l,'! 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 boundary 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-cable 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 have 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 tqe position of PSE&G that the relief will not compromise the integrity of safety related components. RFB:az LP4 la

ATTACHMENT 1 ITEMS 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 when the pumps are disassembled for maintenance. All bolts in Category B-G-2 will be examined visually during the inspection interval. If visual examination reveals indications of distress, the bolts will be removed for surface and/or volumetric examination.
2. Ultrasonic indications will be recorded at 50% of 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.

Justification for departure from a 20% reference level evaluation criterion for all UT examinations is explained in detail in Attachment lA, prepared by Southwest Research Institute as agents for PSE&G.

3. Ultrasonic examination of ferritic piping will be per-formed in accordance with Article 5 of Section 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.
4. Inaccessibililty for examination was identified during the Preservice Inspection and has been described in the Remarks column of Tables l and 2 of the Salem No. 2 Preoperational Baseline Examination Report. Those 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 lB for convenient reference.

Comments in these tables are necessarily brief. P8023/05 01 Page 1 of 2

ATTACHMENT 1 (CONT'D) Information in greater detail has been provided in the way of additional comments, also included as part of Attachment lC. Consideration of alternate methods are discussed and in some cases sketches are attached for greater clarity.

5. Welds having limi~ed ultrasonic examinations are treated in the same manner and are included in the tables and comments mentioned above. No distinction is made between items having no accessibility and limited
            .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.

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 presents 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%). Discussion II. Southwest Research Institute (SwRI) presents the fol~owing considerations on these two closely related questions, taking them in order: A. The impracticalit~ recording/evaluation at the 20% reference level.

1. The welded joints in nuclear piping frequently contain code-allowable wall thickness differences (12-1/2% of thickness) as well as allowable weld 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 20% 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 also produce indications greater than 20%

Attachment lA Page 1 of 9 P8035/05 1

  • .t 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 the large number of equally high amplitude geometric indications from the adjacent root area which, in effect, masked the test data to preclude identifying these cracks. Reducing the recording level to 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 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 P8035/05 2

  • J 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 iridications 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 free of cracks based on the SO% DAC recording and 100% evaluation criteria and several months of successful operation without leaking Attachment lA Page 3 of 9 P8035/05 3

confirmed that these examinations, like those performed at several other sites, were effective. B. Evaluation at 100% and greater provides equivalent safety.

1. 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 reflect0rs. (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 Level 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 r~producibility of 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 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 edition 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 following:

(a) Except for 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

  • J 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 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 failure to be detected and investigated in different situations. (c) While it has been demonstrated that significantly deep through-wall stress-corrosion cracking may give only a low amplitude response, it has been demonstrated by SwRI on multiple plants that the 100% evaluation criteria, augmented by operator investigation at the 20% level, can be applied with satisfactory results: (1) No component or pipe examined by SwRI has experienced leaking by way of a stress-corrosion crack between the periodic examinations. (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

.. ( J (d) Much experience has shown that the typical mode of failure 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 difference 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 that 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 reco~~ends to its clients that, in the interests of maintaining maximum nuclear power plant integrity and safety at ~inimum cost in time and personnel radiation exposure, and effort to institute a blanket 20% DAC recording/evaluation criteria be Attachment lA Page 7 of 9 P8035/05 7

I - resisted. Instead, SwRI recommends a commitment to the SwRI recording/evaluation practice which was set out in Paragraph B.l 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 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 indications invest~gated and found to be other than geometric in nature shall be reported to the owner for evaluation and disposition. Attachment lA Page 8 of 9 P8035/05 8

DETAILED EXPLANATION OF EXCEPTIONS TO THE ASME BOILER AND PRESSURE VESSEL CODE SECTION XI FOR THE SALEM UNIT NO. 2 INSERVICE INSPECTION PROGRAM Item Bl.2  Category B-B Closure Head Peel Segment-To-Disc Circumferential Weld Volumetric examination will not be performed on this weld due to inaccessibility. A visual examination for leaks will be performed during pressure tests required by Section XI. This weld is identified as 2-RPVCH-6446 B in the examination plan.

