| Event Text AGREEMENT STATE REPORT - GAUGE SHUTTER FAILURE
The following information was received via email from Arkansas Department of Health:
"The licensee notified the [Arkansas] Department [of Health] on December 27, 2013 via email that a Ronan source holder model SA1-F37 shutter failed. The source holder serial number is M4785, and the source contains 100 mCi of Cesium-137. The problem was discovered during shutter checks. [According to the licensee], it appears the shutter handle is spinning on the shaft that rotates [to] open [and] close the shutter. [This] may be a result of a sheared pin that connects the handle to the shaft. Per the RSO, the gauge is still in use, and there have been no exposures to employees or members of the public. The RSO has notified applicable facility personnel.
"The licensee indicated the manufacturer was contacted on December 27, 2013 and repairs should be performed the week of January 6th-13th.
"The State of Arkansas is awaiting a written report after repairs. The State's event number is ARK-2013-013." |

"While operating in Mode 1 at 100% rated thermal power, the City of Burlington Kansas emergency dispatch center notified Wolf Creek Nuclear Operating Corporation (WCNOC) Security that two emergency plan sirens in Burlington, Kansas and one emergency plan siren in New Strawn, Kansas failed to function when they were actuated to call out a local fire response . These three sirens also function as part of the Emergency Plan Alert and Notification System. WCNOC Emergency Plan personnel have been notified of the three siren failures and the cause is under investigation.
"Wolf Creek Generating Station (WCGS) remains at 100% rated thermal power.
"The WCGS NRC Resident [Inspector] has been notified and local government."

"At 0245 CST secondary containment differential pressure exceeded the Technical Specifications limit due to a personnel error manipulating an incorrect component. This caused entry into LCO 3.6.4.1 for secondary containment inoperability. An event or condition that could have prevented fulfillment of a safety function requires an 8 hour report per 10CFR50.72(b)(3)(v)(C) for Control of Rad Release and 10CFR50.72(b)(3)(v)(D) for Accident Mitigation. The error was corrected and secondary containment pressure was restored to greater than or equal to 0.25 inch vacuum water gauge and secondary containment was declared operable at 0302 CST. The NRC Resident has been informed of this condition." |

"At 1659 EST hours on January 6, 2014, Beaver Valley Power Station Unit 1 automatically tripped from 100% power. The cause of the reactor trip was a main transformer differential trip. All rods fully inserted into the core and the plant is stable in Mode 3. All three auxiliary feedwater pumps automatically started as expected. Normal and Emergency Busses are being powered by Offsite Power. The cause of the main transformer differential trip is being investigated. All other equipment functioned as expected. At 1757 EST hours the Emergency Operating Procedures were exited.
"Resident inspector has been notified."
Decay heat is being removed via the turbine bypass valves to the condenser. No primary or secondary safety valves lifted. Unit 2 was unaffected.
Licensee notified the States of Pennsylvania, Ohio, and West Virginia and the Counties of Beaver, PA, Hancock, OH, and Columbiana, OH. |

"On January 6th, 2014 at 2115 EST Indian Point Unit 3 experienced an Automatic Reactor Trip due to '33 Steam Generator Steam flow/Feed flow Mismatch.' Operators entered emergency procedure E-0, Reactor Trip or Safety Injection. All control rods fully inserted, all safety systems responded as expected, and off-site power remained in-service. No primary or secondary safety valves actuated due to the trip. This is reportable under 10CFR50.72(b)(2)(iv)(B). The main condenser is being used for heat sink. Unit 2 remains stable at 100% power.
The Auxiliary Feedwater System actuated following the automatic trip as expected. This is reportable under 10CFR50.72(b)(3)(iv)(A).
"Investigation is underway to determine the cause of the 33 Steam Generator Mismatch condition."
The licensee will inform local and other government agencies and issue a press release. The licensee has informed the State of New York and the NRC Resident Inspector. | |
