response letter of March 4, 1980.

The licensee was unable to produce documentation which described the scope, content, or specific results of these reviews.

Subsequently, the re riews were determined to be incomplete or unperformed for the 125 VDC electrical systems (80-20-09).

Corrective Action Taken 1.

In addition to the reviews of the 120 VAC Vital busses and the associated revisions to the BVPS Operating Manual, Chapter 38, Abnormal Procedures, which were completed and referenced in the inspection report (80-20-09) additional reviews -were made related to DC busses to cover the full scope of the IE Bulletin 79-27 and a supplemental response to the Bulletin wcs provided on October 21, 1980.

The review performed consisted of a failure mode on loss of DC power analysis for each load on the load list for each DC bus.

The loads were analyzed on a system-by-system basis to determine the overall effect on the plant and to form the basie. for developing Abnormal Procedures to cope with the loss of the DC bus as required by the Bulletin.

No design modifications were identified as being required.

The OSC reviewed and approved the Abnormal Procedures developed from this investigation.

Records have been placed in the files of the Licensing and Compliance Section documenting the reviews performed (80-20-09).
