【西德《原子经济》1983年第1期第28页报道】最近关于用先进压水堆代替现有压水堆的谈论很多。这方面的基水设想是,通过慢化剂的减少,使能谱变硬,把转换比提高到0.9—0.95。在这种情况下,现有压水堆的 V_m/V_F=2,而先进压水堆的 V_m/V_F=O.5(这里 V_m 指慢化剂的体积,V_F 指反应堆燃料的体积。——编者注)。人们认为,先进压水堆是容易实现并得到批准的。对于供电企业来说,一定会提出这样的问题,即与现有压水堆相比,先进压水堆的发电成本能降低多少。实际感兴趣的
[West Atomic Economy, 1st Issue, 1983, p. 28] Recently there has been much talk about the replacement of existing pressurized water reactors with advanced pressurized water reactors. The base water concept in this regard is that by reducing the moderator, the energy spectrum becomes harder and the conversion ratio is raised to 0.9-0.95. In this case, the existing PWR has V_m/V_F=2, while the advanced PWR has V_m/V_F=O.5 (where V_m refers to the moderator volume and V_F refers to the reactor fuel volume. Editor’s Note). People believe that advanced PWRs are easy to implement and approved. For power supply companies, the question will surely be raised as to how much the cost of power generation for advanced PWRs can be reduced compared to existing pressurized water reactors.
