This report is being made under (10 CFR) 5 … This report is being made under (10 CFR) 50.72(b)(2)(iv)(B) for inserting a manual reactor scram due to indicated reactor water level of 205 inches and rising. The exact cause of the reactor water level increase is not known at this time. However, STP (Surveillance Test Procedure) 3.3.3.2-09, 'Reactor Water Level and Pressure Instruments Calibration' was in progress at the time and is likely the cause of the level transient.</br>In addition, this report is being made under (10 CFR) 50.72(b)(3)(iv)(A) due to PCIS (Primary Containment Isolation System) groups 2, 3 and 4 being received when reactor water level dropped below 170 inches following the reactor scram. All isolations went to completion. This level response is considered normal following a reactor scram from power and reactor water level is currently being controlled in the normal band. All PCIS group isolations were reset.</br>All rods fully inserted during the scram. The plant is in a normal shutdown electrical lineup with offsite sources powering the safety busses. No safety or relief valves lifted during the transient. Decay heat is being removed via the steam bypass to condenser valves.</br>The licensee has notified the NRC Resident Inspector.e has notified the NRC Resident Inspector. +
