[C Infrac: ion

.Appandix.3.of-10CFR30, cri:erion V, states, in-par::

'" Activities affecting quality... shall be acconplished in accordance with these instrue: ions, procedures or drawings."

The Limerick PSAR, Appendix D, Quality Assurance Progra=,

Paragraph D.6.4, s'tates, in part, : hat: Bechtel Construe: ion Department... is responsible for construe: ion of the plant to approved engineering specifications, drawings, and procedures..."

Sechtel.Powe$ Corporation Project Special Provision Procedure C-6.1, Revision 2, states in Section 4.4,

" Engineering changes which effect compla:ed work that requires further construction, shall have a new inspection record initiated by construction QC. The new. inspection-record is developed to cover the inspection of the work

~

required to accomplish the engineering change."

Contrary'to the above, as of July 6, 1979, a' Field Design i , .

Change Notice No. 5 to Design Drawing C-292 effected the completed and QC accepted weld joint ~on a pipe restraint,

.({') identified as PR-9. A new inspection' record was not developed f' to cover the inspec: ion of the work required to acco=plish E -' the engineering change. As a result, the. work required'by the engineering change was not accomplished on PR-9.

Resoonse to Infraction A Bechtel Quality Control inspected .PR-9 and the nonconforming conditions were documented-for Engineering disposition.

Project Engineering dispositioned the nonconfor=ing conditions by specifying a rep, air procedure that will meet specification and structural design requriscents.

[-

Subsequently, Quality Control re-inspected all restraints affected by Field Design Change Notice No. 5 to Dws. C-292

and identified similar conditions on pipe rest sin
PR-45.

The same repair procedure as above was specified by ?rojec:

Engineering.

Repair werk'for both pipe restraints will be completed by-November 16, 1979.

Development of corrective action to preclude recurrence is in progress and wil.'. be fully imple=ented by January 1, 1980.

The Li=erick ?SAR, Appendix 3, Quality Assurance Progra=,

Bechtel-Prisary' Containment Specification C2 (Revision 9),

Section 10 .~ 1.14 , applies :o temporary bracke:s among other things, and states that: " Preheat at~ 20 Co F.minimu= shall be applied to-all. carbon steel seams'whose thickness exceeds

~

1-1/4"'regardless of a:bient temperature."

Contrary to the above, as of July 6, 1979,. temporary brackets were welded at several locations on the liner plate, where the place thickness was 1-1/2 inches, and no preheat was applied.

~

Response to Infraction 3 Weld documentation (WR-NC-1 Forms) has been reconstructed fro =

existing Quality Control records of the subject welds to the g(~ containmen: liner place. The documentation and control forms *-

\) ,..

(WR-NC-1) have been fastened to the temporary attachments. For

( ;.

.these temporary attachments WR-NC-1 requires a visual examination-i and a~ dye penetrant test of the affected base metal-after the removal of the temporary attachments. This dye penetrant test will' assure that any indications resulting from the lack of preheat

  • will be discovered and dispositioned. ,

As a matter ~of-interest, Weld Request (WR) Forms and Wald Filler Metal Authori:ation (WR-NC-2). Forms existed for the subject vsids and show that the welding was performed by qualified welders.

Additionally, a letter of instruction was issued to require l

L-Quality Control Inspection / Records to be issued. prior to performing temporary attachment welding to the containment liner.- This will I ' insure compliance with specified requirements such as preheat L

prior to welding.
