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. 53977 AND 53978) _
Generic Letter 83-28, Item 4.5.3, required confirmation from all licensees and applicants that on-line functional testing of the reactor trip system, including independent testing of the diverse trip feature, was being performed.
By letters dated August 23, 1985, and July 20, 1990, you submitted responses to Generic Letter 83-28, Item 4.5.3. Therein you indicated your endorsement of the BWR Owner's Groups Reports NEDC 30844 and NEDC 30851P, as being applicab1e to Dresden.
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 Dresden are consistent with achieving high reactor trip system availability.
The enclosed -safet.r evaluation (Enclosure 1) and contractor's report ( EGG-NTA 8341) {Enclosure 21 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. 53977 and 53978.
