池式供热堆厂址设计中的基准地震探讨

小型核反应堆具有较好的安全特性和广泛的应用领域,并获得越来越多的关注。相对于大型核电站而言,外部约束条件对小型堆的推广有很大影响,对需要靠近公众用户的核能供热堆更是如此。该文针对固有安全性较高的池式低温供热堆,论证其能够实际消除明显厂外放射性释放,厂址设计基准地震可以合理优化,作为核能供热设施能够适应我国采暖区大部分厂址条件。

Small nuclear reactors have good safety characteristics and a wide range of applications,and get more and more attention.Compared with large nuclear power plants,external constraints have a great impact on the promotion of small reactors,especially for nuclear heating reactors that need to be close to public users.Aiming at the pool-type low-temperature heating reactor with high inherent safety,this paper demonstrates that it can actually eliminate the obvious release of off-plant radioactivity,and the design benchmark earthquake of the plant site can be reasonably optimized.As a nuclear heating facility,it can adapt to most of the site conditions of heating areas in our country.
