Docket 50-267 Mr. O. R. Lee, Vice President Electric Production Public Service Company of Colorado P.O. Box 840 Denver, Colorado 80201

Dear Mr. Lee:

As a result of the problems encountered during the testing of the emergency diesel generator sets (EDGs) on December 18, 1984, the NRC has reevaluated the Fort St. Vrain (FSV) emergency electrical systems. The results of our review are contained in the enclosed Safety Evaluation (SE). We have concluded that, even with the potential EDG single failure and independence problems identified in the SE, FSV can be operated safely for an interim period while corrective measures are being pursued.

Your commitment to provide an evaluation of the above problems, within 90 days of your June 14,1985 (P-85208) submittal, will be confirmed in the listing of various commitments that will be issued with the authorization to restart FSV.

In addition to the safety questions addressed in the enclosed SE, the question of plant operation in possible nonconformance with the established licensing basis (FSAR) must be examined from a regulatory compliance viewpoint. We have discussed this matter with members of your staff and are awaiting additional information.

If your have any questions on this matter, please contact the NRC Project Manager, P. Wagner, at (817)860-8127.

Since the reporting requirement relates solely to FSV, OMB clearance is not required under P.L.96-511.

Sincerely.

Oddrk!SWOdBY E. H. JCh000" E. H. Johnson, Chief Reactor Projects Branch
