Application of concrete to treatment and disposal of radioactive wastes

The radioactive waste is disposed safely at the underground and so on, after treatment and storage in the nuclear power facility. During treatment, storage and disposal of radioactive waste, the concrete is used and will be used for various purposes. This paper presents the states of the application of concrete to treatment, storage and disposal of the radioactive waste and the spent fuel from the nuclear power plant. In the chapter of the 1st and the 2nd, it is described what kind, how about and how many the radioactive wastes are. In the chapter from the 3rd to the 5th, it is described the requisites for the concrete material and application of concrete to the management of radioactive waste. Those are the solidification material, the material for the container in the treatment, the radiation shielding wall material in the storage facility and material for the construction of the disposal facility and the water stop structure at the disposal site and so on.
