UA56381U - Neutron-protective titanium hydride - Google Patents

Abstract

A neutron-protective titanium hydride, composition of which is determined by the following formula of TiH, wherein weight coefficient of neutron removal is in 1.5-1.6 times greater.

Description

p is the numerical value of the linear coefficient y. The mass removal coefficient y depends on the conduct shows that during the passage of the material layer only on the chemical composition of the material, a linear metal with a thickness of 1 cm, the neutron flux density, the removal efficiency tsu and the relaxation length GI. decreases by a factor of 1 (nD-sh"r, e-2.71828, p-2.435 depends on the chemical composition of the material and its density g/cm3). For all materials, calculations of conductivity p (ra:t/M ). Therefore, when comparing different samples, at p-2.435 g/cm3, as a criterion for radiation-protective properties,

It is the thickness of the layer of the substance, if desired, it is expedient to choose a mass coefficient for the removal of which the neutron density decreases daily. time. The results of experiments (tests) and assessment of radiation protection efficiency are shown in the table.

Analyzing the data of the table and examples, it is possible to make a scrap for industry. This is a powder from which it is easy to conclude that the model proposed by us forms products of the required geometry for a material with a hydrogen content that corresponds to the formula for use as protection against radiation exposure.

TiNne" has the following advantages in comparison with the existing ones in nuclear energy and nuclear technological material: heat, as well as a sintering activator in powder metallurgy, and as a source of environmentally friendly fuel.
