ENCLOSURE 3 SAFETY EVALUATION I
DOCKET NO. 50-302 CRYSTAL RIVER UNIT 3 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 Novenber 4,1983, the licensee, Florida Power Corporation, 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 Florida Power Corporation performs on-line testing of the reactor trip system (RTS) and that the RTS circuitry will be modified to permit independent on-line testing of the undervoltage and shunt trip attachments of the reactor trip breakers.
CONCLUSION
.The staff finds that Crystal River Unit 3 will be designed to permit on-line functional testing of the reactor trip system, including independent testing of the diverse trip features of the reactor trip breakers. Thus, the licensee neets the staff position of Item 4.5.2 of Generic Letter 83-28.
