General Electric Mark III pressure suppression containment system analytical model

The analytical models used to simulate the short-term transient response of a Mark III pressure suppression containment to a postulated loss-of-coolant accident are presented. The governing equations are defined together with derivations of the simultaneous differential equations that simulate the transient conditions in the containment. The numerical techniques used to integrate these equations are discussed. All modeling and boundary condition assumptions are described and discussed. Model results are compared with experimental data from the General Electric Company's large-scale Mark III test facility; the comparisons indicate that the model is conservative. This conservatism is reflected in the design parameters that are being specified for those containment systems using the Mark III concept. 11 references
