Description

Immobilization of uranium simulative of actinide component of radioactive wastes (RAW) in a large-sized mineral blocks using the powder-like high-energy metallized fuel has been investigated. Chemical reactor on the base of steel container as well as RAW immobilization technology were developed. The composites obtained give a sure radionuclides immobilization. Interphase distribution of uranium and hafnium in polymineral block is studied

Abstract (Russian)

Исследована иммобилизация урана, имитирующего актинидную составляющую радиоактивных отходов (РАО), в крупногабаритные минеральные блоки с применением порошкообразного высокоэнергетического металлизированного топлива. Разработаны химический реактор на базе стального контейнера и технология иммобилизации РАО. Получаемый композит обеспечивает надежную фиксацию радионуклидов. Изучено распределение урана и гафния между фазами полиминерального блока