As indicated in PSE&G Sketch No. 8-9-77 attached, this weld is located within the area covered by the Control Rod Drive Penetrations. This location prevents access to the weld for any type of volumetric or surface examination from either the inside or outside surface of the closure head. To gain access would required re-moving and re-installing numerous Control Rod Drive penetration tubes. Bottom Head Peel Segment-To-Disc Circumferential Weld Volumetric examination will not be performed on this weld due to inaccessibility. A visual examination for leaks will be performed during pressure tests required by Section XI. This weld is identified as 2-RPV-3443 in the examination plan. As indicated in PSE&G Sketch No. 8-9-77 attached, this weld is located within the area covered by the instrumentation tube penetrations. This location prevents access to the weld for any type of volumetric or surface examination from either the inside or out-side surface of the bottom head. To gain access would require removing and re-installing numerous instrumen-tation tubes. P802304 01 Page 1 of 5

ATTACHMENT lC (CONT'D) Item Bl.4 Category B-D Reactor Vessel Inlet Nozzle to Shell Welds Volumetric 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 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 surf ace 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 from the vessel. 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. Reactor Vessel Outlet Nozzle to Shell Welds Volumetric examination will be performed with the Core Barrel in place except for the examination of the Reactor Vessel base metal due to inaccessibility. The base metal will be examined when the Core Barrel is removed during the inspection interval. These welds are identified as 29-RCN-1210, 29-RCN-1220, 29-RCN-1230, and 29-RCN-1240 in the examination plan. P802304 02 Page 2 of 5

ATTACHMENT lC (CONT'D} As indicated in PSE&G Sketch No. 8-16-77 attached, the Core Barrel covers the reactor vessel base metal when it is in place. Since all weld examinations are per-formed from the inside surface using an 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. Item Bl.14 Category B-I-1 Reactor Vessel Cladding Visual examination will not be performed on the Reactor' Vessel Shell Cladding when the Core Barrel is in place due to inaccessibility. The patches of cladding to be examined are identified as 2-RPV-Patch-l, 2-RPV-Patch-2, 2-RPV-Patch-3, 2-RPV-Patch-4, 2-RPV-Patch-5, and2-RPV-Patch-6 in the examination plan. Since this examination can only be performed from the inside surface of the reactor vessel shell, the exami-nation can only be performed when the Core Barrel is removed. The Core Barrel is scheduled to be removed at or near the end of the inspection interval. Item B4.5 Category B-J Reactor Coolant Loop Piping Longitudinal Welds Volumetric examinations will not be performed on the longitudinal welds in the Reactor Coolant piping elbows. Surface examinations will be performed as well as a visual examination for leaks required by Section P802304 03 Page 3 of 5

ATTACHMENT lC (CONT'D) XI. These welds are identified in the examination plan as the LU-1, LU-0, LD-1, and LD-0 welds on lines 31-RC-1240,31-RC-1230, 31-RC-1220, 31-RC-1210, 29-RC-1240, 29-RC-1230, 29-RC-1220, and 29-RC-~210. The Reactor Coolant loop elbows are made of cast stain-less steel which cannot be penetrated by ultrasonic examination techniques. Also, acceptable radiographs cannot be obtained by present techniques due to fogging of the film caused by long exposure time coupled with background radiation from the reactor coolant piping. Radiography will be considered as new techniques are developed that would make it possible to examine these welds in the future. Reactor Coolant Loop Piping Circumferential Welds Volumetric examination on eight reactor coolant loop piping ~~lds will be limited during inservice inspection due to restricted access. These welds are identified as 31-RC-1210-5 and 6, 31-RC-1220-5 and 6, 31-RC-1230-5 and 6, and 31-RC-1240-5 and 6 in the examination plan. Due to anti-whip restraints that were installed after the preservice examination was completed, portions of these circumferential welds are inaccessible for inservice examination. Item B5.6 Category B-L-1 Reactor Coolant Pump Casing Welds A visual examination for leaks will be performed. The Reactor Coolant Pump casings are made of cast stainless steel which cannot be penetrated by ultra-sonic examination techniques. Also, acceptable radio-graphs cannot be obtained due to fogging of the film P802304 04 Page 4 of 5
