Similar Events
In March of 2011, Seabrook personnel identified that feedwater isolation on hi-hi steam generator level was not being adequately tested as required by TS 4.3.2.2, which resulted in declaration of a missed surveillance.
LER 2012-001, Inadequate Testing of Certain Emergency Feedwater Actuation System Relays, reported that response time for starting and loading of the motor-driven emergency feedwater pump had not been adequately tested.
