Title	Failure of 250V Dc Hpci Injection Valve Undervoltage Relay
Event Description	A 250 Volt DC undervoltage relay for HPCI injection valve MO-2301-8 failed. The reason for the failure is still under investigation. The injection valve is a normally closed valve that opens on an initiation signal. The failure of the under voltage relay would prevent the HPCI injection valve (MO-2301-8) from opening and would prevent HPCI from performing its safety function. Pilgrim Station has entered a 14 day LCO due to Technical Specification 3.5.C.2. The NRC Resident Inspector has been notified.
