MATERIALS AND TECHNOLOGIES PROVIDING RADICAL IMPROVEMENT OF RW STORAGE FACILITY WATERPROOFING CAPACITIES.

The article explores the application of modern clay mineral-based materials and technologies for the development and restoration of engineered safety barriers at the facilities holding non-retrievable radioactive waste during their upgrading to a long-term safe storage configuration (term referred to as conservation in Russian literature) and to disposal facilities. It presents the fields of application, available experience of such applications and the main characteristics allowing to expand the practice of their application at nuclear facilities.

Keywords: radioactive waste, bentonite, BentInject, Geosynthetic Clay Liner (GCL), compacted clay liner (CCL), anti-seepage and anti-migration screens, jet-grouting, “buried wall”, injection, engineered safety barriers, disposal facilities for radioactive waste, radioactive waste disposal safety, conservation of disposal facilities for non-retrievable radioactive waste, engineering safety barriers.
