Event Text
MANUAL REACTOR TRIP
"This 4 and 8 hour notification is being made to report that Salem Unit 2 initiated a manual reactor trip and subsequent automatic Auxiliary Feedwater system actuation. The trip was initiated due to a 21 Reactor Coolant Pump reaching its procedural limit for motor winding temperature of 302F.
"Salem Unit 2 is currently stable in Mode 3. Reactor Coolant system pressure is 2235 PSIG and Reactor Coolant System temperature is 547 F with decay heat removal via the Main Steam Dump and Auxiliary Feedwater Systems. Unit 2 has no active shutdown technical specification action statements in effect. All control rods inserted on the reactor trip. All ECCS [emergency core cooling systems] and ESF [emergency safety function] systems functioned as expected.
"No safety related equipment or major secondary equipment was tagged for maintenance prior to this event. No personnel were injured during this event."
The NRC Resident Inspector was notified. The Lower Alloways Creek Township will be notified.
