Description
Nuclear cycle facilities in Russian Federation by now has accumulated (and continue accumulating) a large amount of radioactive wastes, which contains different subjects with the complex morphology and various nuclide set [1, 2]. The only way to solve the problem of the long-term radioactive wastes storage and complying all the up-to-date safety requirements is to create the modern repository as a capital construction. There are no repositories of the sufficient capacity and environmental stability created by ROSATOM being operated yet. In fact, it means that all the design work and engineering surveys have still to be executed.
The article discusses the basic design of the repository for the radioactive wastes class 3 and 4 in terms of justification of investments (JOI) is going to be realized at the Production Association «MAYAK».
The variants of this basic design project providing the economic efficiency of the radioactive wastes management, based on the repository plant geological and ecological features [3-5] are considered.
Such a repository concept is proposed to perform two main functions:
1) safe storage of the solid radioactive wastes of low and medium volume activity with industrial quantities provided by the utility systems (passive or active);
2) exception of the radionuclide migration through the protecting barriers provided by the localization constructions of the repository building.
