INSERVICE INSPECTION PROGRAM UNIT 2 SALEM GENERATING STATION INTRODUCTION:

Commencing with the date of Commercial Operation, and for the duration of first 120 month inspection interval, the Inservice Inspection Program for Class 1, 2 and 3 components and systems is based on Section XI of the ASME Boiler and Pressure Vessel Code, 1974 Edition and Addenda through Summer 1975.Section XI requirements are augmented by cer-tain special requirements as defined in the Salem Unit No. 2 Technical Specifications, Sections 4.4.5.0, 4.4.10.1 and 4.4.10.2 for examination of steam generator tubing, reactor coolant pump flywheels and steam generator channel head cladding.

Repairs in the pressure retaining bcundary of systems and components falling within the scope of this program will be made in accordance with Division 1 of Section XI, or, if such repairs are not specified in Division 1, repairs will be made in accordance with the provisions of the Code appli-cab 1C to the construction of the component.

SCOPE:

Class 1, 2, and 3 components and the methods of examination for each component are listed in Tables 1, 2 and 3 respec-tively. Examination boundaries are defined on modified system piping diagrams entitled "ISI Boundary Diagrams" in Attachment 2. The schedule for examination of specific components is described in the long term inservice examination plan.

REQUEST FOR RELIEF:

Relief is requested from certain requirements of Section XI that hav3 been determined to be impractical because of accessiblity and design limitations established prior to issuance of the 1974 edition of the Code, and for other con-siderations. These requirements and the affected components are itemized in Attachment 1. In some cases, alternate means of testing are described. It is the position of PSE&G that the relief will not compromise the integrity of safety related components.

ATTACHMENT 1 ITEM 3 FOR WHICH RELIEF IS REQUESTED

1. . Bolts in Category B-G-1, except as-many as four bolts in each of four reactor coolant pumps, will be examined

' ultrasonically in place during the inspection interval. Those bolts which are inaccessible due to interference from structural members and piping will be examined at or near the end of the inspection interval All when the pumps are disassembled for maintenance.

bolts in Category B-G-2 will be e xamined visually during the inspection interval. If visual examination i

reveals indications of distress, the bolts will be removed for surface and/or volumetric examination.

2. Ultrasonic indications will be recorded at 50% of 3

reference level (DAC) unless suspected by the examiner to be other than geometric in origin, in which case

they will be recorded and investigated by a Level II or Level III Examiner if in excess of 20% of DAC. All indications above 100% DAC will be resolved as to their shape and identity by a Level II or Level III Examiner.

l Justification for departure from a 20% reference level evaluation criterion for all UT examinations is explained in detail in Attachment lA, prepared by i

Southwes" Research Institute as agents for PSE&G.

3. Ultrasonic examination of ferritic piping will be per-formed in accordcnce with Article 5 of Secti'n V of the ASME Boiler and Pressure Vessel Code with the exception  ;

that all indications will be recorded and evaluated as indicated in paragraph 2 above.

i- 4. Inaccessibililty for examination was identified during

' the Preservice Inspection and has been described in the

! Remarks column of Tables 1 and 2 of the SalemThose No. 2 Preoperational Baseline Examination Report.

items which could not be examined due to inaccessi-

' bility have been extracted from these tables and compiled into an abbreviated table which has been included as Attachment 1B for convenient reference.

Comments in these tables are necessarily brief.

Information in greater detail has been provided in the >

way of additional comments, also included as part of Attachment IC. Consideration of alternate methods are discussed and in some cases sketches are attached for greater clarity.

5. Welds having limited ultrasonic examinations are treated in the same manner and are' included in the -

tables and comments mentioned above. No distinction is 1

made between items having no accessibility and limited ,

i inspectability except in the nature of the comment.  ;

Detailed radiographic procedures for augmented or alternative examinations will be prepared at such time as the need arises in order to take advantage of the possibility of more advanced technology at that time. I

6. The holding time after pressurization and prior to commencement of visual examinations during pressure tests required by IWA 5000 of Section XI will be 10 minutes when insulation is removed. This procedure is presently specified in recently approved editions of Section XI and is considered acceptable practice for an exposed pressure boundary. The longer holding time required by the 1974 Edition of Section XI ecesents unnecessary exposure to radiation in an operating plant.

