28- facilities or equipment, and recent " lessons learned." {

32 O- l

O i

1 These seminars also afford management an opportunity to r

O 2 stress areas of concern.  ;

3 Q24 How do you utilize " hands-on" training at DCPP? ,

O ,

4 A24 (Crockett, Giffin) All aspects of DCPP maintenance 5 training programs stress " hands-on" training activities.

O 6 The majority of the classes are taught in a lab or shop 7 facility and take advantage of plant-specific training 8 aids. The classes consist of lectures with examples,  !

O 9 coupled with actual hands-on experience on equipment 10 utilizing actual plant procedures and work packages 11 similar to those used to perform maintenance in the plant.

O 12 Examples of plant specific equipment available in the  ;

13 training facilities are:  !

14 e Reactor Coolant Pump (seal and motor alignment  ;

O 15 portions) 16 o Steam Generator Channel Head and Tubesheet 17 e 10% Steam Dump Valve O 18

  • Limitorque valves and operators 19
  • Nuclear Instrumentation and Protection Systems 22
  • Diesel Engine 23 With the extensive training aids available in our O 24 training program, the majority of tasks requiring  !

25 qualification can be fully accomplished in the training j

\

26 facilities. However, in soi.e instances additional "on the i I

O 33 l

l J

O 1 job" training in the plant is required prior to ,

O 2 qualification. An individual's qualifications are tracked 3 by a qualification matrix that identifies the tasks an 4 individual is qualified to perform. The foremen makes use O .5 of this matrix when assigning work to assure that only  !

-i 6 qualified personnel are assigned to a job. When possible, ,

7 workers are also given the opportunity to train on new  ;

O 8 equipment prior to its installation in the plant.

9 This extensive training program demonstrates a strong 10 commitment to the development of the skills and knowledge  !

O 11 of maintenance personnel. In the 1993 SALP report, the j 12 NRC recognized the strength of PG&E's training in the 13 maintenance area noting: ,

O 14 " Plant Safety: Maintenance personnel were trained 15 and informed regarding overall plant safety system 16 availability and the significance of their 17 individually assigned work relative to its risk to 18 the plant."

O f 19 Maintenance Facilities 20 Q25 What are the facilities that support the maintenance ,

o, 21 programs at ocPP?  ;

r t

22 A25 (Giffin, Crockett) PG&E has provided excellent O 23 facilities for the performance of maintenance activities.

24 State of the art training facilities, machine shops, l 25 calibration facilities, and warehouse storage areas are

'O 26 available to support the maintenance program and specific 27 maintenance tasks. These facilities include:

28

  • Maintenance Shops Building O 34

3 1

  • Warehouses 2
  • Computer Center and Associated Equipment 3

3

  • Machine Shops 4 o I&C Shop 5

6 The Maintenance Shops Building is a $10 million j 7 facility, located adjacent to the plant protected area.

8 In this building are laboratories, shops, and classrooms 3

9 totaling 70,000 square feet of space devoted to the 10 training of plant personnel. Within the mechanical, g 11 electrical, and instrumentation shops and laboratories are 12 many of the same components and equipment installed and I 13 operating within the actual plant. These are used for the 1

14 troubleshooting and repair training described above. When 3

15 infrequent maintenance activities are planned, the 16 equipment in this facility is also used to rehearse the l 17 activity and refresh the skill of the craftsmen before the 3

18 activity is performed in the plant.

19 The main Warehouse is a $18 million facility with over l 3 20 100,000 square feet of storage area with a material 21 testing laboratory, a Quality Control inspection area, and 22 an environmentally controlled storage room. In addition l g 23 to the main Warehouse, there are several satellite 24 warehouses to store specialized equipment, e.g., the spare 25 generator storage building that houses one complete spare g 26 main generator, the spare rotor storage building that 27 contains three low pressure turbine rotors, Warehouse A 28 that is used to store corponents and materials that may be 6 35

l 0

1 radioactive, and Warehouse B that is used to store other. ,

C) 2 large equipment and material to be surplused. .

.3 The Computer Center and associated facilities are 4 located in the Administration Building at DCPP and occupy 0 5 25,000 square feet. The Center includes:

6

  • A fully automated mainframe computer facility housing 7 an IBM 3090 400J series machine.

O 8

  • A network operating center housing over 30 network 9 servers.

l 10

  • A computer support and help desk facility. ,

f) 11

  • An information systems prototype and testing facility. ,

i l 12

  • The data communications hub internal to the plant and ,

4

! 13 the gateway to external PG&E facilities.

4 ,

lO 14

  • Applications maintenance, development, and 15 administrative areas.

16

  • A support staff of full time personnel O 17 The cost to staff and operate the facility is 18 approximately $12.5 million per year. This cost provides f 19 us with the capability to execute business transactions at O 20 the rate of 700-800 transactions per minute and to  ;

21 maintain over 130 gigabytes of plant information available 22 for rapid on-line retrieval. Collectively, the staff and O 23 the facilities provide DCPP with state of the art 24 information technology services.

i 25 There are four machine shops at DCPP. The first is C) 26 the Cold Machine Shop Building located south of the Unit 2 27 Turbine Building. It is an $8 million facility consisting ,

28 of 35,700 square feet and is shared by the Electrical and O 36  ;

O 1 Mechanical Maintenance Sections. The second is O 2 strategically located between both units in the Turbine 3 Building. A third facility is located at the intake 4 structure and consists of 2760 square feet at a cost of Q 5 S720,000. These three " cold" machine shops are used to 6 work on equipment that is not radiologically contaminated.

7 Radiologically contaminated equipment is brought to a O 8 fourth facility, the " hot" machine shop, where special 9 controls are in place to clean the equipment, prevent the 10 spread of contamination, and protect the workers. All O 11 four machine shops have proper equipment, such as lathes 12 and drill presses, with appropriate environmental 13 conditions conducive to ensuring maintenance quality and O .14 work efficiency.

15 The I&C Shop is an $8 million facility with over 16 25,000 square feet of I&C repair shops (for repairs and O 17 instrument calibrations), telecommunication shops, a 18 medical facility, and office area. The I&C shop was 19 constructed to consolidate all I&C functions in one O 20 location to enhance communication and overall work 21 efficiency.

22 Part of the I&C Shop is the Measuring and Test O 23 Equipment ("M&TE") calibration lab. Here, high accuracy 24 calibration is performed on equipment that, in turn, is 25 used to calibrate plant equipment. Over 700 pieces of O 26 M&TE are calibrated monthly during non-outage periods, and 27 about 5,000 per month during outage periods.

O 37

! t V i 53 1 In addition to these facilities, DCPP has various I i

2 laydown areas, tool storage, repair and issue stations, O

3 and temporary facilities that are used during outages.

4 Together, all of these facilities ensure the effective and 5 erficient performance of maintenance activities.

O 6 Preventive and Corrective Maintenance 7 Q26 The next element is achieving a " proper mix" of O

8 preventive and corrective maintenance. How is this 9 element satisfied at DCPP?

i O

10 A26 (Ortore) Maintenance is generally defined as falling 11 into two categories, preventive and corrective.

12 Preventive maintenance tasks are periodic, planned, or O '

13 predictive actions taken to ensure that equipment 14 continues to maintain its design function. Preventive i

15 maintenance tasks are normally performed on a O  :

16 predetermined scheduled basis prior to any equipment 17 failure or degradation. Annually we perform about 14,000 18 preventive maintenance tasks at DCPP. These activities 1 0

19 range from simple equipment inspections, replacement of 20 limited life items such as lubricants, filters, wear l 21 rings, bearings, and diaphragms, to major equipnent

O 22 overhauls. Preventive maintenance tasks are selected so .

l 23 as to maintain equipment in a condition which will l

! 24 increase reliability and extend the life of equipment.

g 25 A Master Equipment List ("MEL") identifies and tracks

[ 26 the majority of plant equipment, both safety-related and l

l 38 O >

1 I

9 1 nonsafety-related. Starting with the MEL, the following 9 2 equipment is selected to be included in the preventive

)

3 maintenance program: (1) any installed equipment, either 4 NSSS or BOP equipment, needed for safe and reliable plant

,e 5 operation, (2) any equipment requiring preventive 6 maintenance based on PG&E commitments, (3) any equipment 7 whose malfunction can cause direct personnel injury, and

[] 8 (4) any equipment where the implementation of preventive 9 maintenance may cause a reduction in operating costs.

10 There are about 17,500 components included in the DCPP

[) 11 preventive maintenance program.

12 A program of predictive maintenance has also been 13 incorporated into our maintenance program at DCPP as a

[) 14 part of preventive maintenance. Predictive maintenance is 15 the continuous or periodic monitoring and diagnosis of 16 selected equipment parameters to provide early detection

[) 17 of equipment degradation prior to equipment failure. This 18 is accomplished by gathering and analyzing information, 19 predicting future degradation, and then taking action to

) 20 limit the degradation before partial or complete failure 21 occurs. For example, this could involve taking a 22 lubricating oil sample from a piece of rotating equipment

) 23 such as a pump or motor (which is a standard task),

24 analyzing the sample for metal wear products and other 25 particulates to determine the amount and type of wear

  1. 26 occurring, and trending these findings to determine the 27 degree of degradation that may have taken place. If 28 necessary, we will then recormend specific maintenance D 39

9 1 actions for equipment. Generally, DCPP utilizes a variety O 2 of nonintrusive equipment monitoring techniques including:

3

  • Lubrication analysis (as just discussed) 4
  • Vibration monitoring and diagnostics
  1. 5
  • Air and motor operated valve diagnostic testing 6
  • Acoustic analysis 7
  • Bearing temperature analysis 9
  • Insulation resistance 10
  • Non-destructive analysis C) 11
  • Monitoring and trending of equipment data 12 The predictive maintenance program is described in 13 procedure, AP C-751, " Predictive Maintenance Program."

C) 14 Corrective maintenance consists of the repair and/or 15 restoration of equipment. As discussed above, this is a

, 16 normal and expected part of the maintenance program.

) 17 Corrective maintenance is performed when equipment is not 18 able to perform its intended function or is outside 19 operating limits. The maintenance action will return the C). 20 equipment to a specified performance level. For example, 21 if a valve packing is leaking and needs to be tightened, 22 that task would be listed as corrective maintenance. We

2) 23 perform on the average 7,000 corrective maintenance tasks 24 at DCPP each year.

O 25 How do we know that at DCPP we have achieved a " proper Q27 26 mix" of preventive and corrective maintenance?

'O i i

i 1- A27 (Giffin, Ortore) Within the nuclear industry, a high  !

C) 2 ratio of preventive maintenance (including surveillances) l l

3 to total maintenance is indicative of an efficiently  !

4 managed maintenance program which is effective in l l

0 5 maintaining the plant in a safe and reliable condition.

I 6 Obviously this is a very subjective assessment. It is in 7 our interest to minimize corrective maintenance, to the [

C) s extent practical, through preventive maintenance.

9 However, preventive maintenance cannot avoid all I

{

10 corrective maintenance, nor would such a goal be practical O 11 from an operating perspective. INPO formerly monitored 12 this parameter and had established 60 percent as the }

13 objective.  !

O .14 At DCPP, we monitor preventive maintenance tasks as a -

15 percentage of all maintenance tasks and strive to maintain  ;

1 16 the ratio above 60 percent. Over the past three years the C) 17 number of corrective maintenances performed have decreased  ;

i 18 which can be attributed to the effectiveness of the  !

I 19 preventive maintenance program. Based on-this performance O 20 and the experience gained since we began monitoring this 21 percentage, we believe that we are maintaining a proper  !

22 mix. We believe also that the overall reliabilit'y of the 0 -23 plant to date, as measured by the plant availability and

! 24 plant capacity factors, is a good indicator of a proper }

[)

l 5 A28 (Vosburg) In order for maintenance activities to be )

9 expended considerable effort at DCPP over the last several 10 years in the preparation of state of the art maintenance

, 11 procedures. There are currently about 6,000 written i l

l 12 procedures which are used to conduct specific maintenance i i 13 activities. Exhibit 10 to this testimony is a list of j 14 these maintenance and surveillance test procedures. These 15 procedures are periodically reviewed and updated, as 16 necessary. The procedures that the craftsmen use have

17 been prepared with input from the workers and provide the 18 necessary graphics and check lists. The relevant

(

19 procedures for specific tasks are incorporated, as

)

20 appropriate, into task-specific work packages described 21 below.

22 Plannina and Schedulinq 23 Q29 The next element concerns planning and scheduling of 24 maintenance tasks. How is this accomplished at DCPP7 L

42

O 1 A29 (Vosburg) With approximately 20,000 maintenance and i

o 2 surveillance work orders performed each year, it is 3 extremely important to plan and schedule the activities  ;

4 correctly. This is one of the important functions of the O 5 Work Planning Section of the Maintenance Services 6 Department and is part of a detailed, comprehensive work 7 control process. The work control process provides the

~

9 8 integrated mechanism under which plant maintenance 9 activities and equipment problems (including both f i

10 preventive and corrective maintenance tasks) are o 11 identified, reviewed, prioritized, planned, scheduled, 12 performed, tested and closed out. The process ensures 13 that plant maintenance activities are planned and 0 14 performed in a safe, timely, efficient and controlled f

i 15 manner. The process is specifically designed to t

16 coordinate maintenance activities to minimize the time O 17 that safety-related equipment is out of service.

18 Q30 How are corrective maintenance activities identified  !

O 19 for incorporation into the work control process?

i 20 A30 (Vosburg) A key objective in the overall maintenance l

j O 21 program is to ensure that actual or potential plant 22 equipment problems will be identified and documented in a 23 timely manner. One facet of the surveillance testing and o 24 preventive maintenance programs is directed towards early 25 identification of discrepant equipment conditions, with 26 the desired goal of repairing / replacing equipment before O 43

4 O' t 4

i i

i l 1 failure. Device calibrations also play a part in flagging ,

O 2 trends which aid in early detection and repair.

+

I 3 Maintenance tasks identified by these programs are 4 scheduled and tracked through the work control process. '

O 5 Any individual who discovers a problem in the plant is  !

6 responsible for initiating on Action Request ("AR") or 7 reporting the problem to a supervisor who must then ,

O 8 initiate an AR in a timely manner. A significant factor  ;

9 which contributes to the effectiveness of the problem f 10 reporting system at DCPP is that all personnel working at O 11 the plant nave access to the system, either directly or-At the plant site I 12 through their immediate superviscr.

13 alone, there are more than 1,800 computer terminals ,

O 14 available where ARs may be initiated and at least as many ,

15 plant personnel with direct access to the system. Since i 16 the AR system is used not only for documenting plant l t

O 17 equipment problems but also for documenting administrative  ;

i 18 tasks, requesting design changes, requesting 19 interdepartmental support, etc., there is a high level of O 20 familiarity with the problem reporting process throughout j 21 the plant staff.  ;

t O 22 031 once maintenance tasks are identified, what means 23 exist to track the scheduling, planning, and completion of i 24 those tasks?

O 25 A31 (Vosburg) The administrative controls for the work i 26 control process at DCPP are integrated into PIMS. Using -

O 44

I t

I l

1 this system, all data entered at any one computer terminal

() 2 during the process is immediately available at other i l 3 computer terminals throughout the plant. This attribute i I

4 makes the entire system highly responsive to plant

()- 5 maintenance needs. One advantage of PIMS is that the f 1

6 system itself assigns unique task numbers to new -

7 documents, thereby ensuring that none are inadvertently l

C) 8 misplaced. Once an AR is created, it cannot be  ;

i 9 destroyed - even if it is taken to " rejected" status. 1 l

10 The ARs module within PIMS ensures that problems 0 11 receive appropriate levels of review and are tracked 3 12 through resolution. The AR is the key which {

13 electronically ties together all other modules which make i C) 14 up the maintenance process (equipment clearances, work i

15 orders, quality evaluations, post-maintenance test ,

16 requirements, etc).  ;

C) 17 An overview of the DCPP work control process as it i 18 relates to a plant equipment problem is illustrated in 19 Exhibit 11. In the sequencing of a typical maintenance  !

O 20 work request, the key elements of the process are-  !

21 described below:

22

  • Upon identification of a maintenance problem, the j

() 23 person who discovers it wil2 initiate an AR at a 24 convenient terminal. After filling in as much

! 25 information as is available at that time, the AR is

) 26 left in the " initiated" status and the individual's

! 27 supervisor is notified.

O 45 l

I.

O 1

  • The supervisor reviews the AR for accuracy and assigns  ;

2 a priority to the AR in accordance with the plant work 3 prioritization system. The supervisor is also 4 responsible to ensure that Operations is inmediately -

O 5 notified of any problem that is believed to have an  ;

l 6 impact on plant safety or equipment operab'ility. This 7 notification is documented on the AR. The AR is then O This effectively #

8 taken to the " reviewed" status.

9 makes the AR available to the Work Planning Center.

10

  • The Work Planning Center routes the AR to the  !

O 11 appropriate planner, who is then able to begin 12 preparation of a work order, another electronic module 13 document which is linked to the AR. ,

O 14

  • As part of the work order preparation, the planner 15 reviews the problem as documented on the AR and begins .

16 collecting information necessary to plan the O 17 maintenance activities. This may include (but is not -l 18 limited to): a walkdown of the jobsite; identification l 19 of relevant procedures, drawings and vendor manuals; 20 identification of special processes (such as welding);

21 interviews with foreman and craft; identification of 22 administrative limitations on the job secuence; and ,

O investigation of any salient information contained in 23 24 the PIMS Component or Maintenance History Databases. l 25

  • The planner may use other specialized modules within  ;

26 PIMS to electronically research and order spare parts, 27 flag quality-related aspects to the Quality Control .

28 group, request Radiation Work Permits for radiological l C) 46

2 isolation /tagout) which will be required in order to ,

3 commence work, and notify other disciplines of the 4 need for technical assistance.

)'

t 5

  • When the planner has all necessary information ,

6 collected, he/she writes the work flow description 7 directly into the electronic work order. Quality J 8 related work orders are reviewed by the Quality 9 Control organization for the incorporation of needed 10 inspection hold points which are inserted into the ,

11 work order. The work package is then created which l 12 includes a copy of the work order, copies of 13 maintenance procedures referenced by the work order,

) 14 and other supporting documentation such as vendor 15 manuals and applicable plant drawings. The work 16 package is then assigned to the appropriate 17 maintenance foreman.

1B

  • Another electronic link ties the work order to the 19 on-site scheduling software. The job is integrated by 3 20 the scheduling staff into the overall maintenance i

21 picture to ensure that it is performed in a time frame 22 commensurate with its priority. It must be merged

, 23 into the work stream along with other tasks to be 24 scheduled, such as corrective or preventive i 25 maintenance activities and surveillance _ testing.

26

  • The maintenance task is performed by the appropriate 27 discipline, following which the work order is reviewed 2B by the foreman. The package is then returned to the

) 47

4 1 Work Planning Center for closure. The planner O 3 transcribes the results of the maintenance action into 3 the Component Maintenance History (another PIMS module 4 which provides a running history of maintenance to aid 9 5 in future planning efforts and/or research) and then 6 forwards the completed work order to Document Control 7 for archiving.

O 8 Q32 What considerations go into planning the scope of work 9 for specific maintenance casks?

O 10 A32 (Vosburg) Work pl'aning creates the integrated work 11 package based on the following considerations:

C) 12

  • Consistency and conformance to standards and 13 requirements; 14
  • Safety, reliability and effect on generation O 15 capability; 16
  • The quality classification of the work, to assure that 17 the plant quality organizations are integrated into O 18 the work planning process; 19
  • Integration with work scheduling to maximize the 20 efficiency of all work performed; and O 21
  • The safety and radiation protection of plant workers.

22 Q33 Explain how maintenance tasks are scheduled.

G 23 A33 (Vosburg) The overall objective of the work scheduling 24 function is to coordinate and schedule plant work O 48

r s

i O

i l

1 activities in a manner that maximizes efficient O 2 utilization of plant resources and enhances the safe and 3 reliable operation of the-plant. To accomplish this we 4 developed a computerized scheduling program which ,

O 5 interfaces with PIMS. Periodic schedules identify when [

-6 equipment maintenance, testing or inspection is required. i 7 These computer schedules are routed to appropriate C) 8 sections for planning and performance of the work. The 9 scheduling program allows for integration of all work 10 activities into the schedule.

C> 11 The framework for the scheduling of plant maintenance i 12 and surveillance activities is built around a process  ;

13 known as the Mode one Integrated Daily Schedule ("MOIDS"). ,

O 14 This process uses a 12-week rolling matrix which 15 identifies the required Technical Specification 16 surveillance tests for plant equipment and reserves blocks O 17 of time within the base schedule for the performance of 18 these tests. All other maintenance activities related to 19 the equipment are then identified and incorporated into O 20 these maintenance windows. Typical activities to be 21 included would be the routinely scheduled preventive 22 maintenance activities and any necessary corrective O 23 maintenance activities. Using this method, both the 24 number of times that equipment is removed from service and 25 the amount of time that the equipment is unavailable are O 26 minimized. Using the MOIDS concept, plant schedulers 27 along with senior licensed personnel from operations meet 28 twice a week to develop the schedule for the upcoming O 49

)

1 week. All activities to be performed on safety-related

) a equip:ent are reviewed by the group for plant safet) 3 impact. All preventive maintenance activities to be 4 included are reviewed to assute that work necessary to

) 5 enhance the reliability of the equipment is performed 6 within the normal maintenance window and is not 7 unnecessarily deferred.

) 8 An additional enhancement to the scheduling process 9 has been the assignment of a licensed Operations 10 representative to the scheduling group. This innovation

) 11 has proven instrumental in the improvement of 12 c immunication between the Planning, Scheduling, and 13 Operations organizations. The Operations representative

) 14 provides guidance to ensure that work is scheduled in a 15 way that optimizes use of Operations and Maintenance 16 manpower. He or she also provides input to the schedule 3 17 from a risk assessment standpoint and reviews scheduled 18 work to identify potential safety system interactions.

19 This aids in the early identification and resolution of

) 20 schedule conflicts and improves the overall efficiency and 21 safety of the final schedules.

) 22 Q34 How do you monitor work to control the backlog of 23 maintenance activities? I

) 24 A34 (Vosburg) The work control system at DCPP provides the 25 means for identifying, tracking, and controlling the 26 maintenance backlog. The backlog of corrective and I

) 50 l

O 1 preventive maintenance is tracked separately with specific 2 goals for each as established by management at the

)

3 beginning of each year, with the general intention of 4 reducing each as low as practicable. Since all 5 maintenance items at DCPP are individually tracked through 6 PIMS, status reports can be generated quite readily and 7 are available for management review.

O 8 Post-Maintenance Testing 9 Q35 Please detaribe the DCPP post-maintenance and post-10 modification testing program.

11 A35 (Crockett, Vosburg) Post-maintenance and 12 post-modification testing ("PMT") is a key component to 13 implementation of the plant maintenance program. The 14 primary objective of PMT is to ensure that all plant 15 equipment which Sas undergone maintenance or modification u

16 activities ha s be;" demonstrated to be fully functional or 17 operable prior o ~5ts :n to service.

18 Technical Specificatlens specifically require that

,O 19 safety-related equipment be properly tested and any l 20 associated problems resolved following maintenance or modification prior to declaring the equipment operable.

l,3 21 22 However, PMT at DCPP is not limited to Technical 23 Specification equipment. From an overall plant safety and 24 reliability standpoint, it is a good practice to perform 25 PMT following maintenance or modification of plant 26 equipment not required by the plant Technical 51 3

O 1 Specifications to ensure that the equipment will fulfill 2 its design function prior to returning the equipment to 3 service.

4 Generally, PMT requirements are specified in the work 5 order and in each case will be commensurate with the O

6 maintenance or modification work completed and the 7 importance of the equipment to plant safety and 8 reliability. At DCPP, PMT consists of two different types 9 of testing: Maintenance or Modification Verification  ;

10 Tests ("MVT") and Operability Verification Tests ("OVT").

11 MVTs are typically those tests, inspections, or

.O 12 verifications which are performed by the implementing l 13 organization without actually operating the equipment.

14 For example, typical MVTs would include cleanliness

,.O 15 checks, electrical continuity and megger checks, and 16 instrument loop tests. OVTs are those tests specifically 17 designed to prove Technical Specification operability.

18 OVTs usually consist of performing the appropriate 19 Technical Specification surveillance test.

l O

l 20 Q36 How is PMT planned, controlled, and tracked?

f l

l (O '

21 A36 (Crockett, Vosburg) Identification and tracking of the 22 necessary testing begins with the work planner during the 1 23 development of the work package. Based on the scope of O

24 the work, the planner must decide prior to issuing the l 25 package to the field whether PMT is required and who is 52 i

'O.

O 1 responsible for identifying the required MVTs. Normally, O 2 to determine the MVTs, the planner routes the work package 3 to the appropriate review group to identify any necessary 4 in-process inspections, parts dedication tests, and static O 5 and dynamic tests specified in applicable industry codes, 6 standards and vendor ranuals. These tests and inspections 7 are normally included in the work order created on PIMS.

8 VTs are also identified and tracked by the PMT nodule O

9 within PIMS.

10 Documented completion of the required PMT is an 11 essential component of the equipment control process used O

12 by Operations when returning equiprent to service. Prior 13 to returning equipment to service, Operations will verify 14 that all the work is completed and that the PMT has been

()

15 successfully performed.

16 In total, the process for identification and tracking 17 PMT is tied directly to the work perforned and includes

()

18 rultiple cross-checks to ensure that adequate testing is 19 accomplished.

O 20 Procurement of Parts l

21 Q37 The next element requires that correct and qualified

'g 22 parts be readily available to support maintenance. How is 23 this achieved at DCPP?

g 24 A37 (Ortore) In order to assure high reliability of j 25 operation, equipment downtire must be mininized.

26 Accordingly, when a component is removed from service for ,

l 53 I 3

i l

1 maintenance, it is important that any parts necessary to j 2 restore or repair the component be readily available. The l 3 DCPp Warehouse and parts ordering system provide a l

l 4 comprehensive and reliable means for accomplishing this i

5 goal.

l 6 When a work order is produced, any parts that are l

l 7 required for the work are identified and that information 8 is electronically transmitted to the Warehouse. The parts 9 are staged for the craft foreman prior to the start of the i

10 work so they are verified and ready for installation 11 before removing a system from service. The computer j

12 system also orders any parts which have dropped below a 13 preset limit. The onsite warehouses together have more i

14 than 200,000 square feet of storage space and contain 15 about 59,600 different items (worth about $100 million) in 16 spare parts inventory.

f-h l 17 Q38 How do you assure that replacement components and 18 parts are procured in accordance with original design 19 requirements so as to maintain the design basis?

20 A38 (Ortore) To assure that replacement parts meet 21 original design requirements, a quality assurance program,

} 22 together with a careful engineering review of replacement 23 parts is used. Many American manufacturers and suppliers 24 of items to the nuclear industry have 10 CFR 50, Appendix

)

25 B, quality assurance programs that are audited by PG&E.

26 These manufacturers become our " qualified suppliers."

1 Safety-related components or parts purchased from j j 2 qualified suppliers must be procured: (1) as the identical l i

3 item, which is an exact duplicate of the original item 4 with identical quality assurance, quality control, y 5 technical and documentation requirements, and purchased 6 from the original supplier, or (2) a documented '

7 engineering evaluation (called a replacement part j- 8 evaluation) must be performed to ensure the replacement 9 part meets or exceeds the design requirements of the  ;

10 original component. In total, PG&E devotes considerable l 11 resources -- both in engineering time and money -- to 12 assure that replacement components and parts are l

13 equivalent to or better than the original. [

) i 14 Q39 How do you assure the item you ordered is the one l l

L 15 received?

i 16 A39 (Ortore) Receipt inspection is performed on all items i

17 delivered to DCPP from the supplier. Receipt inspections  :

l j 1B range from checking the model number and supplier  ;

i  :

19 documentation against the purchase order to a more l l 20 detailed inspection by the Quality Control organization l

j al for safety-related and graded quality items. Any item not r

22 fully meeting the criteria established in the purchase i i

[ 23 documents is placed on hold, thus-preventing its use in ,

24 the plant until the discrepancy is resolved.

J 1 To assist in receipt inspection, DCPP has a material 2 testing lab onsite that is used to test items. Equipment 3

3 in the lab includes:

4 e a portable X-ray fluorescent spectrometer for metallic

-s 5 material identification; a

6 e an optical emission spectrometer for metallic material 7 identification; 8 e an infrared spectrometer for elastomer identification

)

9

  • Rockwell hardness tester for determining metallic 10 hardness tests; and 11
  • Other equipment, including durometers, system g

12 scientific alloy analyzers, and normal lab facilities.

13 This lab is staffed with qualified quality control 14 inspectors.

g 15 Q40 How do you assure that the effects of age and

, 16 environment on stored items do not adversely affect the 17 quality of the item?

J.

18 A40 (Ortore) All items with shelf-life considerations have 19 the shelf-life determined based on criteria from the 20 manufacturer, industry standards [EPRI NP-6408, 21 " Guidelines for Establishing, Maintaining and Extending g

22 the Shelf Life Capability of Limited Life Items" 23 (NCIG-13)], or other sound engineering criteria. Material 24 that has an expired shelf life is segregated and not 25 released for issue without further documented evaluation.

26 When a new part or item is installed in the plant,

, 56 J

l b  !

1 preventive maintenance is appropriately scheduled to take

[): _2 into account any impact of shelf life on the design life '!

i 3 of the part or item.  ;

4 To reduce the effects of the environment on stored

[] 5 equipment, storage levels are established that correspond 6 to the specifications in ANSI N45.2.2, " Packaging, t 7  !

Shipping, Receiving, Storage and Handling of Items for i

.[) 8 Nuclear Power Plants." Four storage levels are  ;

9 established, from level A through D, with the most j 10 stringent controls placed on Level A. For materials that ,

11 are highly sensitive to environmental conditions such as

-[] 1 12 electrical components, the material is stored in Level A  !

13 storage. Level A storage provides temperature control 14 between 60 and 90 degrees and humidity control between 30 [

'[)

i 15 and 60 percent. The ventilation system is filtered to 16 provide an atmosphere free of dust. The main Warehouse at {

! i

[) 17 DCPP has an environmental room that meets or exceeds the J

.18 Level A storage requirements. The remainder of the l

19 Warehouse is storage level B, which is indoors with j

[) 20 temperature controls. (Storage level C is inside with no 21 temperature controls and level D is outdoors. For shelf l 22 life consideration, a minimum of storage level B is used.)

[] .23 To further reduce the effects of age and environment

)

24 on stored items, in-storage maintenance is performed.

25 In-storage maintenance is based on manufacturer

] 26 recommendations, past experience, and the significance of 27 the item to plant safety. In-storage maintenance can 57 h)

O 1 involve visual examinations, cleanings, rotation of g 2 shafts, and application of preservatives.

3 Control of Measurinc and Test Ecuipment 4 Q41 An ther aspect of maintenance is control of Measuring O

5 and Test Equipment (" METE"). How is this addressed at 6 DCPP?

O 7 A41 (Giffin) A program for the control and calibration of 8 M&TE has been implemented to ensure that equipment, such 9 as test meters and t rque wren hes, is functional and O

10 accurate to support maintenance activities. The DCPP M&TE 11 program is described in Administrative Procedure D-5, 12 " Control of Mechanical, Electrical and Instrument &

O 13 Controls Measurement, Test and Performance Monitoring 14 Equipment." The DCPP M&TE program has been enhanced 15 significantly over the past several years. We have g

16 invested in state of the art equipment and facilities for 17 the calibration of this special equipment. PIMS is used 18 to track and control M&TE. A highly trained and qualified g

19 staff is in place to manage and support the M&TE program.

20 These elements have improved our performance in the M&TE 21 area.

O 22 Root Cause Analysis Procram 23 g42 Another element of maintenance is a detailed root O

24 cause analysis program. How does PG&E address this 25 element especially in regard to equipment failure rates?

8 O

O 1 A42 (Giffin) One of the very important components of an

() 2 effective and comprehensive maintenance program is a 3 program which provides for a systematic analysis of 4 unplanned occurrences pertaining to maintenance. This

() 5 analysis is designed to identify the root cause of an 6 event. With a root cause, corrective actions can be 7 implemented so that occurrences of the same type can be

() 8 prevented. Root cause analysis at DCPP is controlled 9 by Procedure NPAP C-26 " Root Cause Analysis." This 10 procedure provides guidance in several analysis techniques

() 11 such as cause and effect analysis, event and causal 12 factors analysis, change analysis, barrier analysis, task 13 analysis, and human factors surveys. The procedure is C) 14 supplemented by training provided by both PG&E's Training 15 Department and outside industry experts. We have made 16 major investments in training our engineers and managers

() 17 in effective root cause analysis techniques as part of our 18 commitment to avoid repetitive problems.

() 19 Q43 How are root cause determinations made for DCPP?

20 A43 (Giffin) PG&E's root cause determinations have 21 different levels depending on the occurrence being C) 22 investigated. A root cause determination is required for 23 all quality problems. These'are classified as either g 24 Nonconformance Reports ("NCRs" - most significant) or 25 Quality Evaluation ("QEs" - less significant 59 C)

D 1 A Technical Review Group ("TRG") performs a root cause 3 2 analysis for each NCR. A TRG is a multi-disciplined group 3 established for each NCR and chaired by the DCPP 4 department with the most responsibility for the issue.

() 5 The TRG includes representatives from Quality Assurance, 6 Quality Control, and all involved departments. Agreement 7 on the root cause must be unanimous among the TRG members.

3 8 Effective corrective actions are developed by the TRG only 9 after the root cause of the event is determined and agreed 10 upon. The Plant Staff Review Committee ("PSRC") reviews 3 11 the root cause analysis for all NCRs. If the PSRC does 12 not agree, the TRG reconvenes to resolve the differences.

13 The PSRC also reviews the corrective actions recommended g 14 to ensure they are adequate to prevent recurrence.

15 A root cause determination is performed for all QEs by 16 the responsible department. Corrective actions are g 17 established after the root cause is determined. Root 18 cause determinations for all QEs are reviewed by the 19 Quality Control Department.

O 20 Maintenance History / Failure Trending 21 Q44 What does PG&E do in the area of component maintenance

7) 22 history and failure trending?

23 A44 (Crockett) A major component of root cause analysis 24 and component failure trending is the history of the 3

25 components. Currently there are approximately 187,000 26 individual components in the DCPP Component Data Base, 3 60

[) '

l  :

1 each with its own maintenance history available in PIMS. l 1

[) 2 The information is readily available on PIMS when a i

3 problem occurs with a particular component. For example,

! 4 it is possible to determine the maintenance history of an [

i

[] 5 individual valve, or all valves with the same  ;

6 model/ manufacturer, or all valves in a system. Component ,

l 7 experience is also available from an industry wide i

() 8 database, the Nuclear Plant Reliability Data System 9 ("NPRDS"), maintained by INPO.

t 10 PG&E uses component history data for two systematic

() 11 failure trending in several respects. First, all failures 12 of components necessary for accident mitigation or whose  !

13 loss of function could initiate significant plant

() 14 transients are reported and included in NPRDS. The 15 failure report contains extensive detail, including

1 16 manufacturer, model number, serial number, supplier , j l

C) 17 application, failure mode, detection method, corrective

18 actions, symptoms of failure, systems affected, narrative  !

19 of the failure, and cause.

l  !

() 20 DCPP examines every component failure report in the 21 NPRDS database that results in a major transient. If the  !

! 22 same component is used at DCPP in a similar application,

[) 23 PG&E investigates the failure to determine if our l l

24- application, maintenance practices, or surveillance  ;

25 testing assure we will not have the same transient. When

) 26 corrective actions are required, the normal processes are 21 used. l

[) 61 1

I

l

)

i 1 Second, DCPP design and maintenance departments 2 routinely research failure rates in components as part of 3 the design or parts replacement process. Any DCPP 4 components failing at a rate higher rate than the industry 5 average are evaluated and an appropriate evaluation is

)

6 initiated.

