, Technical Specification Change-Request No. 60A -

The licensee requests that the attached revised pages replace pages 3-37, 4-7, 4-39, 4-40, and 4-46 of the existing Technical Specifications, Appendix A.

Reasons for Amended Change Request The original request was to comply.vith the NRC's June 3, 1977 memo requesting a comparison of our design to the Star'f Position. This amendment to TSCR 60 is being submitted to reflect the changes in design resulting from the new criteria in the May 2,1979 and August 8,1979 letter: f rom the NhC.

Safety Analysis Justifying Change The Nuclear Regulatory Commission requires a second level of voltage protection for the onsite power system be provided in order to pre ent a sustained degradation of the offsite power system's voltage from causing the failure of redundant safety-related electrical equipment.

These Technical' Specifications assure that the undervoltage relays adequately protect the safety related electrical equipment from loss of capability as a result of sustained degraded voltage from the offsite electrical grid system.

The equipment remains operable on offsite power during normal and degraded grid conditions and transfers.to the onsite source with minimal time delay upon loss of offsite power.

The setpoints for the undervoltage relays and timers have been selected to prevent cpurious transfers to the onsite source during normal system fluctuations or.

short time transient conditions.

A detailed analysis has been conducted and submitted under TDR 114 Rev. 1.

The added test requicements assure the functional operability of the loss of voltage relays and demonstrate block loading on loss of offsite power and upon tripping and reclosing the diesel generator breaker.

Implementation in order to provid2 the necessary procedures and training, an implementation period of 90 days following the issuance of this amendment is requested.

Licensee Amendment Fee (10 CFR 170.22)

Because this is a modification to a previously submitted change, no fee is required.
