| Abstract Scope |
The use of moderators in advanced reactors can allow for less fuel and result in smaller reactors, which is particularly useful when there are space or weight constraints for the ultimate reactor application or location. Metal hydrides are strong neutron moderator candidates because they contain a high hydrogen density and are phase stable at much higher temperatures than water. This talk will discuss research at Los Alamos National Laboratory studying fabrication techniques and property measurements in a variety of metal hydride moderator materials, focusing on Zirconium and Yttrium Hydrides. Stoichiometry, phase, and fabrication methods and their effect on thermophysical and thermomechanical properties will be presented. |
