INSERVICE INSPECTION PROGRAM FIRST INTERVAL.

Specification NE 42, Rev. I LGS 1 ISI Program Page 1-i of 81 O s u u u ^itv oi ni x isio s i The primary purpose of this revision is to incorporate the impact of the reconciliation of examinations

. completed under the original First Interval ISI Program (Spec P 500), with the overall first interval ASME Section XI requirements of the updated program.

A majority of the changes have occurred in the ISI Program Tables. The changes reflect adjustment made to the selection of components for examination for the purpose of identifying only those examinations requirJ for the remainder of the interval. (Rev. O reflected a complete ten year program without consideration of examinations completed during the first three refueling outages).

Additional elements of the revision include:

1. Addition of Appendix D " Component Selection Criteria" This appendix provides guidance to both station and NESD personnel for performing selection of components for examination, and monitoring progress or adherence to program commitments.

2, Addition of aportion of the RWCU System to the AUG 1 Inspection Program,solumetric examination scope.

Tids addition was required by the USNRC Safety Evaluation of the I.GS-1 Generic I etter 88 01 respome and initiated by EWK A 0002908.

3. Deletion of Relief Request RR il.

This deletion was precipitated by USNRC rejevion of the corresponding relief request for LGS-2 ISI Program. Its content will be re es-Juated following results of applicable examinations attempted during IRO4.

4. Reddon 'o content of Relief Request RR 12

~This relief request was revised due to updating of Regulatory Guide 1.147, which adopted 2 of the Code Cases previouslylisted as this Relief Requestc Additionally new Code Cases were added to the Relief Request.-

5. Resision to content of Relier Request RR-13 Deleted portions of this relief request addressing Class 2 inservice and functional t.: sting due to clarification of Code intent received from recent ASME Section XI Code inquiry. Added P & ID references where applicable.

6. Revision to PECo position on estent of required examinations for Class 1 & 2 integral attachment welds- (Cmle Category ll K-1 nod C-C)

7. Correction of miscellanmus typographical criors and adjustment to format or presentation of various program elements.

Due to the nonic forging configuration, portions of the Code required examination volume cannot be completely examined. The curvature of the blend radius of the nonle forging is such that ultrasonic scanning of the wehl is interrupted due to low of contact of the uhrasonic search unit This limitation affects both transvere and parallel scanning of the Code required examination volume.

In support of AI.All A,28 of the 34 nonic to venel welds are examined utilizing remote automatic ultrasonic tehniques.

1,GS i has several ItPV noule to safe end welds which incorporate alloy 182 as either weld material, weld buttering or both. These welds are detailed in Table 117-1. ,

IV.  !!EAMINNI' ION l'ItOGit AM The minimum examination requirements for the subject welds are in accordance with .

NitC Nt1RPG 0313, AliG.I (iteferences 11, C), and ASMii Section Xi. Ilrictly, this means that. the subject welds fall within the scope of NitC Nt!!tEG 0313 and the A11G-1 program and as such are subject to the personnel, procedure, and examination frequency, etc.

requirements of these mandatory documents. Also, the subject welds are within the scope of O ASMI!Section XI and are subject to the requirements of IIxamination Category Il-F, -

In addition to the above, Gli Sil No,455 recommends further actions be taken to ensure early detection of insipient cracking. These are summarized below:

, 1) 45 degree and 60 degree refracted longitudinal waves shall be used in 1JT detection and sizing in both alloy 182 weld material and nonle base material.

L a) / Exams should be performed at gain levels such that "lD rolli signals are approximately l0"4 I Sil.

I_

b). Suspect iedications should be further investigated using a 45 degree shear us en for c6 .cnce of cracking in the nonle base material.

All snubbers installed on the reactor coolant system and all other safety related systems are subject to the requirements .'f this augmented inspection program. Snubbers installed on nonsafety related systems are ahn within the scope of this prapam and may be excluded only.if their failure or failure of the system on which they are installed would have no adverse effect on any safety related system.

P.xamination and testing requirements of this aupnented inspection program apply to the -

snubber assembly which includes the snubber body and attachments out to and inchiding the hind pins and their retainers (l'igure 11 131). Snubber support components beyond this defined space are outside of the scope of this augmented inspection program.

This augmented inspection program ( Al'G 16) defines the specific eumination recommendations of General Illectrk Company (Gl:) Nuclear ServFes Infortnation I etter (Sil ) No. 462, a: applicable to I GS 1. This Sil addresses the intergranular stiess conosion cracking (IGSCC) of the shroud support access hole covers and the Gli recommer ded actions reganling susceptibility / routine examination.

I1. lUit'lillIJNCliS A. Gli Sil No. 461, Si,tou,1 Support Access hole Cover Cracks, Supplement I, li ebruary 22,1989.

