Docket Nos. STN-50-528/529/530 Letter dated September 18, 1980 from E.

E.

Van Brunt, Jr. to Dr. H.

R. Denton

Dear Dr. Denton:

The responses of Bechtel Power Corporation to the outstanding open items of the PVNGS Class IE DC Power System Review were submitted to you by the referenced letter.

These responses have been reviewed by the DC System Review Board and were determined by the Board to sufficiently address all outstanding concerns.

As you know, the NRC Branch Chief, Power Systems Branch, participated in the review board meeting and we have kept him advised of the resolution

=.

of all open items.

In keeping with our prior discussions respecting the institution of this type of review, we consider it is appropriate to establish whether or not the DC system description and analysis is satis-factory to the NRC staff, or more specifically, whether the NRC staff has sufficient information and understanding to write the appropriate section of the Palo Verde Safety Evaluation Report.

If your staff has any questions which were not dealt with satisfactorily by the Review Board, we believe such questions should be raised promptly so that such subjects can be closed out completely.

Respectfully submitted, ARIZONA PUBLIC SERVICE CO EEVBJr/JPS/av cc:
