Particle size distributions of aerosols generated in the hydriding of uranium.

摘要

wo methods, surface area and particle size determination, were used for investigation of particle size distributions generated during hydriding-dehydriding cycles of uranium. The initial pressure of each hydriding was in the range 156.518 to 219.845 kPa at room temperature. Dehydriding was carried out under vacuum conditions at a temperature between 573 to 800 K. Particle size determinations were carried out using 5 ;After 42 cycles the geometric mean particle diameters of uranium and hydrides were 0.377