Title:

Comments Concerning the 20 Percent Versus 100 Percent Evaluation Level for Ultrasonic Examination of Nuclear Power Plant Piping Introduction I. The Nuclear Regulatory Commission (NRC) has asked several plant owners for detailed information to justify two things.

A. That a 20% reference level evaluation criterion is impractical and B. That a 100% reference level evaluation criterion will provide a level of safety comparable to the Section V code requirements (of evaluation at 20%).

D,iscussion II. Southwest Research Institute (SwRI) presents the following considerations on these two closely related questions, taking them in order:

A. The impracticality of recording / evaluation at 4

the 20% reference level.,

l 1. The welded joints in nuclear piping f requently contain code-allowable wall '

i thickness differences (12-1/2% of thickness) as well as allowable weld l' _.

'dropthrough and other conditions such as counterbore taper, crown, etc. These conditions can provide an extremely large

, number of geometric reflectors (with or without mode conversion) which produce ultrasonic examination (UT) indications greater than 2C% of the UT reference level (DAC) (see attached graph). Weld metal in stainless steel piping contains, in addition, reflectors due to metallurgical grain structure which can l

l also produce indications greater than 20%

i Attachment lA Page 1 of 9 P8035/05 1 I

_ .. . _ , _ __ , , . . , , . . . _ . _ - , . , _ . . _ . , . - _ . , _ . - _ . , _ _ , . - _ _ ~ . . ,

DAC. It appears that the incidence of geometric reflectors increases exponentially as the amplitude is reduced.

. 2. Two stress-corrosion cracks are known to have been missed by SWRI normal examination techniques. However, they were not missed because of lack of

' detectability; indications of 141% and 159% DAC were obtained from these stress-corrosion cracks in'the HAZ. They were'not identified because of thr2 large i

4 number of equally high amplitude geometric indications from the adjacent i root area-which, in effect, masked the test-data to preclude identifying these cracks. Reducing the recording level to i

20% will cause this problem to exist on a much larger scale in that the tremendous increase in ' recorded indication data will obscure real flaw indications. .

3. During the performance of inservice inspections, significant radiation

. exposure is being experienced by all the inservice examination personnel. In SwRI's experience the examination staff receives essentially all of the legally allowed radiation exposure when recording 50% DAC data. To evaluate and record 20%

data would require that the personnel spend several times as much time in a radiation area to obtain additional ultrasonic data which is not practically decipherable and would require a proportional increase in radiation 4

exposure to the available examination personnel. Therefore, these personnel would not be available for the performance of ultrasonic examinations of as many lines or at as many sites.

Necessarily, this would force the industry to reduce the sampling rate of examinations because of the inavailability of trained personnel. The Attachment lA Page 2 of 9

reduction of sample size would have a detrimental effect on the monitoring of plant integrity through inservice inspection and would eliminate the non-mandatory examinations presently

- performed by the utilities in the interest of promptly examining known or suspected problem areas.

4. A typical example of the impracticality of the 20% level recording / evaluation practice involved the examination of the 4" Recirculation Bypass lines in a nuclear power plant. The job required both 45-degree and 60-degree angle-beam examinations on one or both side of 20 pipe welds having a total of 450 inches of weld examination length. To demonstrate the impact of the 20%

recording criteria to the utility, a small sample of a randomly selected weld was examined. Because of radiation levels, the demonstration was limited to one hour. In that hour, 15 separate indications were recorded with the 60-degree examination in 5/8-inch of weld length while 10 indications were recorded with the 45-degree examination in 1-7/8 inches of weld length. Only maximum amplitude positions were recorded and most indications of 20% DAC and greater were recorded. It is recognized that this was a very small sample , but it is believed to be typical of 4" bypass line welds. The three-man crew successfully completed the examinations recording at the 50% level within the one-day of examination time available on the unit.

