Dear Mr. Hukill:

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 NO. 54034)

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 letter dated August.23, 1985 you submitted the response to Generic Letter

'83-28, Item 4.5.3. Therein you indicated your endorsement of.the B&W Owners Group's Report dated April-8,1985 as being applicable to Three Mile Island Unit-

1. The NRC ' staff, with the assistance of our contractor, E.G.&G. - Idaho, has -

reviewed your response and the B&W Owners Group's Report. We conclude that the existing intervals for on-line functional testing at Three Mile Island Unit 1 are consistent with achieving.high reactor trip system availability."

The enclosed safety evaluatic,n 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 No. 54034.

Sincerely, Ro'nald W. Hernan, Senior Project Manager Project Directorate I-4 Division of Reactor Projects I/II  ;