7 Third, Nuclear Safety Engineering researches component 8 failure rates using the DCPP component history. Failure 9 rates are initially screened by computer using 10 continuously upgraded evaluation techniques. Components 11 that are identified in this process are then screened by 12 engineers. This methodical evaluation process will detect 13 failure trends occurring within systems by component type, 14 manufacturer /model, and by other groupings. This is an 15 approach designed to detect any aging failure mechanisms.

16 V. MAINTENANCE AND EOUIPEENT AGING MANAGEMENT AT'DCPP 17 Maintenance and Surveillance Programs and Activities 18 Q45 How does maintenance and surveillance at DCPP address 19 equipment aging? g 30 A45 (Giffin) As described above, equipment aging 21 management is inherent in maintenance and surveillance.

.l 22 PG&E has long recognized the benefits to be gained from ,

23 initiatives to identify and address the effects of 24 age-related degradation of SSCs. A commitment to aging ,

i 25 management has existed since construction at DCPP began.

62

) i i

3 l 1 As a result, PG&E has many nature maintenance and D 2 surveillance programs and practices in place at DCPP that 3 address equipment aging.

4 Some of the more significant programs and activities D 5 that assist in mitigating the effects of age-related 6 degradation include:

\

7

  • The preventive maintenance program provides the D 8 necessary inspection, testing, and monitoring ,

9 activities and periodic equipment servicing and 10 refurbishment to maintain the reliability of the D 11 equipment.

12

  • The predictive maintenance program seeks to forecast 13 the functional ability and necessary maintenance of D 14 SSCs.

15

  • The corrective maintenance program addresses the 16 repair of plant SSCs. Corrective maintenance can l

[) 17 provide valuable input to the aging management program 18 regarding potential aging effects.

19
  • Surveillance test programs, including ISI/IST, help to l

D 20 detect any degradation that might affect SSC 21 operability or reliability.

j 22

  • Fatigue monitoring provides on-line fatigue cycle I) 23 monitoring of sensitive components.

24

  • The EQ program defines qualified life and service 25 criteria for certain electrical equipment.

p 26

  • A reactor vessel embrittlement management plan 27 outlines PG&E's long term strategy to assure the

) 63

l.

O P 1 integrity and operational life of DCPP's reactor 2 vessels. t 3

  • A Motor Operated Valve ("MOV") testing and evaluation 4 program identifies and mitigates performance problems 5 with safety-related MOVs through design reviews and ,

6 testing activities.

7

  • A steam generator Strategic Management Plan employs 8 inspection results, industry experience, and ,

9 engineering analyses to predict steam generator 10 degradation trends and recommend aging mitigation 11 strategies.

12

  • Structural monitoring addresses the condition and 13 integrity of important plant structures.

14

  • An erosion / corrosion program addresses the aging 15 effects of erosion / corrosion mechanisms in piping 16 systems.

17 Each of these programs or activities produce specific 18 results and corrective actions to maintain and/or restore 19 equipment to its required performance level. These 20 measures address aging effects regardless of whether the O

21 aging occurred prior to or during plant operation. In 42- addition, results from these programs are used to develop 23 new or enhanced strategies to improve maintenance and  ;

24 monitoring activities, highlight strategic issues, and i l 25 increase understanding of aging mechanisms to insure that l  !

26 necessary actions are taken for mitigation. ,

f l 1 Plant /Ecuipment Improvements to Date

): 2 Q46 Since plant startup, has PGEE made or planned plant 3 equipment modifications or replacements at DCPP which 4 improve reliability or reduce the likelihood of future l

). 5 age-related degradation?

! 6 A46 (Giffin) Yes. A number of major plant modifications

) 7 designed to improve reliability or upgrade safety-related 8 equipment have been made during the eight years since DCPP

! 9 began operation. Several others are planned in the near 3 10 future. Some of the more significant modifications 11 include:

12 e Copper Removal - This project involved replacement of 3 13 all feedwater heaters and retubing of all moisture 14 separator reheaters. These changes resulted in the 15 removal of essentially all copper from the secondary

[F 16 side of the plant to increase the life of the steam

~ 17 generators.

18 e Condensate Polisher Addition - To increase the life of 3 19 the steam generators, a Condensate Polisher System was 20 added to process secondary water by ion-exchange.

l 21 e Ammonium Hydroxide Storage - To regenerate condensate

[1 22 polisher resin, a 6,000 gallon bulk storage tank for.

23 ammonium hydroxide'was added.

l

24 e SG Blowdown Rate Increase - To improve secondary water chemistry and thus increase the expected life of the

l 1

  • Control Room Upgrade - A detailed control room design i

I) 2 review ("DCRDR") was performed in accordance with the 3 requirements specified in Supplement 1 to NUREG-0737.

l 4 Weaknesses in the man-machine interface between j) 5 control room operators and equipment were identified 6 in the DCRDR. Following review and approval by the ,

1 7 NRC, control room equipment upgrades have been j) 8 implemented.

i 9 e High Density Spent Fuel Pool Racks - The original fuel'

! 10 racks in each unit's spent fuel pool were replaced 11 with high density racks, increasing the capacity in -

3 12 each spent fuel pool from 270 to 1324 fuel assemblies. ,

13

  • Improved Fuel Design - The reactor fuel used in each 14 unit is being replaced with an improved VANTAGE 5 3 ,

15 Westinghouse design.

16 e Baron Injection Tank (" BIT") Removal - In response to j 17 industry experience and NRC recommendations, the BITS  ;

18 in both Diablo Canyon units were removed from service 19 to reduce the potential for boric acid crystallization  ;

l j 20 in the Emergency Core Cooling System ("ECCS") piping 21 and valves which could potentially have degraded ,

22 safety-related equipment operability.

3 23

25 reduced from 12 to 4 weight percent to reduce the 3 36 potential for boric acid crystallization in safety-27 related components.

t

J 1 e Digital Feedwater Control System - A digital feedwater 2 control system was installed to improve feedwater g

~

control performance and reliability. The enhanced 4 feedwater control features provided by this system

.. 5 reduces the likelihood of steam generator level-J 6 related reactor trips.

7

  • Computer Replacement - The original plant process 8 computer was replaced with one having improved 3

9 man-machine interface, greater capacity, faster 10 response time, improved print and report capability, 11 improved retrieval of historical data, and complete J,

12 redundancy to prevent loss of information due to 13 single failure.

14 e ATWS Mitigation System Actuation Circuitry ("AMSAC") -

i 15 The AMSAC System was installed in both Diablo Canyon 16 units to ensure reactor protection during an 17 anticipated transient without scram ("ATWS") event l 18 that results in the loss of the secondary side heat 19 sink. AMSAC is designed to trip the main turbine, 20 initiate auxiliary feedwater flow, and isolate steam j 21 generator blowdown and sample lines during an ATWS l

22 with a low steam generator level condition.

i

% 23 e Chlorination System Modifications - Modifications to j

24 the Chlorination System include (1) the use of liquid 25 hypochlorite to control microbiofouling instead of 26 gaseous chlorine, (2) implementation of continuous g

27 chlorination of the auxiliary saltwater system to 28 control macrobiofouling (invertebrate marine life),

3 the Circulating Water System.

4

  • Fatigue Monitoring - PG&E has installed an on-line 5 fatigue monitoring system at Diablo Canyon that will 6 continuously analyze plant operational data to track 7 fatigue usage of critical reactor coolant system B components.

9

  • Additional Diesel Generator - Addition of a sixth 10 diesel generator will provide each unit with three 11 dedicated diesel generators. This will enhance 12 reliability of the onsite power distribution system by 13 eliminating dependence on a swing diesel generator and 14 the associated procedural complexities. Installation, 15 testing, and tie-in of the sixth diesel was completed l

16 in April 1993.

l 17

  • Plant Process Protection System Upgrade - This project 18 will upgrade the Process Protection System by l

l 19 replacing the existing HAGEN 7100 equipment with a l 20 Westinghouse Eagle 21 system. New steamline break h.

l 21 logic and steam generator low-low level trip time f 22 delay options will be included in the upgrade. These l

23 changes will improve the reliability and availability 24 of the Process Protection System. The digital 25 microprocessor-based system with computer-enhanced 26 testing will also minimize the likelihood of personnel 27 error during surveillance testing. System 68

[) j 1 installation is scheduled for the spring of 1994 for l l

2 Unit 1 and the fall of 1994 for Unit 2.

O l 3

  • RTD Bypass Elimination - This project will replace the l

4 resistance temperature detector ("RTD") bypass loop 5 piping with fast response RTDs installed in the hot ,

O

~

6 and cold legs of the Reactor Coolant System. Plant i 7 downtime and radiation exposures will be reduced and l 8 numerous snubbers can be eliminated. Installation is D 9 scheduled for the spring of 1994 for Unit 1 and the 10 fall of 1994 for Unit 2.  ;

11 e Radiation Monitoring System ("RMS") Upgrade - This D 12 project will upgrade the present RMS to improve ,

13 performance and reliability, and reduce required 14 maintenance. Most of the work is scheduled to be O 15 completed by 1995.

16 Many of these major modifications, made subsequent to C 17 the issuance of the operating licenses for DCPP, 18 constitute upgrades in plant equipment or operating l 19 systems which will help minimize the effects of -

D 20 age-related degradation on the plant over the remainder of ,

l 4 23 Aging Management Procram Directive '

l 24 Q47 Has PGEE formalized its aging management efforts?

t i

69 i a

i I

O 1 A47 (Giffin, Crockett) Yes. The overall aging management t O 2 program for DCPP was recently established pursuant to 3 Program Directive TS1, " Plant Aging Management." This 4 program encompasses and augments the many existing O 5 programs (listed in A45 above) that address age-related 6 degradation over a 40-year operating life. j 7 The DCPP aging management program collects data and O 8 utilizes input from many resources to insure that PG&E  !

9 stays on the " cutting edge" of new developments and 10 technologies for detecting and responding to age-related  :

O 11 degradation. New research findings, industry operating 12 experience, and information from the NRC, EPRI, 13 Westinghouse, i.nd other sources are considered for O 14 inclusion in appropriate programs. A process is also 15 defined to integrate PG&E and industry experience into the 16 existing DCPP maintenance and surveillance programs.

O 17 A major element of this enhanced aging management 18 program involves increased emphasis on aggressive 19 participation in activities that capture new technological O 20 advances and tools developed to improve nuclear plant life 21 cycle management / aging management capabilities. As a 22 result, during the first half of 1993 PG&E pursued this O 23 objective through the following initiatives:

24

  • In January 1993, PG&E joined the EPRI Life Cycle 25 Management (" LCM") subcommittee. EPRI is a recognized O 26 leader in research and development activities 27 involving all aspects of the power industry. The LCM 28 subcommittee has been established as a forum to O 70

)

1 develop and/or assemble state of the art technical j 2 information , tools, and methodologies to assist 3 nuclear power plant licensees in optimizing plant 4 performance by identifying, evaluating, and mitigating

) 5 the effects of plant aging to support continued safe, 6 reliable long term nuclear plant operation.

7

  • Acting on a PG&E initiative, the Region V Engineering

) 8 Manager's Forum (" EMF"), consisting of representatives 9 from Region V licensees, recently authorized the 10 establishment of an aging management subcommittee.

11 One of the primary objectives of this subcommittee is

)

12 to share, collaborate, and disseminate information .

13 regarding issues and developments involving aging

) 14 management.

15

  • In February 1993, utility owners who are members of l 16 the Westinghouse Owners Group authorized an $8 17 million, five year project to manage nuclear plant

)

18 life cycle management / license renewal issues facing 19 the industry. One of the primary objectives of this program is to develop technical reports (based upon

) 20 21 ongoing research, technical evaluations and plant -

22 experience) and other tools that guide member l 1

23 utilities in their efforts at managing aging in

) '

24 important plant components. PGLE has taken a i 25 leadership role in this effort by serving on a core l

26 project management team.

I 71 l

O 1 The above initiatives enhance the existing, ongoing 2 PG&E efforts to identify, evaluate, and implement evolving 3

3 aging technologies, tools, and methodologies.

4 Q48 Are there other programs at DCPP to address O

5 aging / maintenance of specific equipment?

6 A48 (Giffin) Yes. As we stated at the outset of this O

7 testimony in A7, for certain critical components subject 8 to complex aging mechanisms, or for certain components I 9 with a limited life (e.g., some EQ equipment), special O

10 maintenance programs have been implemented at DCPP. Some 11 of these nature programs are also listed in our response 12 A45 listing existing programs that effectively address O

13 equipment aging. We will now describe a few in greater 14 detail.

O 15 Steam Generator Tube Degradation 16 Q49 How does PG&E address steam generator tube 17 degradation?

O 18 A49 (Giffin) At DCPP, steam generator tube degradation is ,

19 monitored and managed by careful chemistry control during g

20 operation and by an extensive cleaning and inspection 21 program during each refueling outage.

22 During plant operation, chemistry conditions in the O

23 condensate, feedwater, steam generators, makeup water, and 24 other systems are monitored and controlled in accordance l 72 b

i O i i

1 with the chemistry guidelines published by EPRI (PWR O 2 secondary Water Chemistry guidelines - Revision 3, May 3 1993). These guidelines reflect state-of-the-art industry

4 thinking with respect to measures for reducing corrosion i .

.O 5 and for enhancing steam generator reliability.

6 During refueling outages the following techniques are 7 used for tube cleaning and inspection:

O 8 . " sludge lancing" to remove sludge accumulated during 9 operation; 10 * " Pressure pulse cleaning" to aid in sludge removal in 0 11 the upper area of the tube bundle; and  ;

12

  • Eddy current inspection to assess the condition of (

13 tubing (PG&E is actually inspecting by this technique O 14 a much larger scope than required by applicable 15 guidelines to proactively assure detection of trends).

16 PG&E is also an active member of the EPRI Steam ,

i O 17 Generator Reliability Project. Participation in this and  ;

18 other industry groups helps keep PG&E aware of new l 19 developments related to steam generators. As new i O 20 understanding of steam generator tube degradation emerges r l 21 and new processes and recommendations for mitigation of 22 age-related degradation are developed, PG&E has actively [

l  ?

O 23 pursued prompt implementation of such initiatives.  !

I 24 Examples of steam generator maint 2 nance initiatives at ,

25 DCPP are heat treatment of row I and 2 tube U-bends and ,

L() 26 "shotpoening" of-all hot leg tube ends.

I 27 PG&E has also prepared a comprehensive Steam Generator ,

28 Strategic Management Plan which compares the status of

.O 73 i t

l  :

t C) i i

1 DCPP steam generator tube degradation with that of other O 2 steam generators throughout the industry and predicts ,

3 performance over time. Based on the current number of .

4 so-called " defective" tubes, DCPP compares well with the O 5 industry. Tubes are defined as " defective" with 6 degradation equal to or greater than 40 percent through 7 wall. Defective tubes are required to be repaired by 0 8 either plugging or sleeving. Unit 1, with 43 tubes 9 (0.3 percent of total tubes) plugged, is in the 20th 10 percentile of the industry (i.e., 80 percent of plants i O 11 have higher steam generator tube degradation rates); Unit i

12 2, with 76 tubes (0.6 percent) plugged, falls just above l 13 the 50th percentile. If this level of performance  ;

l I

L() 24 A50 (Giffin) PG&E has and will continue to comply with NRC

( 25 regulations governing Reactor Pressure Vessel ("RPV")

26 surveillance and integrity codified at 10 CFR 50.61 and i O 74 1

O 1 Part 50, Appendix H. The DCPP Reactor Vessel Radiation O 2 Surveillance Program is designed to monitor changes in 3 material / mechanical properties of the DCPP RPVs over the 4 operating life of the plant to assure safe continued O 5 operation of the vessel. DCPP's surveillance program was 6 designed to meet the requirements of ASTM E-185, " Standard 7 Practice For Conducting Surveillance Tests For Light Water C) 8 Cooled Nuclear Power Reactor Vessels."

9 Reactor vessel integrity is also evaluated through 10 periodic 10-year in-service inspections which are required C) 11 by ASME Section XI. The in-service inspections require 12 volumetric inspection of all pressure retaining welds, and 13 all full penetration nozzle welds; volumetric and surface C) 14 inspection of all pressure retaining dissimilar metal 15 welds and visual inspection of 25 percent of the partial 16 penetration nozzle welds external surface. The first C) 17 in-service inspection was successfully conducted on both 18 units during the most recent outages, with no adverse I

i 19 findings.

I C 20 Alternative fuel management strategies are also l

21 continually being evaluated to determine the most 22 effective way to reduce reactor vessel exposure to neutron

) 23 irradiation. To date these strategies have resulted in two 24 fuel arrangement changes. DCPP implemented Phase 1 of the 25 fuel management strategy in the first reload of each unit O 26 by incorporating a " low leakage" fuel loading pattern 27 which yielded approximately a 30 percent flux reduction 28 compared to standard loading patterns. A low leakage h) 75

i O

1 loading pattern is achieved by loading relatively low O 2 enrichment fuel assemblies which have been previously 3 burned in the preceding cycle in the core periphery to 4 reduce the number of neutrons produced near the vessel l

g 5 wall. Phase 2 of the fuel management strategy was 6 incorporated into the cycle 3 design which targets flux 7 reduction measures in specific areas (i.e., the welds O 8 adjacent to the corner baffle locations).

19 has calculated the Reference Temperature for Pressurized 20 Thermal Shock (" PTS") for each veld metal and base metal 21 in the DCPP beltline region for neutron fluences O

3 Erosion / Corrosion 4 QS2 How does PGEE address piping erosion / corrosion 5 concerns?

6 A52 (Crockett) The term Erosion / Corrosion ("E/C") in the 7 context of nuclear power plants refers to the process of 8 wall thinning in susceptible piping or other pressure 9 boundary components caused by the flow of water or wet 10 steam. E/C is a normal part of the plant aging process; 1 11 consequently, its management is an integral part of normal l 12 maintenance at DCPP. All DCPP secondary-side piping h 13 systems operating above 212*F, containing single or 14 two-phase water (but not dry steam), are susceptible to I

, 15 the effects of E/C and are therefore included in a DCPP D-16 E/C Monitoring Program. Notably, safety-related piping 17 which is fabricated of stainless steel is not susceptible 18 to E/C degradation.

19 The rudiments of the DCPP E/C Monitoring Program were 20 established in 1983, well before commercial operation was 21 achieved. Later, in early 1987, PG&E formed a 22 multi-discipline E/C Task Force. The Task Force is l

23 charged with developing and maintaining a broad-based 24 perspective on E/C monitoring at DCPP. Rather than 25 relying upon any single methodology for the prediction of 26 E/C-susceptible locations, the Task Force has maintained a 77 D-

l 1 defense-in-depth approach to address E/C at DCPP. PG&E's 2 defense-in-depth philosophy includes monitoring E/C 3 experience through a number or industry and NRC sources. ,

4 The DCPP E/C inspection scope incorporates ,

5 approximately 160 components per unit in the most recent  ;

l 6 outage inspections. The most severe examples of E/C 7 degradation found at DCPP are highly localized, and i

8 typically occur downstream of control valves and at

9 reducing orifices in areas of extremely high fluid f 4

j 10 turbulence. Piping at all such locations has been or is 11 in the process of being replaced with E/C-resistant 12 material such as stainless steel or chrome-moly steel.

l L

13 These replacements are a permanent solution to the

)

14 degradation problem, as proven by continued monitoring.  :

15 The next-fastest wearing piping occurs in the high l 16 pressure extraction steam piping exiting the high pressure 17 turbine. The majority of this piping has already been h

18 replaced at DCPP with stainless or chrome-moly steel as a-19 permanent solution, as proven by continued monitoring.

)

20 The replacement of the remainder of this piping at DCPP is j 21 scheduled to be completed within the next several fuel 22 cycles.

23 The DCPP E/C Monitoring Program was identified as an L

1 24 engineering strength in the 1992 NRC SALP Report. We 25 believe the E/C program is an integral part of the PG&E 26 corporate commitment to the safe, reliable operation of i

27 DCPP.

1 Q59 Can you draw any additional conclusions about the j 2 specific events discussed by HFP (in the documents 3 referenced in Q56) relative to any pervasive patterns or 4 recurring events?

O 5 A59 (All) As we review these specific events, as well as 6 the events characterized in the problem report documents 7 referenced by the MFP, we see no pervasive or systematic 3

8 problems that would indicate a programmatic weakness in 9 our maintenance and surveillance programs. Rather, we see g 10 random occurrences or omissions that are typical of human ,

11 shortcomings when engaged in a complex array of human 1 12 activities. In some cases, a procedure was not j 13 sufficiently explicit. Other occurrences involved .

14 individual inattention to detail; while still others i 15 involved the exercise of judgment by an individual that j 16 some activity is acceptable, when a later, more thorough, 17 review determines it to be unacceptable. We conclude that 18 these are random problems of the type that one might i

j. 19 normally anticipate to occur in the implementation of a 20 nuclear plant maintenance and surveillance program. In 21 addition, a defense-in-depth philosophy was incorporated j 22 into the plant design, the plant operating program, and  ;

23 the maintenance and surveillance programs at DCPP. This l

l 24 includes redundant trains of safety equipment, cperator 25 training to recognize and respond to problems, and j 3

26 surveillance and maintenance to identify and correct 27 problems and potential problems. This defense-in -depth 80 Q i l

l

O 1 assures that individual random equipment failures and 2 personnel errors will have no effect on safe operation of C

3 the plant.

4 On the other hand, as we have previously stated, it is 5 extremely important that we learn from these problems, D 6 investigate them and understand them fully, and 7 continuously improve our maintenance and surveillance 8 programs based on what we have learned. Each identified O

9 problem has its associated corrective action, which often 10 includes improvements to procedures, training, work 11 implementation, or work control. During this evaluation O

12 process, PG&E critically assesses how it conducts its 13 activities. Thus, it should not be surprising that we 14 identify mistakes and errors and use this information to O

15 formulate new and/or better ways to conduct our 16 maintenance and surveillance activities.

17 Additionally, PG&E engages in a variety of D

18 self-critical evaluations and assessments which are l 19 designed to provide insight into and improve maintenance l 20 and surveillance at DCPP. This constant search for ways lO l

21 to improve is a hallmark of PG&E's and has contributed to l

l 22 the NRC placing DCPP on the "best plants" list for the 23 past two years. Far from being an indication of D

24 programmatic weakness, PG&E's documented investigation and 25 self-critical evaluation of the items cited by MFP, 26 indicates that the overall maintenance and surveillance O

27 program is strong, effective and comprehensive.

1 Containment Fan Cooler Units Backdraft Dampers ,

2 Q60 For each of the specific events discussed by the MFP, 3 please provide a very brief description of what went wrong 4 and what was done about it. Let's begin with the 5 Containment Fan Cooler Units Backdraft Dampers.

6 A60 (Giffin) Each of the DCPP units has five Containment 7 Fan Cooler Units ("CFCUs") within the containment to  ;

8 provide ventilation and cooling during normal operation as 9 well as postulated accident conditions. Each CFCU has a 10 backdraft damper downstream of the fan. The backdraft O

11 damper is designed to close on reverse air flow and 12 prevent the fans from rotating in a reverse direction. ,

13 The design basis accident reverse flow could be caused by 14 higher pressure in the discharge duct resulting from a t 15 postulated pipe rupture in the lower portion of the 16 containment structure.

O 17 The problems with the backdraft dampers discussed, 18 among other places, in NRC Inspection Report ("IR") 92-17, 19 involved loose counterweights on the dampers and the 20 incorrect assembly of certain linkages connecting the 21 damper vanes caused by inadequate maintenance practices.

22 PG&E identified and evaluated these problems and 23 determined that the CFCUs were operable in the as-found 24 condition. Accordingly, there was no safety significance 25 to the issue. The NRC found no programmatic deficiency or 26 breakdown in PG&E's maintenance program and did not take 27 any escalated enforcement action.

88 0 ,

i I O  !

l 1 Nonetheless, because the inadequate maintenance l

O 2- practices fell short of our expectations PG&E formed a HIT 3 team to assure adequate planning and coordination of 4 maintenance on CFCUs. Our investigations revealed several O 5 areas for improvement in the maintenance and surveillance 6 of the CFCUs, including improved procedures for damper 7 linkage servicing and tightening of damper counterweights, O 8 improved procedures for post-maintenance inspection and l

9 testing, improved training, and additional emphasis on 10 attention to detail when working on the plant ventilation 0 11 systems.

12 In addition, we increased system engineering support  ;

i 13 for this type of ventilation system and improved our D 14 efforts in performing thorough and probing investigations 15 of problems in ventilation systems. Later, as part of our 16 increased inspection efforts on this system, small cracks D 17 were found in some of the damper vanes. By the end of the 18 recent Unit 2 refueling outage, all of the damper vanes in 19 both units had been replaced with material which is less D 20 susceptible to initiation of fatigue cracks.

O ,

1 full-capacity Centrifugal Charging Pumps ("CCPs") to g 2 maintain water level in the reactor coolant system 3 pressurizer during normal operation. The CCPs have higher 4 flow capacity and are also used to inject water into the 5 primary system under certain postulated accident ,

z) 6 conditions. During normal operation, it is preferable to  ;

7 use the low flow PDP for charging. However, the industry 8 has experienced hydraulic / mechanical vibration problems O

9 with this type of high pressure, low flow reciprocating 10 pump for many years. At DCPP, the PDPs have required 11 relatively high maintenance, and vibrations under certain O

12 operating conditions have caused pipe cracking in some of i 13 the associated small diameter piping system. l g 14 In August 1990, the PDPs for both units were placed in  ;

15 standby service status pending installation of in-line 16 vibration dampening devices. In the interim, the CCPs are g 17 being used for this normal charging function in accordance 18 with plant operating procedures. ,

19 In August 1992, PG&E received two notices of violation 20 concerning the lack of appropriate procedures for O

21 operation of the PDPs as a backup to the CCPs in the i

22 unlikely event of a fire in the centrifugal charging pump 23 room. our own investigation concluded that there was a lO 24 weakness in our procedures for using the PDPs as a backup

?

25 under this postulated fire situation. However, neither 26 the NOVs nor our own evaluation found any deficiency _in g

l 15 Steam Generator Feedwater Nozzle Indications ,

i 3 16 Q62 Could you address the MFP reference to indications of l 17 steam generator feedwater nozzle cracks in Unit 1 in 1992?

r

[) 18 A62 (Crockett) The steam generator feedwater nozzle is a 19 20-inch diameter piping connection through which feedwater l

20 flows into each steam generator. These nozzles and the

[) 21 immediate upstream piping are susceptible to interior 22 surface cracking as found at other nuclear power plants.

23 This surface cracking results from nozzle metal 24 temperature difference caused by certain relatively 25 infrequent operating flow conditions during which cold 26 water is flowing into the steam generator through a hot 91

[)

t l

. 1

i f

)

1 nozzle. During a visit to another nuclear plant, a PG&E

} 2 engineer observed a problem the plant had with feedwater  !

3 nozzle cracking. When the engineer returned to DCPP, he 4 r commended that as a prudent measure, inspections for

] 5 similar cracking be performed at DCPP at the next 6 scheduled refueling outage. As a result, during the fifth 7 refueling outage for Unit 1, in September 1992, an 8 ultrasonic inspection was performed which indicated some 3

9 surface cracking indications in the steam generator 10 feedwater nozzle connection welds at DCPP.

j 11 Based on these findings, a short piping section and 12 the pipe-to-nozzle weld were replaced on all four steam 13 generators in DCPP Unit 1. Later metallurgical 3 14 investigations of the removed pipe and weld material, 15 using sophisticated detection techniques, determined that 16 the actual interior surface cracking was significantly 17 smaller than indicated by the original ultrasonic 3

18 evaluation. The ASME code allows such small surface 19 cracking and, thus, we could have actually continued 3, 20 operation without repair. Our crack growth projection  ;

i 21 calculations demonstrated that crack growth would not have 22 exceeded code allowables for at least another full cycle 3

j 23 of operation.

24 Surface crack depth was determined to have been 25 acceptable during the previous cycle operation, and 26 repairs were not required for safety or code compliance

, 27 reasons. Thus, there was no safety significance to this 28 issue.

92

l l

) u 1 Nonetheless, to minimize future potential problems in 2 this area, a design change is being developed to install a 3

3 thermal sleeve device inside the pipe and nozzle l 4 connection to prevent contact between cold feedwater and i j 5 the hot nozzle connection at this location during the ,

6 relatively infrequent operating conditions of high .

7 temperature differential. In retrospect, this is an 8 excellent example of the proper functioning of the DCPP 3

9 maintenance and surveillance program, especially in 10 assimilating industry experience and proactively i

g 11 initiating repairs even where existing standards do not i

12 require such repairs.  ;

13 Reactor Cavity Sump Level Indication 3

14 Q63 MFP has raised a question regarding alleged inadequate 15 corrective action involving the Reactor Cavity Sump Pump j 16 Level Indication system. Could you address this question?

h 17 A63 (Vosburg, Crockett) On November 6, 1990, it was f g 18 discovered that both Wide Range Reactor Cavity Sump Level 19 instrumentation channels were inoperable. Investigative 20 actions subsequently determined that the instruments had l 21 been inoperable since August 21st of that year. The cause 3

22 for the failure of one of the indicators was due to a .

23 blown fuse. However, due to the intermittent nature of  ;

24 the failure, our extensive investigation could not 7

, t 25 determine the exact cause for the failure of the other l i

93 l

I i

l l

\

1 channel. A suspect component was replaced and the ]

l )

[) 2 instrument was tested and returned to service.  ;

l 3 The delay in recognizing these failures was due to the j

, 4 fact that the instrumentation normally indicates zero q D 5 percent sump level and the indicators had " failed low", l l i l 6 thus giving approximately the same indication. Sump level j I

7 is also displayed on the Safety Parameter Display System j D 8 ("SPDS") which provides the plant operators with certain  ;

9 safety-related information. The SPDS provides an l l

10 indication when questionable input values are detected.  !

i D 11 As a corrective action for this event, training was given l-l 12 to operations and maintenance personnel on interpreting 13 the SPDS displays with respect to failed channel D 14 indications.

15 On October 22, 1991, another intermittent failure l

! 16 occurred in one of the two sump level indicators and l

D 17 investigation determined that the indicator had been out 18 of service for approximately eight days. Again, the root 19 cause for the instrument failure could not be found. After

[) 20 replacing the instrument and much of the interconnecting 21 cable, the problem was resolved. The sump level i 22 instrumentation has operated normally since that time.

i

) 23 Since the failed instrument had been inoperable for 24 approximately eight days prior to discovery, the 25 effectiveness of the initial corrective action was

) 26 reexamined. Additional corrective measures were taken to 27 revise STP I-1B, " Routine Daily Checks Required By 28 Licenses", to include a step for a member of the

) 94

O 1 Operations staff to check the SPDS display each shift.

() 2 The STP now includes specific guidance with respect to 3 SPDS indications of a questionable instrument channel and 4 actions to be taken when channel problems are identified.

3 5 As further corrective action, PG&E has reviewed all SPDS 6 and control room indicators where a similar instrument

! 7 failure might be difficult to detect from the control room

() 8 and improved the procedure to cover these additional 9 control room indicators.

10 This event is not indicative of a programmatic 0 11 breakdown in the maintenance program. In each case, 12 extensive investigative effort was expended to determine 13 the specific cause of the instrument failures. However, 14 in some cases involving intermittent failures it can be 7) 15 extremely difficult to pinpoint the exact cause for an

! 16 equipment failure. The most likely causes of the problem 17 are addressed, the equipment tested and/or replaced, and 9

18 returned to service under increased surveillance. In this l

l 19 case, the initial actions taken to improve the capability 1

20 to identify a degraded channel were not effective. When f

9 l 21 this was recognized, more comprehensive actions were taken 22 to replace the faulty equipment and assure that any 3 23 possible failures in the future would be promptly 24 detected.

O 1 Motor Operated valves 2 Q64 MFP has identified DCPP's response to Generic Letter 3

3 89-10, regarding motor operated valves, as being 4 deficient. Could you discuss this issue and DCPP's g 5 response?

6 A64 (Ortore) An extensive MOV testing program is being g 7 implemented throughout the industry in response to NRC 8 Generic Letter 89-10. In their supplemental Petition, MFP 9 refers to NRC Inspection Report 91-39, dated January 24, 1 1992, which identified certain weaknesses in PG&E's MOV O

11 testing program involving calculation methodology, 12 selection criteria, verification parameters and trending.

,0 13 MFP's reading of the inspection report is out of 14 context. Notably, the NRC inspection report in fact 15 concluded that PG&E appeared to be developing an g

16 " aggressive" and comprehensive Generic Letter 89-10 1

17 program. No deviations or violations of NRC requirements 18 were found. The NRC inspection report comments regarding

)

19 " weaknesses" are typical of NRC inspection activities in 20 areas of development and improvement. The inspection 21 report also commented that our MOV program was proceeding 3

22 satisfactorily. Their comments and concerns were 23 evaluated by PGLE and our program has been adjusted in

, 24 specific areas to make further improvements.

25 PG&E believes that it has a good MOV program. PG&E is 26 monitoring the development of the industry's response 96 g

S  ;

i j

l' through its participation on industry groups and

g. 2 committees. Again, nothing in the NRC IR cited by MFP i 3 supports the conclusion that this aspect of DCPP's j 4 maintenance and surveillance program is deficient. $

ti G l 5 Debris Found in Containment Buildinc 6 Q65 MFP has stated that DCPP had a problem with debris in t

g 7 the containment building. Could you discuss this issue?

i 8 A65 (Crockett) The RHR recirculation sump in each 3 9 containment building provides a collection point for water {;

10 during a postulated accident, so that the water can be i 11 recirculated, cooled and returned to the system for g 12 accident mitigation. Housekeeping inside the containment.

13 building should assure that no loose debris (rags, papers,  ;

i 14 clothing, plastics, etc.) can be transported to the ,

15 containment sump.

3  ;

16 In October 1991, near the end of the Unit 2 fourth 17 refueling outage, certain debris was found in the f 18 containment building during a PG&E Quality Control 3 ,

19 surveillance. The debris included a small plastic bag, 20 some wipealls, a tool bag, a_ water jug and a tool bin. An l

)< 21 engineering evaluation demonstrated that this small amount 22 of debris would not have impreted the operability of the- ,

23 safety systems and, therefore, it did not represent a j g 24 safety concern. Later, during the Unit 1 fifth refueling 25 outage, although there was overall improvement, some  !

26 further problems with control of debris were noted. l 97 3

O' i

1 These problems with control of debris in the .;

() 2 containment building caused PG&E to recognize that the  ;

3 program in effect to control material and housekeeping in  ;

t 4 containment during outages needed to be reorganized and. [

O 5 strengthened to clarify responsibility for housekeeping 6 and control of loose debris. f I

7 Corrective action Las included the logging of i

() 8 all personnel in and out of containment at key times, f

9 logging and inspection of all jobs in progress every .

10 shift, periodic containment walkdowns, and a  ;

+

C) 11 documented tailboard explaining the importance of 12 housekeeping rules for all workers allowed in containment.  :

i 13 The containment coordinator is now responsible for ,

() 14 performing a housekeeping inspection of the accessible-15 work areas of the containment during each shift to verify-16 naintenance of housekeeping standards. PG&E believes that l

() 17 these corrective actions will prevent recurrence.

L 18 Diesel Generator Turbo Charcer Bellows Boltina f

() , 19 Q66 Could you discuss the problem with DCPP's expansion 20 bellows during pre-operational installation of the new 21 sixth emergency diesel generator? ,

O  ;

22 A66 (Vosburg) An expansion bellows is used on the turbo l

23 charger for each emergency diesel generator to connect the

() 24 turbo charger to the exhaust piping. The issue cited by l i

25 MFP and addressed in NRC IR 92-14 (June 5, 1992) involved 1 26 insufficient written instructions for installing the lower O 98

O l' flange connecting the expansion bellows to the turbo 2 charger during pre-startup installation of the new sixth 3 diesel generator. The installation engineer verified the 4 correct bolting and gasket material to be used, and the 5 installation was completed. However, this action was not 6 documented in accordance with DCPP procedures. Because 7 the work was completed properly, the documentation 8 deficiency had no safety significance.

