Statistical model of global uranium resources and long-term availability

Abstract: Abstract. Most recent studies on the long-term supply of uranium make simplistic assumptions on the available resources and their production costs. Some consider the whole uranium quantities in the Earth's crust and then estimate the production costs based on the ore grade only, disregarding the size of ore bodies and the mining techniques. Other studies consider the resources reported by countries for a given cost category, disregarding undiscovered or unreported quantities. In both cases, the resource estima… Show more

“…Including noneconomically viable sites, estimating this value is equivalent to estimating the expected amount of uranium ore in the Earth’s crust, i.e., about 3 ppm (0.0003%). Economically viable mines are found to have an average uranium tenor of 0.15%, a value widely used in nuclear power LCA literature. ,, The distribution of available tonnage with respect to ore grade can be estimated from the World Distribution of Uranium Deposits (UDEPO) database maintained by the IAEA. According to Monnet et al, the best fit for this distribution (over the UDEPO database) is a log-normal curve of average 1544 ppm and a standard deviation of 1299 ppm. These values are retained to model the ore grade distribution process in the life cycle inventory.…”

“…Ore grade is the parameter with the highest variation: the lowest economically viable mines’ ore contains about 300 ppm of uranium (0.03%), whereas at the other end of the spectrum, some Canadian mines offer ore grades up to 20% .
