The safety treatment of radioactive components has become one of the key issues to achieve the sustainable development of nuclear energy.Generally,the technology used for the removal of loose pollutants has poor decontamination effect on equipment gaps and dead corners.In the nuclear emergency,it is difficult to meet the requirements of fast fixing,shielding and decontamination of surface pollutants.In order to solve these problems,it is necessary to develop a new decontamination technology.Foam gel was prepared by self-made base material,adding a certain amount of foaming agent and crosslinking agent,and its decontamination performance was evaluated.The foam gel had good decontamination capability for simulated stainless steel contaminated samples,contamination samples with voids or pores and the ground.Different cleaning processes can be selected according to different operation requirements.The foam gel can be dried to form a membrane,achieving two wastes minimization,making it possible to become a new material for removing loose surface pollution on nuclear facilities.
