ANNOTATION:

High-molecular compounds have been studied, as well as their relationship with other materials and modifications made based on various additives introduced. Their findings helped to initiate the development of technologies providing control over the adsorption process at the phase boundary and polymerization under thermal conditions. The paper discusses a method developed involving thermoplastic polymer of the polyolefin (polyethylene) class applied to concrete and metal surfaces. This material has high adhesive capacity, is resistant to abrasion, corrosion and other destructive factors. Thanks to its improved characteristics this polymer can be considered as an additional waterproofing material in the designs of engineered safety barriers for radioactive waste Class 3 and 4 disposal in near-surface disposal facilities (NSDF).

Keywords: radioactive waste, radioactive waste disposal facility, polyethylene, conditioning agent, adhesion to steel, adhesion to concrete, chemical inertness, polymer coating, flame spraying, coating quality control.
