| ENS 50522 | 9 October 2014 11:30:00 | A non-license supervisor has been found in violation of the Duke Energy Fitness for Duty Policy. The individual's access to the plant has been suspended. The NRC Resident Inspector has been informed. The licensee will be notifying State and Local authorities. |
| ENS 49990 | 2 April 2014 21:08:00 | This is a non-emergency notification. As part of converting to NFPA (National Fire Protection Association) 805, Catawba determined that there are conditions that may not ensure required equipment remains available under certain postulated fire scenarios. The determination concluded that the effects of a postulated fire in specific fire areas could prevent critical systems or components from performing their intended functions, potentially resulting in the inability to achieve and maintain safe shutdown. Affected fire areas are as follows (elevation numbers are in parentheses): 1. Residual Heat Removal/Containment Spray Pump Room (522) 2. Unit 2 Auxiliary Feedwater Pump Room (543) 3. Unit 1 Auxiliary Feedwater Pump Room (543) 4. Auxiliary Building Common Area (543) 5. Unit 2 Electrical Penetration Room (560) 6. Unit 1 Electrical Penetration Room (560) 7. 2ETB Switchgear Room (560) 8. 1ETB Switchgear Room (560) 9. Unit 2 Battery Room (554) 10. Unit 1 Battery Room (554) 11. Auxiliary Building Common Area (560) 14. Unit 2 ETA Switchgear Room (577) 15. Unit 1 ETA Switchgear Room (577) 17. Unit 1 Cable Room (574) 18. Auxiliary Building Common Area (577) 20. Unit 1 Electrical Penetration Room (594) 45. Unit 1 Cable Room Corridor (574) 46. Unit 2 Cable Room Corridor (574) 48. Unit 2 Inside Doghouse 49. Unit 1 Inside Doghouse RB1. Unit 1 Reactor Building RB2. Unit 2 Reactor Building This is reportable as an unanalyzed condition that significantly degrades plant safety in accordance with 10 CFR 50.72(b)(3)(ii)(B). Fire watches have been implemented as appropriate in response to this determination. This condition has been entered into the Catawba Corrective Action Program. The NRC Resident Inspector will be notified. The licensee will notify the State of North Carolina and South Carolina and well as the local counties. |
| ENS 49319 | 4 September 2013 04:13:00 | This is a non-emergency eight hour notification for a loss of Emergency Assessment Capability. This event is reportable in accordance with 10CFR50.72(b)(3)(xiii) because the work activity affects the functionality of an emergency response facility. Planned maintenance activities are being performed on 09/04/13 to the Technical Support Center (TSC) HVAC. The work includes performance of planned outside air intake valve electrical repair. The planned work activity duration is approximately 12 hours. If an emergency is declared requiring TSC activation during this period, the TSC will be staffed and activated using existing emergency planning procedures unless the TSC becomes uninhabitable due to ambient temperature, radiological, or other conditions. If relocation of the TSC becomes necessary, the Emergency Director will relocate the TSC staff to an alternate location in accordance with applicable site procedures. The Emergency Response Organization team has been notified of the maintenance and the possible need to relocate during an emergency. The NRC Resident Inspector has been notified. This event poses no threat to the public or station employees. |
| ENS 49036 | 15 May 2013 15:00:00 | This is a non-emergency 30 day notification for missing licensed material. This event is reportable in accordance with 10CFR20.2201(a)(1)(ii). On April 16, 2013, while performing the required semi-annual source leak check and inventory, Radiation Protection personnel could not locate the source label tag or cable for source RMC-0169 on radiation monitor 1EMF44H (This monitor has not been in use since 1995). The monitor's pre-amplifier box had been removed as well. 1EMH44H was inspected and the source was not found within the housing. A search was conducted for this missing source, however it could not be located. During the previous source leak check and inventory on October 4, 2012, the source was in its expected location. Source RMC-0169 is a 200 milligram depleted uranium source. The total original activity of the source was 9.998E-02 microCuries (3.03E-02 micro curies; U-234; 1.98E-03 microCuries; U-235, 6.77E-02 microCuries; U-238). The reportable limit for U-234 (the shortest-lived isotope in the source is U-234 with a half-live of 2.46E+05 years) is 0.01 microCuries per 10CFR20, Appendix C. Based on the activity of U-234 present in the source of 0.03 microCuries, this 30 day phone notification to the NRC is being provided pursuant to 10CFR22.2201(a)(1)(ii). The external dose to an individual from this source is negligible due to the small quantity and the type of material involved. Therefore, this event has no adverse effect upon the health and safety of employees or the public. The required written report pursuant to 10CFR20.2201(b)(1) will be provided to the NRC within 30 days of the telephone notification. The NRC Resident Inspector has been notified. The licensee with notify State and local authorities. THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks.

| ENS 48267 | 2 September 2012 09:21:00 | As part of preparation for the upcoming Democratic National Convention (DNC), contingencies are in place associated with the common Emergency Operations Facility (EOF) for Catawba, McGuire, and Oconee Nuclear Stations. The common EOF is located in Charlotte, NC. Because of the potential for event security to delay staffing of the facility within the prescribed time frame, Duke Energy is implementing its business continuity plan for the EOF during the period from 12:00 PM (noon) on September 2nd until 24:00 (midnight) on September 6th. If a declared emergency were to occur at Catawba Nuclear Station, the EOF would be set up in the McGuire Alternate Technical Support Center (TSC) location. This facility is used as a backup location for the McGuire TSC as specified in station procedures. This report is being made in accordance with 10CFR50.72, criterion (b)(3)(xiii), and in accordance with NUREG-1022, Revision 2, as a condition that may impair the functionality of an Emergency Response Facility. The licensee will notify the State of North Carolina, State of South Carolina, York County, Gaston County, and Mecklenburg County. The licensee has notified the NRC Resident Inspector. |
