Principles of and experience in low level, medium level and TRU element bearing radioactive waste treatment

The treatment of low and medium level liquid and solid wastes, of off-gas and exhaust air, of TRU wastes, and the conditioning of low and medium level liquid waste concentrates, as used in the Nuclear Research Center of Karlsruhe, are described. The transport of low level solid and liquid wastes is done by trucks with concrete and steel containers. The interim storage of low and medium level solid wastes is carried out in simple store houses with a decontaminable floor or buildings with shielded walls and remote handling devices. (DG)
