"A momentary alarm for loss of HPCS system DC control power was received in the NMP2 control room. Troubleshooting has determined that a loose connection existed at a fuse block in the DC control power circuitry. The HPCS system was declared inoperable and Technical Specification 3.5.1, Condition B, was entered at 1715. In accordance with Condition B, the Reactor Core Isolation Cooling (RCIC) system was verified to be operable.

"Repairs were subsequently completed and the HPCS system has been declared operable as of 2046."
