COGAP: a nuclear power plant containment hydrogen control system evaluation code

Creators

Description

The accounting of containment gas concentration following a loss-of-coolant accident is important in the safety evaluation of hydrogen combustible-gas control systems for nuclear power plants. The COGAP code provides such accounting including the effects of (1) the reaction of zirconium and water; (2) radiolysis of core and sump water; (3) corrosion of zinc, aluminum and copper; (4) recirculation between compartments; (5) hydrogen recombiners; (6) purging; (7) nitrogen addition; and (8) atmospheric steam. Controls are available to determine when options are initiated; for example, the hydrogen recombiner can be started when the hydrogen concentration reaches a user-specified value