O 111. Gl!Niifs/_.1 There are two (2) access holes in the shroud support plate which are utilized for access to the lower plenum during construction and are subsequently closed by welded access hole covers. As reported in Sil. No,462, cracking in the access hole cover plate attachment wehl has been detected in a llWit/4 The cracking occurred in the heat affected tone of the creviced alloy 600 access hole cover plate and is attributed to crevice aceclerated IGSCC.

While the i GS 1 design eliminated the creviced Alloy 600 plate configuration on both access hole covers, the existing design retained a crevice in the 3161, stair'ess steel cover plate in one (1) access hole cover. Alihough 3101,in itself is considered a IGSCC resistant material, the crevic ed wehl configuration adversely affects this design ( overall susceptibility to IGSCC.

As such, augmented examination is recommended. ,

Theerfore, augmented visual (V l-1) examination of the 180' azimuth shroud access hole cover, as recommended by Gli, should be perfonned during the plant's temh year of operation.

Note that both access hole ccvers have been included for routine visual (VT-3) examination in accordance with the ISI program for Code lixamination Category II.N-1; satisfaction of this AUG 16 program involves upgrading the visual examination for the IRO' cover from VT-3 to VT 1 during the Gnal refueling outage of the first inservice inspection interval.

Reykw of plant water chemistry and/or the inddence of IGSCC in other RPV internal components may necessitate o revised frequency of this examination. .

Included in the scope of this document are the selection bases for all 1.GS nonexempt Class I,2, and 3 components arid their supports subject to the nondestructive and visual examir,ation requirements of ASN1F Section XI (the Code) Specifically excluded from

_h discussion in this document are components subject to (T-2 visuat examination during system pressure testing.

Additionally, this document specifies the selection eriteria applicable to each Augmented Inspection Program included in this Specification.

LIMERICK GENERATING STATION . UN!T I Insenkt Inspection Program df-~ First Tem Year Inspection latenal Code Edition Upgrade,1980/%181 To 1986 EXAMINATION RECiLfilliTION REPORT

!. INTRODUtilON Gilbert /Corrimonwealth, loc. has been tasked by Ph:ladelphia Electric Company with upgrading the Limerick Generating Station, Unit 1, First Ten Year Interval, insenice f rapection Program from the ASME Section XI 1980 Edition with Addenda thru Winter 1981 (1980/W81), to the 1986 Edition.

Since thh is a midterm program upgrade, the establishment of an effective cutoli point for the closing of the 1980/W81 Program and the start of the 1986 Program was required. PECO has determined that the 1980/W81 Program would be implemented through the third refueling outage, which is the first outage in the second inspection period. Therefore, implementation of the 1986 Program (Spe.ification NE 42) would commence with the completion of the third refueling outage.

IL PURPOSE D The inspection requirements of the 1986 Edition of ASME Section XI difier from that of the 1980/W81

\ Edition establisa/ Addenda, ed and therefore subt.equently appliedaas'retenciliation"-f the completed credit towards the completion portion of the 1986 of the 1980/W81 Program. Program mu 111, DISCUSSlDN i

l When the 1986 ISI Program was initially prepared, selection of components for examination was made in accordance with the 1986 Code selection gtudance for the entire first interval, thus pro 5iding a base ISI Program.

This ' Reconciliation Report

• was then generated to establish the extent of completion credit to be applied from the 1980/W81 Program to the 1966 Program. This document is prepared and compiled for each applicable Caic Category, and provides the necessary detaih and calculatmns needed to ider.tify the credit j applied to the 1986 Program.

The approach taken for the reconciliation of examinations completed under the 1980/W81 Program is as follows:

A. Each Code Category was reconciled indhidually by calculating the percentage of examinations completed under the 1980/W81 Program relative to the 1980/W81 Code required examination population. ,

1

1. The calculated completion percentages (credits) were limited to the maximum allowable credit percentages as discussed in the 1980/W81 Code (eg. Table IWB.24121), Any examinations m i excess of the maximum allowables were not used towards the credit applied to the 1986 Program.

, Naoucillation Report

2. Deleted components (ie. due to removal during plant modifications) were n(t comidered when calculating the 19u0/W81 Pregram compktion percentages even thongh scme of these consponents may have teen cumined prior to deletion. These deleted components will have little or no impact on the results of the reconciliation.

B. The completioe percentages were then applied to the cumination populations of the 1986 Program to determine the number of cuminations that may be credited as completed. From this, the remaining number of examinations to te scheduled for the balance of the interval,in accordance with the 1986 l'rogram, was determined.

C. %e cuminations identified as a credit towards the 1986 Prograrn were then appropriately identified in the 1986 Program database. -This resulted in changes to the selection of compnents for.

enmination. A revision to the 1986 ISI Program (Specification NE 42) will te tuued to reflect these changes in sclersion of components for cumination resulting from this reconciliation.

