Dear Mr. Keppler:

AMENDED 10CFR50.55(e) REPORT BERGEN-PATERSON PIPE SUPPORT STRUT WITH MECHANICAL SHOCK ARRESTOR CALLAWAY PLANT UNIT 1 Ref: ULNRC-386, 9/10/80

On July 2, 1980 we provided NRC Region III verbal noti-

.fication of a 10CFR50.55(e) report regarding a potential bolt head-pipe clamp interference which could hinder the full function of Bergen-Paterson (B-P) pipe support strut assemblies containing Pacific Scientific mechanical shock arrestors. In the final report transmitted with the referenced letter we indicated that information Bechtel Power Corporation had received from B-P advised that all assemblies for Callaway Unit I were corrected prior to shipnent.

We have now determined that two pipe support strut assemblies delivered to callaway have not been corrected. These items are identified by hanger mark numbers 2-EM01-R030/112 and 2-EM01-C043/112.

Bechtel Power Corporation has analyzed these two supports and has determined that no condition adverse to safety would result if the existing interference were not corrected. ,

These two supports, one installed and one in the warehouse, have been placed on hold anc will be appropriately dispositioned according to existing non-conformance control procedures.

Very truly yours,

.ro nf
