Since the accident that happened in The Fukushima Daiichi Nuclear Power Station, a scattered radiological decontamination and decommissioning technology are attracting a lot of attention. The removal of radioactive crud in the nuclear power plant will become one of the more important elemental technologies of the decommissioning from now on. However, the effective technique to remove the crud which is applicable at high-temperature area around the nuclear power plant does not exist. Therefore, we focused on the magnetic property of the target cruds which are paramagnetic substance and high gradient magnetic separation (HGMS) was proposed as a nuclear power plant crud removal method. In this study, we tested the magnetic separation of crud sample model in room temperature for the practical use of the HGMS device and a possibility of the application of our method was indicated.
