".";;7'.;7l.~n;l:' TXX-3222 Mr. W. C. Seidle, Chief Reactor Construction & Engineering Support Branch U. S. Nuclear Regulatory Commission Office of Inspection & Er.forcement 611 Ryan Plaza Dr., Suite 1000 Docket Nos. 50-445 ,

Arlington, Texas 76012 50-446 COMANCHE PEAK STEAM ELECTRIC STATION DIESEL GENERATOR PIPE SUPPORTS FILE N0: 10110

Dear Mr. Seidle:

In accordance with the requirements of 10 CFR 50.55(e), this letter provides the status of the manufacturing deficiency we reported verbally to your Mr. W. C. Crossman on September 26, 1980, relative to the cc;nponent supports associated with the auxiliary piping systems for the CPSES Unit 1 and Unit 2 Diesel Generators.

Specifications for this equipment imposed the requirements of ASPE III which in turn imposed Subsection NF through Subsection ND, Paragraph 3676.9. The supplier (Delaval) manufactured the supports in accordance with their standard shop procedures without acknowledging the requirements of Subsection NF. This deficiency is currently being evaluated by Engineer-ing with the objective of formulating appropriate corrective action. We plan to file our formal report on this matter on or before January 16, 1981.

If we can provide any additional information, please advise.

Very truly yours, fW6b-,wh
