SUMMARY

OF EXAMINATIONS

'O During the period from July 15, 1985 to March 12, 1986 an Inservice Inspection (ISI) was performed at the Peach Bottom Atomic Power Station, Unit No.

3.

This Inservice Inspection completed the first ten-year interval.

z)

In addition to examinations set forth by ASME Section XI, other examinations were performed to meet the i

requirements of NUREG-0313, Generic Letter 84-11, IE Bulletin 80-13, and NUREG-0619.

1 The examinations completed were performed by qualified personnel of Southwest Research Institute, General Electric Company, and Philadelphia Electric Company.

The following is a summary of the examinations performed employing:

PT-Dye Penetrant, MT-Magnetic Particle, UT-Ultrasonics, and VT-q)

SUMMARY

OF INDICATIONS

'O The examinations performed by Southwest Research Institute and General Electric Company during the July 15, 1985 to March 12, 1986 Inservice Inspection of Peach Bottom Atomic Power Station, Unit No. 3, identified forty welds that appear to contain Intergranular Stress O

Corrosion cracking (IGSCC).

These welds were evaluated for repair or operate "As IS" in accordance with Generic

" Letter 84-11 and the ASME Code Section XI as well as the proposed acceptance criteria for flux welds.

I.

Indications Observed by Southwest Reasearch Institute (SWRI):

O The manual ultrasonic (UT) examinations of Class I and II components revealed numerous insignificant and geometric indications as well the following five Class I pipe welds that appear to contain IGSCC.

The welds that were repaired are identified by an asterisk (*).

Disposition of Five Welds Weld No.'s 2-AD-14, 10-IA-5, and 10-IB-3 were shown not to exceed the allowable flaw size within the 18 month operation cycle and will be operated "As Is".

O Weld No.'s 10-0-1A and 10-0-1B were shown to exceed the allowable flaw size within the 18 month operation cycle.

A full structural weld overlay was selected to provide, as a minimum, a one-cycle repair for these welds.

The repairs'were designed to restore the safety margin to

a factor of 3 as required by ASME Code Section XI.

All repaired welds subsequently received a satisfactory ultrasonic examination which included examination of the weld overlay material, the interface between the overlay and base material, and the outer 25% of the base material.

As a result of the cracking found by SWRI and GECO.,

the examination program was expanded to include all 1

accessible Main Recirculation and Residual Heat Removal

.)

(Stainless Steel) welds that are required to be volumetrically examined by the 1974 Edition of Section XI i

I thru 1975 Addenda with the exception of three 22" Dia.

Recirc manifold welds.

Since our program was increased based on system / pipe diameter, and no cracks were found on Recirculation /22" Dia. piping welds, the three subject g

welds were not required to be examined.

III.

Indications Observed by Philadelphia Electric

()

Company (PECo. ) :

A crack-like indication was visually observed on the south-side of the A & C Core Spray supply junction box, 240 degrees Azimuth, during an In-Vessel examination.

A crack-like indication was also observed on the north-side 3

of the junction box subsequent to cleaning the area and a bubble test.

The junction box was repaired by means of a welded bracket and a baseline examination was satisfactorily performed.

In addition, a welded bracket was installed on the 120 degree Azimuth junction box for preventative maintenance purposes.

EXAMINATION AREA IDENTIFICATION SYSTEM Each component to be examined (weld, vessel, ligaments, etc.) is identi-fied by a unique coded character. For vessel components, the identifying character is essentially an abbreviation of the component name sequen-

C) tially numbered where more than one of each type of component exists.

Designations for components located on the closure head begin with the letters "CH", while the remainder of the vessel component designations, with the exception of those for the nossle-to-shell welds, begin with the letters 9EPV"; vessel nossle-to-shell weld designations begin with the letter "N".

The remainder of each component designation consists of letter / number combinations identifying the nature of the individual com-g For example, CH-MA identifies cloeure head (CH) meridional (M) ponents.

weld A. RPV-MA identifies vessel lower head (RPV) seridional (M) weld A.

RPV-C5 identifies vessel (RPV) circumferential (C) weld 5, and N3h identi-fies Main Steam (N3) nozzle-to-shell weld.

The first character set in each code consists of a number which designates the piping system under consideration. Below is a table showing.the number or letters with their respective systems:

The second character set includes alphabetic codes which indicate loop, function, and/or status. Because of the variety in some sys-tems, examples are given below:

The third character set represents the veld number respeetive to the i

direction of flow or direction of the longitudinal weld from the i

circumferential welds:

If there is a fourth character set, it describes the successive welds of the third character set:

I Letters refer to sequential branch connections. Numbers refer to hanger lugs, pipe supports, and restraint lugs. If there are mul-g, tiple lugs at a particular position on a pipe, they are numbered Figure A-iv A-2

.O

O clockwise with respect to direction of flow. If there are succes-sive multiple lugs at a particular position on a pipe, a fif th (3

character set will be numbered clockwise with respect to direction of flow.

(5)

For branch connections larger than 4 inches, the following three-part notation is used:

()

(I) / (Y)

(I)

Contains the systan, loop, and weld number of the main run of pipe.

/

Indicates the branch connection is larger than 4 inches.

()

(Y)

Contains the branch line identifier.

An example for such a branch connection is:

Connection larger than 4 inches, Safety and Relief Riser E.

O EXAMINATION AREA IDENTIFICATION SYSTEM l

C)

Each component (weld, vessel, etc.) to be examined is identified by a unique 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), Con-tainment Spray-In Loop A (CSIA), etc., the designated system consists of

!C)

• eV8f81 parts:

(1)

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

1 (2)

Ihe second character set consists of a unique lina identification. The i

lg) first digit is a "2," signifying Class 2.

The line designation follows, including the nominal pipe size (for example, 2FPCA16) and 2CSIA124 j

respectively).

l (3)

The third character set is usually a 1-or 2-digit number identifying a specific circumferentici weld. Items such as pipe supports, pipe restraints, etc., are identified by adding initials to the number of the

. C) circumferential weld directly upstream.

For example, -5PS is a pipe sup-port downstream from circumferential weld No. 5.

If there are successive components between circumferential velds, a 1-digit number is assigned.

For example, two pipe supports following circumferential weld No. 5 would be designated as -5PS1 and -5PS2 in the cirection of flow.

(4)

Represantative examples are as follows (see Appendix B, Figure B-2):

10-2HS6-6 Sixth circumferential weld in sequence on the Rasidual Heat Removal (10)--Class 2 Head Spray 6-in. nominal pipe size.

l C) 1 10-2HS6-6PS Pipe support directly downstress from weld No. 6 referred i

to in (a).

If two pipe supports exist between veld Nos. 6 i

and 7, their weld numbers would be -6PS1 and -6PS2, respectively.

C)

Again in this column and immediately under the weld designation, there are further descriptions of each respective weld.

These descriptions, such as

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