Replacement of nuclear power plants has the possibility of affecting the management of electric power suppliers. Therefore, in the nuclear policy, a depreciation method as an equalization method, which means that part of the investment cost is accumulated as an allowance, and after the start of operation, the depreciation cost in the replacement project is equalized, has been introduced in Japan. In this paper, we evaluate the replacement of nuclear power plants by taking into account the uncertainty of operating costs and the depreciation cost in order to examine the effect of the depreciation method on the decision criteria of the replacement. We found that the equalization method is effective for inducing the acceleration of the replacement. Furthermore, we show the relationship between the uncertainty and the depreciation method. It turns out that as uncertainty increases, the difference in investment threshold between the equalization method and the existing depreciation method decreases, and that in option value increases.<br>

わが国における原子力開発利用の歴史はおよそ半世紀になる。この間、わが国における原子力規制はその規制構造を殆ど変えることなく今日にいたっている。このため、現在の原子力規制は合理性・実効性を欠き、信頼醸成を阻害する原子力システムをもたらしている。そこで、本研究では、原子力安全規制に関する知的インフラに関連する論点に焦点をあてて分析を実施し、原子力規制に関する適切なガバナンスを実現するためのフィールドの創出と論点の整理・政策提言を行った。