9 This issue was not a maintenance or surveillance 10 problem. It occurred during the installation of the new 11 sixth diesel generator during the construction phase. At 12 the time, the sixth diesel generator had not been turned 13 over to the plant, and was not yet part of the plant's 14 safety systems. The deficiency in documentation was 15 corrected and the level of attention to such documentation 16 was improved on the sixth diesel generator project.

O 17 Diesel Generator Fuel Oil Pipinc Corrosion 18 Q67 Could you discuss the corrosion problem discovered by 19 PG&E involving the diesel generator fuel piping?

20 A67 (Crockett) The diesel generator fuel oil system is 21 used to transfer fuel oil from underground storage tanks 22 to the emergency diesel generators. This small diameter 23 piping runs below ground in concrete trenches, on the 24 seaward side of the turbine building and within the 25 turbine building buttress area. The piping was installed 26 in the 1970s and has experienced corrosion on its external 99 0

=

)

i l

1 surfaces from the salt air environment. Over time, this  ;

l h 2 environment corroded the piping's exterior surface in 3 areas where the external coating on the piping had not 4 been fully effective in preventing corrosion.

3 5 This problem, identified by PG&E in voluntary Licensee 6 Event Report 1-92-006, was discovered during a PG&E >

7 inspection. Certain local repairs were made in the highly

) 8 corroded areas. PG&E determined that the system's r 9 operability was not compromised even in the degraded s 10 condition. However, based on the general conditions of h) 11 the piping and the environment in the trench area, it has >

l 12 been decided to replace the entire length of piping and to '

i 13 use improved coating techniques in the new installation.

21 14 Accordingly, this issue - identified and corrected by 15 PG&E - does nothing to support MFP's contention. This l

16 type of problem and its resolution illustrates how the i

) 17 DCPP maintenance and surveillance program functioned 18 properly to find the deteriorating piping and then to 19 replace the piping with upgraded design materials or 3 20 construction techniques.

6 In June 1992, during a routine radiation survey, .

7 leakage was noted from a CVCS valve bonnet in a ,

O 8 heat-traced portion of the system. This leakage was 9 determined to be outside the design basis for CVCS 10 leakage. The leak was immediately stopped by tightening

() 11 the valve body-to-bonnet nuts. The issue was identified ,

12 by PG&E and reported in LER 1-92-009, Revision 1, dated 13 January 11, 1993.

() 14 Our investigation revealed that the cause of the 15 leakage was thermal degradation of the valve diaphragm due i 16 to a malfunctioning heat trace thermostat causing leakage I

O 17 through the body-to-bonnet joint. Corrective actions 18 included lowering the heat trace temperature for the 19 valve, reviewing every other valve in similar service in O 20 Units 1 and 2 to verify there were no other potential 21 problems, reviewing the entire heat trace system for 22 proper setpoints and installation, and improving our i

O 23 surveillance monitoring program.

24 A similar leak occurred in September 1991 due to a

O 10 A69 (Giffin) An NRC inspection during February 1991 found 11 deficiencies in the control of Measuring and Test 3 12 Equipment ("M&TE") administrated by the Mechanical .

i 13 Maintenance ("MM") Department at DCPP. This inspection i

14 also found that PG&E's own Quality Control ("QC") and ,

g 15 Quality Assurance ("QA") Departments had previously 16 audited the MM M&TE program and found similar deficiencies 17 which had not been aggressively corrected. i g 18 The identified deficiencies were reviewed in detail to 19 det' ermine the potential impact on plant equipment. The 20 deficiencies involved calibration or use of torque 3 21 wrenches and nechanical gauging devices. The application l

l 22 of the torque wrenches and gauging devices was found to .

6 for MM M&TE equipment to the Instrument and 2cntrols (1&C)  :

7 Department M&TE program -- a program which was, and is,

l l 10 information on the deficiencies found by PG&E's QC O 11 organization, but had not yet implemented improvement in a l

f 12 timely manner. Additional corrective action included i

13 improvement in the quality resolution process, better O 14 definition of management expectations concerning the 4

1 of this inspection. The specific " weaknesses" which were g 2 described on page 1 of this NRC report and discussed by 3 MFP were attributed by the NRC to the Engineering 4 Department. These weaknesses were not relevant to DCPP's 5 naintenance and surveillance programs. Two Severity Level O

6 IV NOVs were issued but they were separate and apart from 7 the NRC " weaknesses" discussed by MFP. Both NOVs related 8 to specific surveillance procedures which have been

.J l

l l

17 A71 (Crockett) The Fuel Handling Building ("FHB")

3, 18 ventilation system for each unit is designed to maintain a 19 slight negative pressure inside the building. This design 20 is accomplished by removing more air (with the exhaust 21 fans) than what is supplied to the FHB (by the supply  ;

c) 22 fan). Thus, air leakages will be inward and all potential 23 releases from the spent fuel pool are exhausted through l

)

, 24 filters. This functional capability is required to be j

)

I fully met the specific requirements for negative O 2 pressures. The next required test was performed on 3 January 18, 1992. Although the measured pressure was 4 negative, it did not meet the specific operability 0 5 requirement. PG&E conservatively assumed that the FHB 6 ventilation system was inoperable at the time of fuel 7 movement during the Unit 1 third refueling outage in O 8 October 1989. Prompt action was initiated in accordance 9 with our problem resolution procedure to investigate the 10 situation, determine a root cause and implement corrective O 11 action.

12 Our investigation determined that the cause of system 13 inoperability was the existence of small leakage paths 0 14 into the building due to building and seal degradation.

15 Corrective action included sealing the leaks. Both FHBs 16 have also been re-sided. The new siding is the best b 17 available on tne market with an expected life of greater 18 than 25 years.

19 Analysis of the event showed that because of 20 conservatism in the ventilation system design, sufficient 21 negative pressure was maintained at the surface of the 22 spent fuel pool throughout the event and there was no O 23 safety significance.

24 RHR Recirculation Sump Screens O 25 Q72 MFP has stated that DCPP had a problem with gaps in 26 the containment building recirculation sump screens and 27 debris inside the sumps. Could you discuss these issues?

p 105

)

1 A72 (Crockett) Yes. RHR recirculation sumps are

) 2 surrounded by debris screens. In February 1990, the NRC 3 issued Enforcement Action 89-241 citing PG&E for three 4 violations related to the RHR recirculation sump screens.

) S One of the violations involved inadequate engineering and 6 construction completion, which resulted in unacceptable 7 gaps in the screen structure. The second involved

) 8 operational control that allowed an unattended open access 9 hatch in the screens. Neither of these two violations 10 bears any relation to maintenance or surveillance. Both

) 11 were corrected. The third violation included a reference 12 to poor performance of a visual surveillance of the sumps, 13 which resulted in unidentified debris remaining in the

) 14 sumps. This deficiency was an isolated personnel error --

15 an individual failed to implement an otherwise clear 16 procedure. This does not indicate a program problem. As

) 17 a corrective action, PG&E clarified requirements for 18 inspection of the sumps.

) 19 Turbine Governor and Stop Valve Malfunction 20 Q73 Describe the DCPP turbine governor and stop valve 21 malfunction cited by MFP.

J

)

22 A73 (Vosburg) The main turbine speed is controlled by four 23 governor valves ("GVs") during startup, operation and  ;

1

) 24 shutdown. Four additional stop valves ("SVs"), located in 25 line with the GVs, are used to trip and isolate the 26 turbine during overspeed and other conditions. All cight

) 106

D 1 valves are controlled by an electro-hydraulic ("EH")

3 2 system.

3 In September 1992 during a Unit 1 shutdown, 4 simultaneous circumstances occurred which resulted in a 3 5 steam flow path being created through the SVs and GVs 6 after the turbine had been tripped, thereby causing the 7 turbine to accelerate. The operators controlling the l 3 8 evolution immediately tripped the turbine. No reactor or t

9 turbine limits were exceeded.

10 Our investigation into this event found the cause to ,

3 11 be a combination of factors, including a sticking pressure j 12 switch, low EH system pressure and steam leakage. ,

4 13 Corrective actions included replacing and upgrading the 3 14 pressure switch, correcting several conditions in the EH 15 system and revising our shutdown procedures to add 16 additional verification of EH system control parameters 3 17 during turbine shutdown.  ;

18 Two other previous related events merit discussion. i 19 In August 1991, a problem with the Unit 2 turbine control 3 20 system resulted in a spurious GV opening. Rigorous j 21 investigative testing could not determine the root cause. {

22 The problem was intermittent and could not be reproduced. {

3 23 The most likely cause was thought to be a sticking  ?

24 pressure switch, similar to the switch which contributed i 25 to the September 1992 Unit 1 event. The switch was

i 27 on Unit 1 due to suspected steam leakage. The SVs were  ;

1 operable and, therefore, no corrective action was D 2 necessary.

3 PG&E believes tPV its investigation and corrective 4 actions for these two events were comprehensive and D 5 thorough. In retrospect, operations personnel should have 6 implemented more positive interim compensatory action 7 (such as changes to the operating procedure or additional D 8 training) which may have prevented the third, September 9 1992, event. As part of our corrective action for the 10 third event we upgraded our use of interim compensatory D 11 measures.

12 No operating limits were exceeded during any of the 13 three events. This equipment is not safety-related. None D 14 of the events was safety significant.

15 4kV/12kV Cable Problems D 16 Q74 MFP has raised an issue regarding maintenance of the 17 4kV and 12kV underground cables between the turbino 18 building and the intake structure. Please discuss the D 19 recent problems experienced by DCPP involving these 20 cables.

D 21 A74 (Ortore) DCPP has experienced three failures of 4kV 22 cables -- two safety-related and one nonsafety-related.

23 Two of these failures were random in nature and time of 24 occurrence. One of the failures was detected by PG&E 3

25 during post-maintenance High-Potential ("Hi-Pot") testing.

26 Additionally, there were two area-specific failures of D 108

)

1 non-safety 12kV cables. Both types of cable are contained

}

2 in conduits located in underground duct banks routed 3 between the turbine building and the intake structure.

4 The safety-related and non-safety related 4kV cables i

5 supply electrical power to safety related cooling water i 3

E pumps and a non-safety related load center transformer, 7 respectively. The nonsafety-related 12kV cables supply 8 electrical power to the main circulating water pumps.

3 &

9 The failures which occurred in the 12kV 10 nonsafety-related cables were caused by exposure to a j 11 contaminant which was present in the underground conduits 12 in a localized area between the turbine building and the i

13 intake structure and which caused severe cable jacket and 14 insulation degradation. Both of these failures were 3

15 detected with the ground detection system, allowing ,

16 operator action to isolate the cable before complete 17 failure of the cable.

3 18 Neither of the two safety-related 4kV cable problems i 19 involved actual in-service failures. One involved a j 20 momentary alarm indication signaling a potential ground 21 fault. When this occurred, the redundant cooling water 22 pump was started and the cable with the potential fault 23 was isolated. The second case occurred during routine 3

24 "Hi-Pot" testing while the cable was out of service during 25 a refueling outage. One of the two safety-related 4kV 26 cables was in a location remote from the more recent 12kV ,

7 27 cable failures. Moreover, the 4kV cable jackets did not i 23 exhibit any physical degradation as did the 12kV cable

) 109 i__.____.___.______._ _ _ _ -_ _ _ .

O 1 jacket. These differences would suggest that there was no g 2 imminent common-mode cable failure mechanism involved with 3 these occurrences .

4 After failures occurred to the 4kV and 12kV cables, 5 the failed cable sections were replaced. Reviews of the 6 original design, installation, quality assurance and/or 7 quality control audits for the failed cables were 3

8 conducted. These reviews have concluded that the installed 9 cables are of acceptable quality and design for the'ir 10 specific applications and service conditions (wet or dry).

11 However, as a prudent measure, additional sections of 3

12 unfailed 4kV and 12kV cables have been replaced.

13 A contributory cause of the 12kV failures was believed 14 to be water carrying contaminants into the cable conduits.

3 15 While sump pumps are provided in the vaults, they were not 16 at that time part of the formal maintenance program and, 17 accordingly, were not maintained in an adequate manner.

g 18 After rains, the vaults would fill with water and flood 19 the conduits. The sump pumps have been repaired and are 20 now included in our preventive maintenance program.

3 21 PG&E believes that the maintenance activities with 22 regard to these underground cables are adequate, 23 particularly given the installations involved. To the g

24 extent our continuing analysis of these issues suggests 25 the need for further naintenance activities, they will be

, 26 included in our program.

The loss of RHR occurred during mid-loop ,

7 operating conditions. The causes of this -

D 8 event were related to inadequate control of 9 system operation during this infrequent and 10 abnormal operating condition. The event 3 11 resulted in extensive investigative and 12 corrective action. The enforcement action 13 cited deficiencies in the operating procedure

i 5 resources to address issues, we consider safety

! 6 significance, operational necessity, and the time it takes 7 to perform a comprehensive assessment of the issue. For 8 the kinds of issues identified by MFP, we believe that I

9 thorough investigation and thoughtful corrective action j 10 are very important aspects. We also believe that we have ,

11 emphasized the need for thorough responses, and that the 12 extensiveness of our corrective actions reflects our  ;

I j 15 Q77 Do these issues of events indicate a programmatic 16 deficiency or breakdown in PGEE's maintenance and 17 surveillance programs at DCPP? Why or why not?

\

)

  • 18 A77 (Giffin) No. The issues or events described above do ,

19 not in any way represent a programmatic deficiency or j 20 programmatic breakdown in PG&E's maintenance and 21 surveillance programs at DCPP. These issues or events i

22 represent a relatively few random and isolated occurrences

) 23 that are inevitable in any large and complex program of 24 human activities. They are not concentrated in any one l 25 aspect of the program. Rather, they have involved

} 113

1 different equipment, systems, procedures, locations, or

} 2 operating conditions. Furthermore, they have occurred at 3 random times and in a random manner, without a particular 4 pattern relating to organization staffing or supervision.

). 5 Moreover, I want to re-emphasize that the 6 maintenance-related problems that have occurred at DCPP 7 represent only a small number of occurrences relative to

) 8 the very large number of maintenance activities, 9 surveillances, and individua' steps in maintenance work  ;

10 orders. We perform more than a million individual ,

19 A78 (Giffin) Yes. Based on information provided to MFP by ;

I 20 PG&E during discovery in this case, MFP has identified l i

)

l 21 other documents which it intends to rely upon in this j t

22 proceeding. Some of these relate to plant maintenance and j l

23 surveillance activities.

r 24 Q79 How would you characterize these documents? l 4

l ll

O 1 A79 (Giffin) These documents generally are part of our normal 2 processes. As we have discussed elsewhere in this 3 testimony, when issues or problems are identified at the 4 plant, they are documented and thoroughly investigated to 5 prevent recurrence. A process is in place to track these 6 matters to resolution. We believe that a program of 7 aggressively finding and documenting problems, thoroughly 8 investigating them, and continually improving our 9 operations is essential to a complete and comprehensive 10 approach to plant maintenance.

11 In addition, as a means to foster continuous 0

12 improvement, we do perform from time to time candid self 13 assessments of our programs. In this context, the 14 existence of deficiency reports, critical

.O 15 self-assessments, and the like are not evidence of a 16 faulty maintenance program. Rather, they evidence a 17 properly functioning program.

13 TESTIMONY OF TEDD A. DILLARD ON BEHALF OF

'g 14 PACIFIC GAS AND ELECTRIC COMPANY 15 ADDRESSING CONTENTION I: MAINTENANCE AND SURVEILLANCE 16 Q1 Please state your name, affiliation, and current g 17 job responsibilities.

18 Al My name is Tedd Dillard. I am the Supervisor of 19 Component Programs for the Nuclear Division of Florida O

20 Power & Light Company ("FPL"). I was the Manager of 21 Maintenance at the St. Lucie Nuclear Power Plant from 22 May 1983 until November 1988. Prior to that, I was the

-() ,

23 Mechanical Maintenance department head at St. Lucie for j 24 eight years. My current responsibilities include  ;

-g 25 supervising the efforts of a group of engineers i

26 responsible for the FPL Nuclear Division's technical r

27 expertise for major plant components at both FPL

g 28 nuclear facilities. I am also responsible for 29 developing FPL's implementation plan for the l l

l 30 Maintenance Rule, 10 CFR 50.65.  !

116 O

O 1 Q2 What other qualifications do you have in the area O 2 of nuclear power plant maintenance?

3 A2 In addition to my maintenance experience at FPL, I O 4 have had an opportunity during the past six years to 5 visit a number of nuclear power plants and participate 6 in several industry maintenance assessment efforts. I O 7 was corporate evaluator on an Institute of Nuclear 8 Power Operations ("INPO") maintenance assistance review 9 team evaluation of our Turkey Point Plant. I was a 0 10 peer evaluator on an INPO maintenance assistance review 11 team at the Ft. Calhoun Nuclear Plant. I was a member 12 of one of several teams who visited the Mihama Nuclear O 13 Plant of Kansai Electric Company in Japan in 14 conjunction with our quality improvement efforts. I 15 served on the Nuclear Management and Resources Council O 16 ("NUMARC") Ad Hoc Committee that developed the industry 17 response to the proposed Nuclear Regulatory Commission 18 ("NRC") Maintenance Rule. I also served on one of four O 19 committees that developed the implementation guidance 20 document for NUMARC that the NRC has endorsed with the 21 regulatory guide for the NRC Maintenance Rule.

O 22 I have more than 23 years of experience in United 23 States commercial nuclear power plants, the last 20 of 24 which has been with FPL.

O 25 A copy of my professional qualifications is 26 provided in Exhibit 12.

O 117

9 1 Q3 What contention will you address?

O 2 A3 I will address San Luis Obispo Mothers for Peace 3 ("MFP") Contention I, which is:

g 4 "The San Luis Obispo Mothers for Peace contends 5 that Pacific Gas & Electric Company's (PG&E) 6 proposal to extend the life of the Diablo Canyon 7 Nuclear Power Plant for more than 13 years (Unit 8 1) and almost 15 years (Unit 2) should be denied 9 because PG&E lacks a sufficiently effective and g 10 comprehensive surveillance and maintenance 11 program."

12 Q4 What is the purpose of your testimony?

O 13 A4 The purpose of my testimony is to provide my 14 opinion as to whether PG&E has implemented a C 15 comprehensive and effective maintenance program at the 16 Diablo Canyon Nuclear Power Plant ("Diablo Canyon").

17 PG&E specifically requested that I visit Diablo Canyon O

18 and review the maintenance program, procedures, and 19 program implementation at the plant in light of my 20 experience with maintenance at St. Lucie and in O 21 observing and evaluating other nuclear power plants.

22 It is my understanding that PG&E solicited my views, in 23 part, based on the fact that St. Lucie has been given O

24 Category 1 ratings by the NRC in the maintenance area 25 in Systematic Assessment of Licensee Performance 26 ("SALP") evaluations. St. Lucie is also one of the O

27 plants singled out by the NRC for distinction on its 28 "Best Plants" list.

9 118 i

D 1 Q5 What were your overall impressions of the Diablo 3 2 Canyon maintenance program?

3 AS Based on my review of the program and procedures, 3 4 my interviews with maintenance personnel, and my visit 5 to the plant, it appears to me that PG&E has 6 implemented a comprehensive and effective program. I 7 observed no significant weaknesses. In the time 3

8 available to me, I did not, of course, review all 9 details of the program. However, I should add also --

10 and I will spell this out in more detail below -- that 3

11 based on my experience, I believe I can spot quite 12 readily a well-maintained plant or a poorly-maintained 13 plant based on some important indicators. Diablo 3

14 Canyon appeared to me to be very well maintained by a 15 very professional and knowledgeable staff.

D 16 Q6 In general, explain the criteria you applied in 17 evaluating Diablo Canyon.

D 18 A6 I will use as a guide the elements contained in 19 INPO Document 90-008, Maintenance Proarams in the

'20 Nuclear Power Industry. This document is a compilation

]

21 of the performance objectives and criteria used by INPO 22 in evaluating nuclear power plants. I believe that the 7 23 objectives and criteria are comprehensive and that if 24 an organization effectively implements them the 25 resulting performance will be good, and more 119 3-

O ,

}

1 importantly, will continue to improve over time. Like O 2 many plants, Diablo Canyon has a maintenance program 3 that meets the elements contained in INPO 90-008. I ,

4 would like to point out that INPO 90-008 is not an O 5 organization chart or structure, but is a list, in no 6 particular order, of elements or functions of F 7 maintenance that have been shown to be important to the ,

i

-O 8 effective operation of a nuclear power plant.  :

9 I note also that in one of the prehearing 10 conference orders in this case, the Licensing Board t

O 11 observed that the existence of adequate programs on  ;

t 12 paper does not constitute proof of effectiveness, but  ;

13 that "the implementation of these programs is the only O 14 real gauge of their effectiveness." Given my operating 15 background, I could not agree more. When I look at a 16 plant, Diablo Canyon included, I specifically look at -i O 17 how paper programs are implemented. r I

18 In addition to an overview of the programs in i

19 place at Diablo Canyon, I have, therefore, tried to O_ 20 make specific personal observations at the plant. It 21 is not the purpose of my testimony to respond in detail f 1

22 to any of the specific examples cited by MFP in the j l

O 23 bases for their contention. However, I have tried to l l

24 use observations closely related to their examples.  ;

25 The):e are thirty INPO elements, but I am addressing the Cf 26 eignteen that I believe are most relevant to the l

27 cortention.

O 120

) 1 l

l 1 Q7 Please address your criteria one-by-one and [

2 provide your observations regarding Diablo Canyon. The ,

3 first concerns Management Assessment.

l 4 A7

  • Manacement Assessnent 5 Performance Objective: Management and 6 supervisory personnel should monitor and 7 assess station activities to improve all 8 aspects of station performance.

9 Criteria: Line managers and supervisors are 10 responsible for and personally take part in 11 monitoring and assessing station activities.

12 Assessments by other independent groups, such 13 as Quality Assurance, are used by line

'. 14 managers and supervisors as a management tool

, 15 to assist them in assessing station 16 performance.

17 It is my observati~on that this element of the l

18 program is in place. Specific examples are:

I 19

  • The housekeeping throughout the plant was i

I f 20 excellent.

j 21

  • There were only about twenty action tags hanging 22 on equipment in the secondary part of the plant.

23

  • The condition of both operating'and standby l

i 24 equipment was very good. ,

25

  • Compliance with industrial safety work practices 26 was excellent. Everywhere I went people wore 27 their hard hats, eye glasses, and hearing

! 28 protectors. ,

29

  • People were careful to ensure that fire and l

30 security doors locked properly behind them.

31

  • Supervisors and managers that I talked to were  ;

32 readily able to discuss the condition of 121

)

J h

1 equipment, and were very responsive to questions O 2 about the trends in performance and condition in i 3 their area.

4 It is my conclusion that the conditions that I O 5 have listed (and there are many more) would not be true 6 unless the managers and supervisors are doing an 7 excellent job in assessing plant conditions.

p l

8 QB The next criterion is Quality Programs. Please l 9 describe your observations in this area.

O 1

10 A8

  • Ouality Proarams 11 Performance objective: Quality programs

! 12 should effectively monitor activities that O 13 affect safe and reliable plant operation, 14 provide feedback to line management on 15 quality of performance, and contribute to 16 improved performance. ,

l 17 Criteria: Quality programs reinforce and ,

O 18 support the line functions of managers and 19 supervisors. Line managers and supervisors .

20 are responsible for and held accountable for i 21 the quality of work performed within their 22 area of responsibility.

O. 23 There were a number of indications that quality

, 24 programs are healthy at Diablo Canyon. Some examples l

l 25 follow:  :

i

26

) 29 Program," dated June 30, 1992, generated at a very 30 high level in the organization. This shows a 31 strong commitment to the issue. This is being i D 122 l l

t

i .

'O l

i l

l 1 addressed as a high level business objective. It O 2 is a very comprehensive document and includes all i

3 aspects of plant aging. It addresses how to 4 define terms and how to apply the programs. It O 5 discusses different age-related degradations and '

l 6 mechanisms. But most importantly, it outlines the l

7 relationship of the many activities, ,

f) 8 organizations, and outside factors that bear on 9 the issue. It also assigns responsibility for the i

10 implementation. I believe this document indicates O 11 that PG&E is clearly aware of the importance of 12 managing this issue and has taken action to do so.

13

  • Examples of quality programs in place that I O 14 observed are:

15 -

Hot work permits 16 -

Equipment clearance tagging I) 17 -

Scaffold tagging 18 These examples demonstrate that quality programs 19 are in place and are working. ,

<O 20 Q9 The next criterion is Maintenance Organization and q 21 Administration. Please address this.

b 22 A9 e Maintenance Orcanization and Administration I 23 Performance Objective: The maintenance 24 organization and administration should ensure

<) 25 effective implementation and control of 26 maintenance activities.

[ 27 Criteria: Administrative controls are 28 employed in the conduct of maintenance O 123

I O

l 1 activities that affect safe and reliable 2 plant operation. Examples of such activities O 3 include scheduling of preventive maintenance, 4 use of special tools and lifting equipment, 5 and use of measuring and test equipment.

6 In my tour of the plant and discussions with plant )

O 7 staff, it was clear that the maintenance organization 8 and administration are being effectively implemented.

9 Observations are:  !

O 10 . In all discussions with plant staff, they had a 11 ready answer for who was responsible for various 12 aspects of what was being discussed. For example, ;

O 13 when talking to technical support people about the I 14 Inservice Testing ("IST") program, they had a 15 clear understanding of how the check valve O 16 inspection program in maintenance fits in.

17

  • The Work Planning Department plans and coordinates -

18 the work of all three maintenance disciplines with O 19 the Operations Department. This is a free-20 standing organization that must effectively -

21 coordinate the activities of many different O 22 departments. They are responsible for daily work  !

23 and outage activities, too. The efficient outages l 24 that Diablo Canyon has had show how effectir' PG&E O 25 has been, as this is a major effort coordinating 7 26 several thousand activities in a sixty-day period.

j 27

  • Significant work has been done at the intake ,

28 structure over the past couple years. The scope l 29 and volume of this work was substantial and 30 required a coordinated effort from many groups to 124

O i i I

1 be successful. The success of the improvements in i c

O 2 the intake structure is an excellent example of t 3 organizational effectiveness.

4

  • An interdepartmental administrative procedure was

=

O 5 developed to improve the implementation of the '

i' 6 plant's response to Generic Letter ("GL") 89-10 i 7 regarding motor-operated valves ("MOVs"). This 50 8 document outlines the actions and accountabilities 9 of eight different plant organizations that play a 10 role in effectively responding to the requirements ,

O 11 of GL 89-10. The NRC noted in their inspection of 12 this area that "the inspection findings indicated t

13 that you appear to be developing an aggressive, o

0 14 well-integrated program for assuring MOV 15 reliability. Program strengths were found in the 16 area of program scope and your high impact team t

C) (HIT) approach to integrating the 17 18 multi-disciplined activities required for the 19 89-10 program." f O 20 These examples show, in my opinion, that the l 21 maintenance organization is properly defined and that i

22 proper administrative controls are in place. From what ;

O 23 I have seen, the organization appears to be effective. ,

24 Q10 Next, please address the Plant Material Condition 25 at Diablo Canyon.

26 A10 e Plant Material Condition 0 125 1

1 Performance Objective: The material G 2 condition of the plant is maintained to 3 support safe and reliable plant operation.

4 Criteria:

5 -

Systems and equipment are in good 9 6 working order; examples of this include 7 the following:

8 a. Fluid system leaks are minimized.

9 b. Equipment is appropriately 10 protected from adverse

  1. 11 environmental conditions.

12 c. Instruments, controls, and 13 associated indicators are 14 calibrated, as required.

15 d. Good lubrication practices are 16 evident.

O 17 e. Fasteners and supports are properly 18 installed.

19 f. Equipment, structures, and systems 20 are properly preserved and 21 insulated.

O 22 -

Material deficiencies are identified and 23 are in the work control system.

24 -

Temporary repairs are minimized and 25 permanent requires are made when 26 conditions permit.

27 -

Temporary environmental protection D 28 (e.g., dust, humidity, freeze, shock) is 29 provided for plant equipment when needed 30 to support construction, outage, or 31 maintenance activities.

32 -

Newly installed or modified 33 systems / equipment are verified to be in O 34 good working order prior to operational 35 acceptance by the plant staff.

36 Plant material condition is one of most visible 37 examples of maintenance effectiveness. The condition 38 of the equipment is the end to which all programs and 39 efforts point. While visual appearance alone is not a 40 guarantee of reliability, it is a very good indicator 41 of equipment condition. Diablo Canyon has an excellent i

3 126 i

lO I plant material condition. Some of the many examples g 2 are noted below:

3 e I toured two of the six emergency diesel generator l 4 rooms. The rooms were very clean with no dust or 5 trash anywhere. There were no equipment or tools l0 6 left anywhere in either of the rooms. There were -

I 7 only two action request tags hanging in both 8 spa es. The air start air supply system was very

.O ,

9 leak-tight as the compressors never cycled in the 10 ten minutes we were in the rooms.

11

  • The 4kV switch gear rooms were in excellent

)

12 condition. There were no cross-under pipe manway 13 cover leaks. It h'as been my experience that they ,

14 are next to impossible to consistently make up g

15 leak tight.

16

  • The piping rack area, which includes the auxiliary 17 feedwater ("AFW") piping, was in very good g

18 condition. The valves, pipe hangers and pipe 19 snubbers were all in good condition. f 20

  • The feedwater heater level control stations were O i 21 in excellent shape. They were_ leak-free, clean, 22 the lights behind the level site glasses were lit 23 and were in about as good a condition as any I g t 24 have ever seen. It has been my experience that the 25 level site glasses are difficult to prevent from l

26 leaking. The insulation on the feedwater heaters

)

27 was very clean and neat.

f ,

127 g

l 0  :

I i

1

  • The main feedwater pump and drive turbines were in O 2 very good shape. These types of turbines have a [

3 low pressure control oil system and usually have a  ;

4 number of small leaks on the reservoir and bearing l i

O 5 pedestals, in my experience. Tnese particular  ;

6 ones were very clean and dry. The turbine l 7 platforms were clean and free of any debris. I O 8

  • The condensate pumps, the condensate booster  !

9 pumps, and the heater drain pumps were all clean l 10 and leak-free.

O 11

  • oiablo canyon uses a large vacuum pump to draw 12 vacuum and a stream jet to maintain vacuum, so the 13 pump is in standby mode most of the time. It was  ;

F O 14 in excellent condition.

15

  • The condenser wells were in very good condition l f

16 with no evidence of leaks down in the well area.

O 17 The wells were very clean. There were no  ;

18 materials or tools stored down in the wells.  !

19

  • The intake area, both top-side where the screen j

)

O, 20 drives are and below where the pumps and motors 21 are, was in excellent condition. This area has  !

I 22 had a large effort directed at improving its j O 23 condition in the last year. Large areas of 24 concrete have been chipped out and replaced. They i

25 are about complete with this effort and the ,

O 26 results are outstanding.  !

The intake screens are being replaced with new i 27

  • 28 stainless steel all welded units.

O 128

D ,

1 There are many other specific observations I could O 2 make but I believe the examples provided demonstrate 3 that the equipment at Diablo Canyon is in very good 4 condition. This is one of the very best plants that I O 5 have seen. There is no doubt is my mind that a plant 6 could not be kept in this condition and not have an 7 effective maintenance program.

O 8 Q11 What were your observations regarding the Work  !

9 Control System? l 1

O i 10 All

  • Work Control System 11 Performance Objective: The control of 12 maintenance work should support the O 13 completion of tasks in a safe, timely, and i 14 efficient manner such that safe and reliable 15 plant operation is optimized.

16 Criteria: ,

C) 17 -

The work control system provides 18 management with an accurate status of 19 maintenance planning and outstanding 20 maintenance work.

21 -

Work planning includes considerations a C) 22 such as material, tool, and manpower ,

23 requirements; interdepartmental 24 coordination; safety considerations; f l

25 radiological protection requirements; 26 and quality control requirements. i i 27 Maintenance history records and NPRDS j C) 28 information are considered where 29 appropriate.

30 -

Advance planning is performed and -

31 routinely updated for scheduled outages.

32 Considerations such as work priority,

) 33 work procedures and instructions, 34 plant / system conditions, length of 35 outage required, prestaging of documents 36 and material, and coordination of 37 support activities are included.

129 l

O 1 Some of my observations follow:

O 2

  • Diablo Canyon has a work planning department that 3 has the responsibility of planning all of the work 4 done by the Maintenance Department and scheduling O 5 all of the work performed on site. They do this 6 on a daily basis as well as for outages. Every 7 morning they meet with the representatives of all O 8 operating departments to go over the schedule for 9 the next few days. They meet on Friday afternoon 10 to review the plan for the weekend and again on 0 11 Tuesday to factor in what happened over the 12 weekend. This process is very tightly controlled 13 as a great effort is given to coordinate all the 0 14 activities necessary to accomplish a given job.

15 Jobs brought in late to this process must be 16 important in order to be included. The effort put

() 17 into the efficient planning and ccheduling pays 18 off in reduced manhours and equipment out of 19 service time. To do it well is the mark of a 0 20 strong organization, in my opinion, as it is 71 difficult to bring all different groups and 22 activities together on the dozens of jobs that are O 23 done on any given day.

24

  • The maintenance action requests ("ARs") are part 25 of the maintenance equipment history, and the

,0 26 number and age of action requests are tracked by 27 department. The division directors are O 130

4:

1 1 responsible for the control of the backlog and age

) 2 of the action request in their areas.

3

  • The excellent overall housekeeping condition of 4 the plant is an indicator of an effective work '

5 control system.

6

  • The posting of hot work permits, equipment ,

7 clearances, and scaffold tags are also indications 8 of an effective work control system.

9 I believe that these examples show that the work 10 control system at Diablo Canyon is well conceived.

?

11 Q12 Please address the Conduct of Maintenance at 12 Diablo Canyon.

)

13 A12

  • Conduct of Maintenance 1 r 14 Performance Objective: Maintenance should be j 15 conducted in a safe and efficient manner to 16 support plant operation. ,

17 Criteria: i 18 -

Personnel exhibit professionalism and j) 19 competency in performing. assigned tasks that 20 results in quality workmanship.

21 -

Maintenance personnel are attentive.to '

22 identifying and are responsive to correcting l 23 plant deficiencies with a goal of maintaining

[) 24 equipment / systems in an optimum material '

25 condition. t 26 -

Managers and supervisors routinely observe 27 maintenance activities to identify and 28 correct problems and-to ensure adherence to  ;

29 station policies and procedures including 3 30 industrial safety and radiation protection.

t 31 This is an important aspect of maintenance 32 performance. The conduct of. maintenance is not as 3 131

(

F i

I 3 )-

l l

1 visible as the plant material condition, but is an j 3 2 important indicator of the way that the results are l 3 obtained. Some examples of my observations on the 4 conduct of maintenance at Diablo Canyon follow:

D 5 .

  • Everyone that I observed out in the plant was very 6 conscious of industrial safety work practices. i 7 They all wore their safety equipment and were O 8 careful that all security and fire doors were 9 secured behind them. This showed me that the 10 habit of doing things right is a part of their 3 11 daily work. It has been my experience that it is 12 very difficult to get hundreds of people to do all 13 these small daily activities consistently well.

3 14

  • During my tours of the plant, I noted many times 15 that supervisors were out in the field. In two 16 cases, I saw the mechanical department head 3 17 inspecting equipment in the plant at different 18 locations and times. In my discussions with him, 19 he displayed a good knowledge of the plant and the 3 20 equipment in it.

