EXECUTIVE SUMMARY

Duane Amold Energy Center

NRC Inspection Report No. 50-331/98003(DRP)

This inspection report included resident inspectors' evaluation of aspects of licensee operations,

engineering, maintenance, and plant support.

Operations

. The overall conduct of operations was professional as demonstrated by the rigorous use

of procedures and thorough shift turnovers. (Section 01.1)

. An operations shift supervisor did not take a generic approach when presented with

information regarding a suspect condition of a hydraulic control unit (HCU) nor did he

question the operability of the HCU. (Section 01.2)

. Operations personnel displayed a lack of attention to detail by unknowingly repositioning

an HCU solenoid housing during work activities. This resulted in several HCUs being in a

suspect condition. (Section O1.2)

. A suspect HCU condition was not identified by licensee personnel during plant tours.

(Section 01.2)

Maintenance

. The inspectors identified several examples of the licensee's failure to comply with the

procedure for restraining transient equipment or materials in Seismic Category I areas.

This resulted in a violation. (Section M1.3)

. The licensee promptly resolved emergent equipment material condition issues that were

identified during the inspection period. These emergent aquipment issues included a

steam leak in the offgas recombiner vault, a water leak from the high pressure coolant

injection pump, failed radiation monitors, and a failed pressure switch in the reactor

protection system. All of these equipment protdems were resolved well within the

associated Technical Specification allowable outage times. Personnel from the

engineering and maintenance departments provided good support and exhibited good

teamwork in resolving the issues. (Section M2.1)

Enaineerina

. Software support personnel installed new process computer software without consulting

with operations personnel and without fully evaluating the effect on plant monitoring

equipment. This resulted in a challenge to the operating crew when multiple APRM

comparison alarms were received and reactor power was reduced until the reason for the l

alarms could be determined. (Section E1.1)

Report Details

Summary of Plant Status

The plant began this inspection period operating at 100 percent power and remained at or near

full power for the remainder of the period. Exceptions to this included scheduled down power

evolutions for planned testing activities, control rod sequence exchanges, load line adjustm3nts,

and, as detailed in Section E1.1, a momentary unscheduled power reduction due to operator

action in response to numerous plant process computer average power range monitor (APRM)

comparison alarms.

1. Operations

01 Conduct of Operations

O1,1 General Comments (71707)

a. Inspection Scope

The inspectors followed the guidance of Inspection Procedure 71707 and conducted

frequent reviews of plant operations. This included observing routine control room

activities, reviewing system tagouts, attending shift turnovers and crew briefings, and

performing panel walkdowns.

b. Observations and Findinas

The conduct of operations was professional. The inspectors observed rigorous use of

procedures and thorough shift turnovers. Overall, emergent equipment issues were

promptly addressed and conduct of operations was appropriately focussed on safety.

c. Conclusions

The overall conduct of operations continued to be professional, with an appropriate focus

on safety as demonstrated by the rigorous use of procedures and thorough shift

tumovers.

01.2 Conduct of Operations Personnel Reaardino Condition of Hydraulic Control Units (HCU) ,

I

a. Inspection Scope

The inspectors reviewed licensee corrective actions in response to a failed HCU (26-39)

accumulator high water level switch and identified a potential operability concern with an

adjacent HCU (30-31). Interviews were conducted with operations personnel.

b. Observations and Findinas

As discussed in Section M1.2 of this report, NRC inspectors reviewed maintenance

activities performed to replace a failed HCU accumulator high water level switch. On

February 22,1998, NRC inspectors identified an operability concern with the adjacent

HCU (30-31). The inspectors found that the solenoid housing on the directional control

!

.

.

valve (V-121) was positioned so that its electrical cannector and/or cable would interfere

with the limit switch actuator of the inlet scram valve (V-126).

The inspectors immediately discussed the finding with a licensed operator who was in the

reactor building. The operator indicated that the solenoid housing was designed to pivot

or swivel. The operator theorized that the solenoid housing was most likely bumped and

moved forward while operations personnel worked to manually isolate the adjacent HCU.

