Dear Mr. Kovach:
SUBJECT:
SAFETY EVALUATION FOR GENERIC LETTER 83-28, ITEM 4.5.3, REACTOR TRIP RELIABILITY - ON-LINE FUNCTIONAL TESTING OF THE REACTOR TRIP SYSTEM (TAC NOS. 54017 AND 54018).
Generic Letter 83-28. Item 4.5.3..' required confirmation from all licensees and applicants that en-line functional testing of the reactor trip system, including independent tuting of the diverse trip feature, was being performed.
By letters dated August 23, 1985, and May 1, 1990, you submitted responses to Generic Letter 83-28. Item 4.5.3.
Therein you indicated your endorsement of the BWR Owner': Groups Reports NEDC 30844 and NEDC 30851P, as being applicable to Quad Cities. The NRC staff, with the assistance of our contractor, Idaho National Engineering Laboratory, has reviewed your responses and the BWR Owners Group's report. We conclude that the existing intervals for on-line functional testing at Quad Cities are consistent with achieving high reactor trip system availability.
The enclosed safety evaluation and contractor's report (EGG-NTA 8341) provide the details and basis for our conclusion. Therefore, we consider Generic Letter 83-28 Item 4.5.3 to be complete.
This completes all staff activities related to TAC Nos. 54017 and 54018.
Sincerely.