21

  • During my tour of the intake area, I was impressed 22 with the area foreman's knowledge of and 3 23 commitment to the intake area. He was obviously 24 very enthusiastic about his work. He readily i

25 answered all of my questions, and in many cases 26 anticipated where I was leading to and volunteered

! 27 much more information. An example of this was on l 28 a question I had about the intake crane. He not i

3- 132

D-1 only answered my questions, but told me what the 2 plans were for future work on the crane. He 3

3 discussed experience they had on the cables, the  !

4 plans to replace the cables with stainless, and

) 5 the schedule for non-destructive examination of 6 the hook. The crane had recently been included in 7 a plant-wide crane inspection program. Such

) 8 knowledge and enthusiasm is a clear example, in my 9 mind, of a very healthy commitment to the ,

10 effective conduct of maintenance. Such i

) 11 outstanding examples would not exist, I believe, i

12 unless a strong culture exists at the plant to 13 support it. ,

During my tour of the high voltage switchgear

) 14

  • l 15 rooms, I noted a significant work activity where  !

l' 16 large steel beams were being added to stiffen the l

) 17 walls. This was in response to a seismic upgrade.  !

i 18 This work involved cutting, welding, grinding, 19 painting, and chipping in the relatively small l space between the switchgear cabinets and the

) 20 1

21 walls. The area had been very effectively -

22 controlled by the manner in which the scaffolding i had been erected, and clear, yellow plastic was

) 23 24 draped to prevent arc flashes from harming people 25 and dust from escaping fron the work area. This i 1

26 is a good example of effective conduct of

)

27 maintenance.

W - .- L .- y . v. w.

b i i

I believe these are examples wherein the 1

I j 2 maintenance program is being implemented very well at 3 Diablo Canyon. l 1

g-4 Q13 Did you observe a Preventive Maintenance Program 5 at Diablo Canyon?

t 6 A13

  • Preventive Maintenance 7 Performance Objective: Preventive maintenance ,

8 should contribute to optimum performance and 9 reliability of plant systems and equipment.

10 criteria:

11 -

A preventive maintenance program is 12 effectively implemented and includes systems 13 and equipment that affect safe and reliable

[ 14 plant operation.

) 15 - Preventive maintenance, includinq predictive 16 maintenance activities, are performed at 17 appropriate intervals. These intervals 18 maximize equipment availability.

l 19 Considerations such as operational 20 experience, vendor recommendations, 21 engineering analysis, and cost / benefit 22 analysis are used as a basis to establish ,

23 preventive maintenance tasks and intervals.

24 -

Preventive and maintenance activities are  ;

25 scheduled and performed within established 26 intervals. Preventive maintenance is waived l

27 or deferred only with management approval.

i l

28 Yes. Some observations related to preventive i

29 maintenance made during my plant tour follow:

30

  • The implementation of activities for preventive 31 maintenance are done by the respective maintenance 32 organizations. The development and coordination

) '

33 of specific preventive maintenance activities is 34 the responsibility of the Preventive Maintenance  ;

134

)

. . ~ ,_ _ ..

i i

1 Engineering Group. They are responsible for the r

) 2 technical aspect of preventive maintenance 3 activities and for determining the proper 4 frequency of the activities. The Group includes

) 5 representatives from the maintenance disciplines.

6 The Group reviews vendor recommendations, i

7 technical manuals, data provided by Reliability

) 8 Engineering, and equipment history files which .

9 include all action requests for that piece of 10 equipment. This appeared to be a comprehensive 3 11 and effective process and the overall plant 12 equipment condition reinforces this view.

13

  • Diablo Canyon is implementing a reliability 3 14 centered maintenance ("RCM") project. This is an ,

15 ongoing effort, the results of which are available 16 plant-wide on their computer-based information

) 17 management system (known as "PIMS"). The basis of 18 why an activity is or is not recommended is 19 documented and can be referred to in the future to 20 support why a certain activity is recommended.

21 Factors included are:

22 -

why it is a critical component 3 23 -

what the RCM analysis results are  !

24 -

what the system engineer analysis was ,

I i 25 -

what the vendor recommendations are 26 This RCM project is an effort by the maintenance l 27 organization to improve the performance of the 28 plant equipment. This project appears to receive .

135

9 1 high levels of commitment from management as it G 2 was mentioned by several management-level people 3 in discussions with them. This is an example, in 4 my view, of an organization that is looking for 9 5 ways to constantly improve its performance.

6

  • The preventive maintenance program also ties in 7 with the Inservice Inspection / Inservice Testing 3 8 and performance monitoring activities at the 9 plant.

10 It is my conclusion that the preventive 3 11 maintenance program at Diablo Canyon is in place to 12 improve equipment performance.

3 13 Q14 Please address your next criterion, Maintenance 14 Procedures and Documentation.

1 Q15 Does PGEE compile and evaluate Maintenance 3- 2 Histories? -

3 A15

  • Maintenance History O 4 Performance Objective: Maintenance history should 5 be used to support maintenance activities, upgrade i 6 maintenance programs, optimize equipment 7 performance, and improve equipment reliability.

8 Criteria: Maintenance history records are 1 O 9 maintained for systems, equipment, and components l 10 that affect safe and reliable plant operations.

11 Yes. Based on my discussion with maintenance i

12 personnel, reliability engineering personnel, O

13 preventive maintenance engineering, as well as some  !

14 system engineering personnel, and upon my procedure 15 review, I believe it is reasonable to conclude that O

16 Diablo Canyon has an effective maintenance history 17 program. Some of my observations are:

18

  • All of the action requests for a piece of C

19 equipment are permanently added to the 20 computerized history file. This aids in the 21 determination of equipment performance and i O

evaluation of the effectiveness of preventive l 22 23 maintenance activities.

24

  • The reliability centered maintenance project l b information is entered into equipment history.

3 Q16 Please address your next criterion, Maintenance O 4 Facilities and Equipment.

5 A16

  • Maintenance Facilities and Ecuipment.

O 6 Performance Objective: Facilities and 7 equipment should effectively support the 8 performance of maintenance activities.

9 Criteria:

O 10 -

Maintenance facilities size and 11 arrangement promote the safe and 12 effective completion of work.

13 -

Measuring and test equipment (M&TE) is 14 calibrated and controlled to provide g 15 accuracy and traceability. Out-of-16 tolerance test equipment is removed from 17 service. Plant equipment calibrated 18 with out-of-tolerance test equipment is 19 evaluated in a timely manner for 20 operability, and is recalibrated as e 21 necessary.

22 Diablo Canyon has excellent facilities. The plant 23 as a whole has excellent facilities and the maintenance g 24 facilities are outstanding. During my tour of the 25 plant, I had an opportunity to see most of the 26 maintenance facilities, as well as the training e 27 facilities. Some specific examples follow:

2B

  • There is a very good light machine shop and 29 mechanical facility between the units in the e 30 turbine building. This shop was very spacious and 31 very well equipped. There were four lathes, two 1

32 milling machines, and several smaller power tools

@ 139

-)

1 such as drill presses and grinders. It was also O 2 equipped with a nice overhead crane.

3

  • The intake structure has its own free-standing 4 workshop area that is almost as large and well-O 5 equipped as the maintenance shop described above.

6 They also have an office and break / lunch building.

7 They have many special tools used in the repair of O 8 intake equipment.

9

  • The I&C shop was very spacious and well-equipped 10 for a large number of I&C workers (I think I O 11 counted about 80 benches).

12 o The M&TE calibration shop was the best I have ever 13 seen. PG&E has the capability at Diablo Canyon to O 14 calibrate most equipment used in the plant; the 15 shop acts as a common calibration shop for all 16 M&TE equipment on site including health physics.

O 17 The calibration equipment was all in excellent 18 shape and the storage of calibrated equipment was 19 also excellent. PG&E separates the uncalibrated O. 20 instruments from the calibrated instruments, and 21 the history of individual calibrations is kept in 22 a computer history program. All jobs that an O 23 instrument was used on are kept in this history, 24 so if an instrument is found out of calibration 25 the work that was done with it is immediately ,

8 26 known. The individual that took me through the l

27 shop was quick to point out the many strengths in l l

28 this shop and demonstrated them to me. This is m

'> 140

i i

1 another example of a very knowledgeable person D 2 readily able to demonstrate the effectiveness of 3 the work they do. Highlights pointed out to me l 4 included the optical scanner used to identify both j 5 the M&TE equipment as well as the individual who 6 checks it out. ,

7

  • The training facilities were also very good. I  ;

D 8 will discuss them more in the element on training. I i

9 In summary, I believe that Diablo Canyon's r

10 facilities would compare favorably to any nuclear D 11 facility in the United States. ,

g 9 practices 10 During my inspection of the plant, and in 11 discussions with plant personnel as part of my review 12 of the maintenance program, I had many opportunities to 3

13 observe the knowledge and performance of maintenance 14 personnel. Some of my observations are as follows:

3 15

  • My discussion and tour with the Mechanical 16 Department head revealed that he was very 17 knowledgeable about the plant equipment and the
g 18 programs and processes used to maintain the 19 equipment.

20

  • The Electrical Department supervisor, who g 21 discussed Generic Letter 89-10 activities with me, 22 was very knowledgeable about the program and 23 equipment related to motor operated valves.
p 24
  • As I indicated in my comments on the M&TE shop, 25 the people who were associated with M&TE were 26 extremely knowledgeable of that program and how it 25 fits in with the rest of the plant activities.

3 28

  • I will discuss this more later, but the training 29 supervisor for Maintenance demonstrated a strong

, 30 knowledge of the training aspect of maintenance, 31 as well as knowledge of how some of the training 142 3

[) I i

1 facilities are used to do maintenance on equipment 3 2 from the plant.

3

  • The area foreman for the intake area was extremely 4 knowledgeable about this area. I covered this in 3 5 the element on plant material condition, but it is 6 a very good example of personnel knowledge and 7 bears repeating.

7) 8

  • I observed discussions between the foreman and 9 some of the crew members related to work at the 10 intake structure. Based on the comments and 11 d tail f the discussions, I would say that the O

12 journeymen were very knowledgeable about the work 13 being performed.

14 I conclude that this element is being effectively

[)

15 implemented at Diablo Canyon.

16 Q18 Please describe what you observed regarding the 7) 17 Technical Support Organization and Administration 18 Performance Objective, p

19 A18

  • Technical Succort Oroanization and Administration 20 Performance Objective: Technical support

[ 21 organization and administration should ensure 9 22 effective implementation and control of j 23 technical support.

24 Criteria:

25 -

The organizational structure is clearly g 26 defined.

27 -

Staffing and resources are sufficient to 28 accomplish assigned tasks.

29 -

Responsibilities and authority for each 30 management, supervisory, and 143 3

l-l 1 professional position are clearly 2 defined and understood.

O 3 -

Interfaces with support groups, I 4 including corporate groups and contract 5 services, are clearly defined and 6 understood.

7 -

Technical support personnel have 8 sufficient expertise regarding plant O 9 systems, components, and operations to 10 effectively investigate and resolve 11 plant problems.

12 My discussions with plant staff and my review of O 13 plant and corporate procedures show that the technical 14 support function is well established at Diablo Canyon.

15 Some specific observations follow:

O 16 . The data trending of equipment performance done by 17 the Reliability Engineering group is analyzed and 18 the results forwarded to preventive maintenance O 19 engineering. This is a good example of technical 20 support.

21

  • The tie between the several department O 22 organizations needed to implement IsI, IsT, and 23 equipment qualification is generally clear and 24 well understood by the individuals involved.

O 25 . The motor operated valve activities are covered by 26 a program plan document that formalizes the plant

27 efforts to comply with GL 89-10.

l C- 28

  • The corporate level aging document mentioned 29 earlier is also an example of effective technical

=

30 support.

31 I believe these examples show that this element is 32 clearly in place and is being implemented well.

[) 144 l

O 1 Q19 Please address the Surveillance Testing Programs ,

O 2 A19 e Surveillance Testina Procrams 3 Performance Objective: Surveillance O 4 inspection and testing activities should 5 provide assurance that equipment needed for 6 safe and reliable plant operation will 7 perform within required limits. ,

8 Criteria:

O 9 - Administrative systems and controls 10 ensure timely completion and review of 11 required surveillances.

12 -

Surveillance testing programs result in 13 a high degree of reliability of 14 equipment needed for safe and reliable 9 15 plant operations.

16 - Procedures used for surveillance testing .

17 contain. sufficient detail to ensure safe 18 plant operation during testing and 19 provide for consistent test performance O 20 and accurate results. Procedures ,

21 simulate, as near as practical, the 22 actual conditions under which the system 23 must operate on demand.

24 In assessing the effectiveness of this element, I O interviewed a number of plant personnel and made 25 26 specific observations of equipment and work being 27 performed:

O The 28

  • The IST program appears to be well-defined.

29 supervisor of this program was very knowledgeable 30 about the requirements of IST. He pointed out to O me that they have a program document that clearly 31 32 states the relationships of the many activities 33 involved in completing the IST program 9 34 requirements. We discussed in detail how this  ;

35 program relates to check valve inspections ,

36 performed by Mechanical Maintenance. This area is

.O 145

l h-

~1 often one that is not well integrated and leaves D 2 room for some problems. I believe that Diablo 3 Canyon has done an adequate job of ensuring good P

4 compliance of these two programs.

O 5

  • The implementation of the ISI program appears to 6 be very good.

7

  • The implementation of environmental qualification O 8 by the different maintenance departments is also 9 very good.

10

  • The implementation of the motor-operated valve O 11 program is very strong. As I mentioned earlier, ,

I 12 PG&E has a program plan document that shows the 13 relationship of the different organizations that O 14 must coordinate well in the compliance to 15 GL 89-10. ,

3 4 Discussions with plant staff and inspection of  !

5 equipment provided me with the following examples for g 6 this element: ,

7

  • The gathering, trending, and analyzing of data i

8 done by Reliability Engineering is a good example j t

9 of this element.

9 10

  • The RCM/ preventive maintenance activities also support plant performance monitoring.  !

11 12

  • The IST and ISI programs contribute to plant <

3 13 performance monitoring very well.  !

14

  • The actual valve testing of motor operated valves 1

15 is a part of performance monitoring.

3 16

  • I believe that NRC SALP assessments, while not a 17 direct measure of plant performance, are a very t

18 good indication of the plant performance. A 3

19 review of the most recent SALP for Diablo Canyon .

20 satisfied me that PG&E is performing its licensed 3 21 responsibilities very well.

22 Q21 What were your observations regarding Maintenance 23 Personnel Training and Qualification?

3 l

l 24 A21

  • Maintenance Personnel Trainina and Oualification Performance Objective: The maintenance

) 25 26 personnel training and qualification program 27 should develop and improve the knowledge and 28 skills necessary to perform assigned job 29 functions.

147 3

D 1 1 Criteria: Programs are established and 2 implemented for initial and continuing

) 3 training.

4 A significant contributor to maintenance strength 5 is training. A key indicator to the health of this

) 6 relationship is the attitude that maintenance has for 7 training and that training has for maintenance. I 8 observed a number of things that show me Diablo Canyon

3) 9 has a very healthy relationship: l 10
  • I got very clear feedback from the maintenance l

11 manager that he is a strong supporter of training.

12 I also heard from at least two of his division 13 directors that he is a strong supporter of 14 training.

) 15

  • The maintenance training supervisor attends the r

16 Maintenance Department's morning meeting each day 17 instead of his own training division morning 18 meeting.

19 e on a tour of the maintenance training facilities, 20 it was clear that training was well supported with 3 21 equipment and mock-ups. Some specific examples 22 are:

23 - The reactor coolant pump / seal mock-up was 3 24 about as realistic as it could be. It is 25 full-scale and is made of the actual 26 materials. This provides for a very ]l i

) 27 realistic training aid. Reactor coolant pump l

[ 2 outage activities, and radiation exposure.

l 3 -

They have a full-sized, real emergency diesel i

4 engine in training.

) 5 -

The electrical training area has a wide ,

l 6 variety of motor operated valve operators. .;

7 This would provide very important training in b 8 the proper maintenance of MOVs. .j 9 -

The I&C Lab was exceptional in my experience.

l 10 They have one channel of the reactor 11 protection system with all of the components, 12 including actual control rod drive motors and-13 drive shafts and rod position indication. l j  !

le This facility is so realistic that they bring l t i

15 electronic circuit boards from the plant and  ;

16 troubleshoot them on the training aid. [

t r b' 17 -

There were classes going on in all three  ;

18 disciplines during my tour.

19 - About one-third of the training staff go to  !

16 Q23 How does PGEE address the element of maintenance 17 related to operating experience reviews?

)

18 A23

  • In-House Operatina Experience Review 19 Performance Objective: In-house operating 20 experience should be evaluated, and 21 appropriate actions should be undertaken to 3 22 improve safety and reliability.  ;

23 Criteria:

24 -

In-house events are screened for 25 significance and prioritized for 26 evaluation.

) 27 -

Rigorous investigation is performed on 28 significant in-house events to determine i 29 root causes, generic implications, and 30 necessary corrective actions to prevent  !

31 recurrence.

32 Several examples of effective use of in-house 33 operating experience were evident to me:

i

)

t.

150 i l

i lO 1

  • The plant-wide use of computerized action request O 2 ("AR") forms seems to strengthen the availability 3 of in-house information. All AR forms are 4 trackable via computer, so any issue can be I) 5 tracked to see if it is being responded to 6 properly.

7

  • The AR is a permanent part of equipment -

() 8 maintenance history and figures in on the schedule 9 of work to be done and the tracking and trending 10 of repetitive failures.

O 11

  • An interesting aspect to ARs for me is that they 12 can be for any type of problem. They do not have 13 to be for equipment deficiencies, but can be for O 14 program and process problems. This allows for a 15 very wide range of issues to be identified. This 16 seems to me to be an indication of an organization O 17 that is not afraid of criticism and change for the 18 better.

19

  • While it is not clear who has accountability for O 20 root cause analysis (a situation also true at 21 other facilities), it seems to be because 22 everybody has accountability for it. Every time I

.O 23 asked, "Who had accountability for root cause?,"

24 the answer was, "I do," or "we do," or "here's how 25 it works," with a ready explanation. Significant

- t O 26 problems are addressed with an officially formed 27 team dedicated to whatever the problem is.

3 Q24 Did you observe any system for Industry Operating 4 Experience review?

O ,

5 A24

  • Industry Operating Experience Review 6 Performance Objective: Significant industry 0 7 operating experiences should be evaluated, 8 and appropriate actions should be undertaken ,

9 to improve safety and reliability.

10 Criteria:

O 11 -

A comprehensive evaluation is performed 12 on applicable, significant industry r 13 operating experience, and appropriate ,

14 corrective action is completed in a 15 timely manner.

16 -

Sources of significant industry O 17 experience information reviewed for 18 applicability include the following:

26 e. NRC letters, bulletins, and 27 information notices O. 28 f. Supplier and architect / engineer 29 reports 30 Most of the examples I provided for in-house 31 operating experience also apply to industry experience.

g 32 However, several additional observations are warranted:

33

  • The success that Diablo Canyon has had with ,

O 34 respe t t the MOV/GL 89-10 issue is an indication 35 that they are effectively in touch with the rest ,

36 of the industry.

152 O ,

O 1

  • Changes to the IST program reflect a strong tie O 2 with industry issues.

3 e The check valve program is one that has 4 effectively responded to industry activities.

5 Diablo Canyon performs a self-evaluation prior to

()

  • 6 their INPO evaluation. They utilize the help of 7 peer evaluators from other plants to do this.

() 8 This evaluation appears to be more rigorous to me 9 than the actual INPO evaluation. They have about 10 28 people working for three weeks looking at all

() 11 areas. From the number of findings and the detail 12 involved, it is clear to me that the intent is to 13 find the weaknesses themselves and to strengthen

() 14 the performance from self-identified issues. This 15 is an indication of a very healthy organization.

) 16 Q25 What do you conclude overall from your review?

l l 17 A25 Based upon my review, I am satisfied that Diablo

() 18 Canyon does in fact have a comprehensive and effective 19 maintenance program. While there may be individual

! 20 deficiencies in the implementation of the programs, the t) 21 overall strength of the programs provides for 22 corrective action and continued improvement.

l 9

1 3 153

D 1 Q26 In raising Contention I, MFP cited a number of 3 2 incidents and reports that they believe show the Diablo 3 Canyon maintenance program to be less than adequate, or 4 at least less than adequately implemented. Do these 5 citations affect your view of the Diablo Canyon 6 program?

) 7 A26 I have not reviewed all of these incidents and 8 citations in detail. However, I am familiar with the 9 types of incidents and reports referenced. These do 10 not change my overall conclusions.

11 From my experience., it is unreasonable to expect, 12 given the complexity of a commercial nuclear power

) 13 plant, that there will not occasionally arise a 14 confluence of events that creates an unsatisfactory 15 condition. This is not to minimize the role that O 16 nuclear safety must play in operating a nuclear power j 17 plant. Nuclear safety nust be paramount. Eliminating 18 safety problems is of the utmost importance. It must 19 be the first consideration given to any situation. It 20 is extremely important that great initiative is given 21 to anticipating and preventing safety problems. In my 3 22 opinion, a healthy organization is one that is self-23 examining by nature, does not obscure the facts of a 24 situation, is ready to take responsibility for

) 25 problems, and initiates quick, effective corrective 26 action. During my observations at Diablo Canyon, I 27 found many instances to show that Diablo Canyon is such 3 154

r i O r r

1 a healthy organization and found no condition, word, or O 2 deed to suggest otherwise.  !

3 Being alert to potential problems, ensuring that 4 problems are identified, making sure that problems are i O 5 entered on the proper tracking list, and taking timely, 6 effective corrective action on those problems are all i

i 7 signs of a healthy environment. Indeed, to suggest

() 8 that the identification of a problem was a weakness t

9 would reduce the probability of correcting it.

l

O 10 Q27 MFP also speculates in their contention that PGEE ,

11 is guilty of putting off necessary maintenance to keep 12 the plant running and to maximize profits. Did you see

() 13 any evidence of this occurring at Diablo Canyon?

p O 14 A27 No. Furthermore, the speculation seems to me to c ,

15 be completely unrealistic. It assumes that you can run 16 a nuclear power plant just because you want to. If all f l '

l O 17 it took was a high level manager saying "you are going ,

\

18 to run," all nuclear power plants would have 100 i 19 percent capacity factors. It is not that easy! It is i

i O 20 very difficult to keep the equipment running reliably. ]

l 21 It takes a strong commitment at a high level, as well l

22 as a great deal of effort and experience. It has been e

O 23 my observation that only a very strong organization 24 with a resolute commitment to success can keep a 0 155 L _- _

i l i l 1 nuclear power plant running at a high capacity factor 2 over a long time.

3 Being able to maintain a high capacity factor l .

4 demonstrates in my mind the existence of strong D 5 programs. Once you have an organization that does 6 things well in one area, they tend to try to do things 7 well in all areas. I believe that the existence of a 8 consistently high capacity factor is the mark of a 9 well-run and well-maintained plant and, therefore, the 10 mark of a safely-run plant. ,

D 11 Q28 Do you have any additional observations?

D 12 A28 Let me make some final general observations. One l

13 of the examples that I have referred to in my testimony i

14 is the scaffold tagging program. It is my direct D 15 observation that this is an effective program at Diablo 16 Canyon. I believe that this observation has more i

17 significance than just a good scaffold program.

D 18 Some factors relating to scaffold tagging follow: ,

19

  • It is relatively low on the priority list of 20 important things done at a nuclear power plant.

D- If you were going to cut corners, it would be a 21 *

22 place to do it.

L

! 23

  • It takes a while, in my experience, for an I

24 organization to recognize that controlling l 25 scaffold tagging is necessary. ,

l

)

l 156 l^ t I i

D 1

  • It is a fairly cumbersome process, as there are at 2 least five areas that are important and need to be 3 addressed in the process:

4 -

Fire (as a transient fire load)

C 5 -

Chemical (as a hydrogen release agent in 6 containment) 7 -

Seismic (as a missile or attachment to C 8 adjacent equipment) 9 -

Ventilation (flow blockage to equipment) 10 -

Industrial safety (slips, falls, dropped C 11 objects, and blocked exits) 12 e It is difficult to control as many different 13 people build and use scaffolds in many areas of C 14 the plant. In most cases, there is nothing to 15 physically prevent them from building and using a 16 scaffold.

17

  • It takes a while for an organization to figure out 18 how to effectively control scaffold use.

19 e It takes a while longer, and some considerable 20 effort, to make it work.

21 There are several conclusions that I believe can l

22 rightfully be drawn from having an effective scaffold h 23 control program:

24

  • You are not cutting corners. If you are doing 25 something like this well, you are probably also O 26 doing more important work well too.

27

  • You have been paying attention to problems in your 28 organization.

O 157

I I i

I l

1

  • You can develop and administer a relatively b 2 cumbersome process.

3 e Your people can tell that you think it is 4 important and therefore other things are important Y 5 too.

6 In this light, my observations of the scaffolding 7 program at Diablo Canyon increase my confidence b 8 regarding the overall effectiveness of the maintenance 9 program and the organization.  !

10 I believe that the same general conclusion can be 0 11 drawn from other programs by my direct observation:

12

  • Equipment clearances 13
  • Equipment tagging O 14 . not work permits 15
  • Attention to personnel safety 16
  • Attention to fire and security doors 17 From my observations, PG&E appears to be effective 18 in these areas as well.

19 Finally, I want to reiterate that the plant is in

)

16 Q1 Please state your name, affiliation, qualifications 17 and current job responsibilities.

)

18 A1 (Giffin) My name is Bryant W. Giffin. I am the 19 Manager of Maintenance Services for Pacific Gas and 20 Electric Company ("PG&E") at the Diablo Canyon Power Plant 21 ("DCPP"). I am responsible for all maintenance and outage 22 activities at DCPP. I have more than 25 years experience 23 working in the nuclear industry; 12 years with PG&E and

)

24 over 13 years as an officer in the United States Navy's 25 nuclear power program. A summary of my professional 26 qualifications and experience is provided in Exhibit 1.

27 (Miklush) My name is David B. Miklush. I am the 28 Manager of Operational Services for PG&E at DCPP. I am

) 160

O 1 responsible for Operations, Chemistry, and Environmental J 2 Engineering. I have more than 20 years experience in the 3 nuclear industry, and have been working at DCPP for more 4 than 15 years. I maintained an SRO license at DCPP from J 5 1982 to 1988. A sutrary of my qualifications and 6 experience is provided in Exhibit 13.

J 7 II. PERFORMANCE EVALUATION OF DCPP'S MAINTENANCE AND 8 SURVEILLANCE PROGRAMS 3 9 Introduction 10 Q2 What performance measures does PG&E use to determine 11 the effec'.iveness of the DCPP maintenance and surveillance 3 12 programs? How have the DCPP maintenance and surveillance 13 programs performed under each of these performance 14 measures over the last two SALP periods?

O 15 A2 (All) One of PG&E's most important corporate goals is 16 to " Operate the Diablo Canyon Nuclear Power Plant at the D 17 highest level of safety, reliability, and performance."

13 In order to meet this goal, the Nuclear Power Generation 19 Business Unit ("NPG"), which includes DCPP, has defined O 20 its goals and objectives in Program Directive OM2, 21 " Management Goals and Objectives." NPG's goals are 22 prepared annually and are formulated in the following e 23 categories:

24 e Safety and Quality of Operations 25

  • Energy Production 0 161

O 1

  • Cost Management O 2 . continuous Improvement 3 Maintenance activities have a large impact on how NPG 4 performs in meeting its goals. Maintenance effectiveness O 5 is not merely a function of day-to-day, individual 6 preventive and corrective maintenance tasks. A well 7 maintained plant exhibits long, uneventful runs between O 8 refueling outages with plant generation at a high percentage of generating capacity. Uneventful runs r

9 mean 10 minimal plant transients. High operating capacity factors 0 11 (percentage of maximum generation capability actually 12 delivered between outages) result in efficient delivery of .

13 energy to customers. Thus, in a programmatic sense, the O 14 effectiveness of maintenance is demonstrated by the 15 overall safe and reliable operation of the plant over 16 time.

O 17 With this in mind, NPG uses three broad performance 18 measures to evaluate the comprehensiveness and 2 19 effectiveness of the DCPP maintenance program in meeting  ;

O, 20 PG&E's corporate goal for DCPP. These performance 21 measures include:

22 o Plant Operating Performance, ,

O 23 e Maintenance Services Department Goals and Objectives,  !

24 and i

25

  • Regulatory Performance  !

O 26 Each of these performance measures will be discussed 27 below.

O 162

9 1 Plant Operatinc Performance 9 2 Q3 How does plant operating performance demonstrate the 3 effectiveness of DCPP's maintenance and surveillance 4 Programs?

O t

5 A3 (All) Experience has demonstrated that nuclear plants 6 with consistently high capacity factors, long continuous

  1. 7 operation, and short refueling outages are also the best 8 maintained plants. This is because reliable and 9 continuous operation at high capacity factors between S 10 scheduled refueling outages and across many operating 11 cycles simply cannot be sustained unless plant equipment 12 and facilities are maintained in a superb condition. In O 13 turn, reliable, event-free operation results in fewer 14 challenges to plant safety systems and less wear and tear 15 on safety equipment. Thus, good maintenance practices are O 16 not only evidenced by reliable plant operation, but 17 reliable plant operation itself reduces the wear and tear 18 that can lead to increased maintenance.

O 19 Diablo Canyon's operating history provides ample 20 evidence of the effectiveness of the DCPP maintenance 21 program. The combined lifetime capacity factor for both O 22 Diablo Canyon units since Unit 1 began commercial 23 generation in 1985 through July 1993 is 78 percent 24 including refuelings. In this respect, the Diablo Canyon

  1. 25 units are among the best operating nuclear units in the 26 nation. DCPP's capacity factor has steadily improved from 27 year to year over its operating history. Over the last 163

O 1 three years (1990-1992), the combined capacity factor for O 2 both Diablo units has been 85 percent. See Exhibit 14.

3 Among all nuclear plants worldwide, Diablo's performance  !

4 consistently ranks among the best.

O 5 Q4 What measures are there of operating performance?

Q 6 A4 (All) A plant's overall operating performance is 7 defined by two components: (1) capacity factor between 8 refuelings, and (2) duration of its refueling outages. A g 9 commonly used measure of performance for the first is 10 " operating capacity factor," the percent of maximum 11 generation that is achieved from the time the breakers are g 12 closed at the end of a refueling outage, to the time power 13 production ends when the breakers are opened again at the 14 next refueling outage.  !

O 15 QS Please address DCPP's performance in terms of capacity 16 factor.

O 17 AS (All) For a plant like Diablo Canyon with constant ,

18 tempe.rature ocean cooling, a 100 percent operating O 19 capacity factor is not attainable since the plant goes 20 through a period of power ascension testing coming out of [

21 an outage. Moreover, ocean-cooled plants like DCPP need 22 to conduct periodic scraping of the intake tunnels at i

.O 23 reduced power to remove barnacles and other sea life.  ;

I O 164 ,

1

O 1 Diablo Canyon's operating capacity factor has averaged 3 2 95 percent over the last three years, has been over 92 3 percent each year over the last five years including 1993 4 year-to-date, and reached over 96 percent in 1992. See O 5 Exhibit 15. This is the best among similar plants in the 6 United States, and consistently among the very best of all 7 nuclear plants worldwide. In 1991, Unit 2 set a world D 8 record for length of continuous run, 481 days at power, 9 breaker-to-breaker between refueling outages. World class 10 performance like this is not achieved without a superb O 11 maintenance program. This is a further indication that 12 PG&E's preventive maintenance program has been effective 13 in precluding equipment failure and forced outages across O 14 multiple operating cycles.

15 Another, and perhaps more subtle, reason that our 16 excellent plant operating capacity factor is indicative of D 17 an effective maintenance program has to do with the 18 numerous Technical Specification surveillance tests which 19 are required to be performed during operation on the O 20 thousands of SSCs important to safety. All of these 21 surveillances have Technical Specification mandated 22 " ACTION STATEMENTS" which are required to be initiated if 9 23 an SSC is not operable because the surveillance result is 24 not satisfactory in every respect. This includes all )

25 supporting equipment, administrative requirements and test 8 26 results. The great majority of these " ACTION STATEMENTS" 27 require the plant to begin reducing power toward shutdown 28 if the problem is not fully resolved within a limited 8 165

O 1 period of time. To achieve a consistently high plant O operating capacity factor, the plant's maintenance program 2

3 must maintain and test SSCs in a well coordinated manner 4 at a very high level of performance to avoid " ACTION O 5 STATEMENT" power reduction or unit shut-down.

6 Q6 How is DCPP's performance of maintenance reflected in O 7 the duration of planned refueling outages?

8 A6 (Giffin) Certain periodic maintenance activities are O 9 performed every refueling outage, and the duration of the 10 outage (along with event-free post-outage operation) is an 11 indicator of how efficiently outage maintenance activities 12 are planned, scheduled and performed by a skilled, 13 highly-trained workforce. Since DCPP began operation in 14 1985, refueling outage times have been cut in half. See 15 Exhibit 16. DCPP refueling cutages are now consistently 16 among the shortest in the industry. In 1992, even with 17 the additional scope of DCPP's ten-year ISI anu reactor O 18 vessel steam generator shotpeening work, the Unit 1 fifth 19 refueling outage took only 59 days, a record for the unit.

20 In 1993, Unit 2 completed a similar scope refueling outage O This performance set a United States record 21 in 57 days.

22 for Westinghouse and Combustion Engineering plants 23 undergoing a 10-year ISI refueling outage. These short 4 24 outage durations reflect the comprehensive training of 25 DCPP maintenance personnel and thorough planning of 26 maintenance activities necessary to perform outage 9 166

) ,

1 maintenance tasks. The quality of the work performed has 3 2 a been demonstrated by the reliable, event-free operation ,

3 of both units since the outages were completed. Once 4 again, DCPP's consistency and quality are the hallmarks of J 5 a top-flight maintenance program. '

6 Maintenance Goals and Obiectives

) 7 Q7 How do DCPP's internal goals and objectives measure ,

8 the effectiveness of the DCPP maintenance program?

J 9 A7 (Giffin) As discussed previously, PG&E uses a 10 formalized set of goals and objectives for managing DCPP.

11 The objectives established for the Maintenance Services

) 12 Department are a subset of DCPP's overall goals, and 13 provide constant feedback to the workforce and to senior 14 management concerning overall effectiveness in the key

) 15 areas of maintenance activities. Each of these internal 16 indicators provides a different view of the process to a 17 specific organizational level or group. Some are i J 18 quantitative reports generated from PIMS records and some 19 are based on qualitative assessments. A comprehensive ,

20 analysis of maintenance performance is dependent on a D 21 review of all available data at any given point in time.  !

22 The primary Maintenance Services Department objectives 23 include:

) 24

  • Industrial Safety 25
  • Radiation Exposure 26
  • Personnel Contamination

) 167

  • Personnel Error Reduction O 2
  • Refueling outages 3
  • Corrective Maintenance Backlog ,

  • Overdue Preventive Maintenance Items O 5
  • Ratio of Preventive Maintenance to Total Maintenance 6 DCPP's performance in each area is discussed below.

f Q 7 1. Industrial Safety 8 Q8 How has DCPP performed relative to its industrial 9 safety goal in the maintenance area?

O 10 A8 (All) DCPP's industrial safety accident rate overall 11 has been 0.22 per 200,000 man-hours, substantially better O 12 than the U.S. nuclear industry median of 0.77 and the U.S.

13 best quartile of 0.27 per 200,000 man-hours. A culture i 14 which stresses attention to detail to produce safe working

,O 15 conditions also promotes professionalism and quality 16 overall.

