Title	Both Secondary Containment Access Doors Opened Simultaneously
Event Description	At 16:55:59 [CDT] on September 23, 2013, indication was received in the Control Room that two Secondary Containment doors, in one access opening, were opened simultaneously. The interlock mechanism preventing both doors from operating simultaneously did not operate as expected. This condition represents a failure to meet Surveillance Requirement 3.6.4.1.2. As a result, entry into Technical Specifications 3.6.4.1 condition A was made due to Secondary Containment being inoperable. The doors were secured at 16:56:04 and Secondary Containment was declared operable. This event is being reported in accordance with 10 CFR 50.72(b)(3)(v)(C) as a condition that could have prevented the fulfillment of a safety function. The NRC Resident Inspector has been notified.
