英文摘要	Decontamination is a necessary and effective way of radioactive contamination reduction in the IVC (In-Vessel Component) maintenance and decommissioning process for CFETR. Plasma unstable events that occur in the reactor produces a large amount of tritium dust in the vacuum vessel. Decontamination also plays an extremely important role in reducing the radioactive pollutants diffusion, cumulative radiation dose and staff occupational exposure level, controlling radioactive effluent of nuclear facilities and enhancing remote handling equipment life and reliability and even series environmental protection problems. In this study, we carry out selection and analysis of decontaminate method for CFETR hot cell, comparing to existing mature cleaning and decontamination methods for radioactive contaminated surface, with the comprehensive consideration of the characteristics of PFC (Plasma Facing Component) pollution and the limitation of hot cell remote handling operation, analyze the adaptability and requirements of the fusion facility, selecting the most suitable cleaning method satisfied with necessary requirements for CFETR hot cell. Establishment of PFC (Plasma Facing Component) decontamination method evaluation system provides technical support for the design of hot cell remote handling cleaning device.
