i s
As defined by Technical Specifications for the Vernont Yankee Nuclear Power Station, Section 6.7. A.c, we are reporting the following i
Abnormal Occurrence as A0-73-03 and confirming our telephone conversation E
with your office.
Q At 2350 on January 15 during RHR surveillance testing, "A" Loop injection Valve (RHR-25A) failed to open, rendering the "A" LPCI E
subsysten inoperable. This inoperability of "A" LPCI subsystem exceeds i
the Liniting Condition for Operations as defined by section 3.5.A.1 of Technical Specifications. The subject section requires both LPCI
?
subsystens to be operable whenever irradiated fuel is in the reactor vessel. The reactor was operating at 1D0% power at the time of this incident.
E Initial investigation revealed that the valve notor was unusually warm and that the notor breaker had tripped. The surveillance required s
1 by'Section 4.5.A.4 of Technical Specifications was conducted.
