In Kazakhstan there are all conditions for the organization of the complete technological cycle of nuclear power generation, from extraction of uranium ores and ending with facilities for long-term storage of radioactive waste. In the Republic there have been no works yet on such an important component of this cycle as creation of underground RW disposal facilities, where the subject of separate investigation is an underground research laboratory (URL) for confirmation of the long-term safe disposal of RW in the selected location of the underground disposal facility. There for e during implementation of this project it is planned to use experience of the countries, where URL were designed, built and operated before creation of RW disposal sites. Such countries include Sweden, Finland, Japan, Russia, China, Belgium, India, Switzerland, etc., where there are extensive areas of crystalline rock development, and where deep RW disposal is recognized at the legislative level. The countries operating such facilities have proven technologies and experience in development, construction of URL and RW isolation sites.
