These proposed revisions are in accordance with the NRC guidance provided by Generic letter 91-04, " Changes in Technical I Specification Surveillance Intervals to Accommodate a 24-Month Fuel Cycle."

Proposed Setpoint Revisions Required by the Results of The DBNPS Instrument Drift Study The Allowable Values for the following Technical Specifications are proposed for revision and the associated Trip Setpoir.t are proposed for deletion: TS 3.3.2.2, Steam and Feedwater Rupture Control System Instrumentation (SFRCS) Table 3.3-12, Functional Unit 2 (Steam Generator Level - Low). The proposed Allowable Value is to be defined as applicable to the Channel Functional Test only by application of an existing footnote in Table 3.3-12.

The Limiting Condition for Operation and Action a for TS 3.3.2.2, SFRCS Instrumentation, are proposed for revision to reflect the proposed changes to the Trip Setpoint and Allowable Values.

These proposed revisions are based on NUREG-1430, Revision 1,

" Standard Technical Specifications, Babcock and Wilcox Plants,"

dated April 1995.

Dockat Numbar 50-346 License Number NPF-3 Serial Number 2428 Page 5 Proposed Revisions to Technical Specification 2.2, Limiting Safety System Settings The Allowable Value for TS Table 2.2-1, Reactor Protection System Instrumentation Trip Setpoints, Functional Unit 2, High Flux is proposed for revision from 104.94% of Rated Thermal Power (RTP) with four pumps operating to 105.1% of RTP with four pumps operating.

The Trip Setpoints, Trip Setpoint column and column heading for Technical Specification Table 2.2-1, Reactor Protection Sy3 tem Instrumentation Trip Setpo3nts, are proposed for deletion and the associated Allowable values are proposed to be defined as applicable to the Channel Functional Test only by application of an existing footnote "*" in Table 2.2-1.

Technical Specification 2.2, Limiting Safety System settings, is proposed for revision to reflect the proposed revisions to TS Table 2.2-1.

These proposed revisions are based on the results of the revised Framatome " Reactor Protection System String Error Calculations" (document 32-1172392-02, dated July 26, 1996) and the "DBNPS Unit 1 RPS Setpoint Allowable Values Calculation" (document 32-1257719-02, dated September 25, 1996) and are consistent with NUREG-1430, Revision 1, " Standard Technical Specifications, Babcock and Wilcox Plants," dated April 1995.

Proposed Administrative Revisions Technical Specification Table 4.3-10, Post-Accident Monitoring Instrumentation Surveillance Requirements, Instrument 6, Containment Vessel Post-Accident Radiation is proposed for revision to reflect the revision to 24 month surveillance intervals for the High Rang 9 Radiation Monitors, and to reflect that the Containment Wide Range Noble Gas monitors will remain on a 18 month surveillance frequency.

Technical Specification Bases 2.2.1, Reactor Protection System Instrumentation Setpoints, and TS Bases 3/4.3.1 and 3/4.3.2, Reactor Protection System and Safety System Instrumentation, are proposed for revision to reflect the proposed revisions to TS 2.2, Limiting Safety System Settings, and TS 3/4.3.2, Safety System Instrumentation, Safety Features Actuation System Instrumentation, and Steam and Feedwater Rupture Control System Instrumentation.

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

This license amendment application is one of several applications which l will be submitted in support of the 24 month fuel cycle conversion.

l These applications are being submitted to the NRC as a Cost Beneficial l Licensing Action. As will be demonstrated in each license amendment

! application, the proposed changes will not adversely impact safety. The i proposed changes will provide an estimated cost savings of $24 million over the DBNPS's remaining life.

Docket Number 50-346 Licensa Number NPF-3 j Serial Number 2428 i Page 6 i License Amendment Request (LAR) 95-0027 (DBNPS letter Serial Number 2405) proposes a revision to TS Definition Table 1.2 redefining Notation "R" l from "At least once per 18 months" to "At least once per 24 months" and defining a new Notation "E" as "At least once per 18 months."

)

l There are several revisions proposed to Surveillance Requirement intervals by this LAR (95-0024) in which the interval is defined by the j "R" notation and it is proposed to apply the new definition of the "R" '

notation discussed in LAR 95-0027. )

All 18 month Survoillance Requirement intesials currently defined by the "R" notation that are to remain at 18 months will be designated by the new "E" notation. All Surveillance Requirement revisions from "R" to "E" notation are proposed under LAR 95-0027 with one exception which is 1 discussed in this LAR.

l License Amendment Request 95-0018 (DBNPS letter Serial Number 2342 dated I I

August 7, 1996) proposes a new TS defined term, REFUELING INTERVAL, which is defined as "A period of time 5 730 days."

There are several revisions proposed to Surveillance Requirement intervals by this LAR (95-0024) in which the interval is proposed to be defined by this new defined term, REFUELING INTERVAL. Other instrumentation Surveillance Requirement intervals proposed to be revised to REFUELING INTERVAL are proposed in LAR 95-027.

License Amendment Request 96-014 which addresses the instrument drift study for TS 3.3.2.1 and TS 4.3.2.1.1 (Safety Features Actuation System Instrumentation), and TS 4.5.2.d (Decay Heat Valve Interlock Channel Functional Test) is scheduled to be submitted to the NRC by May 1997.

Toledo Edison requests that amendments for LAR 95-0018, 95-0027, 96-0014, I

and this amendment application, LAR 95-0024, be issued together by the NRC by December 5, 1997.
