| Event Description | At 0426 hours0.00493 days <br />0.118 hours <br />7.043651e-4 weeks <br />1.62093e-4 months <br /> on 11/22/06, with the reactor critical and attempting to bring the Main Turbine on-line and shifting from Emergency Feedwater to Main Feedwater, 'B' Steam Generator level increased to the Hi-Hi level (P14) trip set point, resulting in tripping all 3 Main Feed Water Pumps. The reactor did not trip.
All systems functioned as designed and the plant was stabilized. The NRC Resident Inspector was notified of this event by the licensee. |