Evaluation time would have been increased proportionately with dubious conclusions due to the sheer volume of data. The welds were judged to be f ree of cracks based on the 50% DAC recording and 100%

evaluation criteria and several months of successful operation without leaking Attachment lA Page 3 of 9 P8035/05 3 i

9 confir. sed that these examinations, like those performed at several other sites, were effective.

B. Evaluation at 100% and greater provides

- equivalent safety _ _

l. Equivalent safety, comparable to code

• requirements, is assured by the recording / evaluation criteria developed, refined, and qualified by SwRI through many years of research and experience.

This criteria is embodied in current SwRI practice, which requires that:

(a) All indications 50% of DAC or greater shall be recorded.

(b) All indications 100% of DAC or greater shall be investigated by a Level II or Level III operator to the extent necessary to determine the shape, identity, and location of the reflectors.

(c) Any indication 20% of DAC or greater and suspected by the operator to be other than geometric in nature, including all 20% or greater indications originating in the base metal, shall be recorded and investigated by a Leval II or Level III examiner to the extent necessary to determine the shape, identity, and location.of the reflector.

• It must be noted that the 100% evaluation criteria was (and is) the Code requirement for utilities commited to the 1971 Edition of Section XI (S71 Addenda). The inconsistency arose when the 1974 Edition of Section XI incorporated Section V by reference. In the. Summer of 1976 Edition (IWA-2232) the ASME has reconfirmed its previous position by clearly requiring evaluation of only indications of 100% DAC or greater.

Attachment lA Page 4 of 9 P8035/05 4

(d) Any indications investigated and

' found to be other than geometric in nature shall be reported to the owner for evaluation and disposition.

SwRI's long-standing requirement to record 50% DAC information reflects the necessity to record a sublevel of data below that point at which we feel a concern. The prime reason for recording this information is to allow for the known variation in reproducibility of i test data. We have shown data reproducibility to be a factor caused by many thing including operator experience, training, procedure, equipment

variations, environmental encumberances,

' test piece conditions, calibration standards, etc. These facators are i routine and will continue to occur during the application of examinations of this nature on piping. This practice is belived to be more conservative than the

-intent of any editior. of the Code and to provide greater safety.at less cost in time, dollars, and radiation exposure to personnel than simply requiring the recording / evaluation of all 20% DAC data.

2. The adequacy of this practice is supported by the follosing:

(a) Except f or a very limited number of applications of the 20% evaluation level criteria of Paragraph IX-3470 of the 1971 issue of Section III, the 100% reference level evaluation ,

criteria of Paragraph IS-213.5 of the Summer 1971 Addenda to Section XI was in effect until ' the adoption in late 1976 of the 1974 Edition of Section XI. The 100% recording criteria was endorsed by the Section V Subcommittee for Nondestructive Examination in a Attachment lA Page 5 of 9 P8035/05 5

- ,---, - - v---.

.v Code Inquiry of 1973, and appeared in Paragraph T-544 of the 1974 Edition of Section v. There is no question of the overall success of the inservice examination program

- during.these many years, and the I

100% evaluation criteria was reconfirmed by ASME in' Paragraph IWA-2232 of the Summer 1976 Addenda to the Section XI code. .

(b) As a result of the different failure mode of austenitic piping (noted in Paragraph (d) below) SwRI had developed modified approaches in procedure to maintain assurance of maximum crack detection sensitivity. Search unit size, frequency and beam angle, as well as procedure, are optimized to take advantage of the known parameters of the type of f ailure to be detected and investigated in different situations.

(c) While it has been demonstrated that j- significantly deep through-wall stress-corrosion cracking may give l

only a low amplitude response, it a

has been demonstrated by SwRI on

multiple plants that the 100%

evaluation criteria, augmented by 4 operator investigation at the 20%

level, can be applied with satisfactory results:

i (1) No component or pipe examined by SwRI has experienced leaking by way of a stress-corrosion crack between the periodic a ;aminations.

