Subject:

Proposed Modification to the Davis-Besse Nuclear Power Station Unit 1 Facility Operating License NPF-3 Appendix A, Technical Specifications for Conversion to a 24 Month Fuel Cycle Ladies and Gentlemen:

Enclosed is an application for an amendment to the Davis-Besse Nucledr Power Station (DBNPS), Unit Number 1, Operating License Number NPF-3, Appendix A, Technical Specifications. The proposed changes involve:

Technical Specification (TS) 3/4.5.2, ECCS Subsystems - T avg > 280'F; TS 3/4.5.3, ECCS Subsystems - T avg < 280*F; TS 3/4.7.1.2, Auxiliary Feedwater System; TS 3/4.7.1.7 Motor Driven Feedwater Pump System; TS 3/4.7.3.1, Component Cooling Water System; and TS 3/4.7.4.1, Service Water System.

The proposed changes would modify the presently specified 18 month surveillance frequencies in TS Surveillance Requirement (SR) 4.5.2.d.2.a, SR 4.5.2.e, SR 4.5.2.g.2, SR 4.5.3, SR 4.7.1.2.1.c, SR 4.7.1.7.d, SR 4.7.3.1.b, and SR 4.7.4.1.b to new specified frequencies of once each Refueling Interval. These changes are in accordance with the NRC guidance provided by Generic Letter 91-04, " Changes in Technical Specification Surveillance Intervals to Accommodate a 24-Month Fuel Cycle," and will support conversion of the DBNPS from an 18 month to a 24 month fuel cycle.

The LL PS is commencing longer fuel cycles during the current cycle 11.

This license amendment application is one of several applications which will be submitted in support of the 24 month fuel cycle conversion. These applications are being submitted to the NRC as a Cost Beneficial Licensing Action. As will be demonstrated in each license amendment application, the proposed changes will not adversely impact safety. The proposed changes will provide an estimated cost savings of $24 million over the DBNPS's I I
