Title	Loss of Containment Smoke Detection Capability
Event Description	At 1454 CST on December 16, 2013, the Unit 1 pyro panel (smoke detection panel) was declared non-functional due to an unexpected failure. Viable compensatory measures have been established for all affected areas except the Unit 1 Containment Building. Since a fire in Containment is an entry condition for the site's Emergency Plan, this is considered a loss of emergency assessment capability and is being reported per 10CFR50.72(b)(3)(xiii). Containment temperatures are being monitored while the pyro panel is out of service, however, this is not considered a satisfactory compensatory measure for maintaining effective assessment capability. The NRC Resident Inspector has been notified. * * UPDATE AT 2046 EST ON 12/17/13 FROM DARRIN GARD TO DANIEL MILLS * * * The Unit 1 pyro panel has been returned to service as of 1554 CST on 12/17/13, which restores Unit 1 containment fire detection capability. The NRC Resident Inspector has been notified. Notified R2DO (Freeman).
