Docket Nos.:

Columbus, Ohio 43215

SUBJECT:

ANTICIPATED TRANSIENTS WITHOUT SCRAM -

DONALD C.

COOK NUCLEAR PLANT, UNITS 1

AND 2 The Nuclear Regulatory Commission (NRC) staff has completed its review of the Westinghouse Owners'roup (WOG) Topical Report WCAP-10858 "AMSAC Generic Design Package" submitted in response to 10 CFR 50.62 "Requirements for Re-duction of Risk from Anticipated Transient Without Scram (ATWS) Events for Light-Water-Cooled Nuclear Power Plants."

Guidance for meeting the require-ments of 10 CFR 50.62 was provided in the preamble to that rule and was further provided to all licensees in Generic Letter 85-06 "guality Assurance Guidance for ATWS Equipment That is Not Safety Related."

The results of the staff's review of the generic design for the ATWS mitiga-tion system actuation circuitry (AMSAC) are contained in the attached Safety Evaluation (SE).

The staff has concluded that the generic design is acceptable;

however, many plant specific details needed in order to ensure conformance with the rule are not addressed by the WOG generic design.

These details needed by the NRC to complete the review are defined in the SE.

We request that you review the SE and provide, within 30 days of receipt of this letter, your schedules for addressing the plant specific design features discussed in Appendix A of the SE, and for implementation following the staff's approval of your plant specific design.

This request for information is covered under OMB clearance number 3150-0011 which expires September 30, 1986.

If you have any questions, please contact me at (301) 492-7363.

Sincerely, Si09i~0OOS SiO9ae PDR ADOCK 05'0003' P,.
