The plant is currently in the process of determining the cause of the failure. Normal power to the TSC is currently available." The licensee notified the NRC Resident Inspector. * * * UPDATE FROM KEVIN HUBER TO VINCE KLCO ON 10/21/2011 AT 1502 EDT * * * "The TSC Emergency Diesel Generator failure has been identified and corrected. The unit has been successfully tested, restoring the TSC Emergency Diesel Generator and TSC to a functional status." The licensee has notified the NRC Resident Inspector. Notified the R3DO (Hills). | Power Reactor | Event Number: 47364 | Facility: MONTICELLO Region: 3 State: MN Unit: [1] [ ] [ ] RX Type: [1] GE-3 NRC Notified By: TOM PROELL HQ OPS Officer: VINCE KLCO | Notification Date: 10/21/2011 Notification Time: 16:42 [ET] Event Date: 10/21/2011 Event Time: 12:50 [CDT] Last Update Date: 10/21/2011 | Emergency Class: NON EMERGENCY 10 CFR Section: 50.72(b)(2)(iv)(B) - RPS ACTUATION - CRITICAL 50.72(b)(2)(xi) - OFFSITE NOTIFICATION 50.72(b)(3)(iv)(A) - VALID SPECIF SYS ACTUATION | Person (Organization): DAVID HILLS (R3DO) | Unit | SCRAM Code | RX CRIT | Initial PWR | Initial RX Mode | Current PWR | Current RX Mode | 1 | A/R | Y | 100 | Power Operation | 0 | Hot Shutdown | Event Text AUTOMATIC REACTOR SCRAM DUE TO LOCKOUT OF AUXILIARY POWER TRANSFORMER "The station experienced a lockout of the 2R Auxiliary Power Transformer. The resulting transient caused an automatic actuation of the RPS system. All control rods fully inserted. A Group 2 Primary Containment isolation occurred. Both 11 and 12 Emergency Diesel Generators started on a loss of voltage signal. Equipment response was that the 11 ESW [Emergency Service Water] pump (cooling for the #11 Emergency Diesel) failed to develop required pressure. The #13-4160V non-safety related bus failed to restore after the transient [and feed the Division 1 Essential Bus]. Additionally, the #15 bus transferred to the 1AR transformer [and is feeding the Essential Bus]." The #11 Emergency Diesel Generator is currently tagged out of service. Electrical supply is being provided by offsite power. Reactor heat is being removed through the main steam line to the main condenser and reactor water inventory is being provided by the feedwater system. The SRVs lifted and reseated. The HPCI system was manually place into a pressure control mode. The Minnesota Pollution Control Agency is being notified due to the licensee violating the site discharge canal temperature rate of change limit. The licensee notified the NRC Resident Inspector. | Fuel Cycle Facility | Event Number: 47365 | Facility: LOUISIANA ENERGY SERVICES RX Type: Comments: URANIUM ENRICHMENT FACILITY GAS CENTRIFUGE FACILITY Region: 2 City: EUNICE State: NM County: LEA License #: SNM-2010 Agreement: Y Docket: 70-3103 NRC Notified By: CHARLES SLAMA HQ OPS Officer: PETE SNYDER | Notification Date: 10/21/2011 Notification Time: 17:05 [ET] Event Date: 08/24/2011 Event Time: [MDT] Last Update Date: 10/21/2011 | Emergency Class: NON EMERGENCY 10 CFR Section: 21.21 - UNSPECIFIED PARAGRAPH | Person (Organization): MARK LESSER (R2DO) DOUG WEAVER (NMSS) PART 21 GROUP (EMAI) | Event Text POTENTIALLY UNDERSIZED WELDS ON CENTRIFUGE T-COLUMN BASE PLATE CONNECTORS Name of the firm constructing or supplying the basic component which contains the deviation or fails to comply: Engineered Products Department PO Box 2138 Carlsbad, NM 88221 Description of the deviation or failure to comply which is being evaluated : Undersized welds were identified on centrifuge T-column to base plate connectors which are still in