Region: 4 City: RENO State: NV County: License #: 00-11-0409-02 Agreement: Y Docket: NRC Notified By: SNEHA RAVIKUMAR HQ OPS Officer: DONG HWA PARK | Notification Date: 02/04/2014 Notification Time: 14:38 [ET] Event Date: 10/14/2013 Event Time: [PST] Last Update Date: 02/04/2014 | Emergency Class: NON EMERGENCY 10 CFR Section: AGREEMENT STATE | Person (Organization): RAY AZUA (R4DO) FSME EVENTS RESOURCE (EMAI) | Event Text SUSPECTED LOCKING MECHANISM FAILURE ON AN INDUSTRIAL RADIOGRAPHY CAMERA The following was received from the State of Nevada via email: "The plunger lock on Camera 880 D (SN: D9686) spun freely in the locked position and could not be unlocked. It was tagged as inoperable and locked away in the safe. "On November 15, 2013, the camera was shipped to QSA Global, Inc., for repair. The camera was repaired on November 19, 2013 and returned to the licensee. It was then verified that all its parts including the plunger, lock and locking mechanism were working correctly. The camera was inspected and found to be fine on January 22, 2014, by one of our staff from the Radiation Control Program. The incident is closed."

"Specifically, an assumed Appendix R fire in rooms 713.0-A28, 737.0-A1A, 757.0-A2, 757.0-A5, 757.0-A9, 772.0-A1, 772.0-A2, or 772.0-A5 could result in spurious operation of multiple components in the normal and emergency charging flow paths. Westinghouse's analysis indicates the required time to isolate the normal charging path is approximately two minutes, securing the second charging pump is approximately four minutes and isolating the emergency charging path is approximately 12.5 minutes. "Based on this preliminary analysis, WBN procedures are non-conservative since they require these actions to be completed in 18 minutes. "TVA has verified that potentially impacted Appendix R equipment remains functional; however, a compensatory fire watch has been established for the above listed areas. This immediate action will ensure that the approved Appendix R Fire Safe Shutdown Plan can be achieved." The licensee has notified the NRC Resident Inspector. | Power Reactor | Event Number: 49819 | Facility: MONTICELLO Region: 3 State: MN Unit: [1] [ ] [ ] RX Type: [1] GE-3 NRC Notified By: DAMON HESSIG HQ OPS Officer: JEFF ROTTON | Notification Date: 02/11/2014 Notification Time: 20:35 [ET] Event Date: 02/11/2014 Event Time: 14:30 [CST] Last Update Date: 02/11/2014 | Emergency Class: NON EMERGENCY 10 CFR Section: 50.72(b)(3)(ii)(B) - UNANALYZED CONDITION 50.72(b)(3)(v)(D) - ACCIDENT MITIGATION | Person (Organization): ROBERT DALEY (R3DO) | Unit | SCRAM Code | RX CRIT | Initial PWR | Initial RX Mode | Current PWR | Current RX Mode | 1 | N | Y | 88 | Power Operation | 88 | Power Operation | Event Text DRYWELL TO TORUS VACUUM BREAKER FAILURE DURING SURVEILLANCE TESTING "While cycling AO-2382A (TORUS-DW VAC BREAKER) for required surveillance testing, [the vacuum breaker] did not indicate fully closed on all available indicators. The procedure for this condition was utilized to continue to cycle the vacuum breaker to achieve closed indication on all available indicators. The vacuum breaker was cycled a total of four (4) times and dual indications were present for approximately six (6) minutes. During the six (6) minutes that the vacuum breaker indications did not show fully closed, the Technical Specification Limiting Condition for Operation (TS LCO) requirement was not met. The Monticello Safety Analysis assumes all eight (B) vacuum breakers are closed, therefore this condition is being reported per 10CFR50.72(b)(3)(ii)(B) and per 10CFR50.72(b){3)(v)(D). The vacuum breakers are all capable of performing their design function and all safety related equipment is operable." The NRC Resident Inspector has been notified. The same vacuum breaker failed its surveillance test in a similar fashion on February 7, 2014 (See EN #49808). The surveillance test for this vacuum breaker is due again on February 18, 2014. | |
