RPS LOGIC ACTUATION WHILE SHUTDOWN
"At 0315 on March 21, 2002, during Refueling at Nine Mile Point Unit 2, an actuation of the Reactor Protection System (RPS) logic occurred when air was lost to the scram air header.
"The RPS logic actuation was caused by high water level in the Scram Discharge Volume (SDV) as a result of loss of motive air to control rod scram valves. The loss of air was experienced as a result of incorrectly written procedure step sequence while securing the plants Instrument Air system.
"This event is reportable under 10CFR50.72 (b)(3)(iv)(A), Any event or condition that results in valid actuation of the Reactor Protection System (RPS)."
The NRC Resident Inspector was notified.