17 The Maintenance Services Department experienced four ,

O. 18 industrial injuries in 1990, zero in 1991, and one in s 19 1992. So far in 1993, there has been only one injury. [

l 20 Even though Maintenance Services has not met its stated O 21 objective of reducing industrial accidents to zero, the 22 Department is performing at a rate better than NPG's goal t

23 of 0.5 per 200,000 manhours. DCPP's performance in this 1 O 24 area has usually been the best safety record in PG&E.

{} 168 t

J 1 2. Radiation Exposure 3 2 Q9 How has DCPP performed relative to its goal for 3 minimizing radiation exposure in the maintenance area?

3 4 A9 (All) PG&E establishes a goal each year designed to 5 minimize the radiation exposure that employees receive.

6 It has always been PG&E's philosophy to keep the dose 3 7 as-low-as-reasonably-achievable ("ALARA").

8 DCPP maintenance personnel achieved a collective dose 9 of 95 manrem in 1992 compared to our internal objective of D 10 96 manrem. This year our objective for similar scope of 11 work is 91 manrem and we are projecting a dose of about 60 12 manrem. During 1992, the majority of the dose, as in any 3 13 year, was received during the refueling outage. The dose 14 received in the 1992 Unit 1 outage was higher than we had 15 targeted. Consequently, in order to reduce the dose for D 16 1993, we formed a High Impact Team (" HIT") with the 17 responsibility to understand the reasons for the increased 18 dose and to implement improvements.

3 19 Due in a large part to these HIT team efforts, we were 20 able to reduce the dose received in the 1993 Unit 2 fifth 21 refueling outage by about 30 percent. This reduction is 3 22 also being seen in Maintenance Services personnel dose.

23 The improvement was an outstanding effort. We did as much 24 work in the 1993 refueling outage with fewer people and 4 25 received less exposure.

i 1 3. Personnel Contamination

) 2 Q10 How has DCPP performed relative to its goal for 3 minimizing personnel contamination in the maintenance 4 area? ,

D 5 A10 (All) In 1991 and 1992, Maintenance Services i

6 Department personnel incurred 107 and 87 personnel

) 7 radioactive material contaminations, respectively. This 8 year, we estimate that the number will be about 55.

9 Again, the improvements that we have experienced in this

) 10 area have been due to the efforts of the plant staff. By 11 carefully planning work, taking time and being observant, j

12 it is possible to reduce the number of instances of

) 13 contaminations to almost zero. PG&E has expended 14 substantial effort in developing and providing a training e

15 program to provide workers with the knowledge necessary to

) 16 reduce the potential for contamination.

17 4. Personnel Error Reduction

) 18 Q11 How has DCPP performed on its personnel error 19 reduction goal in the maintenance area? I

) 20 All (All) We have established goals to reduce the number

  • 21 of personnel errors which cause a plant transient or a 22 formal report to a regulatory agency. The goal for 1993

) 23 is 3 for each 1,000,000 hours0 days <br />0 hours <br />0 weeks <br />0 months <br /> worked at the plant. So far 24 this year there have been two instances of personnel

) 170

!O 1 errors which fall into this category (one in maintenance)  !

O 2 which equals approximately 1.7 per 1,000,000 hours0 days <br />0 hours <br />0 weeks <br />0 months <br /> worked.

3 We have seen a continuous decrease in the number of 4 personnel errors since 1989. This is based on a reduction 5 in such events identified in LERs, Quality Evaluations,

-O 6 and Nonconformance Reports. We will continue to devote 7 attention to this area with the ultimate goal of reducing 8 personnel errors to zero.

O .

9 5. Refuelino Outaces g 10 Q12 How has DCPP performed on its goals for refueling  ;

11 outages in the maintenance area? .

g 12 A12 (Giffin) During a refueling outage, over a million man  ;

l 13 hours of work and several thousand work activities are scheduled. Our performance in outage duration, radiation 14 g 15 exposure, and accident rate during refueling outages has I 16 continued to improve. As discussed above, a key indicator 17 related to outage performance is the low level of I

g 18 equipment problems experienced during subsequent 19 operation. The duration of outages at DCPP has been i i

20 reduced by almost 50 percent in the past five years. In-addition, the fact that we were able to reduce the  ;

21 0

22 radiation dose by 30 percent in the recent Unit 2 fifth ,

l l

23 refueling outage is outstanding

r 171 O ,

t

l l 1 6. Corrective Maintenance Backloc

) 2 Q13 How has DCPP performed on its goal for corrective 3 maintenance backlog?

) 4 A13 (Giffin) PG&E tracks the number of outstanding 5 corrective maintenance work requests at DCPP. The 6 objective of this goal is to provide an overall indication 3 7 of the condition of the maintenance program.

8 DCPP has consistently improved its performance on 9 corrective maintenance backlog over the last five years,

) 10 even while DCPP management has continuously raised the 11 " stretch" goal set for this indicator. As Exhibit 17 12 indicates, the corrective maintenance backlog has been

) 13 reduced from about 1,200 items prior to 1989 to about 600 14 items as of the end of July, 1993. Since DCPP performs 15 over 7,000 corrective maintenance work orders on an annual

) 16 basis, this backlog indicator demonstrates an excellent 17 and continuously improving trend in overall backlog I 18 management.

l l

l 19 7. Overdue Preventive Maintenance Items  !

20 Q14 How has DCPP performed relative to its goal for

) 21 minimizing overdue preventive maintenance items? l

> 22 A14 (Giffin) This indicator provides an overall measure 23 of the timeliness of DCPP's Preventive Maintenance ("PM")

24 program. We monitor the number of PM tasks overdue. This 25 number has continued to be reduced because of an 172 1

t O

1 aggressive effort by the maintenance engineers and O 2 craftsmen. See Exhibit 18. What is important is the 3 overall trend, which at DCPP has been positive, i.e.,

4 decreasing. Again, the curve has a consistently O 5 decreasing number of overdue PM tasks for the past five 6 years. At the beginning of 1992 there were 137 overdue PM 7 tasks; this was reduced to 56 by the end of the year, and O 8 PG&E's goal is to reduce that number to 35 by the end of 9 this year. >

l O 10 8. Ratio of Preventive Maintenance to Total 11 Maintenance 12 Q15 How has DCPP performed relative to its goal for the i

O 13 ratio of preventive maintenance to total maintenance?

i l

14 A15 (Giffin) The purpose of the ratio of preventive to O 15 total maintenance indicator is to monitor progress in 16 achieving and maintaining a proactive maintenance program, i

17 DCPP's trend has been steady and positive, and we have 1 O 18 achieved the long-term objective of a 60 percent ratio of l

19 preventive to corrective maintenance over the past three  !

1 j

20- years. This year we have averaged about 68 percent. j

O 21 Oualitative Evaluations and Self-Asses, ents l

22 Q16 Please describe the self-evaluations performed by DCPP O 23 prior to INPO evaluations.

O 173 r

)

1 A16 (Giffin) DCPP conducts a performance-based review of

) 2 the maintenance program once every INPO evaluation period. l 3 This self-evaluation provides for a qualitative assessment 4 of maintenance effectiveness, rather than a quantitative 5 5 score as is generated from the INPO evaluation itself. A 6 final report (Summary of Findings) is produced at the 7 conclusion of each assessment period. This report lists

) 8 the assessment group's findings (both strengths and 9 weaknesses) and recommendations for improvement. This 10 program is viewed as one means of assessing the

) 11 administrative structure, programmatic controls and 12 working environment in the maintenance organization. PG&E :

13 uses the report as a tool for continuously identifying .

) 14 areas for further improvement in our maintenance and other 15 programs.

16 The most recent two self-evaluations were conducted in -

l

) 17 1990 and 1993. In the maintenance and surveillance areas, t 18 as would be expected in these types of self-critical 19 assessments, the evaluations concluded that there were

) .-20 areas which could be improved. Action plans were prepared j 21 and implemented for the 1990 evaluation, and they are  !

22 being prepared and implemented for the draft evaluation )

23 which was distributed in preliminary form in July 1993.

24 (The 1993 evaluation will be finalized prior to the next j 25 INPO evaluation in October 1993.) PG&E management 26 requires that each finding in these self-evaluations be

! 27 formally tracked, responded to, and corrected. In the 1

j 28 case of the specific findings of the 1990 and 1993 self-b 174

9 1 evaluations, the overall corrective actions that need to 3 2 be addressed are to improve maintenance personnel's 3 attention to detail on routine plant evolutions. The 4 Maintenance Services Department is responding to these J 5 issues by using continuous improvement techniques with 6 employee involvement. Even though areas for improvement 7 were identified in these self-assessments, there was no J Ei indication of any programmatic breakdown in maintenance.

9 Maintenance Ouality Assessment 3 10 Q17 How has PG&E's Quality Assurance program assessed the 11 DCPP maintenance program?

3 12 A17 (Giffin) Maintenance Quality Assessments ("MQA"),

13 conducted under the DCPP Quality Assurance Program, audit 14 multiple areas of outage related maintenance and evaluate 8 15 the operational readiness of selected plant systems.

16 The most recent MQA issued May, 1993, included 17 maintenance activities during the Unit 2 fifth refueling

  1. 18 outage. The assessment concluded that each of the audited  !

19 activities had been effectively implemented. The report 20 also stated that the overall quality of maintenance and O 21 technical support demonstrated by each organization 22 provides confidence in the operational readiness of DCPP's 23 systems. Specifically, the audit nated that the steam

  1. 24 generator shctpeening had exceeded all expectations. The 25 planning and coordination led to a well-executed evolution 26 and the work was performed on time and with significantly 9 175

9

)

1 less radiation exposure than anticipated. Also especially

) '2 effective, according to the audit, was the Generic Letter 3 89-10 MOV Testing. Field support by the foremen and 4 Electrical Maintenance engineers facilitated problem D 5 solving and helped keep the work moving smoothly. The 6 audit found some areas for improvement, and these areas i 7 have been documented on quality problem reports.

D 8 There were four Audit Finding Reports issued, three of ,

9 which were not maintenance-related but addressed design 10 documentation problems (associated with four air operated 3 11 valves) which were discovered in the course of the ,

12 assessment. The fourth finding was for incorrect torquing 13 of feedwater regulating valve capscrews to 16 ft-lbs

) 14 rather than the required 19 ft-lbs. These deficiencies did 15 not indicate a lack of programmatic control or overall 16 effectiveness. They are currently being resolved and 3 17 responded to in accordance with DCPP's required 18 procedures.

19 In December 1992, an MQA was issued for the Unit One D 20 fifth refueling outage. This audit also concluded that 21 the maintenance program, technical support of maintenance ,

22 and technical specification surveillance had been l 3 23 effectively implemented. Specifically cited as-effective' 24 were diesel generator maintenance and installation, and 25 calibration and placement into service of the Reactor i

) 26 Vessel Refueling Level Indication System ("RVRLIS"). )

27 Some deficiencies were noted and resulted in six Audit I 28 Finding Reports relating to specific issues, such as an ]

)

176  !

j

)

1 incorrect radiographic test; procedural noncompliance

) 2 regarding reactor vessel water level during reactor head i 3 removal maintenance; incorporation of design criteria 4 memoranda requirements into certain surveillance test

)- 5 procedures; procedural noncompliance in control of some 6 M&TE; airborne radioactive contamination during steam 7 generator shotpeening; and a replacement parts evaluation

) 8 deficiency for a diesel engine fuel oil switch. DCPP has 9 responded with root cause analysis and corrective actions 10 identified for five of the six findings, and corrective

) 11 actions for three of these already have been completed.

12 The sixth, an incorrect radiographic test, is still under 13 investigation to determine if deficiencies exist. l

) 14 Again, these findings did not indicate any 15 programmatic problems, but did provide important feedback 16 to the DCPP maintenance program.

)

17 continuous Procram Improvement 18 Q19 What are some examples of " continuous improvement"

) 19 initiatives involving the DCPP maintenance and 20 surveillance programs?

) 21 A19 (Giffin) PG&E's operating and maintenance strategy 22 for DCPP is focused on continuous improvement. Over the 23 past few years, PG&E has conducted a number of internal

) '24 reviews of the maintenance program as part of its 25 continuous improvement strategy. Although these reviews 26 are specifically targeted at improving the efficiency of

) 177

1 the maintenance process, they provide a mechanism for O evaluating the quality of the maintenance organization in 2

3 terms of its internal processes. Examples of these 4 continuous improvement initiatives include:

O Maintenance Process Improvement Proiect 5 1.

6 In February 1992, DCPP initiated the Maintenance 7 Process Improvement Project. The Project consisted of a O

8 task force made up of employees from all levels of the 9 organization representing the DCFP maintenance process and 10 other related departments and sections. This task force 0 used continuous improvement techniques to identify 11 12 opportunities for improved efficiency in the maintenance 13 process. The Project was completed in December 1992, and O identified four specific recommendations with action plans 14 15 and eleven other recommendations worthy of further

~t 16 evaluation. The four specific recommendations are:

D Establish integrated maintenance teams aligned by 17

  • 18 plant " systems";

19

  • Establish a combined consumables, tools and O

20 equipment group; 21

  • Modify the work priority system to provide an 22 integrated priority system for DCPP maintenance, 23 engineering and procurement personnel; 24
  • Modify the minor maintenance program to improve 25 its utilization.

26 Each of these recommended improvements, along with j 27 necessary computer enhancements, is being implemented and l

l 1 D '

j 178 l

O 1 will add substantial efficiencies to DCPP's overall l

C 2 maintenanca process. )

3 2. Reliability Centered Maintenance 4 PG&E has an active process in place at DCPP to O 5 incorporate reliability centered maintenance ("RCM") '

6 improvements into DCPP's preventive maintenance programs.

7 RCM is a reliability-based methodology for optimizing O 8 preventive maintenance by analyzing the failure modes and 9 safety significance of equipment on a system-by-system 10 basis, and then improving condition-monitoring programs 9 11 for those systems to reflect the insights gained from the 12 analysis. PG&E has completed the first phase of its RCM 13 Program by completing a rigorous system analysis of the O 14 DCPP feedwater system and developing preventive i 15 maintenance program administrative procedures to reflect 16 the RCM process. The second phase of the program is well 0 17 underway at the plant, and involves analysis of 12 18 additional safety-related systems. Currently, the project ;

19 is nearing completion of the fifth and sixth systems (CCW O 20 and 4kV). If the second phase produces positive results, 21 a third phase will perform generic analyses of additional i

22 systems and components, and incorporate the insights into l O 23 DCPP's "Living Preventive Maintenance Program."

24 3. Procurement Task Force 25 In 1991, PG&E completed a multi-disciplinary review of O 26 the procurement process at DCPP. The purpose of this 27 review was to reduce overlap and duplication among various 28 departments, and to improve the reliability and timeliness 0 179 I

! l l >

0 1 of procurement of parts and equipment to support DCPP 2 maintenance and operations. The recommendations of the 3

Task Force have been implemented, and the DCPP procurement 4 organization has achieved a higher level of efficiency and ,

5 timeliness in meeting maintenance needs.

6 Reculatory Performance  !

7 1. NRC Programmatic Assessments i 8 Q20 Please discuss examples of NRC assessments of the DCPP 9 maintenance and surveillance programs. .

'O 10 A20 (All)

As discussed above, the overall operating 11 performance of DCPP, as well as the numerous self-critical ,

'O 12 evaluations conducted by PGLE, are indicators which PG&E  !

13 uses to monitor, arsess and continuously improve the i 14 performance of the DCPP maintenance and surveillance 15 programs. These measures demonstrate that the DCPP maintenance and surveillance programs are comprehensive, \

16 effective and superior. In addition, inspection, 17 J

'O

. 18 enforcement and assessment activities by regulators such as the NRC also provide PG&E with important information l 19 20 concerning the overall performance of all its programs, .

'O including maintenance and surveillance. These NRC 21 i I i 22 activities are discussed below. .

t I 9 i

O 180 i

O 1 a. NRC "Best Plants" List ,

O DCPP is on the NRC "best plants" list. How does this 2 Q21 3 relate to effectiveness of maintenance and surveillance at 4 DCPP?

O 5 A21 PG&E's excellent overall safety performance in 6 operating and maintaining DCPP has been recognized by the O NRC numerous times since issuance of the initial operating 7

8 licenses for the plant. Most importantly, four +

9 consecutive times over the last two years, the NRC has O commended PG&E's outstanding safety record as part of the 10 11 Commission's semi-annual review of licensee perfcrmance -

12 in February and June 1992, and again in February and June O 13 1993. These commendations, typically referred to as the 14 NRC's "best plants" list, are among the select few awarded 15 to NRC licensees nationwide. DCPP's commendations O 16 specifically reference the excellent performance of PG&E 17 personnel and programs, and recognize DCPP as being one of the best operated nuclear plants in the nation. These NRC 18 O commendations of DCPP's overall safety performance are ,

19 20 strong indicators that DCPP's regulatory performance in 21 all areas - including maintenance and surveillance - has O 22 attained a level of excellence among the highest in the 23 United States. Copies of each of the four NRC letters 24 commending DCPP are attached as Exhibit 19.

1 b. SALP Ratings j 2 Q23 What have been the NRC SALP ratings of the DCPP 3 maintenance and surveillance programs?

i j 4 A23 (Giffin) The NRC periodically assesses the 5 programmatic performance of DCPP in key functional areas 6 such as maintenance and surveillance through the l

7 Systematic Assessment of Licensee Performance ("SALP")

3

-i 8 program. According to NRC SECY 90-189 (May 25, 1990), the 9 SALP program is an integrated NRC staff effort to  ;

10 consolidate available information to support a periodic 3

11 evaluation of a licensee's overall performance. The SALP 12 process is a means of expressing NRC senior management's j 13 observations and judgments on licensee performance. SALP 14 reviews are conducted by a SALP Board which is 15 multidisciplinary in nature. SALP reviews are intended to l

j 16 result in an integrated assessment of licensee 17 performance. SALP Board members consist of a mixture of 18 NRC regional and headquarters personnel.  ;

j 19 NRC Manual Chapter 0516 dated September 28, 1990 20 establishes the specific performance criteria applicable 21 to each functional area, and defines the 22 maintenance / surveillance functional area as including:

l 23 "

...[A]ll activities associated with either 24 diagnostic, predictive, preventive or corrective 25 maintenance of plant structures, systems, and 26 components; procurement. control, and storage of 27 components, including qualification controls; 28 installation of plant modifications; and maintenance 29 of the plant physical condition. It includes conduct

30 of all surveillance (diagnostic) testing activities as 31 well as all inservice inspection and testing 182 3

D 1 activities. Examples of activities included are instrument calibrations; equipment operability tests;

'g 2 post-maintenance, post-modification, and post-outage 3

4 testing; containment leak rate tests; special tests; 5 inservice inspection and performance tests of pumps 6 and valves; and all other inservice inspection 7 activities."

O 8 Thus, the SALP report provides PG&E - as well as the NRC -

9 with an integrated, multidisciplinary, programmatic 10 evaluation of the effectiveness of a licensee's

O performance in key functional areas, including maintenance 11

~

12 and surveillance.

13 NRC's SALP ratings have recognized the high quality 14 and effective performance of DCPP's maintenance and 15 surveillance programs. For the most recent SALP review 16 period, July 1, 1991 through December 31, 1992, the NRC lo 17 rated PG&E's performance with six "1" ratings and one "2 18 and improving" rating. The NRC rated l

19 Maintenance / Surveillance at DCPP as Category 1, the f

lO i

20 highest possible rating. Category 1 is defined as a 21 " superior level of performance" based on licensee i

[ 22 management attention and involvement in licensed l0 23 activities (NRC Manual Chapter 0516, Section 08.a). More 24 specifically, the SALP report cited the following bases

25 for its " Category 1" rating of DCPP maintenance and

'O 26 surveillance:

l 27 e Virtually trouble-free plant operation evidenced a 1

28 high quality of maintenance work; SO' 29 e The high-level of management involvement in scheduling 30 and planning maintenance and surveillance work 31 maximized safety system availability; O 183

l I

O ,

I e Maintenance and surveillance work was generally of 2 high quality; ,

3

  • The training and qualification program for maintenance 4 personnel was strong;  ;

'O 5

  • Management of outages was marked by an overriding 6 understanding and emphasis of the risk of each job.  !

7 Work crews and planners were trained and aware of the O 8 safety significance of the jobs and systems on which 9 they worked; 10

  • Work items were well prioritized, with safety-11 significant issues given high priority. Backlog of 12 non-outage safety related work was low; 13
  • The involvement and leadership shown by maintenance 14 staff in root cause investigations was a significant 15 strength, as was the integration of maintenance, 16 operations and engineering staff in maintenance and 17 surveillance activities; r

18

  • The number of personnel errors was reduced due to the 19 high level of management involvement throughout the -

O 20 organization; and 21

  • The maintenance staff overall improved their response i

22 to problems by identifying, anhayzing and correcting i

~O 23 maintenance and surveillance problems promptly. l 24 The SALP report cited four Level IV violations that had i 25 occurred in the maintenance / surveillance area, but i 26 concluded that the concerns associated with each appeared 27 to have been isolated. Some additional minor weaknesses 28 were noted as having occurred early in the SALP assessment

,0 l 184 t

1

l l

l 1 period. However, the SALP report stated that most had 2 been identified by PG&E immediately upon occurrence, and ,

3 PG&E management involvement was effective in promptly and 4 appropriately correcting the problems. A copy of the SALP

) 5 report is attached as Exhibit 20. ,

6 Previous SALP evaluations also have recognized the r

7 effectiveness of DCPP's maintenance and surveillance

) 8 programs from an overall perspective. The NRC judged 9 DCPP's performance in maintenance / surveillance to be 10 Category 2 (a " good level of performance") in each of the

) 11. three SALP assessment periods spanning August 1987 through i

12 June 1991. It is importan,t to note that every SALP 13 evaluation, including those in which PG&E's  ;

) 14 maintenance / surveillance programs have been rated " good" 15 or " superior," contains qualitative assessments of various 16 individual weaknesses and strengths exhibited within the

) 17 particular functional area during the assessment period.

18 This " feedback" from the regulators is subject tc the same 19 formal followup evaluation and corrective action by PG&E

) 20 management as internal problem reports. PG&E maintenance.

21 and surveillance management track each item to closure to 22 assure that corrective actions have been implemented in 23 response to the SALP findings.

24 The SALP ratings and NRC "best plants" list also must 25 be considered in the context of the entire nuclear 26 industry. DCPP's current SALP "1" rating in i

27 maintenance / surveillance places it high among current l

l 28 licensees in that functional area. DCPP is one of only 185 i  !

l- i

I l i

1 five plants nationwide which was commended by the NRC in

) 2 June 1993 for its overall superior safety performance.

3 This indicates that, in terms of overall regulatory 4 performance, DCPP's maintenance and surveillance program

)

t 5 is at a very high level when " benchmarked" against its '

6 peers in the industry.

D 7 2. NRC Inspection and Enforcement Activities 8 Q24 Please discuss how NRC inspection and enforcement 9 activities evaluate DCPP's maintenance and surveillance  !

)'

! 10 programs?

i

_ 11 A24 (Giffin) Routine and special NRC inspections provide

) 12 continuous information to PG&E on specific aspects of the 13 DCPP maintenance and surveillance programs. For example, 4 14 NRC inspectors routinely review DCPP LERs.and other plant J 15 events. Open items on such events are identified in 16 monthly NRC inspection reports, and PG&E's response to 17 each open item is evaluated in a subsequent NRC inspection

. 18 report. Each LER event is fully evaluated by PG&E through -

19 root cause analysis, corrective actions and/or program t

20 improvements.

)

21 Other NRC inspections and reviews provide PG&E with {

22 in-depth NRC evaluations of important maintenance and a 23 surveillance activities and programs. Examples include:

) 24

  • NRC Inspection Report ("IR") 93-08, in which the NRC ,

i 25 reviewed the DCPP 10-year In-service Inspection

("ISI") performed during the Unit 2 fifth refueling I

26

) 186 i

s 0

1 outage, and concluded that PG&E was implementing a 0 2 comprehensive ISI program in accordance with Technical 3 Specification, ASME Code and other NRC and industry 4 requirements; O 5

  • IR 91-39, concluding that PG&E was developing an 6 aggressive, well-integrated program for assuring 7 safety-related MOV reliability under Generic Letter O 8 89-10, and at the same time noting certain areas 9 requiring further development; 10
  • IR 92-201, concluding that PG&E was implementing a 0 11 strong program for evaluating and minimizing safety 12 risks associated with maintenance activities performed 13 while certain safety systems are unavailable during O 14 refueling outages; 15
  • NRC Safety Evaluation (TAC No. M83285), dated 16 September 4, 1992, concluding that PG&E's supplemental

' O 17 reactor vessel surveillance program meets NRC 18 requirements.

19 Other NRC inspections may identify isolated areas in Q 20 PG&E's maintenance and surveillance programs which need to L

l 21 be addressed. PG&E evaluates the safety significance of l

l 22 major items, performs a formal root cause analysis, and

.D implements corrective actions to avoid recurrence.

23 24 Based on a review of thousands of hours of NRC 25 inspection and enforcement activities, and hundreds of 9

26 pages of NRC inspection reports issued over the last two 27 SALP assessment periods, PG&E believes that the regulatory 187

[7

I 1 performance of DCPP's maintenance and surveillance 2 programs has been excellent.

3 III. CONCLUSION

)

4 Q25 Based on the content, performance and history of 5 PGEE's maintenance and surveillance programs for DCPP, are

)

6 the programs sufficiently effective and comprehensive to 7 assure that the public health and safety is protected if 8 PG&E is granted a full 40-year operating license for DCPP 9 as requested by the license amendment at issue in this 10 proceeding?

)

11 A25 (All) Yes.

12 Q26 Does this conclude your testimony?

ATTN: Document Control Desk g Washington, D.C. 20555 Re: Docket No. 50-275, OL-DPR-80 .;

Docket No. 50-323, OL-DPR-82 i Diablo Canyon Units 1 and 2 License Amendment Request 92-04 0 40-Year Operating License Application Gentlemen:

Pacific Gas and Electric Company applies for an amendment to Facility Operating i O License Nos. DPR-80 and DPR-82 to change the expiration dates of the full-power ';

licenses for Diablo Canyon Units 1 and 2. TG&E's enclosed request would change l' the expiration date for the Unit 1 Operating License from April 23,2008, to September 22,2021, and the expiration date for the Umt 2 Operating License from December 9,2010, to April 26,2025. These proposed expiration dates would allow-9 for 40 years of operation as permitted by 10 CFR 50.51.

The present operating license terms for Diablo Canyon are based on the NRC policy in effect prior to the 1982 determination by the Commission that the 40-year term of operation may begin upon issuance of tae first operating license, rather than upon .

issuance of the construction permit. Therefore, the present operating license terms .

g for.Diablo Canyon commence with the dates ofissuance of the construcFon permits for Units 1 and 2, April 23,1968, and December 9,1970, respectively. .

Accordingly, the expiration date for the Unit 1 Operating License is April 23 2008, and the expiration date for the Unit 2 Operating License is December 9,2010.

O Since 1982, the Commission has accepted and approved requests to amend exiving operating licenses to change the expiration dates and recover the time between the effective dates of the construction permit and the first operating license. More than 50 such license amendments have been granted by the Comenission. Based on the enclosed request, the proposed 40 year term start dates for Diablo Canyon are -

3 September 22,1981, for Unit I and April 26,1985, for Unit 2, which correspond to  ;

the effective dates of the fuel-load / low-power operating licenses for each unit.-

The proposed license term changes do not affect the design, operation, or Technical Specifications of the plant. Based on a review of the Diablo Canyon Final Safety g Analysis Report Update and the associated NRC Safety Evaluation Report and ,

Supplements, PG&E concludes that the proposed changes do not involve significant hazard considerations.

. ATTACHMENT A DIABLO CANYON POWER PLANT UNITS 1 AND 2 40-YEAR OPERATING LICENSE APPLICATION D

1.0 DESCRIPTION

OF AMENDMENT REQUEST This license amendment request (LAR) proposes to revise LI:ense Condition 2.I, " Term of License," in the Diablo Canyon Power Plant (DCPP) Units 1 and 2 Operating Licenses.

The proposed amendment would change the expiration date for the Unit i Operating License DPR 80 from April 23,2008, to September 22,2021, and change the expiration date for the Unit 2 Operating License DPR-82 from December 9,2010, to April 26,2025.

3 Marked-up pages from the licenses are included in Attachment B.

2.0 BACKGROUND

Both the Atomic Energy Act of 1954 and NRC regulations authorize issuance of facility operating licenses 3 for a pericd of up to 40 years. Commencement of the 40-year period from the date ofissuance of the operating license is allowed by 10 CFR 50.51, which states in pan: *Where the operation of a facility is involved the Commission will issue the license for the. term requested by the applicmt or for the estimated useful life of the fa:ility if the Commission determines that the estimated useful life is less than the term requested.* The NRC has established that requests for operation for a 40-yer term from.the 3 date ofissuance of the first operating license may be granted, provided the utility demonstrates reasonable assurance of safety during 40-year fa:ility operation and that the environmental effects of 40-year operation are evaluated in the Environmental Report.

Operating licenses were issued for a term of 40 years starting from the effective date of the construction permit for plants licensed prior to 1982. Beginning in 1982, however, the NRC's policy has been to 3 issue operating licenses for a 40-year term commencing with the effective date of the first operating li:ense. This revised policy in:ludes not only newly licensed plants, but also earlier plants that may apply for amendments to their operating licenses to change the license expiration date to 40 years from the effective date of the operating license.

3 DCPP Units 1 and 2 are currently licensed for 40 years commencing with the effective dates of the constru; tion permits on April 23,1968, and December 9,1970, respectively. Thus, the Unit I license expires at midnight on April 23,2008, and the Unit 2 license expires at midnight on December 9,2010.

This LAR proposes that the 40-year license terms, as permitted by 10 CFR 50.51, begin from the effective dates of the Unit I and Unit 2 first operating licenses. The initial fuel-load / low-power operating D license for Unit I was effective on September 22,1981, and the initial fuel-load / low-power operating license for Unit 2 was effective on April 26,1985. Thus, the proposed license term expiration dates would be September 22,2021, for Unit I and April 26. 2025, for Unit 2.

!* 3.0 JUSTIFICATION PG&E has assessed the safety aspects of plant design and operation of each DCPP unit for the proposed 40-year operation. Based on this assessment, as provided in Section 4.0 of this atta:hment, PG&E Ig concludes that plant safety will be maintained during the 40-year operation. This conclusion is supported ,

by the following factors (1) the DCPP facility has been designed and analyzed for at least 40 years of ,

operation; (2) the equipment, structures, and materials were purchased or constructed based on operation l of at least 40 years; and (3) inspection and maintenance programs were developed to be applicable for at least 40 years of plant operation.

O PG&E has reviewed the Diablo Canyon Final Environmental Statement and Addendum and the Environmental Repon and its Supplements to ensure that 40-year operation of each unit, commencing  ;

with the effective date of the operating licenses, is consistent with the previously evaluated environmental effects. The results indicate that no additional significant environmental impacts beyond those originally addressed are involved with 40-year operation. A summary of the environmental evaluation is provided in Secti n 5.0 of this attachment.

O PG&E has also performed an assessment of the potential impact on histori properties in accordance with Section 106 of the Histori a1 Preservation Act of 1966, as amended, and in accordance with the provisions of 36 CFR 800, Protection of Historic and Cultural Properties. No signi0: ant impa:t on histori properties was identified that could be asso:iated with the proposed license term changes.

O Benefits expected from the additional period of operation include: (1) continued availability of reliable baseload generation, (2) avoided increase in electric rates to consumers, (3) avoided air emissions, and  !

(4) continued benefits to the state and local area economy. Each of these benefits is briefly summarized -

below.

O ,

3.1 BASELOAD GENERATION L

Diablo Canyon provides baseload generation to consumers throughout Northern and Central Califorma.

The plant has prode:ed approximately 100 billion kilowatt hours (kWh) of ele:tricity since beginning  ;

O commercial operation in 1985 and is one of the most reliable nuclear power facilities in the country, with a lifetire capacity fa: tor of approximately 77 percent. Accordingly, it is prudent and beneficial to keep i this whable source of power in operation, parti ularly in light of the projected growth of California's ele.triaty demand.

In 1990, PG&E's ele:tricity demand was more than 85 billion kWh. It is expected to grow through

.O 2025. The California Energy Commission in 1992 adopted a new forecast for the PG&E service area L under which electricity demand is projected to in:rease at the rate of about 1.5 percent compounded annually through 2011. Assuming the demand for electricity continues to increase at a 1.5 percent per year rate, the overall increase in demand (1990 to 2025) would be 57 billion kWh or 65 percent. For comparison, in the period 1980-1990, PG&E's actual electri ity demand grew at an annual rate of about '

O 2.6 percent.

Given the projected electricity demand and associated increased capacity requirements through 2025, the construction of some new centralized power plants will probably be required, even assuming the term of

( Diablo Canyon's operating licenses are changed as requested in this LAR. Early retirement of Diablo

! Canyon would significantly exacerbate su:h requirements. Therefore, continued availability of Diablo O Canyon will be of substantial benefit to Northern and Central California.

540SS 'E5K y O ,

i i

)

3.2 ELECTRIC RATES In addition to providing reliable baseload generation, Diablo Canyon power costs to the customer are l

) anticipated to be competitive with PG&E's overall production costs by 2008. After 2008, Diablo Canyon costs are currently estimated to increase at less than the rate ofinflation or otherwise be competitive with new power plant costs. If the plant is not operated beyond 2008, it is likely that it will be necessary to ,

construct new baseload capacity. Accordingly, by current estimates, continued operation of Diablo Canyon through the proposed license terms would reduce future electric rate increases.

l

)

3.3 AIR E5flSSIONS '

Substantial reduction in air emissions would result from the proposed amendment because the air  !

emissions from natural gas or other fossil-fired replacement power source to replace a prematurely closed -

)

Diablo Canyon would be greater than from Diablo Canyon. If PG&E were to operate a gas-fired  ;

generator instead of Diablo Canyon, an additional annual emission of approximately 14 billion pounds of carbon dioxide,2.5 million pounds of nitrogen oxides, and 70,000 pounds of sulfur-dioxide would ,

occur. Continued operation of Diablo Canyon will avoid these emissions.

) 3.4 STATE AND LOCAL ECONO 51Y The Diablo Canyon plant is the largest private employer and tu source in San Luis Obispo County, California. This prominence is expected to continue through 2025. PG&E fully recognizes its role as a major economic base for the community. Currently, annual propeny and related taxes on Diablo

) Canyon total about 560 million. The majority of these tax revenues goes to San Luis Obispo County and represents about 25 percent of the total county propeny tax collections. The remainder is distributed throughout the rest of the state of California, where it represents about 0.2 percent of the total state propeny tax collections. PG&E currently estimates that Diablo Canyon propeny taxes will remain substantial throughout the operational lifetime of the plant.

) Equally imponant, Diablo Canyon expends approximately 5100 million annually for vendor goods and {

services. The plant has over 1,500 full-time employees as well as 500 contract employees on a ,

year ,d basis with an annual payroll of approximately 5190 million. During refueling ouages, which

~

occur approximately every 18 months for each unit. nearly 1,000 additional contract personnel are employed.

)

These benefits are anticipated to continue through the propbsed license terms.

I ,

4.0 SAFETY EVALUATION 4.I INTRODUCTION The purpose of this safety evaluation is to determine whether the proposed 40-year operating license terms would adversely affect the health and safety of the public. Most of the information that follows summarizes existing programs and activities that have been previously approved or provided to the NRC.

1 540SS/E5K 3 l I

) .

Section 4.2 reviews documents and programs that assure continued safety through the operating lifetime of the plant. Section 4.3 summarizes the plant performance and safety record during the initial 7 years of operation. Finally, Section 4.4 reviews the assurances for continued functional capability of safety-related components, systems, and structures through at least 40 years of plant operation.

