| Popis: | The authors consider a method of investigating gas evolution from absorbing materials by using the principle of a gas controlled heat pipe. The dependence of gas evolution from crystalline boron is studied on the thermal neutron fluence and the irradiation temperature. A schematic diagram of the arrangement for measuring gas evolution by this method is shown. The method enables one to determine the amount of gaseous products of a nuclear reaction which enters the volume occupied by uncondensed gas. Relations obtained show that the helium yield from boron powder of a given dispersion occurs more rapidly the higher the irradiation temperature and the thermal neutron fluence. With an increase in temperature the diffusion of gas bubbles to the surface of the powder particles increases, and the boron crystals are fractured as a result of irradiation. |
