Formation of plutonium hydride PuH2: description of the reaction rate surface as a function of pressure and temperature.

PDF Version Also Available for Download.

Description

T he hydriding reaction of plutonium metal is used increasingly in the recovery and processing of plutonium. There is thus an increased need for an understanding not only of the thermodynamic parameters governing the reaction, but also of the kinetic behavior to be expected with variations in process parameters such as pressure and temperature . A mathematical description of the behavior of the hydriding process in the entire reaction space in P, T, and rate provides a predictive capability, and enables the reaction rate to be optimized. In addition, given a well-defined description of this rate surface as a function ... continued below

Description

T he hydriding reaction of plutonium metal is used increasingly in the recovery and processing of plutonium. There is thus an increased need for an understanding not only of the thermodynamic parameters governing the reaction, but also of the kinetic behavior to be expected with variations in process parameters such as pressure and temperature . A mathematical description of the behavior of the hydriding process in the entire reaction space in P, T, and rate provides a predictive capability, and enables the reaction rate to be optimized. In addition, given a well-defined description of this rate surface as a function of pressure and temperature, process parameters may be selected to optimize other important parameters such as particle size . These parameters may in some cases be mapped as regions or separate functions onto the surface described here .
