Development of Simulation and Visualization System for Understanding the Physical Phenomena of Accident Sequences in PSA

摘要

This paper presents a framework in which, accident sequences are obtained by a dynamical event tree/GO-FLOW combination, and a specific accident sequence is expressed visually using a plant simulator and visualization system, along with accident progress. An advanced marine reactor: MRX is taken up, and thermohydrodynamic behavior is calculated by the MARCH2 code. With the completion ofthis system, it is overcome the difficulty in comprehending the analysis results of PSA.
