  • Energize to actuate engineered safety features actuation system and testing method therefor
    Patent number: 6788213
    Abstract: A component actuation circuit for an engineered safety features actuation system (ESFAS) includes a plurality of coincidence logic contacts, and a plurality of parallel-connected ESFAS component relays. Each of the coincidence logic contacts closes in response to a command signal. The plurality of parallel-connected ESFAS component relays are connected in series between at least two of the plurality of coincidence logic contacts. Closure of at least two of the coincidence logic contacts energizes the parallel-connected ESFAS component relays, thereby energizing a plurality of ESFAS components.
    Type: Grant
    Filed: May 24, 2002
    Date of Patent: September 7, 2004
    Assignee: Westinghouse Electric Company LLC
