Feasibility Study on the Elimination of Separators in Small Simplified BWR(SSBWR-200)

结合小型简化沸水堆SSBWR-200的设计方案,对小型沸水堆取消汽水分离器方案的可行性进行了较为详细的分析。通过对干燥器性能和汽水自然分离现象的研究发现,仅依靠自然分离和干燥器,便可以将蒸汽湿度降低至1wt%。

Feasibility of eliminating separators in SSBWR-200 ,which is a new kind of small simplified BWR, is studied. According to the capability of natural separation and dryers, the humidity of steam out of reactor without separators can be decreased to 1wt% just by means of natural separation and dryers, which meets the demand on the quality of steam into the turbine. It is concluded that the scheme of eliminating separators in SSBWR-200 is feasible and the stability of reactor is also improved by this simplification.
