Dear Mr. Xovach:
SUBJECT:
SAFETY EVALUATION FOR GENERIC LETTER 83 28, ITEM 4.5.3, kEACT0k TRIP RELIABILITY. ON.LINE FUNCTIONAL TESTING OF THE REACTOR TRIP SYSTEM (TAC NOS. 53994 and 53995) i Generic Letter 83 28 Item 4.5.3, required confirmation from all licensees and applicants that on line fynctional testing of the reactor trip system, including independent testing of the diverse trip feature, was being parformed.
Dy letters dated May 16. 1985 and August 6, 1985 you submitted responses to Generic Letter 83 28, item 4.5.3.
Therein you indicated your endorsement of the BWR Owners' Groups Report hiDC.30844, as being applicable to LaSalle County Station Units 1 and 2.
The NRC staff, with the assistance of our t
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 LaSalle 1 and 2 are consistent with achieving high reactor trip system availability, and the Commonwealth Edison Company response to Item 4.5.3 of Generic Letter 83 28 is therefore acceptoble for LaSalle County Station Units 1 and 2.
The enclosed safety evaluation and contractor's report (EGG-NTA 8341) provide the details and basis for our conclusion.
This completes all staff activities related to TAC Nos. 53994 and 53995.
Sincerely Original singed b>/
