Gentlemen:
Thank you for your letter of October 16, 1985, in response to our letter and
Notice of Violation dated September 16, 1985. We have reviewed your reply and
find it responsive to the concerns raised in our Notice of Violation. We also
understand your question concerning interpretation of the applicability of
10 CFR 50.72 and 10 CFR 50.73 to single plant protection system actuations.
By separate correspondence we have requested NRR to provide an interpretation
of your Technical Specifications, paragraph 2.9, with regard to reporting of
circulator trips. Until such an interpretation is received, the reporting
-requirements must be literally followed.
Your letter also discussed the reportability of the RWP system, making the
point that these should be considered in the same manner as circulator trips.
RWPs were not a part of the violation. Additionally, it was our understanding
that you were ' reviewing the trip points for the RWP system and were
considering whether these could be modified to preclude excess actuation.
Since the RWP system serves to preclude excess reactivity addition rates, we
do not consider them to be the same as the single circulator trips.
They
should be reported.
