Docket No. 50-346 79t,gg License No. NPF-3 R case P. CaxSE Serial No. 953 vc. p,.s.o.n N4tv June 2, 1983 a m a m aai Director of Nuclear Reactor Regulation Attention: Mr. John F. Stolz Operating Reactor Branch No. 4 Division of Operating Reactors United States Nuclear Regulatory Commission Washington, D. C. 20555 Gentlemen:

This letter is to transmit a revision to the Inservice Inspection Pump and Valve Program for the Davis-Besse Nuclear Power Station Unit No. 1, which was submitted by letter on May 15, 1980 (Serial No. 616). Please find attached five (5) copics of the revised pages of the Inservice Inspection Pump and Valve Program. The changes made in this revisioa reflect the results of the telephone conversation reviews between The Toledo Edison Company and the United States Nuclear Regulatory Commission Region III held on May 25 and 26, 1983.

As agreed to during the telephone conversations Toledo Edison is sub-mitting specific Relief Requests which needed revision. See Enclosure One (1) for a synopsis of the changes being made to the Program, Enclosure Two (2) for copies of the Relief' Requests that were changed or added, and Enclosure Three (3) for copies of the specific changes to the Pump and Valve Test Program.

Any additions that become necessary, due to modifications and changes to this program during the course of the remainder of the 120 month interval, which do not meet the code testing requirements, will be implemented as needed. A fully documented notification to the NRC will be placed on the docket subsequent to the implementation of approved changes.

Very truly yours, RPC:RFP:JDE:nif encl.

RELIEF REQUEST NUMBER 15 Components: MU 66A, B, C, D; MU 59A, B, C, D; MU 38 Function: Reactor coolant pump seal water isolation valve Class: 2 Test Requirements: Quarterly stroking per IWV-3412 Basis for Relief Request - Cycling valve during normal operation would interrupt flow to reactor coolant pump seals and is not permitted by plant operating procedure.

Alternative Testing - Valve will be full stroke tested during those entries into cold-shutdown when normal cold shutdown proceeds to reactor coolant pump shutdown.

Valve design precludes partial stroke f.esting during normal operation. Valves will be tested at refueling per Technical Specification during Appendix J. Type C Test.

o RELIEF REQUEST NUMBER 21 Components: CC1411A, CC1411B, CC1407A, CC1407B

-Function: Component cooling water isolation valve Class: 2.

Test Requirements: Quarterly stroking per IWV-3412 Basis for Relief Request - Cycling valve during normal operation requires shutting off cooling water to the reactor coolant pumps which would cause extensive damage to the pumps.

Alternative Testing - Valve will be full stroke tested during those entries into cold shutdown when normal cold shutdown proceeds to reactor coolant pump shutdown.

Valve design precludes partial stroke testing during normal operation.

RELIEF REQUEST NUMBER 28 Components: HP43 & HP50; HP49 & HPS1; HP56 & HP58; HP57 & HP59 Function: -High pressure injection normally closed stop check valve and swing check valve forming ASME Class 2 to Claas 1 pressure boundary.

Class: 1 Test Requirements: Quarterly reverse flow stroking per IWV-3412 Basis for Relief Rcquest - Reverse flow cycling during normal operation, cold shutdown, and refueling is precluded by system design for individual check valves.

Upstream of these valves are motor operated normally closed valves which are designed and analyzed as seismic class I. These motor operated valves HP-2A, B, C, & D are stroked and timed at cold shutdown. The system normal operating pressure is continually monitored in the Control Room by a high pressure alarm set at 3/5 psig.

Alternative Testing - As an interim condition, no alternative testing is proposed until resolution of alternatives is complete.

RELIEF REQUEST NUMBER-29 i

Components: SW83, SW85, SW91, SW93, SW99, SW101, SW107, SW109, SW115, SW117, SW370, SW372, SW380, SW382, SW329, SW82, SW335, SW43, SW44, SW57

' Function: Service water check valves.

Class: 3 f

Test Requirements: Quarterly reverse flow stroking per IWV-3412 Basis for Relief Request - Present system design configuration does not permit isolation required for testing.

Alternative Testing - No further alternative testing is proposed at this time.

System modifications are being considered to permit testing. The modifications

- are presently being planned for implementation during the 1984 Refueling Outage.
