EMERGENCY OPERATIONS FACILITY NOT AVAILABLE
"On 4-22-13, at 1623 [CDT], the ANO Unit 2 control room was notified of a loss of ventilation capability to the Emergency Operations Facility (EOF). The main control boards associated with the variable speed drives on both air handling units at the EOF have failed. Therefore, there are no means to filter air for the EOF. If the EOF is staffed, the EOF will be required to relocate to the Alternate EOF in the event of a release that causes the EOF evacuation criteria to be exceeded, as directed by approved emergency response procedures.
"The on-site Operations Support Center, on-site Technical Support Center and off-site Alternate EOF remain fully functional to perform emergency assessment activities. Efforts are underway to expedite repairs.
"This notification is required by 10CFR50.72(b)(3)(xiii)."
The licensee has notified the NRC Resident Inspector.
* * * UPDATE ON 4/24/13 AT 1003 EDT FROM STEVE COFFMAN TO DONG PARK * * *
At 1637 EDT on 4/23/13, the EOF ventilation has been restored and the EOF has full functionality.
The licensee has notified the NRC Resident Inspector.

AGREEMENT STATE REPORT - SHUTTERS FOUND THAT WERE DIFFICULT TO OPERATE ON TWO PROCESS GAUGES
The following was received from the State of Louisiana via facsimile:
"On 4/22/2013, the Radiation Safety Officer (RSO) for ExxonMobile Chemical was performing his annual inventory and operational checks on the level gauges at the Baton Rouge facility. During the checks, two level gauges were found with shutters that were difficult to operate.
"The gauges detected were Ronan Engineering Gauges, devices involved, Model Number SAF-F37. One gauge is S/N 0781GK loaded with 100 mCi of Cs-137 and S/N 4585GH loaded with 25 mCi of Cs-137. Ronan Engineering has been contacted to fix the problem or repair the gauge. These gauges are installed on process and pose no safety threat to the general public or the employees. This is not considered a safety equipment failure, just being installed on a process in a very harsh corrosive environment.
"This is a two shutter malfunction on level gauges installed on processes. These devices do not pose a radiation exposure threat to the general public. They will remain in operation on the process until and after repair.
"The department considers this event closed."

EMERGENCY OPERATIONS FACILITY NOT AVAILABLE
"The Comanche Peak Nuclear Power Plant Emergency Operations Facility (EOF) is not available due to the loss of HVAC and filtering capabilities resulting from a failed Emergency Operations Facility (EOF) ventilation fan. The condition was discovered at 0900 CDT on 4/22/13. Repair parts are expected by the morning of 4/23/13 and the EOF is projected to be available by the end of the day on 4/23/13.
"Compensatory measures are in place to staff and activate the Alternate EOF in the event of a declared emergency.
"The NRC Resident Inspector has been informed."
