To improve the current deterministic regulation of nuclear power plant risk, the numerical guide lines for the probabilistic regulation are proposed by using the limit line approach which includes risk aversion concept. Approaches to the regulation of risk from nuclear power plants in which potential accidents may result in a broad range of adverse consequences must take into account several different aspects of risk. These include overall or average risk, risk aversion, and the impact of low consequence-high frequency accidents.
The purpose of this study is to set limit lines for the nuclear power plant risks which meet all the requirements for the regulatory tool and to give the acceptable risk level for the individual and public radiation risk and utility financial risk.
This study is composed of proposals for individual fatality, public fatality, I-131 & Xe-133 release, and the financial risk limit lines, as form of Complementary Cummulative Distribution Function.
Another important result of this study is the proposal for cost-effectiveness criterion including risk aversion concept to improve the weak point of current cost-benefit guide line.
Numerical examples are shown in the figure or tables to illustrate the way in which an assessment to acceptable limit line could be possible.
현재 사용되고 있는 원자로 위험도에 대한 결정론적인 규제방법을 보완하기 위하여, 한계선을 이용한 확률론적인 규제의 방법을 제시하였다.
이 연구에선 원자로 사고에 의한 개인의 위험도, 대중의 위험도, 전력생산자의 재정적인 위험도에 대한 허용한계선을 두었다. 또한 안정성을 위한 투자의 효과성을 측정하기 위한 방법을 제시하였다.
본 연구에선, 수치적인 예가 확률보조누적함수의 형태로 나타나 있다.
