VIRGINIA ELECTRIC AND POWER COMPANY SURRY POWER STATION UNITS 1 AND 2 RESPONSE TO NRC BULLETIN No. 88-10 Serial No.

License Nos.

88-788B Rev 4 50-280 50-281 DPR-32 DPR-37 As requested by NRC Compliance Bulletin No. 88-10, Nonconforming Molded-Case Circuit Breakers, a summary of the total number, manufacturer, model number, and to the extent possible, the procurement chain, has been identified for those molded-case circuit breakers (MCCBs) in our station stores which were purchased before August 1, 1988 and which could not be traced to a circuit breaker manufacturer (CBM).

This summary is provided in Attachment 1.

We are proceeding with the removal of these non-traceable molded-case circuit breakers from our station stores to preclude use in safety-related systems.

As delineated in the February 17, 1989 NRC letter from Mr. F. J. Miraglia to Mr. W.

H. Rasin of NUMARC regarding clarification of NRC Bulletin 88-10, we have opted to proceed directly with the information collection for the molded-case circuit breakers installed in safety-related systems between August 1, 1983 and August 1, 1988 in lieu of testing. However, due to the resource requirements to support the outages at Surry Power Station, we are still in the process of collecting this information. It is our intention to replace any non-traceable molded-case circuit

  • breakers installed in our safety-related systems.

stored spares for future use in safety-related applications. To accomplish this, in the future we will only purchase circuit breakers for use in safety-related systems directly from an approved circuit breaker manufacturer or from an approved distributor that can certify direct traceability to a circuit breaker manufacturer. To provide an additional level of assurance, we will verify this traceability by audit or by other appropriate means.

Prior to restart, we will provide an updated summary of our non-traceable molded case circuit breakers and a schedule for the replacement of the non-traceable installed circuit breakers.

We anticipate establishing traceability for several molded-case circuit breakers currently identified as non-traceable at that time.

These completion dates identified in this letter have been discussed with Mr. B. C.

Buckley of your staff. The information contained herein is true and accurate to the best of my knowledge. Should you have any questions concerning this response please contact us.
