FAILURE OF SECONDARY CONTAINMENT INTERLOCK MECHANISM

"At 10:19:02 [CST] on November 16, 2013, indication was received in the Control Room that two Secondary Containment doors, in one access opening, were open simultaneously. The interlock mechanism preventing both doors from operating simultaneously did not operate as expected. A worker was staged in the interlock to operate the doors as an interim action while a modification to prevent additional failures was being developed. The worker reported that while opening the reactor building side door the Turbine Building side door opened several inches. Both doors were immediately closed and the interlock was removed from use. Secondary Containment differential pressure remained within Technical Specification required values during the short time both doors were open.

"This condition represents a failure to meet Surveillance Requirement 3.6.4.1.2. As a result, entry into Technical Specification 3.6.4.1 Condition A was made momentarily due to Secondary Containment being inoperable. The doors were secured at 10:19:07 [CST] 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 the safety function.

"The NRC Resident Inspector has been notified."
