| ENS 46241 | 10 September 2010 00:29:00 | On September 9, 2010, at approximately 2129 hours (EDT), Indian Point 3 manually tripped the reactor from the control room following indications of a service water leak in the Main Generator Exciter housing. Unit 3 is currently stable in mode 3. All automatic actions occurred as required. All control rods fully inserted. No primary or steam generator safety relief valves lifted. The motor driven auxiliary feedwater pumps automatically started on low steam generator level as designed. Decay heat removal is via the steam generators to the main condenser. Offsite power is available and supplying all safeguards busses. Unit 2 is unaffected and remains in Mode 5 in a forced outage for 21 RCP (Reactor Coolant Pump) repair. During the Fast Bus Transfer (the) 34 Reactor Coolant Pump tripped. The cause is being investigated. There was an inadvertent release of CO2 to 31 Main Boiler Feed Pump. The cause was due to the suction relief valve lifting which has subsequently reseated. The NRC Sr. Resident Inspector and New York State Public Service Commission have been notified. The reactor is currently being maintained at normal operating temperature and pressure. |
| ENS 44048 | 8 March 2008 21:23:00 | On March 8, 2008, at 1937 hours, Emergency Planning determined that 17 of a total of 156 sirens were reported as unavailable due to weather related loss of power as a result of high winds. In accordance with the Indian Point reporting procedure, the loss of 16 or more sirens that can not be returned to service in one hour, constitutes a major loss of the offsite notification capability that requires an 8-hour non-emergency notification in accordance with 10 CFR 50.72(b)(3)(xiii). Actions are underway to restore all of the sirens to service. As of 2043 EST on 03/08/08 there were 16 of 156 sirens out of service. The licensee notified the NRC Resident Inspector, as well as the Counties of Westchester, Putnam, Rockland, and Orange. The licensee also notified the Public Service Commission. |
| ENS 41734 | 28 May 2005 18:45:00 | At 1305 hours (EDT) on 5/28/05, the Plant Integrated Computer (PICS) failed. This process computer provides Safety (Parameter) Display System (SPDS) and Emergency Response Data System (ERDS). Troubleshooting efforts and repairs were performed and ERDS/SPDS were returned to service at 15:55 (hrs.) on 5/28/2005. All redundant plant data indicators, annunciators and recorders functioned normally during the PICS outage. The licensee will be notifying the New York State Public Service Commission and the NRC Resident Inspector. |
