Exemption Guidance: Uranium and thorium
It is legal to have uranium and thorium compounds listed on a permit but they still count towards the 5 kg limit for exemption. Above a total of 5 kg of uranium and thorium, they all need permitting. Some current permits may include uranium and thorium which can be exempt and these continue in operation until varied. In future only in

US4493809A Uranium thorium hydride nuclear fuel
A nuclear fuel includes uranium dispersed within a thorium hydride matrix. The uranium may be in the form of particles including fissile and non-fissile isotopes. Various hydrogen to thorium ratios may be included in the matrix. The matrix with the fissile dispersion may be used as a complete fuel for a metal hydride reactor or may be combined with other fuels.

The distribution of uranium and thorium in granitic
Some secondary uranium deposits are thought to have formed from uranium derived by the weathering of silicic igneous rocks such as granites, rhyolites, and tuffs. A regional geochemical survey was made to determine the distribution of uranium and thorium in granitic rocks of the Basin and Range province in order to evaluate the potential for secondary uranium occurrences in the area.
