AUTOMATIC REACTOR SCRAM FOLLOWING TURBINE TRIP ON HIGH MOISTURE SEPARATOR LEVEL
"While operating at 76% power on 12/5/13 at 0325 EST, the main turbine tripped on moisture separator hi level. The reactor scrammed along with the main turbine trip. All safety systems responded as designed and expected. There was no radiological release. There were no injuries.
"During the scram, all rods inserted into the core. Plant is stable in Mode 3 in its normal S/D [shutdown] electrical line up. Decay heat is being removed via the turbine bypass valves dumping steam to the main condenser.
"At 0505 EST while securing from cooldown in an attempt to start a recirc pump, BPVs [Bypass Valve] opened causing reactor level swell and subsequent shrink. During this time, RPV [Reactor Pressure Vessel] level lowered to below RPV level 3 and caused a RPS [Reactor Protection System] actuation. RPV level was recovered and is now stable in normal band."
The licensee has notified the NRC Resident Inspector.

"This update to ENS #49608 adds reporting criterion 10CFR50.72(b)(3)(iv)(A) for the RPS actuation at 0505 EST during post-scram recovery."
The licensee notified the NRC Resident Inspector and the Lower Alloways Creek township. The licensee will be making a press release.