The next morning, the inspectors visually assessed the remaining HCUs and identified

three additional examples of solenoid housings and/or cables that were in contact with

the limit switch actuator of the inlet scram valve. Through interviews, the inspectors

discovered that the operator had discussed the issue the previous day with the

operations shift supervisor (OSS). The OSS concluded that the condition was isolated

due to work performed on the adjacent HCU. Also, the OSS did not question whether the

HCU was operable in this condition. The inspectors were concemed that the OSS did not

take a generic approach when presented with the issue, nor did he question whether the

HCU was operable.

The inspectors informed the operations shift manager (OSM) of the three additional

examples identified. Operations personnel, led by the OSM, visually assessed the HCUs.

The OSM and/or operations personnel, under OSM guidance, moved the solenoid

housings away from the inlet scram activators. The OSM and NRC inspectors discussed

HCU operability concerns. The OSM contacted the system engineer and initiated Action

Request (AR) 980472.

The system engineer, with the assistance of General Electric (GE) representatives, i

performed an operability determination and concluded that the four HCus in question

would have performed their safety function. Section E1.2 of this inspection report

provides further information regarding the HCU operability determination.

The inspectors identified through interviews that all 89 HCUs were isolated during the

September through October 1996 refuel outage. Therefore, if the solenoid housings had

been unknowingly mispositioned during the manipulation of HCU isolation valves, the

three additional examples identified may have existed since October 1996. The

inspectors were concerned that the issue was not identified previously by licensee

personnel during plant tours.

c. Conclusions )

1

Operations personnel demonstrated a lack of attention to detail by unknowingly

repositioning an HCU solenoid housing during work activities. This resulted in several i

HCUs being in a suspect condition. Additionally, the OSS did not take a generic

approach when presented with the suspect HCU condition report by an operator or

question the operability of the HCU. The suspect HCU condition was also not identified

earlier by licensee personnel during plant tours.

01.3 Control Room Staff Below the Technical Specification (TS) Minimum Reauirements

Licensee Event Report (LER) 98-01 (71707)

a. Inspection Scope

The inspectors reviewed information regarding the licensee's failure to maintain minimum

control room staffing requirements in accordance with TS 6.2.2.2.d. Interviews were

conducted with licensee staff.

b. Observations and Findinas

The inspectors verified through interviews that the on-duty shift technical advisor (STA)

was permitted by operations management to leave the site due to a family medical

emergency. Arrangements were made with the on-coming STA to arrive onsite earlier

than scheduled; however, for one hour and eleven minutes no STA was onsite. This

resulted in an operational condition prohibited by TS 6.2.2.2.d, which required an STA to

be onsite at all times when there was fuelin the reactor. The licensee did not plan to

take any corrective actions for this issue; however, in the future, when implemented, the

improved TSs will allow the shift crew composition, including the STA, to be less than

minimum for a period not to exceed two hours to accommodate the unexpected absence

of on-duty shift crew members.

The failure to maintain a minimum operating crew at all times when there was fuel in the

reactor was a violation of TS 6.2.2.2.d. This was considered a non-cited violation in

accordance with Section IV of the NRC Enforcement Policy (50-331/98003-01(DRP)).

02 Operational Status of Facilities and Equipment

O2.1 General Plant Tours and System Walkdowns (71707)

The inspectors followed the guidance of Inspection Procedure 71707 in walking down

accessible portions of several systems:

. Standby diesel generators

. High pressure coolant injection (HPCI)

. Standby gas treatment system

Equipment operability, material condition, and housekeeping were acceptable in all

cases. Several minor discrepancies were brought to the licensee's attention and were

corrected. The inspectors identified no substantive concerns as a result of these

walkdowns.

07 Quality Assurance in Operations

O7.1 Licensee Self-Assessment Activities (71707)

During the inspection period, the inspectors reviewed multiple licensee self-assessment

activities, including:

.