D These activities and programs provide assurance that continued operation for a 40-year term will be consistent with protection of the health and safety of the public.

4.2 LICENSING BASIS DOCUMENTS / PROGRAMS J

4.2.1 FSAR and Technical Specifications "Ihe Diablo Canyon Final Safety Analysis Report (FSAR) was originally submitted to the NRC (then AEC) in September 1973 to suppon the operating license applications for Units I and 2. The FSAR included facility and system design descriptions, site characteristics, analyses of design basis accidents, and descriptions of plant operations. The NRC review of the FSAR was documented in a Safety Evaluation Repon (SER) issued in October 1974 and SER Supplements I through 34 issued periodically through June 1991. In 1984, a major update of the FSAR (termed the FSAR Update) was submitted to the NRC in accordance with 10 CFR 30.71(e). The FSAR Update is revised annually to reflect changes in plant design, evaluations, and analyses. The latest revision (Revision 7) was submitted to the NRC D in September 1991.

Separate Technical Specifications were issued for Unit 1 'in 1981 and 1984 and for Unit 2 in 1985.

Subsequently, combined Technical Specifications applicable to Units I and 2 were issued in August 1985 l- as Appendix A to the operating licenses. Since that time, PG&E has implemented a comprehensive Technical Specification Improvement Program for Diablo Canyon designed to reduce the likelihood of r reactor trips and forced outages, while maintaining a high level of operational safety. The program l invohes evaluation of plant systems and operations to identify desired improvements to individual i Technical Specifications. The improvements have included eliminating unnecessary on-line testing, I increasing surveillance test intervals for enuipment, revising tolerances and serpoints, eliminating or L relocating unnecessary specifications, supponing plant betterment design changes, and allowing use of 3 improved fuel designs To date, over 60 amendments to the Technical Specifications have been requested 1- and issued.

4.2.2 Probabilistic Risk Assessment The Diablo Canyon probabilistic risk assessment (DCPRA) is a full scope, Level I risk assessment. It has recently been updated and extended to a Level 2 assessment addressing Individual Plant Examination (IPE) requirements, as specified in Generic Letter 88-20 and NUREG-1335.

I In addition to using the DCPRA to meet IPE requirements, the DCPRA is used, as appropriate, for other p goals and objectives, such as to:

  • SupponTechnical Specification changes, especially changes to allowed outage times and surveillance test imervals
  • Evaluate continued plant operation under nancoriformini conditions by quantifying effects on plant

)- risk 540SS/S5K 4

)

)

  • Evaluate certain proposed design changes that are intended to improve plant safety or reliability
  • Provide insights to the Training Department for use in developing operator training plans ,

) For these applications, it is necessary to maintain an up-to-date PRA. Thus, a process has been I developed and implemented to update the DCPRA on a periodic basis (every 18 months) to ensure it represents the current plant configuration. The update process will include revisions to:

  • DCPP-specific initiating event data
  • DCPP component failure rate data
  • DCPP maintenan:e duration and frequency data
  • DCPRA models and databases based on a review of DCPP design changes and plant procedure 3 changes In summary, the DCPRA wi!! be used to continually enhance and improve operation throughout the proposed 40-year operating license terms.

D 4.2.3 Surveillance and Maintenance Programs In accordance with the Technical Specificatios and the requirements of Title 10 of the Code of Federal Regulations, Diablo Canyon has established programs for maintenance and surveillance of safety-related equipment. These programs include the Inservi:e Inspection OSI) Program, Inservice Testing OST)

) Program, Environmental Qualification (EQ) Program, and Maintenance Program. These programs assure that any significant degradation of plant equipment will be promptly idcntified and corrected throughout the proposed 40-year operating Isense terms.

D 4.2.3.1 ISI and IST Programs The Diablo Canyon ISI and IST Programs were initiated in 1985 for Unit I and 1986 for Unit 2, corresponding to the start of commercial operation of each unit. The ISI and IST Programs comply with the requirements of 10 CFR 50.55a(b)(2) and 50.55a(g). The ISI and IST Programs also comply with the requirements in the Diablo Canyon Technical Specifications. The ISI and IST Programs include j inspection, testing, and maintenance of pressure-retaining components (including their support structures) as required by the American Society of Me:hanical Engineers Boiler and Pressure Vessel (ASME B&PV)

Code for Class 1,2, and 3 systems. Components that are within the scope of the IST Program are Class 1,2, and 3 pumps and valves that are required to perform a specific function in shutting down the reactor j

or mitigating the consequences of an accident.

)

! As part of the inservice inspection effort, a Preservice Inspection (PSI) Program for Class 1,2, and 3 l systems was conducted on Unit I which, to the extent practicable, complied with the requirements of

! ASME B&PV Code, Section XI,1974 Edition including the Summer 1975 Addenda. For the PSI piping examinations, the examination technique of Appendix 111 and the acceptance criteria ofIWB-3514, both from the Winter 1975 Addenda of the ASME B&PV Code, Section XI, were used. For Unit 2, a PSI h Program for Class 1,2, and 3 systems was conducted which, to the extent practicable, complied with the requirements of ASME B&PV Code, Se: tion XI,1977 Edition including the Summer 1978 Addenda.

540ESIS5K 5

/

).

The first 10-year inspection interval, which began in 1985 for Unit I and 1986 for Unit 2, meets the requirements of the ASME B&PV Cnde Section XI,1977 Edition including the Summer 1978 Addenda.

When examination techniques differ due to code changes between the PSI and ISI examinations, the ISI exarination data are used as the new baseline.

) ne ISI Program in !udes visual, surfa:e, and volumetric examinations. De surface examinations are done with the liquid penetrant or magnetic particle methods. The volumetric examinations are done using the ultrasonic or radiographi examination methods. De objectives of these examinations are to: ,

  • Identify unexpected service-induced component degradation, which would be evidenced by surface

) cracks, wear, corrosion, or erosion e Ixcate any evidence of componer t leakage during system pressure or functional tests

  • Verify operability of components and integrity of component supports

) Records of inspections completed under the ISI Program are kept in accordance with the requirements of ANSI Standard N45.2.9 and ASME Section XI and are transmitted to the NRC following each inspection. ,

"' m" 50 55a(g) requires revL;on of the ISI and IST Programs as necessary to comply (to the extent

) pr . ._ . man the limitations of design, geometry, and materials for construction of componenu) with .

the edition of the ASME B&PV Code and Addenda in effect and adopted by the NRC 12 months prior to the start of each 10-year inspection interval. These programs ensure that pressure-retaining ,

components will be adequately inspected, tested, and maintained throughout the proposed 40-year operating license terms. .

)

4.2.3.2 EQ Program j Environmental qualification (EQ) is a rigorous program of testing, analysis, and maintenance to confirm [

that electri: equipment relied on in the event of an accident will be capable of performing its design safety l'

) function, despite exposure to the harsh environment resulting from the a:cident.

The EQ Program for DCPP complies with the requirements of 10 CFR 50.49,

  • Environmental Qualification of Electri: Equipment Important to Safety for Nuclear Power Plants.* As applied to DCPP, 10 CFR 50.49 requires that electric equipment important to safety and located in a harsh environment  :

be environmentally qualified, at a minimum, in accordance with IEEE Trial-Use Standard 323-1971 and

) the Category Il positions in NUREG-0588 ("For Comment

  • version, dated December 1979). [

In accordance with 10 CFR 50.49 (1), replacement equipment (for equipment that is required to be environmentally qualified) is required to be qualified in accordance with IEEE Standard 3231974 and i the Category I positions in NUREG-0588 (*For Comment

  • version, dated December 1979), unless there are sound reasons to the contrary, ne DCPP EQ Program is a continuing program. The master list of equipment required to be qualified  ;

is maintained as a controlled engineering drawing and is revised as plant design changes are implemented.

Detailed EQ files do:ument the results of the testing and analyses that substantiate that the equipment will perform as required in accident environments. Surveillance activities are performed to detect adverse  !

) trends in aging or performance. Maintenan:e procedures assure that the qualified configuration of i

540SS/S5K 6 i

)

3 equipment is restored after maintenan;e. Equipment that is not designed for the entire 40-year operating license terms is refurbished or repla:ed prior to exceeding its qualified life.

Supplements 15 (dated September 1981) and 31 (dated April 1985) to the Diablo Canyon Safety D Evaluation Report (SER) provide the NRC Staffs evaluation of the Diablo Canyon EQ Program. In Supplement 31 to the SER, the Staff concluded that the Diablo Canyon EQ Program is acceptable and that complian:e with 10 CFR 50.49 has been demonstrated. Supplement 31 also noted that the EQ program had been expanded to in !ude Regulatory Guide 1.97 Category 1 and 2 instrumentation. The NRC Staffs findings were premised on the continuing nature of the Diablo Canyon EQ Program (e.g.,

g replacement of equipment prior to expiration ofits qualified life), without regard to the remaining license period. Thus, no Staff findings regarding the adequa:y of the EQ Program are altered by this amendment request.

In summary, the EQ Program ensures that electric equipment important to safety within the scope of 10 CFR 50.49 will be adequately qua!ified and maintained, and thus capable of performing required O safety functions throughout the proposed 40-year operating license terms.

4.2.3.3 Maintenance Program Maintenance is the integrated means of maintaining the plant material condition throughout its 40-year operating life. It consists of those maintenance, surveillan:e, engineering, and operations activities necessary to control normal degradation that o::urs with time and use.

PG&E has developed and implemented comprehensive programs to manage the effect of aging and service wear on Diablo Canyon's systems, stru:tures, and components (SSCs) throughout the 40-year operating 3 life of the plant. The programs provide the methods for inspection, surveillance, and monitoring of the plant to detect aging effects before the loss of system function and to effect maintenance and component replacement practices for mitigating the effects of degradation.

It is recognized that SSCs can deteriorate as the service life of the plant increases. This recognition forms

, the basis for regulatory requirements, industry codes and standards, and the development of PG&E's

~#

Maintenan:e Program and its component categories. Design features have been incorporated into Diablo Canyon that provide the ability to test, inspect, and perform preventive and corrective maintenan:e on these SSCs. As a reait. Maintenan:e Program pra:tices provide assuran:e that any unexpected degradation in plant equipment will be identified and corrected.

3 The Maintenance Program was developed with the underlying philosophy that it is necessary to have the requisite administrative and technical controls to ensure that maintenance is performed in a timely and safe manner consistent with applicable license and quality control criteria. This philosophy is important a the purpose of the Maintenan e Program is to maintain the continued functionality and safe operational performan:e of all plant equipment throughout the 40-year operating life.

O The Maintenan:e Program is implemented through procedures developed in conjunction with the Diablo Canyon Quality Assurance Program and PG&E's operational philosophy. These procedures incorporat:

relevant information from the Technical Specifications, design basis criteria, and NRC Safety Evaluation Reports. They provide means to monitcr, inspect, maintain, and test plant SSCs in a programmati:

! manner O

Maintenance tasks are categorized as preventive maintenance or corrective maintenance. Preventive and corrective maintenance tasks were identified and initiated during the construction phase by PG&E General  :

Construction personnel. Maintenance continuity has been maintained throughout the construction phase, system turnover to plant staff. *he period from operational testing through the stan of commercial perati n, and during commercia operation.

O Maintenan:e tasks for equipment (and systems) are largely based on the applicable manufacturer maintenance recommendations, applicable industry standards and experien:e, plant maintenance history, and PG&E experience. Additionally, Westinghouse (the manufacturer of most major plant components) was present onsite during the construction phase and has provided preventive maintenance information 0 and guidelines for the Nuclear Steam Supply System equipment it supplied. The Westinghouse guidelines include recommended chemistry controls and system layup conditions.

In addition to procedural guidance on specific maintenance activities, maintenance procedure's also provide '

for scheduling, implementing, and documenting activities covered by the Maintenance Program. PG&E installed a computer-based Plant Information Management System (PIMS) prior to the stan of commercial O operations to assist plant maintenance and engineering personnel in there 1ctivities. PG&E also committed additional resources to develop state-of-the-art machine shops, maintenance training facilities (which in:lude extensive laboratories for training technicians), spare parts inventories, and management svstems. Staff resources and personnel training are provided to fully implement and use these suppon resources.

O  !

De 151, IST, and EQ Programs, discussed in Sections 4.2.3.1 and 4.2.3.2, are integral parts of the l Mainoan:e Program. Interdisciplinary activities in the areas of surveillan:e, engineering, and operations, along with a description of program enhancements, are presented below.

Surveillance and Predictive Maintenance O

Surveillance test prccedures (STPs) are implemented by the DCPP Maintenance Groups, Plant Engineering, Operations, Chemistry, Radiation Protection, and Plant Suppon Services groups. De STPs include those tests that are required by Technical Specifications, licenses, and other documents regulating the operation and maintenance of the plant. In addition, predictive maintenance programs include O vibration analysis, acousti: analysis, oil analysis, ferrography, thermography, and component monitoring (using both on-line and off-line performance monitoring systems).

Encineerire i Engineering is integrally involved in all aspects of the Maintenance Program. Engineering support is O integral to the maintenance process in assessing the effectiveness of maintenance, in-depth failure analysis, l

configuration control, and equipment qualification. Engineering provides the design and construction  :

suppon for plant improvements and the retirement of equipment that is degraded or approaching )

obsolescen:e. I o Engineering also provides evaluation and analysis support for SSCs with specific aging problems that are identified at the plant or through industry experien:e or research. Engineering has generated the programmatic solutions to mitigate these problems and incorporate solutions into maintenance and  ;

monitoring practices to permit management and control of the aging process to within specifications.

Plant operations is also involved in the maintenance of plant equipment. Diablo Canyon procedures and

, pra:ti es emphasize the need to control the manner in which equipment is operated as well as its environment. Equipment life is prolonged thrcugh proper control of equipment environmental factors, rigid chemistry controls, and proper equipment layup when not in service. Operational procedures have been developed to minimize the stress placed on equipment through transients and to prevent error-induced stress initiators. 06er operational pra:tices contribute to prolonging the service life of equipment such as balan ing the run time on redundant equipment, minimizing unnecessary operation,

@ and monitoring and maintaining external environmental factors including temperature, humidity, moisture, and foreign contaminants.

Enhancements to the Maintenance Procram g The Maintenan:e Program requires continual adjustment as plant-specifi: performance is evaluated, industry experien:e is gained, and new methods and technologies develop. The Maintenance Program at DCPP is a living program that has evolved continuously through the construction and operation phases.

Maintenance Program task improvements have been developed as a result of the equipment failure analysis process (root cause analysis and corrective a: tion program), component f ailure reports, evaluation of industry operating experience, and through better understanding of aginq and failure mechanisms D applicable to Diablo Canyon equipment. These program improvements are proceduralized and receive significant engineering support and evaluation.

Examples of program enhancements include:

g Predictive maintenance programs have been expanded and are managed by a dedicated staff. These programs allow greater reliance on condition monitoring to establish preventive maintenance a:tivities.

  • A Reliability Cemered Maintenance Pr) ject has been implemented to optimize the maintenan:e program and improve plant / system reliability and availability.

?

Diablo Canyon has been in commercial vperation for approximately 7 years. During this time, a  !

3 significant amount of data and experience has been accumulated that demonstrates the safety and reliability of the plant. Numerous plant modifications have also been made to improve reliability and upgrade safety-related equipment. Since beginning operation, PG&E has invested about 100 million j

do!!ars per year on an aggressive capital equipment upgrade and replacement program. Operating  !

performance, plant modifications, and regulatory performance are reviewed in the following sections. j J

4.3.1 Operating Performance The lifetime capacity factor for Diablo Canyon through its first 7 years of commercial operation is l approximately 77 percent. Achievement of reliable operating performance, in the form of a high capacity-

-l fa: tor, has always been a PG&E goal for Diablo Canyon because PG&E is convinced that high capacity  ;

3 factors are the result of a well managed, safely operated nuclear plant. Keeping refueling outages as shon  !

as possible through sound outage planning, while safely and effectively performing all necessary work, has also contributed to high capacity factors for Diablo Canyon. Overall industry experience supports 3 our conclusion that units with' consistently high capacity factors, relatively short refueling outages, and i Iow forced outage rates are well maintained, follow good operating practices, and thus can be expected {

? to operate at high levels of safety.  !

O in addition to capa:ity fa: tors, there are other performance indicators commonly used to monitor performance: unplanned automatic reactor trips, unplanned automatic safety system actuations, collective radianon exposure, significant events, safety system failures, forced outage rate, and equipment forced 8 outages /1000 critical hours. As indicated in the NRC's quarterly publication of industry performance indicators, Diablo Canyon currently compares favorably with the industry averages for these indicators.

4.3.2 Reliability / Safety-Related Plant Modifications A number of major plant modifications designed to improve reliability or upgrade safety-related equipment have been made during the 7 years since Diablo Canyon began operation. Several others are planned in the near future. Some of the more 0 mificant mc4ifications include:

  • Copper Removal - Ris project involved repla einent of all feedwater heaters and retubing of all O moisture separator reheaters. These changes resulted in the removal of essentially all copper from the secondary side of the plant to increase the life of the steam generators.
  • Condensate Polisher Addition - To further increase the life of the steam generators, Condensate Polisher System was added to process se:ondary water by ion-exchange. Regeneration of the ion-exchange resin in the condensate polisher system results in additional solid waste and liquid effluents.

g

  • Ammonium Hydroxide Storage - To regenerate condensate polisher resin, a 6,000 gallon bulk storage tank for ammonium hydroxide was added.
  • SG Blowdown Rate Increase - To improve secondary water chemistry and thus in:rease the expected O life of the steam generators, the blowdown rate has been increased.
  • Control Room Upgrade - A detailed control room design review (DCRDR) was performed in a::ordance with the requirements specified in Supplement I to NUREG-0737. Weaknesses in the man-machine interface between control room operators and equipment were identified in the DCRDR.

g Following review and approval by the NRC, control room equipment upgrades have been implememed.

  • High Density Spect Fucl Fool Racks - The original fuel ra:ks in ea:h unit's spent fuel pool were repla:ed with high density ra;ks, increasing the capa:ity in ea:h spent fuel pool from 270 to 1324 fuel assemblies.

O

  • Improved fuel Design - ne reactor fuel used in ea:h unit is being replaced with' an improved VANTAGE 5 Westinghouse design. Most of the fuel in ea:h reactor will be of the VANTAGE 5 design by early 1993.
  • Baron Injection Tank fBIT) Removal-In response to industry experien:e and NRC recommendations, g the BITS in both Diablo Canyon units were removed from service to reduce the potential for boric acid crystallization in ECCS piping and valves whi:h could potentially have degraded safety-related equipment operability.
  • Reduced Boric Acid Concentration - The baron con:entration in the Bori: Acid System has been
  1. redu:ed from 12 to 4 weight percent to reduce the pmential for boric acid crystallization in safety-related components.

  • Digital Feedwater Control System - A digital feedwater control system was installed to improve feedwater control performance and reliability. The enhanced feedwater control features provided by ,

this system reduces the likelihood of steam generator level-related reactor trips. Implementation of ' the steam generator level median signal select feature prevents interaction between *he feedwater 3 control and reactor protection systems, which allowed deletion of the low feedwater flow reactor trip  ; function.

  • Computer Replacement - ne original plant pro:ess computer was replaced with one having improved man-ma: hine interface, greater capacity, faster response time, improved print and report capability, 3 improved retrieval of historical data, and complete redundancy to prevent loss of information due to single failure.
  • A7WS Ffitigation System Actuation Circuitry (Ah! SAC) - The AMSAC System was installed in both Diablo Canyon units to ensure rea: tor protection during an anticipated transient without scram '

(A~BVS) event that results in the loss of the secondary side heat sink. AMSAC is designed to trip ) the main turbine, initiate auxiliary feedwater flow, and isolate steam generator blowdown and sample lines during an ATWS with a low steam generater level condition.

  • Chlorination System Afodifications - Modin;ations to the Chlorine System include (1) the use ofliquid hypo:hlorite to control microbiofouling instead of gaseous chlorine, (2) implementation of continuous chlorination of the auxiliary saltwater system to control macrobiofouling (invertebrate marine life),

3 and (3) possible use of intermittent injection of a chlorine / bromine mixture to prevent macrofouling in the Circulating Water System.

  • Fatigue Afonitoring - PG&E is installing an on-line fatigue monitoring system at Diablo Canyon that will continuously analyze plant operational data to tra:k fatigue usage of critical reactor coolant 3 system components.
  • Additional Diesc. (Jenerator Addition of a sixth diesel generator will provide ea:h unit witn three dedicated diesel generators. This will enhance reliability of the onsite power distribution system by eliminating dependen;e on a swing diasel generator and the associated procedural complexities.

Installation, testing, and tie in of the sixth diesel is scheduled for completion in the spring of 1993. J

  • Plant Process Protection System Upgrade - This project will upgrade the Process Prote: tion System New by repla:ing the existing HAGE.< 7100 equipment with a Westinghouse Eagle 21 system.

steamline break logi: and steam generator low-low level trip time delay options will be in:luded in the upgrade. These changes will improve the reliability and availability of the Process Protection 3 System. De digital micropro:essor-based system with computer-enhanced testing will also minimiz the likelihood of personnel error during surveillance testing. System installation is scheduled for the spring of 1994 for Unit I and the fall of 1994 for Unit 2.

  • R7D Bypass Elimination - This project will repla:e the resistance temperature detector (RTD) bypass loop piping with fast response RTDs installed in the hot and cold legs of the Reactor Coolant Syste J Plant downtime and radiation exposures will be reduced and numerous snubbers can be eliminated.

Installation is scheduled for the spring of 1994 for Unit I and the fall of 1994 for Unit 2.

  • Radiation Afonitoring System (RhfS) Upgrade - This proje:t will upgrade the present RMS to improve performan:e, reliability, and capability. Most of the work is scheduled to be completed by 19 540SS/S5K 12 3

i G 4.3.3 Regulatory Performance l The latest Systemati: Assessment of Licensee Performance (S ALP) report for Diablo Canyon covered the

  1. period of January 1990 through June 1991. The S ALP Board found the performance oflicensed activiti-at Diablo Canyon to be very good, in some cases to be superior, and clearly directed toward safe facility operation.

, 4.4 ASSURANCE OF CONTINUED FUNCTIONAL CAPABILITY OF SAFETY-RELATED COMPONENTS Assurance of an acceptable level of safety throughout the proposed 40-year operating license terms is provided by the continued functional capability of safety-related components. These are components associated with systems designed to prevent or mitigate events that could cause a release of radioa:tivity 9 to the environment. The following discussion reviews such components at Diablo Canyon. 4.4.1 Reactor Coolant System Pressure Boundary y 4.4.1.1 General The mechanical components associated with the Rea: tor Coolant System (RCS) pressure boundary include the rentor vessel, pressurizer, portions of the steam generators, piping, valve bodies, and pump casings. The design of these components incluued consideration of potential effects of age-related phenornena such as corrosion, therma! and vibration fatigue, and radiation-indu:ed embrittlement. Consideration of these O effects was also taken into account when the operating limits and surveillance requirements were established in the Technical Specifications. In accordance with the latter requirements, the RCS is included in the Inservice Inspection Program (see Se: tion 4.2.3.1). Components are located su:h that critical areas are sufficiently a essible for the required inspections and/or tests. The potential for corrosion was accounted for by using corrosion resistant materials in the design of the g plant. All mechanical components that are in conta:t with reactor coolant, except the fuel, are either made of or clad with austenitic stainless steel or nickel-based corrosion resistant alloys. The fuel is clad with Zircaloy. The RCS water chemistry is managed to minimize corrosion. Analysis of the coolant is routinely performed to verify that it meets the spe:ifications for chemistry, radioactivity level, and boron concentration. O Components of the RCS pressure boundary are designed to withstand the fatigue effects of cyclic loads due to system temperature and pressure changes. These cyclic loads are introduced by normal load transients, reactor trips, and startup and shutdown operations. During startup and shutdown, the heatup and cocidown rates are limited to less than 100*F/ hour, consistent with system design specifications and the Technical Specifications. Deviations from these conditions are evaluated to determine complian:e g with code requirements. Plant procedures provide for the ongoing collection of data relative to thermal transients. These data are compared with original design requirements to assure the adequacy of the remaining fatigue life of RCS components. PG&E is in the pro:ess of installing an online fatigue monitoring system at DCPP that will D continuously analyze plant operation data to track fatigue usage of the critical RCS components. 540SS/85K j3

1 l 3 i 4.4.1.2 Reactor Vessel i 1 De Diablo Canyon rea: tor vessels were designed and fabricated in accordance with ASME Boiler and I Pressure Vessel Code, Section III,

  • Nuclear Power Plant Components.* They were designed for  !

D transients considered to envelope design conditions over a 50-year operating period. To ensure the continued integrity of the vessels during operation, an ISI Program (see Section 4.2.3.1) has been in pla:e since plant startup. The ISI Program requires volumetri examination of each a :essible pressure boundary weld at least once in each 10 year interval. The effects of neutron radiation embrittlement of the vessel beltline region are considered in the design 3 and operation of the units. Compliance with all NRC regu:ations governing vessel integrity has been documemed recently in PG&E's response to Generi: Letter 9241 (PG&E Letter No. DCL-92-150, dated June 30,1992). In addition, PG&E has instituted an Embrittlement Management Plan to manage rea: tor vessel embrittlement throughout the entire operating life of Diablo Canyon. O Pressurized Thermal Shock Following Cy:le 1 for ea:h unit, the neutron tluence at the reactor vessel inner wall was reduced by installing increasingly lower neutron leakage cores, thus decreasing the reactor vessel rate of embrittlement and prolonging vessel life. The Diablo Canyon rea: tor psssure vessel beltline materials have been evaluated a: ording to the NRC's Pressurized Thermal Shock (PTS) screening criterion defined O in 10 CFR 50.61. The Referen:e Temperature for Pressurized Thermal Shock, RTm, has been calculated for each weld metal and base metal in the DCPP beltline regions for neutron Ouences corresponding to 40 operating years. '!he RTm for ali materials will not exceed the screening limit of 270*F for base metal and longitudinal welds and 300*F for circumferential welds. Since all materials meet the screening criterion, neither additional Dux reduction nor plant specific PTS analyses are required O to comply with the PTS rule. Details of the PTS evaluation have been submitted to the NRC (PG&E Lwr No. DCL-92-056, dated Mar:h 6,1992). Based on a conservative Cuence projection for 40 operating years, DCPP will also meet the requirements of 10 CFR 50, Appendix G. Charpy Upper Shelf Energies were determined (FSAR Update Tables 5.2-19A,5.2-19B,5.2-21 A, and 5.2-21B) in a::ordance with Regulatory Guide 1.99, Revision 2. All Diablo O Canyon beltline materials will remain above the 50 ft-lb Charpy Upper Shelf Energy fracture toughness requiremem for more than 40 operating years. In addition, reactor vessel pressure-temperature limits will meet 10 Cf R 50, Appendix G requirements for 40-year operation without requiring plant modin:ation or imposing operational restrictions. O Material Surveillance Procram The toughness properties of the rea: tor vessel beltline material will be monitored throughout the proposed 40-year operating license terms with a material surveillan:e program that meets the requirements of 10 CFR 50, Appendix H. O Re surveillan:e test program for DCPP Unit I complies with ASTM E 185-70, the standard in effe:t ) when the vessel was manufa:tured. Although the Unit I surveillance program was designed prior to the j existence of 10 CFR 50, Appendix H, it does contain the significant features required for later I surveillance programs and will effectively monitor vessel embrittlement throughout the requested license period. The program in:!udes a total of eight surveillance capsules. Three of the eight capsules contain p the limiting weld metal and base metal, correlation monitor material, dosimeters, and thermal monitors. 540SS/S5K 14 0 1

Nevertheless, such components are included in the plant ISI and Maintenance Programs, so I that any unexpected degradation will be identified and corrected should it occur. Many of the active (moving or rotating) me:hanical components, such as pumps and valves, are expected to wear and are ) therefore periodically tested and maintained under the IST and Maintenance Programs. Degradation of these components will therefore be identified ant. corrected, and component functional capability will be F maintained. In summary, passive mechanical componerIs tre designed such that they are not expected to be replaced over the 40-year operating license terms, d 41e the functional capability of active components will bc ) maintained through inservice testing, mtinter .nce, and/or periedic replacement. 4.4.3 Electrical Components * ) Electrical components that are required to function in a harsh environment (significantly more severe than the environment that would occur during normal plant operation, including anticipated operational , occurrences) during a design basis event are covered by the EQ Program. The EQ Program complies with the requirements of 10 CFR 50.49, as discussed in Section 4.2.3.2. Safety-related electrical equipment at Diablo Canyon that is not covered by the EQ Program is covered 3 by the plant Maintenance Program (Section 4.2.3.3). As required by the Technical Specifications, equipment is tested periodi: ally in a::ordan:e with surveillan:e test procedures. Equipment is repla:ed as required. 4.4.4 Structural Components 4.4.4.1 Primary Containment , The structural integrity of Diablo Canyon'* containment steel liner, the concrete shell, and internal l concrete and steel structures is assured for a 40. year operating period for the following reasons: )

  • The containment liner, the con: rete shell, and internal concrete and steel structures were designed and constructed in a: ordance with Amerien Concrete Institute (ACI), American Institute of Steel Constru: tion (AISC), and ASME Section Vlli Codes to withstand a:cident load combinations, including postulated seismic and loss-of-coolant accident events. Rese load combinations have resulted in much stronger primary containment structures than required to support normal operating h loads.

  • Construction was carried out in accordance with strict construction and quality control procedures.

Actual material testing results indicate a high level of quality in construction techniques and materials used to construct the containment structure. For example, the concrete strength tests for the containment structure indi: ate that the in-situ concrete strength is approximately 25 percent higher than the nominal design values used in the design calculations.

  • Through the first 7 years of operation at Diablo Canyon, minor maintenance to concrete surfaces and ,

protective coatings has been performed to ensure the continued structural integrity of the primary j containment. The need for this work has been detected through the following actions

The inspection and documentation process is designed to detect unacceptable concrete cracking, concrete spalling, or deterioration of protective coatings. Repairs are made as needed. Root cause evaluations are performed as required to ensure other potential problem areas are addressed.

  • A review of the performance of other principal concrete structures in the U.S. nuclear industry has not yielded experience data that would indicate an adverse impact on the structural integrity of the primary containment for the proposed 40-year operating license terms.

  • Construction was carried out in a:cordance with strict construction and quality control procedures.

Actual material testing results indicate a high level of quality in construction te:hniques and materials 3 used to construct these structures.

  • These plant structures and associated protective coatings are periodically inspected and maintained to ensure continued stru:tural integrity. Through the first 7 years of operation, the intake structure has been the only concrete structure to show some degradition. An evaluation by PG&E showed that 3

minor refurbishment would restore the intake to its original condition. The intake structure is currently being refurbuhed to ensure its continued structural integrity. In addition, PG&E is enhancing marine inspe: tion and repair procedures to better preserve the integrity and serviceability

i ) 5.0 ENVIRONMENTAL EVALUATION

5.1 INTRODUCTION

l PC, 2 has reviewed and assessed information contained in the " Final Environmental Statement related ) to the Nuclear Generating Station, Diablo Canyon Units 1 and 2" (FES) and Addendum, the Environmental Report and the eight Supplemental Environmental Reports, the Final Safety Analysis Report Update, and other studies and data accumulated over the past years of operation to ensure l thorough and complete evaluation of potential environmental issues related to the proposed 40-year operating license terms. The environmental evaluation is divided into six additional sections. In Section 5.2, systems and programs for environmental control and monitoring are evaluated to ensure they meet applicable regulatory criteria and show evidence of continued enhancement and effectiveness. The systems and programs evaluated in:!ude the Waste Processing System, ALARA Program, Process and Area Radiation Monitoring System, Radiological Environmental Monitoring Program, and Nonradiological Surveillan:e - ) Program. Section 5.3 presents an assessment of the environmental effects of plant operation during the proposed 40-year license terms to ensure they remain within the bounds of the FES and applicable regulatory criteria and permits, or where appropriate, upper iimits estab'ished from plant operation to date. Topics ) addressed include occupational and offsite radiation exposures, new fuel requirements and spent fuel storage, generation and transponation of spent fuel and other wastes, thermal and ecological effects of the cooling water system, and the poterti9 impact on histori properties. Section 5.4 considers the offsite exposures from releases during postulated accidents. These exposures were previously evaluated in the original FS AR (presently the FSAR Update) where the results were ) found to be within the guideline values in 10 CFR 100. Using projected population size and distribution in the vicinity of the plant for the roposed 40-year operating license terms, it is shora that 10 CFR 100 criteria will continue to be met. L De potential effects of population in:reases on emergency planning are evaluated in Section 5.5, and ) Section 5.6 summarizes the plant modi 0 cations that are environmentally related. Also, the effe:ts of the proposed 40-year operating license terms on decommissioning are evaluated in Section 5.7. t 5.2 SYSTE51S AND PROGRASIS FOR ENVIRONh1 ENTAL CONTROL AND MONITORING ) 5.2.1 Waste Processing System The Waste Pro:essing System is described in Chapter 11 of the FSAR Update. His system, which has been significantly upgraded since the original design, receives, processes, and safely discharges or ) packages radioactive waste for funher offsite processing or disposal. The basic processes used are decay of radioactive isotopes, particulate filtration, selective ion exchange, dewatering or solidation of wet waste, filtration of gases by HEPA filters, release of low activity wastes, and compa: tion of dry active waste. As described in the FSAR Update, the system consists of components such as liquid and gas storage tanks, pumps, compressors, filters, ion exchange vessels, instruments, piping, and valves.

3 Efnuent releases from the Waste Processing System have always remained well below the liraits contained in the Te:hnical Spe:in:ations, and within the range projected in the Final Environmertal Statement. System performance is monitored, and design and operational enhancements have ben made, where " feasible, to minine efnuent releases. Some examples of enhancements include optimizing the ion exchange resins ano 61ter pore sizes, modifying the spent resin storage tanks, and processing waste more frequently and to lower activity levels. A summary of the quantities of radioactive liquid and gaseous efCuents and solid waste released from the plant is reported to the NRC in the Semiannual Radioactive Efnuent Release Report. O This system will continue to be used throughout the proposed 40-year operating license terms to ensure wastes are safely and effectively processed. 5.2.2 ALARA Program 3 PG&E's management is strongly committed to maintaining personnel exposures to ionizing radiation at DCPP as low as is reasonably achievable (ALARA). As a result of this commitment, a formal organization has been established to review, evaluate, and re:ommend ALARA actions for all radiological work at DCPP. PG&E has established a goal to maintain the performance indicator of plant collective radiation exposure, in person-rem per year, to be within the Institute of Nuclear Power Operations 3 (ISPO) guidennes. Occup-ional exposures resulting from the proposed 40-year operating license terms will remain within the lists of 10 CFR 20. The DCPP ALARA Prcgram established in response to the requirements of 10 CFR 20.l(c) will contribute, in large part, to minimizing the already low levels of occupational exposure at the plant. O. Diablo Canyon's ALARA Program requires that an estimate of the total dose be provided for all Radiation Work Permits (RWPs). If the estimate is less than 1 person-rem, the ALARA controls are established by the person initiating the RWP. If the estimated total dose is at least I person-rem but less than 10 person rem, the job receives an ALARA review by the Radiation Prote: tion Work Planning 3 Group. All jobs estimated at 10 person-rem or greater require an ALARA review by the Radiation Protection Engineering Group prior to thejob being initiated. Jobs estimated at 25 person-rem or greater, or an indnidual dose of I rem or greater, require additional review and approval by the plant ALARA Committee. s The Plant Staff Review Comminee (PSRC) serves as the plant ALARA Comminee, and is composed of personnel from the various Diablo Canyon departments. A separate group, the Joint ALARA Review Comminee (JARC), comprised of Diablo Canyon and corporate management, meets periodically to assess the effectiveness of exposure control methods in keeping personnel exposures ALARA. Furthermore, the JARC assists in developing ALARA policy and procedures, and monitors the implementation of ALARA measures. D The ALARA Program is assessed after each outage in a report that lists exposures incurred on majorjobs and summarizes the ALARA lessons learned for future reference and application. De report allows the JARC to identify ALARA-related inadequacies in designs or pro:edures used for equipment installation, operation, surveillance, and maintenance. The results of these post-job critiques provide knowledge that can be used to improve designs and reduce exposures on the same or similar jobs in the future. $ Similarly, Diablo Canyon a!so sets an annual plant exposure goal based on the outage report and input 540SS/85K 19 3

5.2.3 Process and Area Radiation Monitoring System  ; The Process and Area Radiation Monitoring System is described in Chapter 11 of the FSAR Update.  ;

)

This system monitors radiation levels associated with process systems and areas at various locations in the containment and in the auxiliary and turbine buildings. It is designed for use during normal operation or postulated accident situations and includes equipment' for detecting, computing, indicating, and  ! alarming. Periodic testing and inspection of the system assure its functional readiness. l

5.2.4 Radiological Ensironmental Monitoring Program 1

)                 The Radiological Environmental Monitoring Program is described in Chapter 11 of the FSAR Update.

