This study was to estimate the price of nuclear risk and to explore the acceptability. In this study, The acceptability of nuclear risk was estimated by willingness-to-pay for avoiding nuclear power plant. and In order to review the acceptability, the willingness-to-pay were compared with the actual amount of support. Survey results, In order to avoid the risk of nuclear power plants, the per capita amount payable was 4.283 million won. Calculate over the country, The annual amount is about 5.8719 trillion won. However, the actual funding of the annual was about 0.2046 trillion won. As a result of this study, The funding is lower than the price which is to avoid the risk of nuclear power. and Because of ignoring of people's needs, low responsiveness, non-transparency, and the problems of procedural legitimacy, the acceptability seems to low. As follows, the implications of this study are the three. First, this study was estimated price for the nuclear risk. Second, the actual payment of funds is smaller than the price(Willingness-To-Pay) for avoiding nuclear risk. Third, in spite of a small funding, in order to enhance acceptability of nuclear risk it is necessary to improve the trust.
