| Event Text OFFICE AREA ALARM AUDIBILITY DISABLED
"On December 1, 2016, at 1014 hours (EST), the speakers for a portion of the bottom floor of Building 305, office and lunch room areas, were inadvertently disabled during construction activities to remove obsolete equipment. Special Nuclear Material (SNM) is not processed, handled, or stored within the areas where the speaker system was disabled; however, these areas require evacuation in the unlikely event of a nuclear criticality accident as described in the NFS [Nuclear Fuel Services] Emergency Plan.
"There were no actual radiological or other nuclear safety consequences. The potential consequence was that in the event of a nuclear criticality accident, evacuation could have been delayed for those personnel within these areas with a resultant increase of postulated doses. Additionally, awareness of a fire event could have been delayed for these same personnel. A series of compensatory actions were taken including restricting access to the affected areas to essential personnel, and establishing radio communications between the personnel in these areas and the personnel continuously monitoring the alarm station panel.
"On December 1, 2016, at approximately 1159 hours (EST), full compliance was restored by repairing a disabled cable in the speaker circuit and by successfully performing a speaker system test in the affected areas.
"The licensee notified the NRC Resident Inspector on. December 1, 2016." |

"On 12/08/16 at approximately 2237 [EST], the Unit 2 HPCI [High Pressure Core Injection] system failed to meet surveillance testing requirements for achieving rated flow at greater than or equal to a minimum test pressure established per the surveillance. Operations declared the HPCI system inoperable and entered Technical Specification 3.5.1 Condition C for HPCI being inoperable. Other standby systems (Reactor Core Isolation Cooling and low pressure emergency core cooling systems) are operable.
"HPCI is a single train system. Therefore, per NUREG-1022, this condition is being reported pursuant to 10 CFR 50.72(b)(3)(v)(D) as a condition that could have prevented the fulfillment of the safety function of a system required to mitigate the consequences of a design event.
"This condition has been entered into the Corrective Action program (IR 3951006). Investigation of the exact failure condition is in progress so that repairs can be made."
At the surveillance flow of 5,000 gpm, the system was approximately 80 psi below the required pressure of 1,278 psi.
Technical Specification 3.5.1, Condition C, is a 14-day Limiting Condition of Operation.
The NRC Resident Inspector will be notified. |

"On December 09, 2016 at 1734 EST, U2 Train-A NSCW [Nuclear Service Cooling Water] Transfer Pump #8 tripped during Return To Service Surveillance testing for Train-B NSCW Transfer pump #7. Technical Spec 3.7.9 Condition E entered at 1734 with Required Actions to be in M3 [mode 3, Hot Standby] in 6 hours AND M4 [mode 4, Hot Shutdown] in 12 hours. A unit shutdown was commenced at 2042 EST [as a conservative measure] to comply with TS 3.7.9 Condition E.
"At 1937, U2 B-train NSCW Transfer Pump #7 was declared operable and TS 3.7.9 Condition E was exited. The plant is currently raising power to 100%."

"On December 10, 2016 at 0848 EST, [operators at] Nine Mile Point Unit 1 manually scrammed the reactor due to high vibrations on the Main Turbine. Cause of the high vibrations is being investigated.
"Following the scram, the High Pressure Coolant Injection (HPCI) system automatically initiated as expected. At Nine Mile Point Unit 1, a HPCI system actuation signal on low reactor pressure vessel (RPV) level is normally received following a reactor scram, due to level shrink. HPCI is a flow control mode of the normal feedwater system and is not an emergency core cooling system. At 0849, RPV level was restored above the HPCI system low level actuation set point and the HPCI system initiation signal was reset. Pressure control was established on the turbine bypass valves, the preferred system. No Electromatic relief valves actuated due to this scram.
"Nine Mile Point Unit 1 is currently in Hot Shutdown, with reactor water level and pressure maintained within normal bands. Decay heat is being removed via steam to the main condenser using the bypass valves. The offsite grid is stable with no grid restrictions or warnings in effect.
"The unit is currently implementing post scram recovery procedures."
