MODULAR SYSTEM FOR SEVERE ACCIDENT ANALYSIS FOR NUCLEAR POWER PLANT

摘要

The present invention relates to a modular system for severe accident analysis for a nuclear power plant, the system comprising: a master module; a first module for interpreting in-vessel phenomena during a severe accident; a second module for interpreting ex-vessel phenomena during the severe accident; and a third module for interpreting fission product behavior during the severe accident by using in-vessel thermal hydraulic information and ex-vessel thermal hydraulic information calculated in the first module and the second module, wherein information transfer among the first module, the second module and the third module is carried out via the master module.
