RPS ACTUATION WHILE CRITICAL
"On 5/18/03 with the reactor at 28 percent power in MODE 1, an unplanned actuation of the reactor protection system occurred. At 1807 the reactor was automatically tripped from a turbine trip - reactor trip signal. All systems functioned as required and no other safety systems were actuated. The operations staff responded to the event in accordance with applicable plant procedures. The plant stabilized at normal operating no-load Reactor Coolant System temperature and pressure following the reactor trip. The cause of the turbine trip is under investigation.
"This condition is being reported as an unplanned reactor protection system actuation in accordance with 10 CFR 50.72(b)(2)(IV)(B) and 10 CFR 50.72(b)(3)(iv)(A)."
All rods fully inserted and decay heat is being removed via the PORV's.
The licensee notified the NRC Resident Inspector.