Safety committee meeting

  • Action request screening meeting

.

Quality assurance quarterly assessment

The inspectors did not identify any problems or concerns with the licensee's self-

assessment activities.

!

07.2 Action Request System Review '

a. Inspection Scope

The inspectors reviewed the documentation methods used in the Action Request (AR)

system process. The evaluation included a review of procedure implementation and AR

records and discussions with licensee personnel.

b. Observations and Findinas

'

The inspectors reviewed Administrative Control Procedure (ACP) 114.5, " Action Request

System," Revision 12, which described the methods used for documenting potential

problems and the AR process. This procedure described the use of ARs for problem )

identification and tracking of problem resolution. The procedure also indicated that an AR I

would be categorized as either Level 1,2,3,4, or 5 based on the importance and priority {

of the problem. Level 1 ARs were used to document the most severe and highest priority J

problems while Level 2,3,4, and 5 ARs documented problems of decreasing importance

and priority. Levels 1 through 3 required root cause investigations and Level 4 and 5 ARs

did not.

The inspectors evaluated the number of ARs written and made a cursory review of the

type of problems documented and determined that the threshold for writing ARs was  ;

appropriate. A representative sample of all ARs was also reviewed in detail. No  !

concems were identified.

1

c. Conclusions

The AR system was being appropriately used for identifying issues and tracking of

problem resolution. The ARs reviewed adequately documented the licensee's evaluation

of potential problems.

08 Miscellaneous Operations issues (92700)

08,1 (Closed) Licensee Event Report (LER) 50-331/97-13-00: Inoperable Primary

Temperatures During HPCI System Testing. The inspectors had raised concerns with the

temperature rise in the suppression pool during routine HPCI surveillance testing The

inspectors reviewed licensee documents and determinod that the suppression pool

temperature response was consistent with design documents. The inspectors also

verified that TS requirements were met. The inspectors had no further concerns. This

item is closed.

M1.2 Appropriate Corrective Actions for Failed HCU Accumulator Hiah Water Level Switch l

l

a. Inspection Scope (62707)

The inspectors reviewed maintenance activities performed to replace a failea HCU

accumulator high water level switch. Interviews were conducted with maintanance and

operations personnel.

b. Observations and Findinas

The inspectors performed a visual assessment of completed work activities after the

Instrument and Control technician replaced an HCU accumulator high water level switch.

The ir'spection was performed shortly after the level switch was replaced and the

associated control rod was considered operable. The HCU isolation valves were verified

to be in the proper position to consider the HCU operable. However, the inspectors

identified a potential operability concem with the adjacent HCU. The solenoid housing of

the directional control valve (V-121) was positioned so that its electrical connector and

cable could interfere with the limit switch a':tuator of the inlet scram valve (V-126).

Further information regarding this finding is detailed in Section 01.2.

c. _ Conclusions

The inspectors concluded that licensee corrective actions were appropriate following the

identification of a failed HCU accumulator high water level switch. However, the

insnactors found an operability concern with the adjacent HCU.

M1.3 Unacceptable Restrainina Methods for Transient Eauipment or Materials Used in the

Plant

a. Inspection Scope (62707)

The inspectors reviewed licensee corrective actions for improperly restraining unstable

equipment in Seismic Category I areas. Interviews were conducted with licensee

personnel, applicable procedures were reviewed, and routine plant tours were conducted.

The inspectors reviewed Administrative Control Procedure 1408.9, " Control of Transient

Equipment / Materials," Revision 3.

b. Observations and Findinas

I

As documented in NRC IR No. 50-331/98002, the inspectors found two examples of

temporary equipment that was not restrained in accordance with plant procedures. The

licensee responded by implementing corrective actions which included properly I

restraining the equipment identified by the inspectors and initiating AR 980296 to increase

staff awareness on appropriate methods for securing temporary equipment.