(2) At least 48 piping cracks have been found and repaired

)~ in the early stages of propagation.

Attachment lA Page 6 of 9 P8035/05 6

+ - - - - - _, , _ _ _ _ _ _ ., __,_. . . _ , - _ . _ . , ,I

(d) Much experience has shown that the typical mode of f ailure in stainless steel piping is not in the weld metal, per se, but is

" stress-corrosion cracking" in the adjacent heat-affected zone (HAZ) and base metal. A trained UT operator can distinguish the dif ference between the usual weld-metal geometric indications and the somewhat similar indictions due to stress-corrosion cracking by noting their location in the base metal of HAZ. This is true even when their amplitude is in the 20%

to 50% range and even though indications in this range originating in the weld metal cannot be identified.

(e) A prime example of the adequacy of the total SwRI examination technique is th a t Recirculation Bypass lines have been ultrasonically examined in accordance with RO Bulletin 74-10 in six nuclear power plants.

Thirteen cracks were found in four plants and the findings were confirmed by other methods, including excavation, in all cases. As noted above, no component or pipe examined by SwRI has experienced leaking by way of stress-corrosion cracking between periodic examinations.

Summary and Conclusions III. For the reasons enumerated above, SwRI recommends to its clients that, in the interests ot maintaising maximum nuclear power plant integrity and safety at minimum cost in time and personnel radiation exposure, and efforc to institute a blanket 20% DAC recording / evaluation criteria be i

4 resisted. Instead, SwRI recommends a commitment to the SwRI recording / evaluation practice which was set out in Paragraph B.1 above and is reinterated below:

(a) All indications 50% of DAC or greater shall be recorded.

(b) All indications 100% of DAC or greater shall be investigated by a Level II or l

Level III operator to the extent necessary to determine the shape, identity, and location of the reflectors.

(c) Any indication 20% of DAC or greater suspected by the operator to be other than geometric in nature, including all 20% or greater indications originating in the base metal, shall be recorded and investigated by a Level II or. Level III examiner to the extent necessary to determine the shape, identity, and location of the reflector.

(d) Any 171.ications investigated and found to be o'ber than geometric in nature shall be reported to the owner for evaluation and disposition.

Reactor Vessel Inlet Nozzle to Shell Welds Vo.ametric examination will not be performed when the Core Barrel is in' place due to inaccessibility. The examinations will be performed when the core barrel is removed during the inspection interval. These welds are identified.as 27.5-RCN-1210, 27.5-RCN-1220, 27.5-RCN-1230, and 27.5-RCN-1240 in the examination l plan.

As indicated in PSE&G Sketch No. 8-15-77 attached, the Core Barrel covers the weld area when it is in place.

Since all weld examinations are performed from the inside surface using a mechanized inspection device, these welds are inaccessible at this time. Examina-tions cannot be performed from the outside surface due to the area being covered by insulation on the shell of the weld and the configuration of the weld joint on the nozzle side'of the weld. The insulation on the shell portion of the- reactor vessel is not designed for removability and to remove-it would. require the cutting away of the insulation support rings f rom the vessel.

T Since the Core Barrel is scheduled to be removed at or near the end of the inspection interval, and ASME Code Case N-73 (1647) allows these examinations to be deferred toithe end of each inspection interval, i t is PSE&G's position that the intent of the Code is being complied with.

As indicated in PSE&G Sketch No. 8-16-77 attached, the Core Barrel covers the reactor vessel 'ase metal when it is in place. Since all weld examin. ions are per-formed from the inside surface using a: automated inspection device, these welds are inaccessible at this time. Examination cannot be performed from the out-sidesurface due to the area being covered by insulation which would require the. cutting away of the insulation support rings to remove.

Since the Core Barrel is scheduled to be removed at or near the end of the inspection interval, and ASME Code Case N-73 (1647) allows these examinations to be deferred to the end of each inspection interval, it is PSE&G's position that the intent of the Code is being complied with.
