[3F06] Study for considering the Level 3 PRA results in time series

*Ryohei Ichikawa1 (1. NRA)

Keywords:Level 3 PRA, WinMACCS, Dose evaluation

In the conventional Level 3 PRA, the consequences, such as dose and health effect occurrence probability, on the assessed objects based on the distance category and protective measure settings are presented as integrated values for the calculation period. The integrated values does not provide information on the timing of the magnitude of consequences. In order to identify the timing of the consequence and consider effective countermeasures in terms of risk, the method of analyzing the consequence over the time series of the calculation period was studied.
