There are growing interests in decision-making on continued operation of aged nuclear power plants. This paper attempts at identifying factors which may influence on acceptability of public for the continued nuclear power plants. The affecting factors on the decision-making are mainly explored by ID3 algorithm which results are verified through CART and CHAID algorithms. The data were based on a survey of local residents in metropolitan cities. The analysis shows that the vicinity factor have the greatest impact factor on the continued operation of aged nuclear power plants with other factors including respodents’ perception on nuclear, job and income. The resulting factors are then employed for CVM analysis to estimate willingness to pay (WTP) for the continued operation of aged nuclear power plants. The CVM finding is that individual WTP is 570KRW per month in order to secure the continuation of nuclear power.