Administrative Control Procede e 1408.9 provides guidance to plant personnel on the use )

and storage of transient equipment or materials used in Seismic Category I areas in the {

plant. Section 3.7(2) of ACP 1408.9 provides plant personnel with a list of unacceptable j

plant elements to be used for the restraint of unstable equipment, including conduits, I

small bore pipe (less than four inches), heating, ventilation, and air conditioning (HVAC)

9

.

hangers, and safety-related equipment. The inspectors found several examples where

unstable trancient equipment or materials were restrained to unacceptable plant

elements. Some examples included:

On February 10,1998, a rolling cart was found restrained to a conduit in the

control room back panel area.

  • On February 13,1998, electrical panel doors were found restrained to a conduit 'in

the reactor recircu!ation motor generator room.

.

On February 20,1998, a ladder and two boxes of light bulbs were found

restrained to a conduit in the intake structure.

. On February 23,1998, a ladder was found restrained to a conduit in the Crack

Arrest Verification (CAV) area of the reactor building.

-

On February 27,1998, a rolling cart was restrained to small bore piping (less than

four inches) in the control building chiller area. This example was of greater

concern than the other examples because earlier in the day operations personnel

found the cart restrained to a conduit. The individual recognized the improper

restraining method used; however, in correcting the problem, he restrained the

cart to it small bore piping.

  • On Ma. 2,1998, two rolling carts, which included the cart identified on

Febmary 27, were restrained to control building chiller safety-related piping. This

example was of concem because it was repetitive.

.

On March 2,1998, two HEPA filter units mounted on rolling carts were restrained

to HVAC hangers above the control rod drive repair room and close to safety-

related steam tunnel temperature monitors. The licensee was informed and

properly restrained the equipment that day.

On March 6,1998, the same two HEPA filter units restrained to HVAC hangers

that were found on March 2 were again restrained to HVAC hangers.

The inspectors reported the improperly restrained transient equipment and materials in

Seismic Category I areas to operations or maintenance personnel as the conditions were

identified. The transient equipment and materials were either properly restrained or l

removed by licensee personnelin order to comply with procedure requirements.

The inspectors interviewed training department personnel to determine if employees had

been provided adequate instructions regarding the control of transient materials or ,

equipment in the plant. The inspectors concluded that adequate training was provided l

during general employee training sessions.

The inspectors interviewed several plant employees to determine their general knowledge i

level of requirements for proper restraining methods of transient materials or equipment. l

Personnel were generally aware of the requirement to restrain transient equipment and J

materials; however, the many identified examples of improper restraining methods j

indicated that personnel may not fully understand why transient materials or equipment

I

10

.

,

,

need to be restrained. Also, in some instances, ACP 1408.9, provided complex guidance

to personnel on proper restraint methods. Previous examples of improper restraining

methods used to secure transient equipment or materials were identified and

documented in IR No. 50-331/98002.

Failure to follow administrative procedure ACP 1408.9 is a violation of 10 CFR Part 50,

Appendix B, Criterion V (50-331/98003-02 (DRP)) as in the attached Notice of Violation.

Conclusions

The inspectors identified several examples of improperly restrained transient equipment

or materials in Seismic Category 1 areas. Previous examples of improper restraining

methods used to secure transient equipment or materials were identified and

documented in IR No. 50-331/98002.

M2 Maintenance and Material Condition of Facilities and Equipment

M2.1 Plant Material Condition

a. Inspection Scope (62707)

The inspectors reviewed several emergent work items to ensure appropriate operability

evaluatiors were performed, TS were met, repairs were made, and root causes were

determined where appropriate.

b. Obseavations and Findinas

The following emergent equipment issues were identified d9rin': the inspection period:

.

On February 22,1998, security personnel on fire watch rounds noticed higher

than normal temperatures and high humidity conditions in the RCIC area.

Operations personnel were promptly notified and a steam leak was identified in

the offgas recombiner vault. The leak.was isolated to the standby pressure

control valve (PCV 41508) which supplied steam to the "B" offgas preheater. The

line was isolated and the component was repaired. The system was tested

satisfactorily later the same day.

