System for Assessing of Emergency Planning Zone in Nuclear Power Plant using probabilistic safety assessment result

摘要

The present invention relates to a radiation emergency planning zone evaluation system of a nuclear power plant using a stochastic safety analysis result, and more particularly, to a reactor core inventory information collecting apparatus for collecting information on a core stock quantity which can be changed when a nuclear power plant is operated; A probabilistic safety analysis system that performs real - time risk analysis by reflecting various changes that may occur in the operation of a nuclear power plant; A meteorological data collecting device for collecting meteorological data observed at a specific time interval in a nuclear power plant; A population data collecting device for collecting data related to the distribution of the population within a radius of 1 km to 80 km based on the nuclear power plant at specific time intervals; Based on the information collected through the core stock information collecting device, the stochastic safety analyzing device, the weather data collecting device and the population data collecting device, the average external system dose and the average child pediatric thyroid equivalent dose reach the reference dose An alienation analysis device for extracting each lot; (EPZ) evaluated according to the analysis result of the marginal analysis apparatus and the actual radiation emergency planning zone (EPZ), and calculates the effectiveness evaluation value (EER) , A validity evaluating device for judging validity in accordance with the calculated evaluation value; .
