核安全文化对核电厂建设成本的影响分析

Influence of Nuclear Safety Culture on Construction Cost of Nuclear Power Plant

核电由于涉核其建设周期长,加之国内外核安全的严格要求,为此核电厂的建造成本与核安全要求高度正相关。在其建造的过程中,核安全局会按要求严格审查业主、施工单位的各方面,一旦发现与标准不符,监管层有权立即终止核电厂的建造。由于核电的前期成本投入占比大,设备的制造和购买与工期环环相扣,如若中途停工,将对后续的工期造成严重的影响。另外,若核电站建成进入运营期以后发生核安全事故,则属于颠覆性的事故,不仅会带来环境人文问题,还会导致整个厂址废止。因此,核电站从一开始就必须考虑核安全的影响,以及由此带来的经济性问题,尽可能避免潜在危险因素的发生。

Due to the long construction period of nuclear power and the strict requirements of nuclear safety at home and abroad,the construction cost of nuclear power plant is highly positively related to the requirements of nuclear safety.In the process of its construction,the nuclear safety administration will strictly review all aspects of the owners and construction units as required.Once it is found that it is inconsistent with the standards,the regulatory authorities have the right to terminate the construction of the nuclear power plant immediately.At the same time,the initial cost of nuclear power accounts for a large proportion,and the manufacture and purchase of equipment are closely related to the construction period.If the project is stopped halfway,it will have a serious impact on the subsequent construction period.In addition,if a nuclear safety accident occurs after the nuclear power plant is completed and put into operation,it is a subversive accident,which will not only bring about environmental and human problems,but also lead to the abolition of the whole plant site.Therefore,from the beginning,nuclear power plants must consider the impact of nuclear safety and the resulting economic problems,and try to avoid the occurrence of potential risk factors.
