The University of Florida has underway a research program to validate the benefits of developing a Pu/ZrH/U matrix fuel for the irradiation of the U.S. weapons plutonium and European reprocessed plutonium from an economic, operational, and performance basis. Thermal reactors using plutonium as a fuel are inherently undermoderated because of the large absorption cross sections of plutonium and the presence of large absorption resonances for plutonium in the thermal and near‐thermal energy ranges. The use of the proven TRIGA ZrHx‐based fuel with plutonium has shown an extremely large (>20%) increase in reactivity over the conventional UO2/PuO2 fuel form currently being considered, with an additional major increase in the destruction of plutonium, rendering it an extremely attractive fuel form for plutonium disposition.
