Subject:

License Amendment Application to Revise MSIV Tech Spec Closure Time Gentlemen:

Enclosed is an application for an Amendment to Facility Operating License No. NPF-3 for the Davis-Bessa Nuclear Power Station, Unit No. 1.

The enclosed application requests that the Davis-Besse Nuclear Power j Station, Unit No. 1 Operating License, Appendix A, Technical Specifica-tions be revised to reflect the changes attached. The proposed changes ]

involve Section 3/4.3.2, Table 3.3-5 Safety Features System Response Times; Section 3/4.3.2, Table 3.3-13, Steam and Feedwater Rupture Control System Response Times; Section 3/4.6.3, Table 3.6-2, Containment Isolation Valves; and Section 3/4.7.1, Specification 4.7.1.5, Main Steam Line Isolation Valves.

l The proposed changes are being submitted to make the Main Steam Isolation i Valve (MSIV) closure time requirements consistent throughout the Technica* i Specifications under the assumptions made in analyses contained in the Updated Safety Analysis Report ('USAR) . The changes also eliminate Tech-nical Specification requirements where they are not needed.to satisfy the j assumptions made in the USAR, while still ensuring complete compliance with I the requirements of 10CFR50, Appendix A: General Design Criteria for Nuclear Power Plants. The elimination of these unnecessary requirements from the j Technical Specifications will facilitate future plant modifications for-improving plant reliability through the. removal of unnecessary redundant  !

automatic functions from components. This submittal satisfies the' commit-  ;

ment Toledo Edison made in a letter dated December 22, 1986 (Serial l No. 1-698) to clarify the MSIV response times listed throughout the Technical Specifications.
