At (1010 PST) on 1/08/14, during performance of a surveillance the power supply for ten area radiation monitors in the Reactor Building was found with voltage out of specification. As a result, the affected area radiation monitors were declared non-functional. This condition represents a major loss of assessment capability and is being reported as such under 10 CFR 50.72 (b)(3)(xiii). As directed by station procedures, compensatory measures have been enacted until the power supply is restored. The Resident Inspector has been notified.

Licensee is retracting this event notification based on the following: Energy Northwest performed an evaluation for the reported out-of-specification voltage condition for the power supply to several radiation monitors in the Reactor Building. The evaluation concluded that the voltage deviation from the -24 VDC set point was small and within the calculated uncertainty for the instrument, and did not result in equipment failure. Therefore, it was concluded that the radiation monitors were functional and that the reported major loss of assessment capability did not occur. The licensee has notified the NRC Resident Inspector. Notified R4DO (Farnholtz).
