Subject:

Virgil C. Sum =er Nuclear Station, Unit 1 Reportable Significant Deficiency Bergen-Patterson Mechanical Shock Arrestor Assemblies Nuclear Engineering File: 3.1051

Dear Mr. O'Reilly:

On March 4,1980, Mr. Jack Skolds of NRC Region II was notified orally of a reportable significant deficiency.

Bergen-Patterson Pipe Support Corporation (B-P) has previously identified these potential problems with mechanical shock arrestor assemblies to the NRC.

Icunediately upon our notification f rom Southwest Fabricating and Welding Company, with confirming lettera from B-P and upon receipt of the IEC, Supplement A, inspections were begun by SCE6G. Initially it did not appear that the design of any of the shock arrestors would be affected by the deficiency as reported by B-P. Continuing investigation has now identified one shock arrestor of the B-P design which could possibly cause a substantial safety hazard defined by 10CFR21. We are reporting this as a significant deficiency under 10CFR50.55(e). Detailed information is found in Attachment I.

Since corrective action has been etermined and is in progress, SCESC considers this the final report on this item. If any questions arise, please let us know.

eryl uly yours,
