重水反应堆采用过滤和离子交换法旁通回路连续净化重水。为提高运行寿命,减少强放操作次数,对过滤器设计进行了改进。新型过滤器为一带法兰的圆锥体,内有两个相套的网架,在内网架内、外侧和外网架的内侧,衬有不锈钢网,网架间夹层内,装满粒状过滤介质——失效树脂和石英砂。法兰采用活节螺钉连接,真空橡皮密封。网架置于 The heavy water reactor adopts the filtration and ion exchange method by-pass loop to continuously purify the heavy water. In order to improve the running life and reduce the number of forced operation, the filter design has been improved. The new filter is a flange with a cone, which has two sets of network frame, inside the grid, outside and inside the outer grid, lined with stainless steel mesh, interlayer between the sandwich, filled with granular filtration Medium - Failure resin and quartz sand. Flange with flexible screw connection, vacuum rubber seal. Grid placed
