Loss of Offsite Power and Subsequent Press ReleaseOn Sunday, February 10, 2013 at 1405 (EST), with the reactor at 0% core thermal power, all control rods fully inserted, and in cold shutdown conditions, the plant experienced a loss of off-site power. With Pilgrim Station aligned to off-site power via the start-up transformer (SUT), a fault on the 'B' phase of the SUT was experienced due to suspected falling ice striking the phase's insulator. This resulted in the tripping of the feeder breaker, ACB-102, and the loss of power to 4160 KV buses A1 through A4. Emergency Diesel Generators (EDGs) 'A' and 'B' auto-started as designed and are powering emergency buses. The loss of off-site power resulted in de-energization of both Reactor Protection System (RPS) channels resulting in a reactor scram signal and isolation of shutdown cooling. At 1418, shutdown cooling was returned to service. All other plant systems responded as designed. Station personnel are in the process of establishing back-up power in accordance with plant procedures. The following press release was made at 1715 hours: 'Offsite power to Pilgrim station was interrupted this afternoon.
