A comparison of regularly up-dated assessments of global uranium availability is given in <xr id="fig:REMIND_1"/>. Conventional identified resources of uranium are differentiated into recovery cost categories. The assessment by the Nuclear Energy Agency [1] comprises 6.3Mt of uranium, which equals approximately one hundred times current reactor requirements. The estimates of World Energy Council [2] and German Geological Survey [3] mainly rely on the numbers of NEA but apply different interpretations for identified uranium resources. The more uncertain category of conventional undiscovered uranium resources are also assessed differently by the three institutions.
For the default version the assumption is that 23MtUr are ultimately available with increasing extraction costs up to 260$US per tUr. The implementation uses a quadratic extraction cost function for each region that starts at 25US$ per kg uranium and cuts off at the same marginal costs (300$US per kg uranium), if - at the global level - 23MtUr are reached. The shape parameter of the regional extraction cost functions depend on the regional availability of uranium resources. The default version does not represent reprocessing and fast breeding reactors integrated into the nuclear fuel cycle. Given the optimistic assessment of uranium resources this assumption is economically reasonable in the near-term[4].
