A cartridge-type filter has easily exchangeable and safe distance handling filter cartridges contaminated with radiation-emitting contaminants. The filter includes a filter housing having an inner annular shoulder forming a valve seat, and a filter cartridge has an outer ring in sealing engagement with the shoulder for both supporting the cartridge and dividing the filter housing into two separate chambers respectively in communication with the supply and return conduits provided on the housing. A portion of the reactor cooling water is conducted continuously through the filter circuit which is parallel to the main water flow.
