Extra-Heavy Concrete and Cermet: Protective Materials with Enhanced γ-Ray Absorption

This article is devoted to the development and study of new protective materials containing depleted uranium dioxide for increasing the capacity for γ-ray absorption. The materials were developed for use in multipurpose containers for spent nuclear fuel. The results of work on obtaining high-density concrete and cermet are presented. The recipe and technology for fabricating concrete (RZK–VNIINM) with density 6.5 g/cm 3 have been patented. A method of obtaining a high-density composition of corrosion-resistant steel and depleted uranium dioxide (cermet) with density 8.3 g/cm 3 has been developed.
