Deep-Well Injection Modeling of Radioactive and Nonradioactive Wastes from Russian Nuclear Industry Activities, with Examples From The Injection Disposal Sites of SSC RF–NIIAR and CHEPETSK Mechanical Plants

Abstract

Publisher Summary This chapter describes the deep-well injection modeling of radioactive and nonradioactive wastes from Russian nuclear industry activities, with examples from the injection disposal sites of SSC RF-NIIAR and Chepetsk mechanical plants. Reservoir formations at depths ranging from 1100–1450 m have been used for deep-well injection disposal of radioactive liquid wastes from the SCC RF Research Institute of Atomic Reactors (Dimitrovgrad) and nonradioactive industrial wastes from the Chepetsk Mechanical Plant (Glasov). The model for deep injection disposal at Glasov was created by taking into account the analysis of hydrological conditions of the region studied, which includes only one reservoir horizon. Results from mathematical modeling of the underground disposal of liquid waste, carried out at two different sites, have confirmed the feasibility and safety of deep injection disposal of toxic and radioactive wastes into permeable aquifers. These results have been used to justify continuing such disposal of wastes and the development of measures for monitoring such a method.
