UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D. C. 20555 ENCLOSURE SAFETY EVALUATION DOCKET NOS. 50-280/281 SURRY POWER STATION, UNITS 1 AND 2 GENERIC LETTER 83-28, ITEM 4.5.2 REACTOR TRIP SYSTEM RELIABILITY-ON-LINE TESTING INTRODUCTION AND
SUMMARY
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 st~ff 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 lttter dated November 4, 1983, the licensee, Virginia Electric and Power 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 at Surry independent testing of the diverse trip features is part of the Preventative Maintenance Program, and that Item 4.5.2 of Generic Letter 83-28 is not applicable.
Item 4.5.2 is not applicable because Surry is desi'gned to permit on-line testing of the reactor trip system, including independent testing of diverse trip features of the reactor trip breakers. The staff has confirmed this to be true through review of Item 4.3 of Generic Letter 83-28, and review of the Surry Technical Specifications.
CONCLUSION The staff finds that the Surry Power Station, Units 1 and 2, is designed to permit on-line functional testing of the reactor trip system, includirig inde-pendent 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.
