Description

technical field

[0001] The invention belongs to the field of radioactive waste treatment, and relates to a treatment device for various radioactive wastes, in particular to absorbent paper, wet rags, plastic cloth, cotton products, waste wood and technological processes produced in nuclear industry and nuclear power plant nuclear reactor processes A variety of solid radioactive waste treatment devices such as waste resins generated in the Background technique

[0002] As an efficient and clean energy, nuclear power has been increasingly valued and utilized by people. As of 2010, there were 13 nuclear power units in operation in mainland my country, and 24 units under construction will also be put into commercial operation successively. While nuclear power brings huge economic benefits to people, the technological waste and technical waste produced in the working process have certain radioactivity. For example, in addition to producing technological waste concentrate, sludge ...
