"Between December 6, 2011 and January 13, 2012, a sequence of activities are planned that will render the Technical Support Center (TSC) non-functional at times by removing the emergency ventilation system from service. These activities are being performed in support of planned preventive maintenance and extended power uprate facility upgrades. In preparation for these emergency ventilation system outages, the TSC emergency responders were notified that if an emergency occurred during these outages the Emergency Coordinator and the TSC staff involved with classification, notification and PARS should report to the control room. All other TSC personnel should report to the Operational Support Center. The duration for each of these TSC outages is expected to be less than 24 hours. The NRC Operations Center will be provided an update to this notification when the TSC emergency ventilation has been removed from service and following restoration for each time period. This 8 hour notification in accordance with 10 CFR 50.72(b)(3)(xiii)."
The licensee notified the NRC Resident Inspector, and State and local governments.

"A degraded fire barrier between Fire Area (FA) 118 (Bus 26 Room) and FA 128 (Bus 27 Room) has existed during the last three years. The top of the wall between the Bus 26 and Bus 27 room had a missing/degraded fire barrier. At the time of discovery on December 9, 2011 a fire watch was in place. However, it was determined that at various times during the last three years a fire watch was not established.
"Bus 27 has been conservatively aligned to Bus 26 to provide the required degree of separation for redundant safe shutdown trains (between Bus 26 and Bus 25). The fire watch will remain in place as a compensatory measure until the fire barrier is repaired.
"[The] NRC Resident [Inspector] has been informed." | |
