CENTERIOR ENERGY Donald C. Shetton 300 Madison Avenue Vee Pre 9 dent Nuclear Toledo, OH A36520001 l Davis Besse (419)249 2300 Docket Number 50-346 License Number NPP-3 Setial Number 2081 November 13, 1992 lini ted States Nuclear Regulatory Commission Document Control Desk Washington, D. C. 20555 Subj ec t : License Amendment Request t a Inctease the Reactor Protection System (RPS) and Anticipatory Reactor Trip System (ARTS)

Channel Functional Test Surveillance Interval and Channel Bypass Allowed-Out-of-Service Time Gentlemen:

Enclosed is an application for an amendment to the Davis-Besse Nuclear Povet Station, Unit 1 (DBNPS), Operating License Number NPF-3, Appendix A., Technical Specifications (TS). The proposed changes involve TS 3/4.3.1, " Reactor Protection System (RPS) Instrumentation," and TS 3/4.3.2.3, " Anticipatory Reactor Trip System Instrumentation."

The main purpose of the proposed changes is to implement the NRC-approved Babcock and Vilcox (B&V) Topical Report, BAV-10167, l " Justification for Increasing the Reactor Trip System On-Line Test Intervals," and supplements, for the DBNPS. The proposed changes revise TS 3/4.3.1, " Reactor Protection System Instrumentation," t.nd 3/4.3.2.3, " Anticipatory Reactor Trip System Instrumentation," tot

1. Increase the channel functional test surveillance test interval for most RPS and ARTS instrument channels.

2. Allow plant operation to continue indefinitely with one RPS l instrument channel placed in bypass, t

' 3- ^dd "" "*' " St^t***"' t P"'*it c "ti""*d Per^ti " I r 'a 1N04G hours with two RPS channels inoperable.

4. Remove channel functional test surveillance requirements for source and intermediate range neutron flux instrumentation.

5. Decrease the channel calibration surveillance test interval for the High Flux / Number of Reactor Coolant Pumps On trip from once every eighteen months to quarterly.

6. Correct a typographical error in the numbering of page 3/4 3-30c.

Since these Technical Specification changes vould decrease the tikelihood of a spurious channel trip causing a reactor trip with one

O strument channel inoperable, and reduce manhours expended on performing channel functional tests, Toledo Edison requests that the Nhc appt ove these changes by May 30, 1993.

Il you have any questions regarding this amendment request, please l contact Mr. Robert V. Schrauder, Manager - Nuclear Licensing, at (419) 249-2366.
