CONTAINER FOR LONG-TERM BURIAL OF HAZARDOUS WASTES Russian patent published in 2013 - IPC G21F5/00 

FIELD: power engineering.

SUBSTANCE: container for long-term burial of hazardous wastes includes a body assembled with a cover, onto the outer surface of which the protective coating is applied. The coating contains an organosilicate composition OS-51-03 with additives, one of which is sodium-chrome pyrophosphate with particle size of 40-80 nm, in the amount that is less or equal to 0.1 wt % of the organosilicate composition, and another one - zirconium or titanium dioxide with particle size of 80-120 nm, in amount of (0.5-1.0) wt %. At the same time the hardener is the product AGM-9.

EFFECT: invention makes it possible to create a container, a protective coating has: high radiation resistance, high strength, wide range of working temperatures and high moisture resistance.