+ On February 12,1998, increased seal water leakage was identified on the HPCI

main pump casing after performing HPCI quarterly surveillance testing. The

licensee entered a 14-day LCO and completed repairs within 2 days

(CMAR A34492).

  • On March 9,1998, while performing testing in accordance with STP 3.3.4.2-01,

" Anticipated Transient Without a Scram - Recirculation Pump Trip / Alternate Rod

insertion (ATWS-RPT/ARI) Reactor High Pressure Calibration," pressure

switch PS45938 failed to close within the specified pressure range.

CMAR A47223 was initiated and pressure switch PS45938 was replaced the next

day.

11

.

.

.

.

On March 10,1998, while performing STP 42H004 A, "Kaman Extended Range

Effluent Radiation Monitors Annual Calibration (Turbine Building Exhaust Stack),"

a detector for one of the Kaman monitors failed to perform its intended function.

The licensee entered a three-day LCO to establish alternate sampling and a

seven-day LCO for completing repairs. CMAR A47251 was initiated and repairs

were completed within two days. The LCOs were subsequently exited.

c. Conclusions

The licensee promptly resolved emergent equipment material condition issues that were

identified during the inspection period. These emergent equipment issues included a

steam leak in the offgas recombiner vault, a water leak from the high pressure coolant

injection pump, failed radiation monitors, and a failed pressure switch in the reactor

protection system. All of these equipment problems were resolved well within the

associated TS allowable outage times. Personnel from maintenance and engineering

departments provided good support and exhibited good teamwork in resolving the issues.

E1 Conduct of Engineering

E1.1 Inadeauate Communications Recardina Software Chanae to Plant Process Computer

Challenaes Operatina Crew

a. Inspection Scope (37551)

The inspectors reviewed information regarding a plant process computer software

change made without prior notification to operations personnel which resulted in

challenging the operating crew. Interviews were conducted with engineering and

operations department personnel. The inspectors reviewed ACP 102.14, " Software

Quality Assurance Program," Revision 5.

b. Observations and Findinas

The inspectors interviewed system engineering and software support personnelinvolved

in the software change. The system engineering personnel stated that the software

program was enhanced to compare individual APRM power levels to an average of the

summation of APRM power levels, rather tinn comparing each individual APRM to other

individual APRMs.

On March 3,1998, the software enhancement was installed without notifying the

operations staff and immediately the operating crew received plant process computer

APRM comparison alarms. The inspectors determined that software support personnel

assumed the revised software would not affect plant process computer data. When the

enhanced software was installed, the APRM comparison alarm point was changed from

five percent to 1.25 percent The operating crew responded conservatively and reduced

reactor power until the cause of the alarms was determined. Reactor power was

increased to 100 percent within one hour after the software change. The inspectors were

concemed that plant process computer software changes were initiated without any prior

12

.

.

notification to operations personnel which resulted in a challenge to the operating crew.

The licensee held a fact finding meeting with involved personnel to determine the root

cause.

The operations supervisor discussed his expectations that operations personnel be

informed of software changes before their installation. The inspectors noted that the

licensee was revising ACP 102.14 to reflect the need to inform users of software

changes.

c. Conclusions

Software support personnel installed new process computer software without consulting

with operations personnel and without fully evaluating the effect on plant monitoring

equipment. This resulted in a challenge to the operating crew when multiple APRM

comparison alarms were received and reactor power was reduced until the reason for the

alarms could be determined.

E1.2 Operability Determination for Suspect HCUs

a. Inspection Scope

The inspectors reviewed the licensee's operability determination performed after four

HCUs were identified by the inspectors that had the insert directional control valve

solenoid housing and associated cables in contact with the position plate of the insert

scram valve. The inspectors conducted interviews with system engineering, operations,

and licensing personnel.

b. Observations and Findinas

On February 22 and 23,1998, the inspectors identified four HCU insert exhaust solenoid

housings and associated cables that were in contact with the position plates of the inlet

scram valves. The licensee performed an operability evaluation to determine if the HCUs

would perform their intended function. The licensee concluded that the HCUs would have

performed their safety function. Although unlikely, the worst consequences would have

been that: (1) the directional control valve solenoid would be displaced when the scram

valve actuated, resulting in a small primary containment leak which could be manually

isolated; and/or (2) the directional control valve wiring would be damaged, causing an

electrical short in the reactor manual control system, thereby disabling the operating

crew's ability to insert or withdraw any of the control rods using manual controls.

