Nuclear power project is one of clean energy in coastal areas, it's investment decisions are affected by a variety of uncertainties. This paper proposes a real option decision model. The model considers the investment cost of nuclear power projects, project fixed costs, on-grid electricity prices and carbon dioxide prices. The market linkage is added to the model, considering the value of nuclear power investment under market linkage, modeling and analyzing the value of nuclear investment in enterprises. The accuracy and effectiveness of the model are verified by scenario analysis. The results of the study show that the nuclear power plant under the option is the most valuable when considering carbon dioxide trading. When considering carbon dioxide trading, the abandoned path is as high as 25.99%. Considering carbon dioxide trading can avoid mistakes in investment decisions, and it is beneficial for companies to make correct decisions when investing in nuclear power projects. The research results provide a certain reference for investment decisions in energy projects.
