### Abstract

disposal. This technology involves the maximum use of waste processing equipment, which is already available at NPP sites, by processing all already accumulated and formed in the future evaporator bottoms to the state of salt melt. As a result, a package for radwaste disposal will be formed as a part of a protective container, four KRO-200 containers with salt melt with void-filled geopolymer, which is quite acceptable in terms of radiation protection properties.

Keywords: radioactive waste, evaporator bottoms, salt melt, conditioning, specific formation.