construction. The welds do not comply with AWS 01.1 and are currently being evaluated for the potential to cause substantial safety hazards. An extent of condition is in progress to identify any further conditions and to provide weld dimensions to the design agent for engineering analysis. This analysis will determine the ability of the steelwork to perform per design requirements. The date on which the information of suspect deviation defect or failure to comply was obtained: 24 August, 2011 The date on which the evaluation is expected to be complete: 23 November, 2011 | Power Reactor | Event Number: 47366 | Facility: PERRY Region: 3 State: OH Unit: [1] [ ] [ ] RX Type: [1] GE-6 NRC Notified By: DAVID STANLEY HQ OPS Officer: VINCE KLCO | Notification Date: 10/21/2011 Notification Time: 20:25 [ET] Event Date: 10/21/2011 Event Time: 17:20 [EDT] Last Update Date: 10/21/2011 | Emergency Class: NON EMERGENCY 10 CFR Section: 50.72(b)(2)(xi) - OFFSITE NOTIFICATION OTHER UNSPEC REQMNT | Person (Organization): DAVID HILLS (R3DO) | Unit | SCRAM Code | RX CRIT | Initial PWR | Initial RX Mode | Current PWR | Current RX Mode | 1 | N | Y | 100 | Power Operation | 100 | Power Operation | Event Text OFFSITE NOTIFICATION DUE TO FUEL OIL SPILL "This event is being reported in accordance with 10CFR50.72(b)(2)(xi). On October 21, 2011, at approximately 1723 hours EDT, notification of a fuel oil spill was made to the US Environmental Protection Agency (EPA), National Response Center. At the time of the event, the plant was in Mode 1 at 100 percent rated thermal power. The fuel oil spill was caused by a leak in an underground pipe outside the protected area, but inside the owner controlled area. The spill is estimated between 1000 to 1500 gallons and is contained onsite. However, a certified wetlands specialist was contacted and determined the area met the criteria for wetlands designation, which in turn made the event reportable. Clean Harbors Incorporated is assisting with the onsite clean-up and remediation. "Additionally, the Ohio EPA: State Emergency Response Commission, Perry Township Fire Department, Lake County Emergency Planning Committee, and the U.S. Coast Guard were notified in accordance with plant procedures. This event is also being reported in accordance with the plant's Operating License, Appendix B, Environmental Protection Plan, which states, in part, that any occurrence of an unusual or important event that indicates or could result in significant environmental impact causally related to plant operation shall be recorded and reported to the NRC within 24 hours followed by a written report." The licensee notified the NRC Resident Inspector. | Power Reactor | Event Number: 47367 | Facility: SUSQUEHANNA Region: 1 State: PA Unit: [1] [2] [ ] RX Type: [1] GE-4,[2] GE-4 NRC Notified By: GORDON ROBINSON HQ OPS Officer: JOE O'HARA | Notification Date: 10/22/2011 Notification Time: 01:56 [ET] Event Date: 10/21/2011 Event Time: 08:57 [EDT] Last Update Date: 10/22/2011 | Emergency Class: NON EMERGENCY 10 CFR Section: 26.719 - FITNESS FOR DUTY | Person (Organization): BLAKE WELLING (R1DO) | Unit | SCRAM Code | RX CRIT | Initial PWR | Initial RX Mode | Current PWR | Current RX Mode | 1 | N | Y | 99 | Power Operation | 99 | Power Operation | 2 | N | Y | 99 | Power Operation | 99 | Power Operation | Event Text FITNESS FOR DUTY RULE NOT MET "At 0857 on 10/21/2011 a condition was reported identifying that 10CFR Part 26 requirement for the FFD Lab Director to be subject to the FFD Rule was not met for the period of 12/12/2010 to 4/28/2011.
