50-280/79-63 AND 50-281/79-83 NRC Comment :

As required by 10 CFR 50 Appendix B, Criterion V which states in part that "Activities affecting quality shall be prescribed in documented instructions, procedures, or drawings, of a. type appropriate to the circumstances and shall be accomplished in accordance with these instructions, procedures, or drawings" and as implemented by the Nuclear Power Station Quality Assurance Manual (NPSQAM), Section 2 (QA Program), "Design Changes must be processed and evaluated using the procedures of NPSQAM, Section 3.

Contrary to the above, on September 21, 1979, a design change was made to the starting circuit of a Safety Class I emergency diesel fire pump engine without a design change request being submitted and evaluated (MR 5-0908210831).

This is an infraction.

Response

• The non-compliance is correct as stated.

1.) Corrective steps which have been taken and results achieved:

The starting circuit of the Emergency Diesel Fire Pump was*proven operable by performing PT-24. 1. A Design Change has been completed on the replacement starting contactors. The Design Change concluded the _

replacement of the #118848 magnetic switch with the Cummins recommended

1. 199573 D.C. relay results in an improved starting circuit.

2.) Corrective steps which will be taken to avoid further non-compliance:

Futnre changes to safety-related systems will be accomplished by design change in accordance with NPSQAM, Section 3, 3.) Date when full compliance will be achieved:

Full compliance has been achieved.