The program was established prior to the start of plant operation to determine preoperational background _ i levels. The Radiological Environmental Monitoring Program is designed to validate the adequacy of - i j safeguards inherent in plant design and the effectiveness of dose calculations, based on plant emission data and appropriate meteorological and aquatic dispersion models. Emphasis is placed on control at the 1 source, with follow up and confirmation by environmental surveillance. This is accomplished by.

  ).               continuously measuring radiation levels and airborne radioactivity levels and periodically measuring amounts of radioactivity in samples at various locations surrounding the plant. Results from the.

Radiological Environmental Monitoring Program are reported to the NRC in the Annual Radiological Environmental Operating Report. The several types of sample media used correspond to the possible exposure pathways. These pathways

  )                 are direct radiation, inhalation, and waterborne or airborne ingestion. Direct radiation is measured 540SS/S5K                                                20
  )

O continuously by thermoluminescent dosimeters (TLDs). Airborne radioactivity is collected continuously by passing air through a fiber filter in series with a char:oal absorption media. He filter collects particulate radioa:tivity, and the charcoal collects radiciodine. Waterborne radioa:tivity levels are O monitored by taking drinking water, surfa: vater, and naine samples. Ingested radioactivity is collected by obtaining samples of vegetation, milk, and fish. examining the distribution of radionuclides in the environment and lower trophic levels, comparisons are made with the preoperational data to determine if there are any biological or physical cGmpartments O in nature that are a::umulating radioactivity. Similarly, external radioa:tivity measurements taken after plant operation are compared with the average and range of data obtained in the preoperational program. A se:ond comparison of external radiation measurements is made by selecting TLD stations considered to be out of the radiological influence of the plant and using them as a measure of natural backgmund exposure. Dese referen:e stations are compared with the remaining stations to make estimates of any increases in external exposure levels that can be attributed to operation of DCPP. O To ensure that the program continues to include environmental sample locations most likely to detect plant-related radica:tivity, a land-use census is conducted annually. Changes in milk sampling locations may be required following the census based on relative potential doses or dose commitments and the availability of samples. O Continued environmental monitoring and surveillance under 'his program ensures early detection of any increase in exposures over the proposed 40-year operating license terms. 5.2.5 Nonradiological Sursei!!ance Program O 5.2.5.1 Environmental Protection Plan The Environmental Prote: tion Plan (EPP) was developed to provide for the prote: tion of the environment during constru: tion and operation of DCPP. The EPP is Appendix B to the Facility Operating Li:ense and has three prin:ipal obje:tives: (1) to verify that DCPP is operated in an environmentally ateeptable O manner, as established in the FES and other assessments, (2) to coordinate NRC requirements and maintain consisten:y with other federal, state and local requirements for environmental prote:! ion, and (3) to keep the NRC informed of the environmental effects of fa:ility constru: tion and operation and of q a:tions taken to control those effects. Environmental protection activities required by the EPP are l reported to the NRC in the Annual Environmental Operating Report. Any environmental con: erns O identified in the FES concerning water quality issues are deferred to the Regional Water Quality Control Board (RWQCB), as regulated under the National Pollutant Discharge Elimination System (NPDES) permit. The environmental issues in the EPP are categorized as aquati issues and terrestrialissues. The aquati: issues have been deferred to the RWQCB for resolution. Presently, the RWQCB protects the water O quality in the vicinity of DCPP through the provisions of the NPDES permit. Terrestrialissues include erosion control in the vicinity of the transmission line rights-of-way, the controlled use of herbicides on transmission rights-of-way, and the preservation of areas in the vicinity of DCPP of archeological significan:e and the provision of access to these areas by the Chumash Indian Tribe. The EPP contains specifi: requirements with regard to these issues. O

5.2.5.2 NPDES Permit ' An NPDES permit, No. CA0003751, to discharge Diablo Canyon ef0uents into the Pacinc Ocean has i been issued through the RWQCB. This permit describes all linuid discharges from the plant to the Pacific j Ocean and Diablo Creek to include cooling water, steam ge,.erator blowdown, makeup water systems, ' l seawater reverse osmosis system blowdown, radioactive waste treatment system, intake screen wash, biology laboratory discharge, and storm water runoff. Specific efnuent limitations and monitoring l requirements are established for various parameters depending on the probable constituents. These l limitations and requirements are based on Titles !!! and IV of the Federal Clean Water Act in accordance I with 40 CFR 122125 and 423, the California Water Code, and California Water Quality Control Plans. 3 Biological investigations, whi:h began in 1966 in the vicinity of Diablo Canyon, are used to support t compliance with NEPA and the Cuan Water Act. These studies are also used to ensure protection and propagation of the balan:ed, indigenous communities of shellfish, fish, and wildlife in the Pacific Ocean in and round the Diablo Canyon vicinity. NPDES permits are issued to Diablo Canyon every 5 years. 3 These permits contain requirements. as appropriate, for contiaued monitoring to ensure protection of the ' environment. The extensive studies to date have not identined any additional con: erns with relation to i the cooling water discharge to the Paci6: 0:ean. Required monitoring studies have been reduced in scope as a: cumulated information supports the absence of any significant effects. , D 5.3 ENVIRONMENTAL IMPACT DURING NORMAL OPERATION 5.3.1 Occupational Radiation Exposure  ; Diablo Canyon's o::upational exposure trend and comparison with the INPO 3-year industry average goal for PWRs are shown in Table 5-1. Diablo Canyon's average annual occupational exposures have consistently been below the INPO goal of 288 person-rem. As shown, aggressive implementation of the Al hA Program has resulted in a distinct reduction in exposures for the most recent 3-year perin i compared with the previous two averaging periods. ' Table 5-1 also shows the projected o::upational exposure averages per unit through the year 2000. The D proje: tion is based on resistance temperature detector (RTD) t,ypass elimination in 1994, and continued I operation with an 18-month fuel cycle. Assuming 3.5 person-rem per month for non-outage periods, and , savings of 50 person-rem per outage following RTD bypass elimination, the levelized 3-year average dose is projected"to de:rease to 150 person-rem per year per unit by 1997. Subsequent annual exposure averages can reasonably be expe:ted to remain approximately at this level, and within the INPO 1995 g 3-year industry average goal. These projected exposures are significantly less than the 450 man-rem per , year per unit values estimated by the Staffin the FES Addendum for Diablo Canyon. Given Diablo Canyon's current trend of decreasing refueling outage exposures and continued emphasis on effective refueling and outage management, it is expected that the base occupational exposures established above will serve as a realisti: estimate through the proposed 40-year period of operation.

With regard to the plant's liquid eftluent, a review of the actual liquid effluent since 1986 indicates that the maximum individual dose averages no more than 0.013 mrem per year. This represents only 0.43 percent of the Appendix I objective doses. From this operating experience, the plant has clearly

O demonstrated its capability to process waste to a degree that ensures continued compliance with
10 CFR 50, Appendix 1, design objectives.

i Gaseous eftluents from Diablo Canyon have also resulted in doses far below Appendix I objectives. Based on recorded noble gas eftluents over the past 5 years, the calculated maximum w) ole body dose i iO was, on average, only 0.07 mrem per year, or approximately 0.7 percent of the Apper. dix I dose objective of 10 mrem per year. Since this average maximum whole body dose occurred at the site bc.mdary, the plar.t's contribution to the total 50-mile population dose is insignificant in comparison to , th.9 from background radiation. j For iodines and particulates, dose calculations based on the actual releases over the past 5 years indicate

O that the average maximum annual organ dose is only 0.016 mrem per year. This represents just 0.11 percent of the Appentlix 1 dose criterion of 15 mrem per year to any organ. As with the noble gases, i

the r!cses from iodine and particulates also represent an insignificant frxtion of the total person-rem exposure the same 50-mile population receives each year from background radiation. !O Based on the design and performance history of the Waste Processing System, it is expected that offsite radiation exposures will remain within the plant's ALARA criteria through the proposed 40-year operating ' license terms. The projected exposures are also well within the offsite exposures estimated by the Staff , in the Diablo Canyon FES. It is important to note that the ALARA criteria are formally incorporated into the plant's operating Technical Specifications. Furthermore, the plant's contribution to the local l population dose within a 50-mile radius is expected to remain insignificant in comparison to that from

The ensironmental effects of extended fuel burnup and higher initial enrichment are addressed by the ) NRC in a Notice of Environmental Assessment and Finding of No Significant Impact published in tl. Federal Register on February 29,1988 (53 FR 6040). This notice stated that the NRC's environmental , assessment of extended fuel burnup and higher enrichment fuel is complete, and that the environmental 1 impacts summarized in Tables S 3 of 10 CFR 51.51 and S-4 of 10 CFR 51.52 bound the corresponding impacts for burnup levels up to 60 gigawatt-days / metric ton uranium (GWD/MTU) and enrichments up ) to 5 weight percent U-235. The environmental impacts of transportation resulting from the use of extended fuel burnup and higher enrichment fuel were further addressed in the Federal Register on August 11,1988 (53 FR 30355 - NRC Assessment of Environmental Effects of Transportation Resulting From Extended Fuel Enrichment and Irradiation). This notice reiterated the conclusion stated in 53 FR 6040 and further concluded that there ) are no significant adverse radiological or nonradiological impacts associated with the use of extended burnup and/or increased enrichment, and that burnup levels to 60 GWD/MTU and enrichments to 5 weight percent U-235 will not significantly affect the quality of the human environment. Moreover, pursuant to 10 CFR 51.31,

  • Determinations Based on Environmental Assessment,' the Commission determined that an environmental impact statement need not be prepared for this action.

)' Each Diablo Canyon reactor comains 193 fuel assemblies. The assemblies consist of fuel rods in a 17x17 . array. About 39 to 46 percent of the fuel assemblies are replaced every refueling. Since issuance of the operating licenses, PG&E has adopted several fuel design changes and improved fuel management schemes. These changes have significantly improved uranium utilization. ) To date, both Diablo Canyon units have been operating with nominal 18-month refueling cycles. It is anticipated that the units will continue to operate on the 18 month refueling frequency through the end , of the proposed 40-year operating license terms. in the Diablo Canyon FES, it was assumed for purposes of estimating the amount of uranium required ) that the plant would operate for 40 years with an 80 percent capacity factor. It was further assumed that the units would be refueled on approximately an annual basis. Since the Diablo Canyon units are refueled approximately every 18 months and improvements in uranium utilization have been made, the total amount of uranium required for the proposed 40-year operating license terms is expected to be less than the amount projected in the FES. ) 5.3.4 Spent Fuel Storage The Diablo Canyon spent fuel pools currently have onsite storage capacity for plant operation through about 2007 while maintaining the capability for a full-core off-load. After 2007, storage space would no . ) longer be available for a full-core off-load. The existing spent fuel storage racks will be filled by 2010. PG&E has a contract with the U.S. Department of Energy for the removal and disposal of Diablo Canyon ' spent fuel. The U. S. Department of Energy currently plans to begin accepting spent fuel for permanent disposal no later than 2010, and is considering providing interim storage in a monitored retrievable storage facility earlier than 2010. ) I 540SSIE5K 25 ) l

O 5.3.5 Solid Waste 5.3.5.1 Low Level Radioactive Waste O The volume of solid low level radioactive waste generated at DCPP has historically been among the i Iowest in the nuclear power industry. Table 5-3 compares the annual volume of solid waste generated at Diablo Canyon with the PWR industry median. These valaes show that Diablo Canyon has generated i significantly less solid waste compared with most PWRs and has followed the industry trend of reduced volume in re:ent years. During future years of plant operation, reducing solid waste generation will O c ntinue to be emphasized. The maximum solid waste volume for the proposed license terms should be about 75 cubic meters per year average for each unit, which is consistent with the recent rate of solid waste generation.

The average level of irradiation of the DCPP discharged fuel assemblies is less than 45,000 megawatt- l days per metri: ton uranium (MWD /MTU). The decay period after fuel is discharged prior to l {o transportation will be greater than 270 deys. The screening criteria of 10 CFR St.52(a)(3) are an average  ! level of irradiation not to exceed 33.000 MWD /MTU and no shipments until at least 90 days after discharge from the reactor. 4 540SS/S5K 26

O

@ l Although the average burnup level of the DCPP fuel assemblies exceeds the screening criterion in 10 CFR 51.52 (a)(2), the environmental effects for fuel burnups to 60,000 MWD /MTU have been evaluated and shown to be acceptable by the NRC. As discussed in Section 5.3.3., the NRC has 8 concluded that there are no significant radiological or nonradiological impacts associated with the use of extended burnup fuel and that fuel burnups to 60,000 MWD /MTU will not significantly affect the quality of the human environment. Furthermore, improved fuel cycle designs should result in less total spent fuel over the proposed 40-year operating license terms than was projected in the FES. O 5.3.5.3 Waste Shipping Radioactive waste shipped from the DCPP site is packaged in solid form in accordance with the requirements of 10 CFR 61 and the screening criterion of 10 CFR 51.52(a)(4). Unitradiated and irradiated fuel from the DCPP site will be shipped in accordance with the requirements of 10 CFR O Sl.52(a)(5). The screening criteria require truct shipment for unirradiated fuel and truck, rail, or barge shipment for irradiated fuel. Depanment of Transportation and NRC regulations provide protection of the public and transport workers from excessive radiation exposure. Protection is achieved by standards and requirements applicable to packaging, limitations on the contents and radiation levels of packages, and procedures to limit the g exposure of persons under normal and postulated accident conditions. Primary reliance for safety in transport of radioactive material is placed on the packaging. The packaging must meet regulatory standards (10 CFR 71 and 49 CFR 173) established according to the type and form of material for containment, shielding, nuclear criticality safety, and heat dissipation. The standards require that the packaging prevent the loss or dispersal of the radioactive contents, retain shielding O efficiency, assure nuclear criticality safety, and provide adequate heat dissipation under normal conditions of transport and under specified accident damage test conditions. 'Ite contents of packages not designed to withstand accidents are limited, thereby limiting the risk from releases that could occur in an accident, and to ensure standards for radiation levels, .emperature, pressure, and containment are met. O 5.3.5.4 Solid Waste Conclusions The amount of nuclear fuel and volume of solid waste resulting from the proposed 40-year operating license terms will continue to be within the limits assumed for the original licensing basis. Because of O improved fuel cycle designs, the total amount of spent fuel produced over the proposed 40-year operating license terms is expected to be less than that originally projected in the FES for DCPP. Based on the above, PG&E concludes that the radiological and environmental impacts from the storage and transportation of irradiated fuel and solid radioactive waste are consistent with the impacts set forth in Table S-4 of 10 CFR 51.52, and the environmental costs will not be significantly affected during the 3 proposed 40-year operating license terms. 5.3.6 Thermal and Ecological Effects of the Cooling Water System The DCPP cooling water system is a once-through system discharging directly into Diablo Cove of the $ Pacific Ocean. The potential ecological effects of the cooling water system are: (1) those resulting from elevated water temperatures in portions of Diablo Cove, (2) entrainment of organisms in the cooling water 540S5/85K 27 D

9 system, (3) impingement of organisms on the intake traveling screens, and (4) scouring effects of the dischrge in the intenidal zone at the point of discharge. 1 These effe:ts have been extensively studied and the study results were considered in issuan:e of the g NPDES Permit and renewals (see Section 5.2.5). The NPDES Permit is conditional upon the discharge complying with provisions of Division 7 of the California Water Code and of the Clean Water Act (as amended or as supplemented by implementing guidelines and regulations) and with any more stringent effluent limitations necessay to implement water quality control plans, to protect beneficial uses, and to prevent nuisan:e. Two of the findings of the California Regional Water Quality Control Bond, Central Coast Region (Bord) as noted in the current NPDES Permit (Bord Waste Dischuge 8 Requirements Order No. 90-09) are:

  • Thermal effe:ts on the receiving water, actual temperature i reases, and e:tual temperatures of the discharge are monitored and results correlated and evaluated hs pan of ongoing studies. These studies are being performed as required in Monitoring and Reponing Program No. 90-09. This monitoring

" is developed and reviewed jointly by Board and Department of Fish and Game staff. The results of the studies are useJ to evaluate thermal limits.

  • Section 316(b) of the Clean Water Act requires that the location, design, construction and capacity of cooling water intake structures refle:t the Best Technology Available (BTA) for minimizing adverse environmental impa:t.

J An April 25, 1988. study of the cooling water intake structure was submitted to the Bord whi:h concluded the facilities at Diablo Canyon Power Plant reDe:t BTA. Funher, the Monitoring and Reporte.g Program requires PG&E to continue ecological studies as approved by the Executive Of5:er in order to evaluate changes in distribution and abundance of marine plants and animals within the 3 vicinity of the discharge. These operational studies have indicated that the effects of the discharge are consistent with the preoperational studies and mudelling predictions; i.e., that the dischrge would not signWantly affe:t the marine e: ology in the vi:inity of DCPP. The Board and Department of Fish and Same have found the observed th:.nges (mainly in relative abundan:e of species) to be a::eptable. Additional discharge and thermal effects are not anti:ipated based on operational data colle:ted sin:e J 1984. Accordingly, the basis for the Board's order is expected to remain valid when the NPDES Permit is renewed in 1995 and thereafter. 5.3.7 Protection of Historic Properties g' In 1966, Fran:is Riddell conducted a survey for PG&E of approximately 250 a:res to be used as the site for DCPP. In 1968, Greenwood and Associates undenock subsurface investigations for PG&E at six sites within the construction areas for the DCPP facilities and a proposed access road from the plant site to Avila Bea:h. Based on these excavations, Greenwood in '1972 suggested that an area of the DCPP site, SLO-2, was a major village whi:h figured prominently in the social, economic, and political life of the J indigenous occupants of the area. The 1968 excavations at the site resulted in the identincation of one of the oldest culturally strati 6ed sites identiDed to date in San Luis Obispo County. These 1968 studies by Greenwood are discussed in the Diablo Canyon FES where it mentions three archaeologi:al sites in the plant rea were investigated by archaeologists. g in 1978. Greenwood and Associates reponed on a sursey of 90 acres of land thought to be the areal extent of site SLO-2. This repen centained information to be used for the nomination of SLO-2 to the 540SS!S5K ;g O

O National Register of Historic Pla:es. The SLO-2 site, whi:h was determined to be eligible for the National Register of Histori: Pla:es in December of 1982 by application from the Nuclear Regulatory Commission, in:ludes the locations of recorded sites SLO-2, SLO-3, and SLO-8. In a: ordan:e with 36 CFR S00, a determination of no-effect was made by PG&E in hiay 1984 in conjunction with the California Historic Preservation Of6cer. The NRC agreed with the no-effect determination in a transmittal to PG&E on June 25,1984, stating that operation and maintenance of the plant will not affect cultural resources (SLO 2) listed in or eligible for inclusion in the National Register of Histori: Pla:es. 9 Since November 1983, photographs have been taken at regular intervals from 23 stations within the site to monitor any physical changes to the site caused by natural or other processes. Further, a Cultural Resources hianagement Procedure Plan has been drawn up which provides speciS guidelines regarding future management of SLO-2 by PG&E The Archaeological Resources hianagement Plan (ARhfP) and these procedures have been approved by the State Historic Preservation Ofncer as pan of PG&E's compliance with the National Historic Preservation Act (36 CFR 800). In the spring of 1986, unexamined portions (an area of approximately 495 a:res) of the DCPP property were investigated for cultural resources. A total of six prehistoric sites were recorded and/or relocated during this study. This included three previously unrecorded sites, SLO-1161, SLO-1162, and SLO-1163 g and one previously re:orded site, SLO-61. In addition, site forms were completed for Riddell sites 3 (SLO-1159) and 5 (SLO-1160) whi:h had not been recorded with the California Archaeological Survey. PG&E utinues to man:we and prote:t the histt n: propenies at DCPP in consultation with the California State Histori: Preservanon OfG:e and the local Native American communities. As a result of this aggressive management, PG&E con:ludes, as did the NRC in 1984, that operation of DCPP throughout O the 40 year operatir.; li:ense terms will not adversely affe:t any known historic sites. 5.4 EXPOSURE FRO 31 RELEASES DURING POSTULATED ACCIDENTS g The offsite exposure from releases during postulated a::idents has been previously evaluated in the DCPP FS AR Update. The results are a::eptable when compared with the criteria denned in 10 CFR 100. This type of evalunion is a function of four parameters: (1) the types of a:cidents postulated, (2) the radios:tivity release :alculated for ea:h a::ident, (3) the assumed meteorologi:al conditions, ad (4) population distribution versus distan:e from the plant. On the basis of the safety assessment in Section 4.0, it can be concluded that neither the types of accidents nor the calculated radion:tivity releases O will change through the proposed 40-year operating license terms. Furthermore, the site meteorology, as denned in the FSAR Update, is essentially constant. Thus, population is the only time-dependent parameter. It is important to note that there is no expected change in land usage during the license terms that would affect offsite dose cal:ulations. g The population si:e and distribution in the vicinity of the plant have been reviewed several times sin:e J the constru: tion permit was issued: in the FES in 1973 (through the year 2000), in the original FSAR l in 1974, in the 1985 FSAR Update using 1980 census data, again in late 1991, and in a review of the l California Depanment of Finance projections through 2025 performed for the purpose of the proposed li:ense terms. The Department of Finance projections indicated that a compound average growth rate of 215 percent is expe:ted for the 50 mile radius area around Diablo Canyon through the year 2025. 9 Tab!e 5-4 summarizes the projected population size and distributions. 540SS 55K ;9 0

  • Reflects Low Population Zone J The plant exclusion area depicted in Figure 5-1 will remain uninhabited through the proposed license terms. The activities within the exclusion area only pertain to normal plant operation. No part of the  !

ex:hision vea will be sold, and no structure will be located within it except those owned by PG&E or , a related company and used in conjunction with normal utility functions. No residences will be permitted on the site. J The Low Pcpulation Zone (LPZ) for DCPP is the area included within a 6-mile radius of the site, as shown in Figun 5-2. This land area was sele:ted because it meets the requirements of 10 CFR 100 with respe:t to proximity to the nearest population center. The major population centers (with populations of 25,000 or more) currently within 50 miles of Diablo 3 Canyon are Lompo: (1990 population 37,649), about 45 miles to the south-south-east; Santa Maria (1990 population 61,284),29 miles to the south-east; and San Luis Obispo (1990 population 41,958),10 miles to the east-north-east. Accordingly,10 miles is currently the Population Center Distance (PCD). However, population projections indicate that the community of Baywood-Los Osos (8 miles to the north) l v ill reach a population of 25,000 in approximately the year 2020. The 2020 projected population for 3 Baywood-Los Osos is 26,844. Accordingly, the PCD would become 8 miles in approximately 2020. i Federal Regulation 10 CFR 100.11(a)(3) provides that the PCD be at least 1-1/3 times the distance from the reactor to the outer boundary of the LPZ. The community of Baywood-Los Osos, at 8 miles north, j will satisfy this rule as the projected PCD in the year 2020, thus requiring no change in the definition of the current LPZ now or during the proposed 40-year operating license terms. The changes projected for the population distribution through 2025 will not impact the boundaries used for existing accident analyses. The current exclusion area boundary, LPZ, and nearest population center , distance will continue to meet the requirements of 10 CFR 100.11(a)(3) for the proposed 40-year license I terms. Accordingly, the proposed 40-year operating license terms will not affect previous conclusions greached in the Staffs SER and FES on the potential environmental effects of offsite releases from ) postulated a::idents. 540SS/S5K 30 )

I S 5.S ENVIRONMENTAL RELATED PLAhT MODIFICATIONS Several environmental related plant modifications have been made since issuance of the FES and Addendum. These changes funher reduce the environmental impacts associated with DCPP operation and in:lude the following: O e Wastewater Holding and Treatment (%HA T) System - ne WH AT System includes storage tanks and associated equipment for improved storage and treatment of wastewater. He tanks are placed in a concrete retention basin for secondary containment.

  • Wastewater Routing - Pumps and piping were added to route wastewater from the turbine building sump to the WHAT System, allowing for treatment prior to discharge.
  • Ha:ardous Waste Storage - A building was provided for the storage of containerized hazardous waste prior to offsite shipment. Other areas in the plant are designated for hazardous waste storage. These storage areas are provided with fire protection equipment and secondary conta'mment features to O prevent the release of hazardous waste to the environment.
  • OilSpill Prevention - A spill prevention pond was constructed at the 230 kV switch yard to prevent oil from transformer leaks from entering Diablo Creek.
  • Seawater Reverse Osmosis System - A Seawater Reverse Osmosis System was provided as an C additional source of makeup water for the plant, effectively replacing the seawater evaporator described in the FES.
  • Discharge Structure Modifcations - To reduce the, peak temperature of cooling water being discharged from the plant, modifi:ations were made to the discharge structure. These modifications O allow for better mixing of water between the two units and included cutting openings in the c'entral wall of the discharge structure and modi 6:ation to the weirs.

e intate/ Discharge Temperature Monitoring - An improved temperature monitoring system was installed to measure the cooling water teniperature at the intake and discharge structures. This system g initiates an alarm in the plant control room when a set temperature difference is exceeded.

  • Expanded Sewage Treatment - To allow for increases in plant staffmg, an expanded sewage treatment system was constru:ted that provides for secondary treatment of effluent. He system discharges to the cooling water system and is monitored as required by the NPDES permit. An expanded lea:h field was provided as a ba:kup for the secondary treatment system.

O

  • Chlorination System Modifcations - Modifications to the Chlorine System include (1) the use ofliquid hypochlorite to control microbiofouling instead of gaseous chlorine, (2) implementation of continuous chlorination of the auxiliary saltwater system to control macrobiofouling (invertebrate marine life),

and (3) possible use of intermittent injection of a chlorine / bromine mixture to prevent macrofouling in the Circulating Water System.

I Most of these plant design modifications and changes have had a direct positive impact on the 'l envir nment; f r example, chemical discharges have decreased and spill prevention has improved.  :

O Changes have been conducted in accordance with approved procedures, current license conditions,  ! Technical Specification requirements, and environmental permits. Additional plant modifications and i changes may be 5plemented during the proposed 40-year operating license terms.~ For example, the  ! Radiation Monitoring System is presently being upgraded to improve performance, reliability, and' , capability. Based on past experience, future changes are r.ot expected to have a significant negative j impact on the environment and should provide improved means to monitor potential environmental  ! effects. . 5.6 DECOMMISSIONING In accordance with 10 CFR 50.33(k), PG&E submitted a decommissioning report to the NRC that provided reasonable assurance that sufficient funds will be available to decommission the plant. Additionally, PG&E prepared a preliminary decommissionirq cost study for DCPP. This study was last , updated in May 1991 to reflect recent changes in costs and schedules. O. The decommissioning study provides cost, schedule, waste generation / disposition, and radiation exposure , estimates associated with the decommissioning of the DCPP nuclear units following cessation of  ; operations. The alternatives evaluated were DECON (prompt removal / dismantling) and SAFSTOR l (mothball with delayed dismantling). The plant retirement dates were taken as 30 years following  ; commercial operation. This timeframe was used as input in scheduling analysis. O The decommissioning study did not determine the incremental impact on decommissioning due to the .! proposed 40-year license terms. However, PG&E anticipates that the proposed 40-year operating license

l. terms will have a negligible incremental environmental and cost impact on decommissioning the DCPP .;

units. A reactor's activation product inventory rapidly builds up and reaches an equilibrium level, so that  : ( , after 10 years of operation the inventory is approximately 90 percent of the total expected after 40 years l h of operation. As a result, most of the fa: tors affecting costs for decontamination and decommissioning, !- 1 i  ; 540?S/ESK 34 ) C. t 1 p ear- y ,-- W - - - ^ + -

J as well as occupational exposure, arise early in a reactor's operating life. Thus, the proposed 40-year operating license terms will not add significantly to the cost and effort to decommission the plant. Moreover, it was concluded in NUREG-0586, " Final Generic Environmental Impact Statement on

,    Decommissioning of Nuclear Facilities," that decommissioning is not expered to significantly impact the environment. The NUREG also categorically excludes power reactors from tne mandatory Environmental Impact Statement requirement for decommissioning. The other key conclusions of this report were:
  • Decommissioning at the present time can be performed safely and at reasonable cost.

O e Decommissioning of nuclear facilities is not an imminent health or safety problem. e Decommissioning of a nuclear fa:ility generally has a positive environmental irmact. Therefore, PG&E concludes that any changes in the environmental impact associated with decommissioning after expiration of the proposed 40-year license terms will be negligible.

 -,J 6,0    NO SIGNIFICANT HAZARDS EVALUATION PG&E has evaluated the no significant hazard considerations involved with the pwposed amendment, D    focusing on the three standards set forth in 10 CFR 50.9:(c) as quoted below:

The Commission may make a final determination, pursuant to the procedures in 6 50.91, that a proposed amendment to an operating license for a facility licensed under i 50.21(b) or i 50.22 or for a testing facility involves no significant hazards q consideration, if operation of the facility in accordance with the proposed amendment

 ~

would not:

1. Involve a signifi: ant increase in the probability or consequences of an accident previously evaluated; or O 2. Create the possibility of a new or different kind of accident from any a:cident previously evaluated; or
3. Involve a signifi: ant redu: tion in a margin of safety.

The following evaluation is provided for the no significant hazards consideration standards. 3

1. Does the change involve a significant increase in the probability or consequences of an accident previously evaluated?

The proposed 40-year operating license terms do not affect the probability or consequences of an J accident previously evaluated since the requested extensions entail no physical change in the plant ecuipment or operating procedures and the FS AR Update safety analyses are based on 40-year plant operation. Surveillance and maintenance pra:tices, as well as other programs such as environmental qualification of equipment, ensure timely identification and correction of any degradation of safety-related plant equipment. The long term integrity of the reactor vessels has been recently reevaluated

 ,         using currently acceptable NRC calculational methods and best available DCPP-specific data. The evaluation results demonstrate, as before, that both reactor vessels are safe for normal operations l

540SS/85K 35 3 I

i n excess of 40 years. Also, the offsite radiation exposures resulting from postulated accidents have O been reanalyzed using population projections for the propos ed 40-year operating license terms. The calculated exposures are not significantly different from those documented in the FSAR Update and are well within 10 CFR 100 guideline values. I herefore, the proposed changes do not involve a signifi: ant increase in the probability or , O consequen:es of an a:cident previously evaluated.

2. Does the change create the possibility of a new or different kind of accident from any accident previously evaluated?

The possibility of a new or different kind of a:cident is not created by the proposed 40-year  ; O operating license terms since at least 40-years operation was assumed in the design and construction of DCPP Units 1 and 2. The plant Maintenance Program is designed to both maintain and determine the need to replace safety-related components. Thus, any degradation that might possibly create a new or different kind of postulated accident would be detected and corrected before the occurrence of such an event. O Therefore, the proposed changes do not create the possibility of a new or different kind of accident  ; from any a cident previously evaluated.

3. Does the change involve a signifi: ant reduction in a margin of safety?  ;

O The proposed 40-year operating license terms do not involve a signifi: ant reduction in a margin of i safety since degradation of safety-related equipment will be identified and corrected by ongoing  ! surveillan:e and maintenance era:tices. Existing programs, routine maintenance, and compliance with Te:hnical Spe:ificaticns assure that an adequate margin of safety is maintained. These activities will remain in effe:t for the duration of the operating licenses. 7 O Therefore, the proposed changes do not involve a significant redu: tion in a margin of safety. i In conclusion, based on the above safety and environmental evaluations, PG&E submits that the activities associated with this license amendment request satisfy the no significant hazards consideration standards of 10 CFR 50.92(c), and, accordingly, a no significant hazards finding is justified. Such a finding is O consistent with NRC Staff approval of numerous appli:ations of this tjpe. PG&E requests that, if ' necessary in a::ordance with the provisions of 10 CFR 50.91(a)(4), the NRC make a final determination that no significant hazards considerations are involved and issue a license amendment in a:cordante with  ! this request.

This Program Directive addresses NPGBU's program for the planning, , scheduling, and performance of preventive and corrective maintenance on () plant equipment, and the performance of repairs and replacements of

                                                                                                    +

components covered by Section XI of the ASME Code. It applies to safety related systems, structures, and components (SSC) and other i specified equipment that affect safe and reliable plant operation. The ' overall objective of the maintenance program is to prevent the i' degradation or failure of plant equipment. The hierarchy of procedures .() associated with this PD is illustrated in Figure 1. ' Effective maintenance is essential to plant safety and to the reliable and efficient operation of DCPP. Effective maintenance can reduce the ' frequency of events and challenges to safety systems as well as enhance f the operability, availability, and reliability of such systems.

<3 Maintenance also helps to minimize failures of non-safety related

equipment that could result in off-normal plant conditions or affect  ! l ' safety system performance. Finally, effective maintenance will help ' ensure that assumptions and margins in the original design basis and other engineering evaluations (e.g., probability risk assessment (PRA), ) individual plant evaluations (IPE), etc.) are maintained. j 'O Good maintenance is-also an important determinant of plant performance. The time required to perform maintenance activities during normal operations and outages, and the ability to implement maintenance prior to loss or significant degradation of equipment function, are critical , to overall plant availability. These considerations provide a ' C) c mpelling basis for implementing effective maintenance management with clear and specific delineation of policy considerations and responsibilities.

O N I. INTRODUCTION The Systematic Assessment of Licensee Performance (SALP) is an integrated f C) HRC staff effort to collect available observations and data on a periodic basis and to evaluate licensee performance based on this information. The ' program is supplemental to normal regulatory processes used to ensure com-pliance with NRC rules and regulations. It is intended to be sufficiently i diagnostic to provide a rational basis for allocating NRC resources and to  : provide meaningful feedback to licensee management regarding the NRC's l IC) assessment of their facility's performance in each functional area. 2 An NRC SALP Board, composed of the members listed below, met in the Region V office on January 21, 1993, to review abservations and data on the licensee's performance in accordance with NRC Manual Chapter 0516,

                  " Systematic Assessment of Licensee Performance."

