NUCLEAR REGULATORY COMMISSION WASHINGTON, D. C. 20555 ENCLOSURE I SAFETY EVALUATION DOCKET NOS. 50-250/251 TURKEY POINT PLANT UNITS 3
& 4 GENERIC LETTER 83-28 ITEM 4.5.2 REACTOR TRIP SYSTEM RELIABILITY ON-LINE TESTING INTRODUCTION Generic Letter 83-28 was issued by NRC on July 8, 1983, indicating actions to be taken by applicants and licensees based on the generic implications of the Salem ATWS events.
Item 4.5 states a staff position which requires on-line functional testing of the reactor trip system, including independent testing of the diverse trip features of the reactor trip breakers, for all plants.
Item 4.5.2 requires applicants and licensees with plants not currently designed to permit this periodic on-line testing to justify not making modifications to permit such testing.
By letter dated November 8, 1983, the licensee, Florida Power and Light Company, responded to the staff position regarding Item 4.5.2 of Generic Letter 83-28.
Our review of this response finds it to be acceptable.
EVALUATION The licensee states that Turkey Point has a complete on-line system test procedure of the reactor trip system and that completion of. the shunt trip modification will permit on-line independent testing of the undervoltage and shunt trip attachments of the reactor trip breakers.
CONCLUSION The staff finds that the Turkey Point Plant, Units 3 and 4, is designed to permit on-line functional testing of the reactor trip system, including indepen-dent testing of the diverse trip features of the reactor trip breakers.
- Thus, the licensee meets the staff position of Item 4.5.2 of Generic Letter 83-28.
