| ENS 45552 | 9 December 2009 14:55:00 | On December 9, 2009, at approximately 1101 EST, as a result of a scheduled full-volume test of the Indian Point Energy Center (IPEC) Alert Notification System (ANS), using microwave/radio activation pathway only, 37 of 172 sirens did not pass the test. The siren system was then configured to the normal configured (TCP/IP and microwave/radio activation pathways) and the siren system retested successfully following a silent test at approximately 1147 EST. The system is capable of being used to notify the public in an emergency. Prior to the full volume test today, a previous silent test using the radio/microwave pathway was successful. As a result of the 37 sirens that did not pass the test today, a press notice was provided. This courtesy notification is being provided under 10CFR50.72(b)(2)(xi). The condition was recorded in the IPEC corrective action program. The event remains under investigation. The licensee notified the NRC Resident Inspector and FEMA. Additionally Westchester, Orange, Putnam, and Rockland counties were notified. |
| ENS 45354 | 16 September 2009 17:10:00 | On September 16, 2009, at approximately 1036 hours, as a result of a regularly scheduled test of the Indian Point Energy Center (IPEC) Alert Notification System (ANS) 18 of 172 sirens did not pass the test. The sirens were not tested and declared as functional within one hour and in accordance with the reporting guidelines the event is reportable under 10CFR50.72(b)(3)(xiii) as a major loss of offsite response capability (i.e., a loss of 10% or more of the total number of sirens for more than one hour). Preliminary investigations and troubleshooting determined 14 sirens failed to indicate via the ANS computer system successful siren activation due to an incorrect software data adjustment for these 14 sirens. ANS technicians corrected the software error for these 14 sirens and are continuing to investigate the cause of the failure of the remaining 4 sirens to activate. To validate that the software error for the 14 sirens was corrected, a functional test of 1 of the 14 sirens was conducted. The test indicated the siren was functional but investigation and troubleshooting is continuing to validate this. Reverse 911 has been and remains available to alert the public should there be an actual event requiring the ANS. The condition was recorded in the IPEC corrective action program. The event remains under investigation. The licensee notified the NRC Resident Inspector.
Two sirens were repaired making a total of 156 sirens operable. No further reporting is forthcoming. Licensee has notified the NRC Resident Inspector. The R1DO (Don Jackson) was notified. |
| ENS 43016 | 30 November 2006 19:00:00 | On November 30, 2006, at approximately 14:45 hours, an Auxiliary Feed Water (AFW) System actuation signal was generated as a result of maintenance activities on the 21 Main Boiler Feed Pump (MBFP). Both motor driven AFW pumps were running at the time and were not automatically started due to previously being placed in service to provide feed water flow to the steam generators. The actuation signal isolated the Steam Generator blowdown Containment Isolation Valves. Both MBFPs were isolated and not feeding the steam generators at the time the actuation signal was generated. The plant was in Mode 3 (Hot Standby) for a forced outage and 21 MBFP was in a maintenance / test condition. The automatic actuation occurred due to the reset oil pressure lowering below the trip set point and initiating an automatic actuation signal. The licensee notified the NRC Resident Inspector.
At 2100 on 11/30/2006, as a result of continuing work activities on the 21 MBFP an AFW System actuation signal was generated. Both motor driven AFW pumps were running at the time and were not automatically started due to previously being placed in service to provide feed water flow to the steam generators. 21 MBFP has been successfully placed in service." The NRC Resident Inspector was notified of this update by the licensee. Notified R1DO (James Dwyer). |
| ENS 42993 | 15 November 2006 16:26:00 | On November 15, 2006, at 14:00 hours, an automatic reactor trip occurred during troubleshooting of the Main Generator Exciter Generrex power supply, when an electrical spike resulted in a turbine trip which caused a reactor trip. All control rods fully inserted and safety equipment operated as expected. The Auxiliary Feedwater (AFW) System actuated as expected as a result of a low steam generator level from the reactor trip and started the motor driven AFW pumps. The Emergency Diesel Generators did not start as offsite power remained available. The plant was stabilized in hot standby with decay heat being removed by the main condenser. There were no radiation releases. The condition is under investigation and a post trip review is being conducted. No PORVs or SG safety valves lifted during the event. The electrical plant is in a normal shutdown lineup and the EDGs are operable in standby. There was no affect on Unit 3 operation due to this event. The licensee notified the NRC Resident Inspector, and stated that IPEC communications has transmitted an IPEC Status Report which provides a status to local, state, and federal agencies. |
| ENS 42849 | 19 September 2006 16:08:00 | On September 19, 2006, at approximately 1208 hours, the Emergency Planning Department in conjunction with the Indian Point Energy Center (IPEC) Information Technology (IT) Department determined that all of the 156 sirens in the IPEC Emergency Planning Zone were unavailable due to an inability to activate the sirens through the siren computer operating system. The siren computer operating system was unavailable due to its Oracle Database not responding to a restart command during a routine bi-weekly reboot and preventive maintenance activity. Actions were initiated to recover the siren computer operating system and at approximately 1310 hours, the system was determined to be recovered and a test verified that all 156 sirens could be activated. In accordance with the IPEC 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). The Emergency plan has route alerting and public radio announcement available as necessary to notify the public during the time the sirens were not capable of being activated. The condition was recorded in the IPEC corrective action program and actions initiated to investigate and correct the condition. The cause of the failure of the Oracle Database not responding is unknown at this time. The licensee notified the NRC Resident Inspector and the State and Local Emergency Planning organizations. |
| ENS 41924 | 17 August 2005 17:14:00 | A non-licensed Entergy headquarters acting supervisor (badged at Indian Point) had a confirmed positive for alcohol during a follow-up fitness-for-duty test. The employee's access authorization has been terminated. Contact the Headquarters Operations Officer for additional details. The licensee notified the NRC Resident Inspector. |
| ENS 41353 | 24 January 2005 16:07:00 | A non-licensed plant employee was determined to be under the influence of alcohol during a test conducted for cause. The employee's access to the plant has been terminated. Contact the Headquarters Operations Officer for additional details. The licensee has notified the NRC Resident Inspector. |
