Title | Loss of Control Room Hvac |
Event Description | At 2251 EDT on 8/21/2016, the 'A' Train of Control Room ventilation was inoperable for scheduled testing and the 'B' Train of Control Room ventilation was declared inoperable due to a thermal overload of a cooling fan. This resulted in not meeting the limiting condition for operation in accordance with Technical Specification 3.7.6. No action statement exists for having two trains of Control Room Ventilation inoperable and Technical Specification 3.0.3 was applied. At 2255 on 8/21/2016 the 'A' Train of Control Room Ventilation was declared operable and Technical Specification 3.0.3 was exited.
The licensee notified the NRC Resident Inspector.
Event notification 52192 is being retracted. Upon further evaluation, Harris determined that the 'A' train of Control Room Emergency Filtration was Operable at the time 'B' train became Inoperable. Therefore, there was no loss of safety function. The NRC Resident Inspector has been informed of this retraction. Notified R2DO (Rose). |
