SUMMARY

OF INDICATIONS I As a result of the examinations performed by Southwest Research Institute, General Electric Company, Lambert-MacGill-Thomas Inc., and the Philadelphia Electric Company during the February 14, 1983 to October 24, 1983 Inservice Inspection of Peach Bottom Atomic Power Station, Unit Three, the following indications were observed:

I. Indications Observed by Southwest Research Institute:

I The manual UT examination of Class I and Class TT com-ponents revealed nucarous insignificant and geometric indi-cations. Three reportable indications were observed on Class I Main Steam examination areas. Minor slag inclusions were noted on hanger lug weld numbers 1-A-5HL1 and 1-A-5HL2. The indication on lug weld 1-A-SHL1 was recorded during the Pre-operational Baseline Examination. An engineering analysis I performed by the General Ricctric Company concluded t he st rem.

In the "us is" condition Lu be sigullleanL1y beiow ANS1 153 I . I Code allowable. Hanger lug weld 1-A-5HL2 contained a similar I inclusion but of lesser amplitude. No repairs were required.

In the third area, weld 1-C-6, a laminar indication was noted.

This indication was previously recorded and sized during the preoperational baseline examination and has shown no signifi-cant change since then. No repair was required.

II. Indications Observed by General Electric Company The UT and RT examination of Class I Main Recirculation and Residual Heat Removal system pipe welds revealed 15 welds I with reportable indications. Main Recirculation Riser welds 2-AHF-2, 2-AHG-2, 2-AHH-2, 2-AHJ-2, 2-AHK-2, 2-BHA-2, 2-BHB-2, 2-BHC-2, 2-BHD-2, 2-BHE-2, and Residual Heat Removal Shutdown Cooling Suction welds 10-0-5, 10-0-6, 10-0-7, 10-0-10, and 10-0-15 contained intergranular stress corrosion cracking

! indications. Subsequent to temporary repair by weld clad l overlay, all repairs were satisfactorily re-examined.

l l5 Also, original weld defects were observed on Main l

Recirculation Riser welds 2-AHil-1 and 2-AHK-2. These defects g were detected during radiographic examination (MINAC) and g dispositioned as acceptable under the existing fracture mechanics.

i III. Indications Observed by Lambert-MacGill-Thomas Inc.

1 No reportable indications were revealed.

1 I .

I I

Page 2 IV. Indications Observed by Philadelphia Electric Company The visual examination of Class I components revealed a re-portable indication in one area. An improper retaining pin was I noted on High Pressure Coolant Injection pipe support 3-23DBN-H64.

Following replacement, a satisfactory inspection was performed.

I As a result of the vluual examinations performed on Clar.. Il components, reportable indications were observed in twelve Re-sidual Heat Removal support components. The setting in spring hangers 3-10GB-H70, 3-10GB-H56, 3-10GB-H57, 3-10011-1187, 3-10Gli-ill31, and 3-101115-1118 were found to be out of range. Subsequent to being reset, all b.'ngers were satisfactorily re-examined, lient hanger rods were noted on supports 3-10GB-H132, 3-10GB-H133 and -

3-10GB-S46. Following replaceaent, all hangers were found to be acceptable. Linear indications were noted on the concrete RHR "A" Pump base (Pump-A-SC). Subsequent to repair by ;; routing, no reportable indications were noted. The visual and mat;netic particle examination of hangers 3-101115-1137 and 'l-10llit-il'1H revealed linear indications on the saddle-to-pipe attachment welds. Aller repair by welding, no reportable indications were observed.

E1 MINATION AREA IDENTIFICATICN SYSTEM

!ach component to be examined (veld, vessel, 11gsmenes, etc.) is identified by a unique coded character. For vessel components, che identifying characcer la essencially an abbreviation of the component name sequencially numbered where more chan one of each cype of component exists. Designacions for components lccated on the closure head begin with the lectors "CH", while che essainder of the vessel component designations, vich the excepcion of those for the nozzle-co-shell welds, begin with the letters "RPV"; vessel nozzle-to-shell weld desig-nacions begin wich che 1stcar "N*. The remainder of each component designation crnsists of letter / number combinacions identifying the nacure of the individual etaponents. For example, CH-MA identifies closure head (CH) meridional (M) vald A, RPV-MA identifies vessel lower head (RPV) meridional (M) weld A RPV-C5 Identifies vessel (RPV) circumferencial (C) weld 5, and N3A identifies Sain Secam (N3) nozzle-to-shell weld.

Fer piping components, che designation system is, of necessity, more cosplex dua to che number of components involved and of ten consists of a number of parcs.

