The MAAP 3.0B code is a coupled thermal-hydraulics and fission product release and transport code for prediction of boiling water reactor and pressurized water reactor (PWR) responses to severe reactor accidents. MAAP 3.0B is maintained by the Electric Power Research Institute to assist in utility performance of IPEs (individual plant evaluations) and other source term calculations. Significant improvements have been made to MAAP 3.0B during 1989, including methods of interest for other code developers. Three improvements are selected for this discussion: (1) a model for flammability and combustion of possible gas mixtures, (2) a model for natural circulation intercompartmental flow including countercurrent flows, and (3) integration diagnostics and control.
