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,