Corrective actions were taken to secure (tie wrap) the solenoid housing cables to the

HCU support frames, thus preventing the solenoid housings from swiveling. The

inspectors confirmed corrective actions were taken for all 89 HCUs. Also, the lierasee

initiated a request to schedule an inspection of the HCUs every year to verify the solenoid

housing cables were secured and that no solenoid housings and/or cables were in

contact with the insert scram valve position plate. The inspectors had no concerns

regarding the operability determination.

The system engineer identified that GE Service Information Letter (SIL) No. 3, issued

July 31,1973, discussed the subject problem and recommended specific corrective

actions to be taken. The licensee was unable to find supportive documentation to

13

l

!

.

.

e

determine if a response was made to the SIL. Tne inspectors were concerned that

recommended long term corrective actions were not previously implemented to prevent

this condition.

c. Conclusions

The inspectors had no concems regarding the HCU operability determination. Immediate

corrective actions and long term correctiv' actions were instituted when the condition

was discovered. The inspectors were concemed that recommended long term

corrective actions were not implemented as recommended in GE SIL No. 3 to prevent

this condition.

IV Plant Support

R1 Radiological Protection and Chemistry Controls

R1.1 Good Radiation Protection Support for HPCI and RCIC Surveillance Tests

a. Inspection Scope (71750)

The inspectors reviewed the adequacy of radiological controls in accordance with

inspection Procedure 71750. This included observing radiological control work practices

supporting the February 11,1998, HPCI surveillance test and the March 6,1998, RCIC

surveillance test.

b. Observations and Findinas

On February 11,1998, the inspectors observed the pre-test briefing and portions of

Surveillance Test STP 45D001-0, "HPCI System Quarterly Operability Test." On

~ March 6,1998, the inspectors observed the pre-test briefing and portions of Surveillance

Test STP 45E001-0, "RCIC System Quarterly Operability Test. The inspectors observed

that radiation protection personnel provided a thorough pre-test briefing and informed

individuals of potential changing radiological conditions during the test and the necessary

precautions to be taken. Radiation protection personnel provided good support in the

field during the test and properly controlled areas where radiation exposure rates

increased.

c. Conclusions

Radiation protection personnel provided good support during the conduct of HPCI and

RCIC surveillance tests.

F1 Control of Fire Protection Activities

F.1.1 Acoropriate Fire Watch Activities

a. Inspection Scope (71750)

The inspectors evaluated fire watch activities conducted in hot work areas to determine

the licensee's adherence to its fire plan. Also, the inspectors observed security personnel

performing routine fire watch rounds to determine the adequacy of their fire watchs as in

relationship to the licensee's fire plan.

b. Observations and Findinas

The inspectors observed that fire watch personnel performed duties appropriately. The

inspectors verified through interviews that fire watch personnel were knowledgeable of

where hot work was conducted and the need to visually assess the hot work area for a

period of time after work was performed. The inspectors had no concems.

As discussed in Section M2.1, a fire watch on rounds identified higher than normal

temperature and high humidity conditions in the RCIC area. This was promptly

communicated to the control room which enabled the licensee to quickly respond to the

problem.

V. Manaaement Meetinas

X1 Exit Meeting Summary

The inspectors presented the inspection results to members of licensee management at the

conclusion of the inspection on March 17,1998. The licensee acknowledged the findings

presented. The inspectors asked the licensee whether any materials examined during the

inspection should be considered proprietary. No proprietary information was identified.
