TMLB prime -sequence simulation for a VVER-1000-type reactor
During the last decade, extensive work has been performed to calculate the source term behavior for western-type reactors. However, the analysis of severe accidents for VVER-type reactors has just started. To investigate the source term behavior, a number of tools have been developed and tested with success. Among these tools, the Source Term Code Package (STCP) was selected to perform a source term analysis for VVER-type reactors. The input data for this case are based only on typical VVER-1000 features and not on a specific power plant design. For this first approach, no new models were added to the STCP. The selected accident sequence is a transient-initiated event with failure of all makeup to the primary and secondary systems as well as the failure of all active containment safety features (TMLB{prime}). The goal of this work was to investigate the behavior of fission products and aerosols generated during a severe accident in a VVER-1000-type reactor.
