Abstract
An injection and solidification operation as well as a kneading and solidification operation can be performed by a single facility. A decreased amount of radioactive secondary waste is generated. A solidifying agent paste is prepared by kneading a solidifying agent and additive water. The solidifying agent paste is injected into a solidifying container. The radioactive waste is charged into the solidifying container and kneaded.
Claims6
A process of treating radioactive waste, comprising:
- transferring a solidifying container to a first location of a radioactive waste treatment facility along a transferring line;
- preparing a solidifying agent paste by kneading a solidifying agent and an additive water and injecting the solidifying agent paste into the solidifying container at the first location;
- transferring the solidifying container to a second location downstream of the first location with respect to a process flow;
- and
- introducing radioactive waste into the solidifying container and kneading the radioactive waste and the solidifying agent paste in the solidifying container at the second location.
