Office of Inspection and Enforcemer.t, Region I l U.S. Nuclear Regulatory Commissior 631 Park Avenue King of Prussia, PA 19401 Long Island Lighting Company Shoreham Nuclear Power Station - Unit 1 Docket No. 50-322

Dear Mr. Grier:

On May 22, 1978, in accordance with 10CFR50. 55 (e) , we reported to Region I a deficiency in a Class 1 pipe weld. This letter serves

-

as our final written report on this deficiency.

Description of Deficiency During an NRC field inspection (Inspection No. 50-322/78-06) a deficiency was noted in a Category I pipe weld. The completed weld had been post weld inspected and accepted however did not meet the weld profile requirements for ISI examination which violates specification SH1-056.

The Mechanical Contractor's Quality Assurance Division reviewed

' the matter and noted the following additional nonconforming conditions:

1. The OD surface of the base metal was ground below the pipe surface in violation of specification SH1-056.
2. An ultrasonic examination was performed to assure that required minimum wall (1.044 inches) had not been violated. /f The actual wall thickness (.950 inches) N<

'

as measured by UT was in violation of l

minimum wall thickness criteria.

The fact that minimum wall was violated after final post weld

,

inspection had been completed constituted a significant breakdown
