Event Text
SOLENOID FAILED TO RELEASE AIR PRESSURE FOLLOWING REACTOR PULSE

The licensee reported that, following a pulse of the reactor, the transient control rod failed to reinsert into the core within 15 seconds, as required by the Technical Specifications. The licensee determined that the solenoid valve for this control rod had become mechanically bound by foreign material (dried grease) within the valve. The licensee has cleaned and successfully tested the solenoid valve.

The licensee made this report in accordance with their Technical Specifications as a "failure of a safety system component that could render the system incapable of performing the safety function."
