The highest net radiation reading was 10 microR/hr. The vehicle returned to Millbury where, on 2/6/13, one device (described as a WWII "Blackout Button" measuring ~1.75 inch diameter and containing ~10 microCuries Radium-226) was located and removed from load by an independent consultant and isolated in secure storage for further processing. The remaining load re-shipped to Henderson without further incident. On 2/13/13, the device was removed, packaged and shipped to a proper disposal site by a third-party waste broker. The original owner was not determined. "The Agency [MA Radiation Control Program] considers this matter closed."

The cause of the loss of vacuum was a significant leak on the 1C feedwater heater level control line. The leak appeared as a steam/water leak near the penetration to the main condenser. As extraction steam was isolated, condenser vacuum deteriorated and was approaching the turbine trip setpoint, at which time the reactor was manually scrammed. Condenser vacuum recovered following the scram. MSIVs [Main Steam Isolation Valves] are open, main turbine bypass valves are controlling reactor pressure and reactor feedwater pumps are being used to control reactor water level. "All expected containment isolation and initiation signals (Groups 2, 3, 6, and 8) were received. Upon receipt of these signals all required components actuated as required. In response to the scram, all plant equipment responded as designed. The reactor had been operating near 95% power for several hours due to the 1C3 heater isolating at 2334 [hrs. CDT] on 3/18/13. "This event is reportable within 4 hours per 10CFR50.72(b)(2)(iv)(B) `any event or condition that results in actuation of the reactor protection system (RPS) when the reactor is critical except when the actuation results from and is part of a pre-planned sequence during testing or reactor operation.' It is also reportable within 8 hours per 10CFR50.72(b)(3)(iv)(A) and requires an LER within 60 days per 10CFR50.73(a)(2)(iv)(A)." All rods inserted into the core during the scram. No safety relief valves lifted during the transient. The plant is in its normal shutdown electrical lineup. The licensee has notified the NRC Resident Inspector. | Power Reactor | Event Number: 48830 | Facility: KEWAUNEE Region: 3 State: WI Unit: [1] [ ] [ ] RX Type: [1] W-2-LP NRC Notified By: SCOTT CIESLEWICZ HQ OPS Officer: STEVE SANDIN | Notification Date: 03/19/2013 Notification Time: 10:00 [ET] Event Date: 03/19/2013 Event Time: 08:30 [CDT] Last Update Date: 03/19/2013 | Emergency Class: NON EMERGENCY 10 CFR Section: 50.72(b)(3)(xiii) - LOSS COMM/ASMT/RESPONSE | Person (Organization): DAVE PASSEHL (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 TSC VENTILATION REMOVED FROM SERVICE FOR PLANNED MAINTENANCE "On March 19, 2013, at 0830 hours [CDT], the Kewaunee Power Station Technical Support Center (TSC) ventilation system was removed from service for planned TSC ventilation system maintenance. The removal of the ventilation system potentially affects the TSC habitability during a declared emergency requiring activation. The Emergency Response Organization (ERO) team has been notified of the maintenance and the possible need to relocate during an emergency. If an emergency is declared and TSC ERO activation is required, the TSC will be staffed and activated unless the TSC becomes uninhabitable due to ambient temperatures, radiological, or other conditions. If relocation of the TSC staff becomes necessary, the Station Emergency Director will relocate the staff to an alternate TSC location. "The ventilation system is expected to be out of service for approximately 5 hours. "This condition is being reported in accordance with 10CFR50.72(b)(3)(xiii) as an event that results in a major loss of emergency assessment capability. "The NRC Resident Inspector has been notified." | Power Reactor | Event Number: 48832 | Facility: VOGTLE Region: 2 State: GA Unit: [ ] [2] [ ] RX Type: [1] W-4-LP,[2] W-4-LP NRC Notified By: HANS BISHOP HQ OPS Officer: BILL HUFFMAN | Notification Date: 03/20/2013 Notification Time: 03:15 [ET] Event Date: 03/20/2013 Event Time: 02:46 [EDT] Last Update Date: 03/20/2013 | Emergency Class: UNUSUAL EVENT 10 CFR Section: 50.72(a) (1) (i) - EMERGENCY DECLARED | Person (Organization): DANIEL RICH (R2DO) SCOTT MORRIS (IRD) LOUISE LUND (NRR) VICTOR McCREE (R2 R) ERIC LEEDS (NRR) | Unit | SCRAM Code | RX CRIT | Initial PWR | Initial RX Mode | Current PWR | Current RX Mode | 2 | N | N | 0 | Defueled | 0 | Defueled | Event Text UNUSUAL EVENT DECLARED BASED ON INDICATION OF FIRE WITHIN PROTECTED AREA The licensee declared a Unusual Event based on EAL HU-2 due to indication of a fire in the Protected Area for greater than 15 minutes. The licensee received initial indication of a fire alarm and startup of fire water pumps. The alarm was located in the vicinity of the Auxiliary Building Unit 2 HVAC supply unit. The licensee declared an unusual event at 0246 EDT. Upon investigation, it was determined that the heater strips in an HVAC unit were overheated and caused a fire alarm and no fire actually existed. The licensee notified state and local agencies and will notify the NRC Resident Inspector. Notified DHS, FEMA, DHS NICC and NuclearSSA (email). * * * UPDATE AT 0409 EDT ON 3/20/13 FROM BISHOP TO CROUCH * * * The licensee terminated its unusual event at 0341 EDT on 3/20/13 after confirming there was no fire within the Unit 2 Auxiliary Building HVAC supply unit. The licensee notified state and local agencies and will notify the NRC Resident Inspector. R2DO (Rich) and NRR EO (Lund) notified. Notified DHS, FEMA, DHS NICC and NuclearSSA (email). | |
