The Reactor Water Cleanup (RWCU) is the filtration system for the reactor vessel. (Its kinda like a pool filter) Its primary safety function is to isolate if needed. Filtering is not needed for safe shutdown but it is good to keep clean water in the vessel to avoid contaminates that may become radioactive or mitigating corrosion on various components.
