地下核电厂经济性分析

Economic Analysis of Underground Nuclear Power Plants

经济性是否合理是地下核电厂是否值得建设的重要因素。通常认为增加地下工程的费用导致地下核电厂的经济性比地面核电厂差;然而,地下核电厂的概念设计结果表明:与同等规模同等堆型的地面核电厂相比,地下核电厂的静态投资增加幅度小于12%,在可接受的范围内。考虑到地下核电厂采用封固埋葬的退役方式成本仅为立即拆除的30%、核安保所需的人数和经费小于地面核电厂,具备取消应急计划区的可能性,地下核电厂的综合经济性优于地面核电厂。

Economy is an important factor for the construction of underground nuclear power plants. It is usually considered that the cost of underground engineering is worse than that of the nuclear power plant. But the conceptual design of the underground nuclear power plant shows that the addition static investment of the underground nuclear power plant is less than 12% compared to the same size and same reactor type nuclear power plant on the ground, which is in the acceptable range. Since the cost for the decommission of the underground nuclear power plant by burring is only 30% of the immediate decommissioning, less people and cost for the nuclear security is required comparing with ground nuclear power plant, and it is possible to eliminate the contingency plan area, the overall economy of the underground nuclear power plant is better than that of the ground nuclear power plant.