SUMMARY

OF RESULTS A. Overview - O The licensee's overall performance level during this assessment period was good or superior in all areas. Examples of superior performance were demonstrated by relatively event-free operation, low occupational radiation exposure, awareness and training of personnel to minimize safety risks during outages, prompt and aggressive response to indications of O cracking in feedwater piping nozzles, and aggressive and well focused insight into performance weaknesses by the Onsite Safety Review Group. The strength; observed 'n the Operations, Radiological Controls, Engineering / Technical Support, Emergency Preparedness, and Safety Assess-ment / Quality Verification functional areas resulted in these areas being O rated as Category 1. The board noted in the functional area of tiaintenance/ Surveillance that early in the SALP period there were a few problems involving prompt problem identification and resolution, and engineering involvement in maintenance issues. The board concluded, however, that the overall performance was superior based on strong corrective actions and very high quality performance throughout the o remainder of the period. While strengths were noted in the security area, security management did not appear to have conducted an adequately broad examination of their activities to assure a high standard of performance throughout the organization. The board discussed HRC-identified problems at length, e particularly in compzrison with the high level of performance seen in most of the security organization. While corrective actions were taken for specific problems 'hatified by the NRC, it appeared that the requirements of the security organization had not been implemented with a consistent level of assurance of quality. Although management appeared to have , corrected weaknesses noted during the previous SALP period, weak manage-D ment involvement in maintaining high quality in all security program areas detracted from otherwise su;'rior performance in this area. B. Results of Board Assessment Overall, the SALP Board found the performance of NRC licensed activities e to be very effective and directed toward safe operation of Diablo Canyon. i The SALP Board has made specific recommendations in most functional areas  ; for licensee management consideration. The results of the Board's assess-ment of the licensee's performance in each functional area, along with the  ; results from the previous period, are as follows: l

PERFORMANCE ANALYSIS The following is the Board's assessment of the licensee's performance in each of the functional areas, along with the Board's conclusion for each 'O area and its recommendations with respect to licensee actions and management emphasis. __ A. flant Operations j i

1. Analysis j During the assessment period, the resident inspectors conducted frequent inspections involving observation of operations activities.

Some engineering section and project inspector inspections also evaluated operations activities. Review of operations activities ! accounted for about 34 percent of the total inspection effort. The last SALP assessment rated the licensee's performance in this area Category 1. Strengths were noted in relatively event-free operation, and in superior operator response to plant transients. Operations exhibited significant strength in conservative operational , decisions. The previous SALP Board also noted weaknesses in occa-  !

O sional lack of timeliness in identifying and resolving problems and  !

in issuing operability determir ations. During this SALP assessment period, the licensee continued to show t superior performance in this area. Strengths were observed in the - general high quality of the Operations staff's performance, and in

O relatively event-free and uncomplicated operations. Management involvement has been frequent and probing, assuring timeliness in  ;

identifying and resolving problems and in making operability deter-minations. Operations management has set high performance standards i which have usually been met or exceeded. 10 Recovery from each event, regardless of cause, and the subsequent root cause investigation indicated significant strengths. cThis was ' due in part to a high level of skill and sense of ownership among the Operations staff, and to intensive management involvement at all levels of the organization.

o During operations at power and during outages, the Operations staff showed strong awareness of overall plant safety system availability and the significance of evolutions relative' to the risk to the plant.

i This appeared to have been a direct result of aggressive management j connitment to plant safety and risk reductions. The licensee developed and implemented a comprehensive and effective outage plan .o that appropriately considered risk associated with plant shutdown evolutions. Operations staffing levels appeared to be appropriate, and operations staff qualifications were strong.

                                                                              ,. }

J Other examples of significant strengths were as follows: Active Operations involvement with maintenance crews near sensitive equipment helped to avert events. Documentation of operability determinations was strong, timely and consistent. Also, a very low threshold was established for the level of equipment degradation which required an operability evaluation. D + Operations simulator training was challenging and effective, and critiques appeared to be appropriately critical and probing. Toward the end of the SALP period, Operations personnel were progressively more alert to anomalous plant conditions. For D example, an operator's observation and followup of a failed fastener resulted in identification and repair of a degraded neutral connector to a main transformer, potentially averting a plant trip. During this SALP period, two severity Level IV violations occurred in this area. One was a repeat violation, for operation in Modes 2 and D 3 with one of two reactor cavity sump wide range level channels inoperable. The other violation involved inadequate instructions to operators for avoiding excessive piping vibration on loss of speed control to the positive displacement charging pump. Neither had an impact on safe plant operation, and each of these instances was promptly corrected. During the first part of the SALP period, a few Licensee Event Reports (LERs) were issued as a result of personnel errors. Although this was not an unusually high rate, the concern was that it indi-cated an increasing trend. The personnel error rate was reduced D later in the assessment period as a result of strong management invol vement. Four isolated instances of minor weakness were observed, either in following procedures or in coordination with other groups. The most significant involved an inadvertent chemical spill, which generated 8 noxious fumes and prompted declaration of an Unusual Event. Another instance occurred as a result of unclear procedures, which allowed a condenser vacuum pump to be started before its seal water isolation valve was opened. This uitimately resulted in a reactor trip. In each of these cases, root cause evaluation and corrective actions were immediate and appeared appropriate. 8 In summary, the performance of Operations has been strong, and has continued to improve. Weaknesses have been minor, isolated and infrequent, and have been corrected promptly and appropriately.

3. Recomendations None b B. Radiolooical Controls
1. Analysis Radiological controls inspections during this SALP period found that  !

y the licensee continued to be aggressive in assuring quality. Radio- I active effluents continued to decrease, and occupational dose was  ;

           . reduced in 1992 despite a demanding outage schedule. A continued        l strength was the licensee's innovative approaches to improving         :

measures for personnel radiation protection. Minor weaknesses ) identified, related to radiological porting and labeling..were solved l y rapidly and thoroughly. Regional inspectors examining this  : functional area contributed approximately 5 percent of the total inspection effort during this assessment period. [ The licensee's radiological controls performance during the previous  ! SALP period was rated Category 1. The previous SALP Board recom- l mended that management continue _to fully support site and corporate k initiatives for improving performance. The board also recommended  ; added emphasis toward correcting minor weaknesses in controlling personnel contaminations, reducing the backlog of non-Technical i Specification radiation monitoring equipment needing calibration, and  ; training dosimetry clerks and radwaste handlers. l ) During this assessment period, management continued to be proactive in assuring quality. The ALARA awareness program, established to j reward outstanding outage performance, continued to be an effective ' incentive toward meeting rigorous ALARA goals. The 1991 average i occupational dose per reactor was 273 person-rem, and for 1992 was l 214 person-rem. Liquid effluents continued to decrease. Gaseous )- effluents were also maintained at a small fraction of the Technical Specification limits. Management support was evident in the elaborate remote monitoring capabilities used to support steam generator shot peening and eddy i ) current testing during the IR5 outage. Use of this equipment  ! significantly reduced both the dose received and the radiological risk involved in conducting several complicated, high-dose tasks at once. In addition, corporate involvement and support was evident in , continuing efforts associated with a major upgrade of radiation and i effluent monitoring equipment. ) The licensee's approach to resolving technica' issues was conserva-  ! tive and timely, and demonstrated a clear unde. standing of the issues involved. -In September 1992, the licensee voluntarily made a presen-tation to members of the NRC Region V staff concerning the status of radiation monitoring system upgrades. Detailed alternate monitoring y methods had.been analyzed, for use during interim periods while sys-r tem upgrades were being performed, to ensure proper monitor ranges, efficiencies, and sensitivity to airborne radioactivity. Technical )

e improvements were observed in licensee programs for radwaste classi-fication, the process control program, and radiological environmental monitoring. Technically sound judgment was also in evidence in the

  1. licensee's radiological controls preparations for potential high-dose outage tasks, such as steam generator shot peening, steam generator eddy current inspection, and core barrel inspection.

Licensee management support of training was demonstrated by the extensive efforts made in mock-up training prior to the IR5 outage. The steam generator cock-up included a fully operational shot-peening 3 apparatus. One weakness was observed involving failure to thoroughly train eddy current testing personnel on the impact that shot peening would have on steem generator airborne radioactivity hazards. A Severity Level IV violation was cited for the resulting hazard. The licensee took prompt corrective action to resolve this weakness. 3 The licensee's other training practices continued to exhibit excellence. Training and qualification programs made a positive contribution to the understanding of radiological controls issues and adherence to procedures. Staff members were kept abreast of industry knowledge and development through extensive participation in offsite J, owners' group meetings, Electric Power Research Institute (EPRI) conferences, and other opportunities for offsite involvement. An improvement was noticed in the licensee's training of radwaste handlers. Training on the new 10 CFR 20 requirements also continued for appropriate personnel. 3 The licensee's site and corporate radiological controls and chemistry groups continued to be well staffed. Key positions were generally filled on a p,iority basis. Authorities and responsibilities, both in the chemistry and radiation protection organizations, were well defined, and resulted in clear communications both within the groups and with other site orgsnizations. 3 One voluntary Licensee Event Report (LER) was submitted relevant to radiological controls during this assessment period. The LER dealt with overexposures received by contract radiographers, due to personnel error by the radiographers while performing radiography on the licensee's site. Three Severity Level IV violations were , identifi;J in this functional area. Two resulted from inadequate J posting and labeling, and one involved the failure to implement procedures to control airborne radioactivity from steam generator work. tieither the violations nor the LER indicated a programmatic breakdown of the radiation protection program. The licensee's root cause analyses and correttive actions were prompt and were ,J effectively implemented.

g . C. Maintenance / Surveillance

1. Analysis 0:

During the assessment period, the resident inspectors conducted frequent inspections which included observation of maintenance and surveillance activities. Engineering inspections also evaluated ' i maintenance and surveillance programs. Review of maintenance and surveillance activities accounted for about 10 percent of the total l O Diablo Canyon inspection effort. { The last SALP assessment rated the licensee's performance in this I area Category 2. Strengths were noted in the initiation of a program  ! for trending safety equipment out-of-service time, and in the use of 4 probabilistic risk assessment to evaluate preventive maintenance O programs. Weaknesses were noted in a lack of management aggressive-  : ness in dealing with problem areas; occasional failure to follow  : procedures, resulting in safety significant events; and a tendency for personnel errors due to lack of self-verification. The licensee was encouraged to involve management in timely problem identification -, and root cause investigation, and to continue to support industry  : initiatives. O During this assessment period, the licensee generally displayed improved performance in this area. Virtually trouble-free plant > operation evidenced a high quality of maintenance work in that no plant events and almost no equipment failures occurred as a result i O of improper maintenance. Strengths were observed in the general. high quality of maintenance and surveillance work. Additionally, a , high level of management involvement in scheduling and pianning  ; maintenance and surveillance work maximized safety system avail-ability from a probabilistic risk standpoint, both at power and during outages. This resulted in a ' considerable benefit to plant O safety. Noteworthy strengths were as follows: ' Outaae Manaaement: The management of outages was marked by an overriding understanding and emphasis of the probabilistic risk O. of each job and evolution. Work crews and planners were trained i and aware of the safety significance of the jobs and systems on ' which they worked at every stage of the outage. Oualifications: The training and qualification program for Maintenance personnel was strong. Well maintained training  ; O facilities and a dedicated training staff were significant i factors in good performance, as was the sense of ownership shown  : by Maintenance personnel. ' Plant Safety: Maintenance personnel were trained and informed i regarding overall plant safety system availability and the  ; O. significance of their individually assigned work relative to its risk to the plant. , i O .

                                            -o -
  • prioritization of Work:~ Outstanding work items were well prioritized, with safety-significant issues given high priority.

The backlog of non-outage safety related work items was low. 'O . Root Cause Investications: The routine involvement and leadership shown by the Plant Maintenance staff in root cause investigations was a significant strength, as was the routine integration of the Maintenance, Operations, and Engineering staffs in maintenance and surveillance operations. O . Reduction of Personnel Errors: A relatively high number of personnel errors were observed at the beginning of the SALP period. Several of these errors resulted in conditions wh'ch prompted a Licensee Event Report or Non-conformance Report. This number was reduced by about half during the remainder of the period due to a high level of management involvement O throughout the organization. Response to Problems: Overall, the maintenance staff improved their response to problems by identifying, analyzing and cor-recting maintenance and surveillance problems promptly. This O represented an improvement over the last assessment period. Examples of this improvement were the identification and correc-tion of an incorrect reactor coolant system leakage surveil-lance; prompt, in-depth evaluation and compensatory action for problems with auxiliary feedwater pump steam admission valve FCV-95; and improvement of the clarity of some instrumentation O and control surveillances. Four Level IV violations were cited in this area, involving improper maintenance of containment fan cooler unit (CFCU) backdraft dampers, failure to perform a containment airlock surveillance, failure to identify inconsistencies in a pump vibration measurement procedure by O writing an action request, and improper rigging of a cask. In some cases, as illustrated by the inoperable containment fan cooler unit backdraft dampers, Engineering involvement should have been more timely. Improper maintenance of CFCU dampers was significant in that the dampers were not functional, and only after additional analysis did the licensee determine that the CFCUs had been operable despite O the improper maintenance. These concerns appear to have been iso-lated, although the CFCU issue was potentially significant'to safety. Other weaknesses were also observed. One example was the improper tightening of setscrews on some motor operated valve actuators, resulting in a common mode failure vulnerability. Additional, less O significant weaknesses were observed. Most were identified by the licensee immediately upon occurrence. Management involvement was effective, and identified problems were promptly and appropriately corrected. Most of these examples occurred early in the SALP period. Since that time, significant improvement has been noted.

1. Analysis i O

Two routine emergency preparedness (EP) inspections and two annual emergency exercise team inspections were conducted during this assessment period. Review of the EP program accounted for approxi- ' mately 6 percent of the Diablo Canyon inspection effort. A strength , identified during the current assessment period was in making timely O and appropriate classifications during most actual emergency events, exercises and drills. A weakness was r.oted regarding the making of protective action recommendations (PARS) to offsite agencies during the 1991 annual emergency exercise. Generally, licensee performance in the EP area appears to have improved over the assessment period.  ; 'O The licensee's EP performance in the last SALP cycle was rated Category 2. The SALP board at that time indicahi several recommen-dations: that management ensure the establishment and implementation of an effective corrective action plan for drill and exercise ' findings; that licensee management evaluate the adequacy of classroom  : training provided to emergency response personnel and ensure that  ! O personnel are given an adequate number of opportunities to practice their assigned tasks during periodic drills; that the additional dose assessment training provided to Control Room personnel continue; that r the need to adhere to radiation protection procedures under simulated emergency conditions also be stressed during classroom training and drills; that administrative procedures be enhanced to ensure that O drills and exercises consistently meet emergency plan requirements; and that simulation of sample collection during drills and exercises  ; be avoided to enhance realism and increase the training value. During the current assessment period, licensee management appeared actively involved in EP activities and demonstrated support by , o providing the necessary resources to the EP staff. Management took interest in correcting problems and responding to NRC findings which indicated a need for corrective action. During the assessment i period, the licensee worked closely with the state, local county governments, and FEMA in resolving issues in offsite preparedness planning. Each of the recommendations from the previous SALP Board o was addressed by the licensev during this assessment period. Cor-  : rective actions were evaluated by the NRC during routine inspections and observation of the two annual exercises, and improvement was , noted in each area. Dose assessment and projection, in particular, were noted as strengths in response facilities during the 1991 and 1992 annual emergency exercises. O Licensee management's approach to the resolution of technical issues appeared generally timely and thorough. During the assessment O

1 period, the licensee significantly upgraded the emergency urning siren system. The new primary system was completed, tested and l turned over to the county with 100 percent activation in September

O 1992. The upgrade provided several new capabilities such as an activation system which allows selective sounding of individual or groups of sirens as opposed to the entire system, and a siren feedback system which provides input to the county when a " runaway siren" sounds without intended activation.

I

O One EP exercise weakness was identified during the 1991 annual emergency exercise. The licensee's system for providing Protective i Action Recommendations (PARS) appeared excessively complicated and caused delay in the issuance of PARS. The system was not based solely on plant conditions as would be appropriate, but included coordination of PARS with offsite agencies. This delayed and O possibly biased the licensee's decision making. The appropriate emergency plan implementing procedure (EPIP) was revised to insure licensee independence in PAR decision making and was validated through training, drills and exercises. The system appeared to have l been effectively implemented during the 1992 annual exercise.

l

O There were no enforcement actions in the EP area during the assess-cent period. Notifications to the NRC and offsite agencies were i consistent with regulatory requirements. The licensee reported nine i unusual events to the NRC during the assessment period, including i three earthquakes detected at the site. The other events were a

! reactor coolant system (RCS) leak, a grass and brush fire near the lO site, a turbine stop valve failure, a sulfuric acid spill, radiation overexposure of two contractor employees, and a temporary loss of communications with the California Office of Emergency Services. All events appear to have been properly identified and analyzed in accordance with regulatory requirements. EP staffing was an apparent strength, and staff members appeared 9 conscientious toward accomplishment of their assigned duties. No significant changes occurred in the composition of the emergency response organization (ERO) during the :tssessment period. The licensee had a system to ensure that new ERO personnel were properly trained prior to assignment to emergency organization positions. O EP staff and emergency response positions were clearly identified; authorities and responsibilities appeared clearly defined; and key positions were filled as appropriate. Decision-making authority appeared properly delegated to ensure quick identification of and response to problems and changes. Emergency facilities continued to

be appropriately maintained and appeared ready for rapid activation.

The licensee provided adequate levels of dedicated staff to implement

O the programs and to interact appropriately with offsite agencies.

During the assessment period, the licensee implemented what appeared a to be a substantial change to the EP training program. Previously, the site and corporate headquarters had separate EP training programs i and responsibilities. The company-wide responsibility for EP

-O training management and accomplishment was shifted entirely to the site. A system was established to ensure that required training is 4

conducted and that training due dates are not exceeded, by linking accomplishment of EP training requirements to unescorted access privileges. To supplement and reinforce routine annual training, a O program of monthly integrated drills was conducted.

2. Performance Ratina Performance Assessment: Category 1 O 3. Board Recommendations The licensee should strive to maintain a consistent level of management oversight to continue and improve on the program quality achieved during this assessment period.

O E. Security

1. Analysis During this SALP period, approximately 4 percent of direct inspection effort was applied to the licensee's physical security and fitness O for duty programs. In addition to region based _ inspections, the resident inspectors also monitored implementation of this program as part of their routine inspection activities.

The previous SALP report rated the licensee's performance Category 2, Improving, for Security. Primary weaknesses identified in that O report focused on personnel access control to vital areas and failures of compensatory security measures. These weaknesses were significantly reduced during the current assessment period. In the-previous SALP report, the Board encouraged the licensee- to resolve a longstanding weakness in the CCTV alarm assessment capability, initially identified during a 1986 Regulatory Effectiveness Review. O. A significant equipment upgrade to incorporate a video capture system was installed during the current assessment period and has-largely eliminated this weakness. Some minor limitations remain with the video capture system and the licensee is actively exploring further equipment and/or procedural improvements. O The licensee's performance in the areas of physical security and fitness for duty appeared, on the basis of inspections conducted, event reports, and other observations and analysis, to be good in all assessment areas. Both program strengths (vital area barriers and armed response) and weaknesses (effectiveness of the audit program and the number of pending requests for security equipment modifica-O tion or maintenance) have been noted during the assessment period. Principal strengths in the licensee's security and fitness for duty programs included control of access to vital areas, the use of roving patrols dedicated to armed response (carrying carbines or shotguns, as appropriate, as well as side arms), and the availability of O Employee Assistance Programs for contractor employees. A major program upgrade to establish a search train at the intake structure protected area was completed during the assessment period. 'O

! A principal program weakne~ss was noted concerning the number of cited i and non-cited violations that could have been identified and 1 corrected by a stronger audit program. This indicated a need for 1 0 increhsed management attention to upgrade the audit program and make ! it more effective. I i Although the licensee has been aware of a large backlog of action j requests for maintenance or modification to security equipment, i little progress was seen in addressing this concern. This was also

O seen as a program weakness. Discounting action requests of an i administrative nature or otherwise having no direct effect on

! security activities, approximately 90 requests were identified as i being more than 90 days old, nearly half of which wure more than a j year old. A more effective audit program could have identified this { weakness. This further demonstrated the need for increased lO management attention. i l One Licensee Event Report dealing with safeguards matters (requiring i prompt reporting pursuant to 10 CFR 73.71) was issued and adequately i resolved during the SALP period. This report dealt with failure of I circuit boards in the alarm annunciation system, and prompted a full 1 0 replacement of the obsolescent components which is scheduled to be completed in the near future. However, technical issues discussed in two reports issued in January and December 1990, and dealing with backup power to communications equipment and vital equipment pro-tected by compensatory measures, respectively, remain to be resolved. O Enforcement actions during the assessment period included four viola-tions, which were resolved by appropriate corrective actions: one each related to access control at the main and intake structure protected areas, one violation related to protection of Safeguards Information, and one violation related to urinalysis testing of fitness for duty program personnel. Two weaknesses related to O fitness for duty and four non-cited violations dealing with vital area access control, communications, lighting, and protection of Safeguards Information were promptly corrected by the licensee. The licensee's loggable safeguards events were promptly and completely reviewed and reported as required. The root cause and O trend analyses of these events determined that most of the events were related to aging equipment scheduled for replacement by major hardware upgrades then underway. The frequency of occurrence has exhibited a decreasing trend as those projects have been completed. Licensee staffirg appeared effective in most areas, although the O identified long delays in resolving security related action requests may indicate a need for additional senior management support. Key positions have been identified and responsibilitie., are well defined. Decision making authority appears properly assigned to ensure prompt identification and response to program challenges. During the current assessment period, management implemented team development O workshops for all staff. This training showed significant promise in improving staff communications and cohesiveness. O

_ 13 _ O-The licensee's guard training and qualification program was well defined and implemented with dedicated resources. During this SALP period, the licensee initiated sophisticated contingency drills l ,O incorporating diversionary tactics and covert penetrations.

3. Board Recommendation

.O l Licensee management is encouraged to more effectively identify and address weak areas. More attention shoLld be given to improving the - effectiveness of the audit program and to reducing the number and age of outstanding maintenance requests.

O F. Enoineerina/ Technical Support
1. Analysis During the assessment period, NRC regional and Headquarters inspectors conducted a total of twelve inspections. Two of these O inspections were team inspections which addressed motor operated valves and shutdown risk management. The other inspections involved facility modifications, design changes, inservice inspection and testing, erosion / corrosion monitoring, eddy current testing of steam generator tubes, and procurement of a new emergency diesel generator.

The resident and project inspectors also conducted inspections in U this area. Review of Engineering and Technical Support activities accounted for approximately 15 percent of the totcl Diablo Canyon inspection effort. The last SALP assessment rated the licensee's performance in this ,O functional area Category 1. Improvements were recognized in Engi-neering involvement in plant operations and modification work, design basis reviews, setpoint reverification, vendor interface, personnel qualification and training. A particular strength was found in the commercial grade dedication program. Some weaknesses were noted in incomplete technical work and untimely identification and resolution O of problems due to a weak sense of ownership of plant problems. The Board recommended that the licensee provide emphasis on early identification, effective engineering involvement, and timely and thorough correction of plant problems. The licensee was encouraged-to continue building a strong interface between corporate and plant engineering groups, with corporate engineering taking a leadership .O role in the resolution of plant problems. Continuation of inns.3tive l corporate enginearing training programs was specifically encouraged. l During this SALP assessment period, the licensee showed continued l , high quality performance in this functional area. Strengths were . ( observed in a generally aggressive and thorough engineering attitude

O in resolving technical problems, an extensive erosion / corrosion conitoring program, eddy current testing of steam generator tubes, 7 assessment of probabilistic risks to the shutdown plant, and overall t

e I

1 O ~ I4 - i i i emineering invcivement in plant operational activities. The NRR l staff observed excellent quality in the technical content and presentation of licensee submittals, which included documents in o support of lice 1se amendment requests, corrective actions regarding operations and Licensee Event Reports, and responses to NRC bulletins and generic letters. Improvements were observed in timely problem identification, engineering involvement, and problem ownership. Minor weaknesses were noted related to procurement of the new l emergency diesel generator (EDG) and certain inservice inspection and  ; o testing activities. l Engineering involvement in resolving safety issues was generally timely. The mosi significant exception was Engineering's assessment of problems with containment fan cooler unit (CFCU) backdraft dampers t in early 1992. Additionally, resolution of Regulatory Guide 1.97  ; O issues was delayed by inadequate tracking of engineering actions, but the licensee later identified this weakness and pursued resolution in  ; an aggressive manner. Substantial improvement was displayed later in the SALP period in Engineering's timely resolution of CFCU damper - blade cracking. o Strong Engineering performance and initiative were evidenced in Engineering's evaluation of setscrew loosening on motor operated valve (MOV) actuators and the licensee's decision to examine the steam generator feedwater nozzles in response to problems observed at another facility. The feedwater nozzle examinations were extensive and used state-of-the-art techniques. The Engineering staff's O assessment of crack indications in both feedwater piping and in a ' safety injection tank penetration resulted in a conservative decision , to replace affected piping segments.  ; Proactive Engineering involvement was observed in the development of an extensive erosion / corrosion monitoring program. Despite extensive ' O involvement with the industry in the development of predictive analy- . tical computer programs, poor correlation between the quantitative t predictions and measured wear rates had been experienced by the litersee. The licensee's program exhibited a defense-in-depth  ! approach to compensate for recognized limitations in the state of the art. Although a program weakness in the measurement of pipe wall O thickness was noted, strong engineering ownership of the program compensated for this minor weakness. l Throughout the SALP review period, the licensee demonstrated an aggressive engineering attitude in technical problem resolution. For ' example, the licensee instituted a supplemental program that is the o first surveillance program in a U. S. commercially coerated reactor vessel to investigate the effect of annealing and reirradiation on its reactor vessel beltline materials. 3 Another example of aggressive engineering was resolution of the long-term seismic program. The licensee performed a detailed analysis to 0-demonstrate that adequate seismic margins exist for the structures and equipment which could be affected by increased ground motion in certain frequency ranges at the Diablo Canyon site. O

I , The licensee also developed and implemented an effective outage risk assessment plan which was found superior to other plants which were . inspected. The technical support provided for the outage risk I 3 assessment plan was excellent. l The engineering program developed for eddy current testing (ECT) of  ! steam generator tubes was observed to be a high quality program incorporating current technology and industry guidance. However, a weakness was noted in that engineering guidelines for ECT data 3 analysis and defect acceptance criteria, although adequate, were not controlled through the use of formal plant procedures. Specific strengths noted in engineering activities were as follows:

  • The motor operated valve (MOV) program was found to be 9-aggressive and conducted in a well integrated manner. A minor weakness was identified in the lack of timely determination of operability following testing, due to the complexity of the engineering evaluation required to evaluate the test data.

A strong safety perspective was evident in the development of 9' engineering programs to resolve emerging technical issues. The programs were implemented with priority on safety significance. Quality assurance involvement was evident in the implementation of engineering programs. 3

  • Design change packages for the installation of a new emergency diesel generator were generally thorough and complete, although minor housekeeping and cleanliness deficiencies were observed.

Four Severity Level IV violations, one Level V violation and one non-cited violation were identified. The violations were minor in nature 3 and did not evidence programmatic breakdowns. The low number of engineers and lack of clear goals for the plant's System Engineering staff was a concern earlier in the SALP period. The licensee has since increased the staff and clarified the goals for this group, and some improvement has been observed. O The commercial grade dedication of the sixth emergency diesel generator (EDG) presented unique challenges to the licensee's engineering and procurement activities. The Region and NRR Vendor Branch identified weaknesses in the quality of the procurement and  ! commercial grade dedication of the new emergency diesel generator. 3 However, the licensee's root cause investigation was candid and thorough. Also, although most problems encountered during testing of the sixth EDG were found to have been documented and resolved, the test program did not require formal documentation of problems. This weakness was promptly corrected after identification by the NRC. e Inservice inspection and testing activities were found to comply with approved programs.

Safety Assessment /0uality Verification l 1. Analysis j ) Evaluation of this area was based on both region-based and resident . inspections. Review of Safety Assessment / Quality Verification activities accounted for about 26 percent of the total Diablo Canyon i inspection effort. p The last SALP assessment rated the licensee's performance in this i area Category 1. Strengths were noted in the implementation of Event l Investigation Teams (EITs). Weaknesses were noted in resolving problems in a timely manner and in occasional lack of management i aggressiveness in dealing with problem areas. The licensee was  : encouraged to provide core management involvement in timely problem  ! J identification and root cause investigation, particularly in the area y of repeat problems. t During this SALP assessment period, the licensee generally showed l improved performance in this area. Management was more aggressive j and timely in dealing with problems than during the previous period, . and Safety Assessment / Quality Verification performance by line and D ' quality organizations showed continued improvement. A weakness was noted in the identification and correction of precursors of  ! potentially significant problems. i l l- A significant strength was the aggressive implementation of programs i to improve control of safety system availability during operating and I shutdown modes. These programs were implemented at all levels of the l licensee's organization. Plant design changes were also implemented to reduce risk, resulting in improved safety performance and safety system availability.

O SALP period was insufficient QA involvement. Some improvement was observed in the latter portion of the SALP period. Audits required by Technical Specifications were adequate and appropriate. l l Additional audits performed as Quality Assurance initiatives showed

' significant technical depth, and identified weaknesses in complex technical areas not typically reviewed by quality organizations. A i 10 noteworthy improvement in QA effectiveness was evidenced in the increased use of surveillances, which are brief audits in specific areas of concern. These audits have allowed rapid focus of QA oversight in problem areas, which resulted in more timely management attention, root cause evaluation, and corrective action. , O Safety groups continued to be very strong in safety focus and depth of technical assessment. The Onsite Safety Review Group identified problems consistent with issues of higher safety significance. fianagement support of this group was adequate. The fiuclear Safety Oversight Committee improved during this assessment period as a result of focus on higher level concerns, and the addition of non-O licensee members. The Plant Safety Review Committee continued to be very strong, providing significant safety insight and conservative

  • decision making.

fluclear Operations Support (f;05), which is not by charter a quality oversight group, performed several reviews and audits during this  ! O assessment period which were instrumental in identifying and  ; correcting problems in interfaces between licensee organizations. ' These 140S reviews and audits resulted in several improvements in the overall implementation of plant safety functions. During this assessment period the NRR staff reviewed a large number  ! O of safety analyses performed by the licensee. The licensee's  : submittals demonstrated a clear understanding of safety issues and a conservative approach to technical problem resolution. The submit-  ; tais for license amendment requests were technically icequate and generally complete. Also, several of the licensee's submittals contained probabilistic risk assessment (PRA) analyses which were of l O high quality (the PPA technique requires considerable effort by the ' licensee, and when properly used, adds to the basis for approving  ; proposed changes). The licensee's replies to NRC generic letters and ' bulletins were also timely, responsive and of generally high quality. l Throughout the SALP review period, the licensee consistently and  ! O systematically addressed operability concerns in an aggressive nanner, and made appropriately conservative decisions until each concern was resolved. Licensee management kept the f1RC well informed of initial concerns as well as their followup plans for resolution. An increased number of personnel errors were observed in several O functional areas at the beginning of the SALP period. This number  ; was reduced by about half during the remainder of the period as a i O ' i

J result of an effective human performance enhancement program and aggressive management involvement at all levels of the organization. s The licensee's program for assessing industry events was strong. A few vulnerabilities were identified and corrected promptly. Several programs were enhanced as a result of implementation of lessons learned from the industry. While the licensee typically has been aggressive in problem resolu-tion, there have been isolated examples of insufficient aggressive-ness in pursuing safety issues. For example, based on the review of licensing submittals requesting relief regarding pumps and valves, the licensee's a proach to the resolution of inservice testing program issues required amplifying information and in some cases were not technically justified. U Five Severity 1.evel IV violations were cited in this area, one for failure to correct reverse rotation of containment fan cooler units, and the others for failure to correct repeated problems of a lower safety significance in various functional areas. " A few weaknesses were observed. For example, in three cases, pre-cursors of plant problems occurred without being identified as such. An example of one of these three instances was an unplanned turbine speed-u" event, corrected by operators, which had two precursors which were not identified and corrected. In each case, the more significant problem occurred because the precursor had not been

  '      adequately addressed. Another weakness was that the guidelines used to trend root causes of problems were imprecise, in that root causes of problems could be assigned to more than one area.

In conclusion, the performance of the licensee's line organization is very streng in the assessment of safety and assurance of quality.

'g       Independent safety groups, although already strong, showed additional strength during this assessment period. The Quality assurance organization's performance was not as strong as the line organiza-tions, but was above an adequate level.

brief power curtailments for maintenance and testing activities, except as  ; follows:  ; On July 5,1991 an unplanned start of engineered safety features (ESF) , equipment occurred when a licensed operator inadvertently actuated the l wrong solid state protection system test switch. The control room operators promptly returned all actuated equipment to normal status, t O On March 6,1992 a plant trip occurred due to the loss of main feedwater pump 1-1. The cause of the trip was traced to a faulty fusible link in an i inverter. Unit I was restarted on March 9, 1992 after a new inverter was installed for feedwater pump 1-1 and fusible links for feedwater pump 1-2 i were inspected. Unit I reached 100% power on March 10, 1992. ' O On April 25, 1992, while conducting maintenance on main feedwater pump 1-1, vacuum in the condenser was lost, causing the main turbine and , reactor to trip. The primary cause was attributed to inadequate instruc- l tions, which allowed a vacuum pump to be started before its seal water , isolation valve was opened. Also, condenser vacuum pump suction line ' check valve Cf4C-1-747 was observed to leak excessively when the condenser O vacuum pump suction valve was opened. Unit I was restarted on April 27, , 1992 after evaluation of the event and correction of the cause of the i trip. Full oower was reached on April 28, 1992. i On July 24, 1992, after observing excessive flow noise from main turbine j O governor valve number 4, the licensee closed the valve, resulting in Unit 1 operating at 98% power. On Ser'e..ber 17, 1992, Unit I shut down for a scheduled 63-day refueling ' outage. The shutdown was complicated by spurious reopening of a main  : turbine stop valve and two governor valves, which caused the turbine to O accelerate from 1100 RPM to 1870 RPM. A few hours later, during the cooldown, reactor coolant system (RCS) pressure rose above the 350 PSI setpoint. The system responded as expected, with the power operated relief valve opening and relieving pressure. On flovember 9,1992, Unit I completed its fifth refueling outage. The  ! unit reached 100% power on fiovember 11, 1992. O On December 23, 1992, an operator observed fragments of a fastening device on the ground. Followup investigation revealeda ' partially melted neutral -

         ,  line connector on a main transformer. The licensee curtailed power to 10%        -

and separated from the grid, fixed the connector and inspected all similar i O connectors, and returned to 100% power.  ; i O

O brief power curtailments for maintenance and testing activities, except as
follows-i  !

j On August 31, 1991 Unit 2 shut down for its fourth refueling outage about  ; 2 nin days early because of an unisolable leak in the charging system. The ~ ,O leak had been increasing since its discovery on August 13, 1991. The leak had not yet reached its Technical Specification limit at the time of

shutdown. Unit 2's shutdown marked 482 d ys of continuous operation at power, a new world record.

4 On October 20, 1991, Unit 2 achieved criticality, marking the shortest j refueling outage in Diablo Canyon history. Full power was reached on  : 50 October 31, 1991. l

t On February 16, 1992, during a power curtailment to 50% for condenser cleaning, the Unit 2 reactor experienced an exaggerated quadrant power .

! tilt ratio as a result of slightly different efficiencies of the secondary ! loops. The licensee decreased power below 50%, the level below which the

O quadrant power tilt action statement does not apply. The licensee also j entered the action statement, as a conservative measure. During curtail-4 4

ment operations, the power tilt decreased due to xenon burnup, and did no'. l recur until the following curtailment below 50% power for condenser clean- t ing on March 14, 1992. During this occurrence, the licensee repeated the earlier process, and entered the action statement. Upon power ascension,  ; O the power tilt decreased to normal, and the licensee exited the action statement. On March 23, 1992, Unit 2 was shut down to investigate a failed turbine  ! stop valve. The licensee disassembled the failed stop valve and found O that the nut nich secures the valve disk to the swing arm had disengaged,  ! allowing the disk to separate and partially block main steam lead number 2. Unit 2 was returned to power on March 28, 1992 after the failed turbine stop valve was repaired and the other three Unit 2 turbine stop , valves were verified to be properly assembled. ' B. Inspection Activities ' O Fifty routine and special inspections were conducted during this assessment period (July 1991 through December 1992), as listed below.
