Mr. Boyce Grier, Director 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

Corrective Action The corrective action taken at the site as well as the corrective action taken to prevent reoccurrence remains as stated in our 30-day written report (our letter to you SNRC-300 dated June 22, 1978).

Date of Full Compliance All required inspections and rework have been completed. The programs which have been implemented to prevent reoccurrence of this deficiency have been successful. During a recent NRC field inspection (Inspection No. 50-322/79-21), the inspector examined the records relevant to this issue and found them satisfactory.