IV. CONCLUS10,N Results of the reconciliation have shown that the 1980fW81 Prc5 tram has met or exceeded the requirements of the 1980/W81 ASME Section X1 Code for the first insgection period (first two refueling outages), Additionally, the third refueling outage (first outage of the second perimi) has teen conducted under the 1980/W81 Program, and therefore will contribute towards satisfyir4 the requirements of the second period, which will be completed in accordance with the 1986 Progra n.

Current scheduling of the remaining 14 welds, indicates 2 welds are to be examined during the second period, and 12 welds are to be cumined during the third period. This schedule will result in a 53%

completion by the end of the second period which is within the allowable percentage range for laspecion Program 'B'(minimum 50% and maximum 679). It is recommended that the scheduling be adjusted to examine 5 of the remaining 14 welds during the second period which would provide for a total completion credit of 65%. Tha balance of 9 welds should then be scheduled for the thirJ period.

Examination of item B6.30 is only required when the closurc studs are removed. The 1986 Program also requires 100% examination of Code items B6.180 and B6.200. Examination of Code ite.m B6.190 is required when the connection is disassembled. The requirement to examine items B6.180, B6.190, and B6.200 is the result of a change in the Code which requires examination of boiting on components selected for examination under Category B L-2 instead of B L-1, The completion requirements of Table IWB 24121 do not apply since footnote 5 to Table IWB 2500-1 for examination Category B G 1 allows deferral of the examinations to the end of the inspection interval.

.( permitted, and the remaining 200 examinations are scheduled, no scheduling adjustments are required for these item Numbers.

Since Code item Numbers B5.180 and B6.200 were not required to be examined t.nder the 1980AV81 Program, 200% of the required examinations (1 pump per multi component group) must be performed in accordance with the 1986 Program. The 2 Reactor Rectreulation pumps are the only Class 1 pumps having pressure retaining bolting greater that. 2 inches at LGS 1, and are listed as multi component group number 20.

An adjustment to the s chedule will be necessary to schedule the examination of 1 pump for Items B6.180 and B6.200. Since deferral to the end of the interval is allowed, these examinatmns should be scheduled for the third period.

For Code item Number B7.70, examinations are to be performed on at least one valve within each group of valves that are of the same size, constructional design, manufacturing method, and that perform similar functions in the system, and they are scHeed for examination under Category B.M 2. While all Category B-M 2 valves have been selected for potentir] examination (if disassembled) in the 1986 Program, only one valve from each group of similar valves has been selected for examination under Item Number B7.70. The Inspection Program "B* completion requirements contained in Table IWB-24121 apply to the above item Numbers.

Required to examine = 178 (Plus associated longitudinal welds)

There are a total of 290 longitudinal welds for item Number B9.12 that are associated with the circumferential welds (Items B9.11, and Category B I'). The longitudinal welds are not considered in the calculations for the examination populations, however they are selected and scheduled for examination coincident with the selected circumferential welds.

The total number of non-exempt circumferential trids chssified as Code mandatory (meeting items 1 & 2 above) is 52. This equates to 7.3% of the total non-exempt circumferential butt weld population of 710. Therefore the Code required examination population was established as 25% of the non-exempt circumferential weld population, (ie.178 components).

It should be noted that the 1980/W81 Program indicates that a total of 241 Category B J non exempt circumferential welds were scheduled to be cumined during the first interval. Suice the examination population was intended to be a 25% sample, the examination population of 241 is artificially high.

Three explanations collectively account for the disparity in the population of required examinations g3 (ie.178 required, versus 241 scheduled, which is 33.9% of 710)

(/

1. Selections were made based on 25% of the weld population uithin each system and applicable Code item Number and all fractional percentages were rounded up. (Approximately 4 welds)

2. Welds required to be examined in accordance uith the NUREG4E00 Augmented Program (not required for ASME XI) were included in the total population of Code required cuminations (ie. 241). (Approximately 10 welds)

3. All (100%) of Category B-J wc!ds from the RPV ISI Program document, prepared by G.E.,

were scheduled for examination. These scheduled welds were not considered when the piping database welds were selected to fill out the 25% sample. (Approximately 49 welds)

Inspection program 'B*, as def;ned in ASME Section XI, specifies that a minimum of 16% of the enmination population be completed in the first period and the maximum percentage credited shall not exceed 34%.

F1.10 = 25% of the total population of Class 1 piping supports.

F1.20 = 15% of the total population of Class 2 p3pmg supports.

F1.30 = 10% of the total population of Class 3 pipmg supp:rts.

F1.40 = 100% of the total population of equipment supports.

Note: The actual enmination populations for piping supports are slightly , higher than the required percentages since a minimum of one support of each type m each system was seleded where calcu.ated percentages were greater than reto but less than one.

The examination population for Item F1.40 (coulpment supports) includes the supports of only one component where there are multiple components within a system of simuar design, funcion and service.
