Title | Technical Specification Required Shutdown Due to Inoperable Control Room Chiller Train |
Event Description | 'B' Train Control Room Chiller inoperable due to being aligned to Unit 1 Nuclear Cooling Water Train 'B.' This is a normal alignment for Unit 1 ESF 'B' Train testing. When we attempted to start 'A' Train Control Room Chiller, it failed to start. This placed Unit 2 in Tech Spec 3.0.3 at 0320 on 10/08/05. Unit load reduction started at 0720 on 10/08/05.
The licensee stated that the load reduction was terminated at 0815 on 10/08/05 based on a Notification of Enforcement Discretion (NOED) granting a 24-hour extension. The licensee notified the NRC Resident Inspector. |
