Re: Turkey Point Units 3 and 4 Docket Nos. 50-250 and 50-25l Revision to Inservice Test Pro ram for Purn s and Valves On March 30, l984, Florida Power & Light Company submitted a revision to the Inservice test (IST) Program for Pumps and Valves for Turkey Point Units 3 and 4 (FPL letter No. L-84-84). The NRC Staff is currently reviewing this revision.

A recent RHR pump problem revealed that exercising certain safety injection system valves, when the RCS is pressurized, could result in transient conditions which could exceed the limits of IO CFR 50 Appendix G. This was discussed in a conference call on October l9, l987 between NRC staff and FPL staff personnel.

Accordingly, we have revised the Turkey Point Unit Nos. 3 and 4 lnservice Test Program to provide for testing certain safety injection valves at cold shutdown when the RCS is depressurized and vented and during each refueling outage.

Attached are revised Safety Injection System Relief Request Bases Nos. 3, 4 and

8. The attached pages supersede the same numbered pages included in our March 30, I 984 submittal.

If there should be any questions, please contact us.'incerely,

. O. oo Grou President Nuclear Energy Attachrnent, COW/TCG/gp cc: Dr. J. Nelson Grace, Regional Administrator, Region ll, USNRC Senior Resident Inspector, USNRC, Turkey Point Plant Mr. Herbert C. Rockhold, EG&G Idaho, Inc.

Turkey Point Plant No. 3 6 4 Page 2 of 13 RELIEF REERUEST BASIS SYSTEM: Safety Injection

3. Valve: MOV-~-863A and MOV-*-863B Category: B Class: 2 Function: Provides the flow path to the alternate header to the Reactor Coolant System from the Low Pressure Safety Injection System. Also, provides the flow path to the High Presure Safety Injection System during the recirculation mode.

Test Requirement: IWV-3410 Basis for Relief: The failure of either of these valves in the open position, by testing during plant operation, would result in diverting flow from the reactor core in the event of a safety injection signal.

Alternate Testing: These valves will be tested during cold shut'down, when the RCS is depressurized and vented and during each refueling outage.

4. Valve: MOV-*-872 Category: A Class: 2 Function: Provides the alternate flow path from the Low Pressure Safety Injection System to the Reactor Coolant System.

Test Requirements IWV-3410 Basis for Relief: The failure of this valve in the non-closed position, by testing during plant operation, rende'rs high pressure long term Safety Injection System recirculation unavailable.

Alternate Testing: This valve will be tested during cold shutdown, when the RCS is depressurized and vented and during each refueling outage.

Turkey Pcint Plant No. 3 t 4 Page 4 of 13 RELIEF REEUEST BASIS SYSTEM: Safety Injection

7. Valve: *-876A, *-876C and *-876B Category: C Class: 1 Function: Prevents reverse flow from the Accumulator Safety Injection System and the High Pressure Safety Injection System to the Low Pressure Safety Injection System.

Test Requirement: IWV-3520 Basis for Relief: These valves cannot be tested during operation because the Low Pressure Safety Injection pumps do not develop sufficient discharge head to establish a flow path to the Reactor Coolant Systemo Alternate Testing: These valves will be tested during cold shutdowns.

8. Valve: *-876D and *-876E Category: AC Class: 1 Function: Prevents reverse flow from the Accumulator Safety Injection System and the High Pressure Safety Injection System to the Low Pressure Safety Injection System alternate flow path.

Test Requirements IWV-3520 Basis for Relief: These valves cannot be tested during plant operation because the Low Pressure Safety Injection pumps do not develop sufficientto the discharge head to establish a flow path Reactor Coolant System.

Alternate Testing: These valves will be tested during cold shutdown, when the RCS is depressurized and vented and during each refueling outage.
