Subject:

License Amendment Application to Revise Instrumentation Technical Specifications and Emergency Core Cooling System Technical Specifications for Conversion to a 24 Mon u Fuel Cycle j (License Amendmene Request No. 96-0014) ]

I Ladies and Gentlemen

• i l

Enclosed is an application for an amendment to the Davis-Besse Nuclear Power Station (DBNPS), Unit Number 1, Operating License Number NPF-3, Appendix A, Technical Specifications. The proposed changes involve Technical Specification (TS) 3/4.3.2.1, Safety Features Actuation System Instrumentation, TS 3/4.5.2, Emergency Core Cooling Systems - ECCS Subsystems - Tavg 2.280*F, and associated Bases.

The proposed changes would modify presently specified 18 month surveillance frequencies in certain TS Surveillance Requirements contained in the above-mentioned TS Sections to new specified frequencies of once each Refueling Interval, or once each 24 months. These changes are in accordance with the NRC guidance provided by Generic Letter 91-04,

" Changes in Technical Specification Surveillance Intervalo to Accommodate a 24-Month Fuel Cycle," and will support conversion of the DBNPS from an 18 month to a 24 month fuel /cle. i The term " Refueling Interval" is defined by TS Definition 1.42 as "a period of time s 730 days." Frequency notation "R", which is presently defined by TS Table 1.2 as a frequency of "At least once per 18 months,"

is being proposed by a separate license amendment application (LAR 95-0027; DBNPS Serial Number 2405 dated December 11, 1996) to be redefined as a frequency of "At least once per 24 months." The frequency notations defined by TS Table 1.2 are utilized in various tables in the Instrumentation Technical Specifications.

Docket Numbsr 50-346

- Licznsa Numbar NPF-3 Serial Number 2441 Page 2 This license amendment application also proposes changes to setpoints, as required by the results of the DBNPS Instrument Drift Study and based on NUREG-1430, Revision 1, " Standard Technical Specifications, Babcock and Wilcox Plants," dated April 1995.

The DBNPS is commencing longer fuel cycles during the current Cycle 11.

This license amendment application is one of several applications which have been 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 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 remaining life.

This license amendment application includes a proposed change to Surveillance Requirement (SR) 4.5.2.d. Several additional license amendment applications submitted to the NRC, including License Amendment Requests (LAR) 95-0019, 95-0022, and 95-0027, also affect SR 4.5.2.d. In addition, as noted above, this license amendment application uses terminology defined in LAR 95-0027. Therefore, Toledo Edison requests that amendments for LAR 95-0019, 95-0022, 95-0024, 95-0027, and this amendment application, LAR 96-0014, be issued together by the NRC by December 5, 1997.

Should you have any questions or require additional information, please contact James L. Freels, Manager - Regulatory Affairs, at (419) 321-8466.
