"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.

"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)."
