摘要： Filtering systems and methods remove debris from coolant in a nuclear reactor setting. One or more filters are installed outside coolant reservoirs specifically where coolant will flow toward the reservoir, such as during a transient or other coolant leak event. Useable filters permit coolant through-flow while catching, straining, diverting, or otherwise removing debris from the coolant without significant interference with the coolant flow.Filters can be installed at any location in a flow path for coolant flowing toward the reservoir, including pipes draining into a suppression pool, floor or personnel platform gratings, areas around main steam legs or steam generators, in a reactor drywell, etc. One or more filters are installed by securing the filter in a coolant flow path into a coolant source. Installation and maintenance can be performed during any maintenance period.

摘要翻译： 过滤系统和方法在核反应堆设置中清除冷却液中的碎屑。 一个或多个过滤器安装在冷却剂储存器的外部，特别是在冷却剂将朝向储存器流动的情况下，例如在过渡或其它冷却剂泄漏事件期间。 可用的过滤器允许冷却剂通过，同时捕获，应变，转向或以其他方式从冷却剂移除碎屑，而不会显着干扰冷却剂流。 过滤器可以安装在用于冷却剂朝向储存器流动的流动路径中的任何位置，包括排入抑制池，地板或人员平台光栅，主蒸汽腿或蒸汽发生器周围的区域，反应器干井等中的管道。一个或 通过将过滤器固定在冷却剂流路中进入冷却剂源中来安装更多的过滤器。 在任何维护期间都可以进行安装和维护。
