Abstract

Classification of radioactive waste by the degree of its activity is given. Basic requirements to the construction site of radioactive waste repository or burial site are specified. Possible constructive solutions of underground repositories are briefly considered and a detailed description of the spiral structure of RAW repository is given. The influence of temperature and radiation on physical and mechanical properties of concrete and clay is estimated. The character of temperature field distribution around the underground RAW repository in time is obtained. The stress-strain state of the support was evaluated and loads on the support were found under the combined action of temperature and rock pressure, taking into account changes in the physical and mechanical properties of concrete and clay.
