<P>PROBLEM TO BE SOLVED: To provide a nuclide separation processing method and a system allowing easy operation and for further improving removal of nuclides. Ž<P>SOLUTION: An iron cosedimentation of Co, Ni, etc. is produced by introducing an iron ion into a waste liquid treated with high-temperature and high-pressure water of an ion exchange resin used for a reactor water cleanup system and controlling pH, and a magnetic powder is introduced in order to add a coprecipitating ability to the cosedimentation. Then a supernatant and the cosedimentation are subjected to solid-liquid separation. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
