研究了两种燃料(低浓铀不加钍和高浓铀加钍)的高温气冷堆燃料循环。在30年中共投入40座1000MWe的高温气冷堆,对燃料进行后处理的循环、一次通过循环以及压水堆的燃料循环进行了比较,计算结果如下:一次通过循环和后处理循环相比在经济上便宜3～7％,在资源上多消耗天然铀～16％,天然钍～50％,如果同时考虑经济和资源则后处理循环明显优于一次通过循环,和压水堆循环相比则高温气冷堆在经济和资源节省两方面都优于压水堆。
The high temperature gas cooled reactor fuel cycle of two fuels (LEU without thorium and HEU plus thorium) was studied. In the past 30 years, 40 high temperature gas cooled reactors of 1,000 MWe were put into operation. The fuel post-treatment cycle, once-through cycle and PWR fuel cycle were compared. The calculation results are as follows: Compared with the post-treatment cycle Economically cheaper 3 ~ 7%, more resources in natural uranium consumption of ~ 16%, natural thorium ~ 50%, if both economic and resource considerations post-treatment cycle was significantly better than once through the cycle, compared with pressurized water reactor cycle High-temperature gas-cooled reactor is superior to PWR in terms of economy and resource saving.
