ENS 482652 September 2012 08:35:00As 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 Oconee Nuclear Station, the EOF would be set up in the Catawba Alternate Technical Support Center (TSC) location. This facility is used as a backup location for the Catawba 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 notified the South Carolina Department of Health and Environmental Control, Pickens County, and Oconee County. The licensee has notified the NRC Resident Inspector.

This is a non-emergency report. No actual event has occurred. At 2230 hours EDT, on September 01, 2012, Oconee Nuclear Station Operations determined that the radiation monitor for Low Gas Unit Vent monitoring failed its check source and was declared inoperable. This monitor is used for determination of Emergency Action Levels (EALs) in ALL Modes. Specifically, the criterion states that an Unusual Event should be declared if this radiation monitoring reading reaches 9.35E5 for greater than 60 minutes. This condition was discovered during weekly radiation monitor setpoint determinations.

There is no adverse impact on nuclear safety. A redundant method for sampling and determination of activity levels has been implemented per SLC 16.11.3. The same EAL criterion has a redundant determination of Unusual Event classification based on these activity levels. This report is submitted based upon a loss of emergency assessment capability in accordance with 50.72(b)(3)(xiii). The NRC Resident Inspector has been informed.
