Dear Mr. Fitzpatrick:

SUBJECT:
GENERIC LETTER 83-28, ITEM 4.5.3, REACTOR TRIP SYSTEM FUNCTIONAL TESTING'(TACNO.54008)
'GPU Nuclear Corporation-(GPUN/the licensee) was required by. Generic letter 83-28. Item 4.5.3 to perform on-line functional testing of the reactor-trip system, including independent testing of the diverse 1 trip. features. Existing.
intervals for on-line functional testing required by Technical Specifications-were to be reviewed to determine that the intervals are consistent with achieving high reactor trip s considerations such as:. (1) ystem availability when accounting for:.
H uncertainties in component failure rates; _(2)
L
. uncertainty in common mode failure rates (3)' reduced redundancy during testing; (4) operator errors during testing; and (5) component "wearout". caused by the L
testing.
In letters' dated August 16, 1984,' November 1984 and-October 23, 1985, GPUN' provided information including GE Owners Group Topical Report NEDC-30844 regarding Item 4.5.3 of. Generic Letter 83-28.
The NRC' staff and our contractor (EG&G) have reviewed this information. The results of these reviews as documented in the enclosed contractor's. report' (EGG-NTA-8341) find that existing. intervals.for on-line functional. testing are consistent with' achieving high reactor trip system availability. The enclosed SafetyEvaluation(SE)'documentsourconcurrencewiththecontractor's.
findings. We, therefore, consider Item 4.5.3 of Generic Letter 83-28 to be closed.
Sincerely,
/s/
Alexander W. Dromerick, Project Manager Project Directorate I-4 Division of Reactor Projects I/II Office of Nuclear Reactor Regulation
