AUTOMATIC REACTOR SCRAM WHILE PERFORMING SCHEDULED SHUTDOWN
"During a reactor shutdown for scheduled maintenance, a full reactor scram was generated from the Nuclear Instrumentation System.
"IRMs [Intermediate Range Monitoring detectors] 13, 14 and 18 spiked causing scram signals in both RPS [Reactor Protection Systems].
"All systems functioned properly post scram, all operator actions were correct. Holding reactor pressure at 900 psig to perform leakage inspection. Following [the leakage] inspection [operations intend] to proceed to cold shutdown."
All control rods inserted fully into the core and excess decay heat is currently being diverted to the main condenser, as necessary.
The licensee notified the NRC Resident Inspector.
