REPORTABLE DEFICIENCY AND CORRECTIVE ACTION WPPSS NUCLEAR PROJECT NO. 2 LARGE BORE ASME PIPING WITH LESS THAN RE UIRED MINIMUM WALL WASHINGTON PUBLIC POWER SUPPLY SYSTEM DOCKET NO. 50-397

~ LICENSE NO. CPPR-93 Descri tion of Deficienc:

Large diameter piping has tqen found to have less than the ASME Code required minimum wall 'thickness. This underwall condition was caused by over-grinding while preparing weld profiles for ASME Section XI In Service Inspection (ISI) .

Safet Si nificance:

a If the underwall condition were. to be left uncorrected, it could result in the violation of piping pressure bounderies. This could adversely affect personnel safety and the safe operation of the plant.

Corrective Action:

Project Engineering Directive, PED-215-M-3337, has been issued to our mechanical contractor, which controls grinding, assures that wall thickness measurements are performed on all blended areas and directs the mechanical contractor to revise appropriate procedures accordingly.

A separate contract'issued to Lambert, McGill and Thomas Co. (C14402) directs them to measure the remaining wall thickness .of all previously blended ISI areas and to report the results to WNP2 Engineering. This data is being evaluated to determine the scope of the problem. Subsequent to this evaluation, individual areas will be repaired, as required, to conform to the ASME Code.

Completion of the physical re-work is estimated to be September, 1981.

This date is contingent upon the resolution of the current labor negotiations and the lifting of the Stop Work Orders effecting guality Class 1 work at WNP-2.
