Individual plant evaluation uses of MAAP (modular accident analysis program) 3. 0B

OSTI ID:6923095
;
The Modular Accident Analysis Program (MAAP) was developed by Fauske and Associates, Inc., for the Industry Degraded Core Rulemaking Program (IDCOR) as the industry tool for analysis of severe reactor accidents. The MAAP 3.0B is the most recent version of the program available for analysis of severe accidents in boiling water reactors (BWRs) and pressurized water reactors (PWRs). The MAAP is owned by all but a few U.S. utilities and is officially maintained by the Electric Power Research Institute. The MAAP 3.0B contains models for primary system thermal hydraulics, core heatup, fission product release, aerosol and vapor transport, core debris behavior in containment, containment thermal-hydraulic response, and (for PWRs) secondary system behavior. The MAAP 3.0B also contains models for plant systems such as feedwater, auxiliary feedwater, high- and low-head injection and spray systems, residual heat removal heat exchangers, accumulators, fan coolers, and containment sprays. A notable feature of MAAP for IPE uses is its flexible system allowing arbitrary operator actions with these systems in order to simulate realistic accident sequences, including the capability for recovery.
