Abstract (en)

[origin: BG64066B1] The method is used in the nuclear power generation industry. By it containers for radioactive objects having high intensity of the neutron source are produced. By the method a hollow cylindrical intermediary space (3), formed between a metal outer jacket (1) and a metal inner jacket (2) is filled by filler of concrete with the finest grain size distribution. The residual space is filled by a suspension of cement, water and additives. Such a container can be used for high-dosage, powerful neutron sources. It has compact overall dimensions when in the intermediate space (3) two separation spaces (31 and 32) are formed, concentric to each other, by means of a diaphragm (8) the passage holes of which are smaller than the smallest grain size. The filler is of concrete, as well as the suspension are introduced only in one of the two separation spaces. 10 claims, 2 figures