(1) The first chaeaccer set in each code consists of a numbee which desig-naces the piping system under consideracion. Salow is a cable showing l the .mmber or letters with their respective systems:

J7 - Jet Pump Instrumancacion Piping System (2) The second character set includes alphabetic codes which indicace , loop, function, and/or status. 3ecause of the variety in some syscecs, examples are given below:

A , 8 , C , D-- A , 3, C, and D Loops, respectively ASS, ASC, AS D , AS E-- A Loop , Saf ety and Re L Lef 11 sors 3, C,D, and E respectively, in Syscas 1 A-1[

i 1, 2, 3, 4, 3--Circumferencial veld cumber in direccion of flow 4LU-Longitudinal veld upstream f rom circumferencial veld 4 6LD-Longitudinal weld downstream from circumferencial veld 6 33C--3 ranch Connection (4-in. nominal and smalle r) downs t ream f rom I circasferencial veld 3 1RL-Res c raint Lug downstream from circumf erencial veld 7 5HL--P.ange r Lug downstream f rom circu=f e rencial veld 5 3PS-Pipe Support downstream from circumf ereccial veld 3 (4) If there is a fourth character sec, it describes the successive -elds of the third character see:

Lectors ref er to sequencial branch connecciona. Numbers ref er to ;unger lugs, pipe supports, and restraine lugs. I.f there are :ultiple lugs at a particular position on a pipe, they are numbered clockwise with respect I to direccion of flow. If chere are successive multiple lugs at a partic-ular posicion on a pipe, a fif th character see will be numberad clockwise with respect to direccion of flow.

I I . ..

I I

(5) For branch conneccions larger than 4 inches, the follouing three parc notation is used:

(X) / (Y)

(X) Coacains the system, loop, and weld number of the main run of pipe.

I / Indicates the branch connection is larger than 4 inches.

(T) Contains the branch line identifier.

An example for such a branch connection is:

1-A-7/ASE System 1 (Main Steam System), Loop A, Branch Connection larger than 4 inches, Safety and Rollef Riser E.

I (6) Representative examples of the veld numbers and their explanation include:

1-ASE-2 System 1 (Main Steam System), Safety and Relief Riser E, circuaterential veld 2.

2-AS-7LU System 2 (Main Recirculation System) A Loop Suction Side of Pump, longitudinal veld upstream from circumferential veld 7.

I 2-AS-6HL-1 through 4 System 2 (Main Recirculation System)

A Loop Suction Side of Pump, Hanger Lug downstress from circumf erential veld 6, 4 lugs, ausbered clockwise with respect to direction of flow.

I 2-SM-3HL-2-1 System 2 (Main Recirculation System) 3 Loop Manifold, Hanger Lug downstreas f rom Hanger Lug 2-3M-3HL-1, first lug clockwise with respect to direction of flov.

Agsin in this column and i= mediately under the veld designation, there are further descriptions of each respective weld. These descriptions, such as

" pipe-to-albow" and reducer-to-tee," are listed in the direction of flow.

EXAMINATION AREA IDENTIFICATION SYSTIM Each component (weld, vessel, etc.) to be examined is identified by a unique I ' coded character.For vessel components, the identifying character is essen-tially an abbreviation of the component name, sequentially numbered where more than one of each type of component exists. For piping such as the Fuel Pool I Coolant-Loop A System (FPCA), Shutdown Cooling Suction--Pump A (SCSA), Contain-ment Spray-In Loop A (CSIA), etc., the designated system consists of several parts: -

(1) The first character set is 10, representing the Residual Heat Removal system.

I (2) The second character set consists of a unique line identification. The first digit is a "2," signifying Class 2. The line designation follows, including the nominal pipe size (for example, 2FPCA16 and 2CSI.tt24, respectively).

(3) The third character set is usually a L- or 2-digit number identifying a specific circumferential weld. Icess such as pipe supports, pipe restraints, etc., are identified by adding initials to the number of the circumferential weld directly upst. ream. For example, -3PS is a pipe support downstream from circumferencial weld No. 5. If there are successive components between circumferencial welds, a L-digit number is assigned.

For example, two pipe supports following circumferential veld No. 5 would be designated as -5PSL and -3PS2 in the direction of flow.

(4) Representative examples are as follows (see Appendix 3, Figure 3-2):

10-2HS6-6 Sixth circumferential weld in sequence on the Residual Reat Removal (10)--Clas s 2 Head Speay 6-in.

nominal pipe si:e.

10-2HS6-6PS Pipe support directly downstream from weld No. 6 referred to in (a). If two pipe supports exist between veld Nos. 6 and 7, their veld numbers would be -6 PSI and -6PS2, respectively.

Again in this column and i= mediately under the weld designation, there are further descriptions of each respective veld. These descriptiocs, such as I " pipe-to-elbow" and " reducer-to-tee," are listed in the direction of flow.
