中国核电

钠冷快堆是第四代核能系统论坛(GIF)提出的六种堆型之一，也是世界上运行堆年最长的第四代堆型。钠冷快堆具有增殖和嬗变的功能，能有效解决核能可持续发展问题。中国实验快堆工程已于2011年建成投运，在此基础上研发的示范快堆项目已开工建设。当前，制约快堆工程发展的问题是经济性问题。本文根据钠冷快堆技术特点及其在核电体系中的作用，研究了不同燃料循环模式下，快堆及其闭式燃料循环的经济评价模型及方法。

The sodium cooled fast reactor is one of the six reactor types proposed by GIF's fourth generation nuclear power system, and it is also the fourth generation reactor type with the longest operating year in the world. Sodium cooled fast reactors have breeder and transmutation functions, which can effectively solve the problem of sustainable nuclear energy development. The China Experimental Fast Reactor project was completed and put into operation in 2011, and the construction of the demonstration fast reactor project developed on this basis has started. At present, the problem that restricts the development of fast reactor engineering is the issue of economic efficiency. This article studies the economic evaluation model and method applicable to sodium cooled fast reactors and their closed fuel cycles based on the characteristics of sodium cooled fast reactor technology and its role in the nuclear power system.
