uranreserverna

Uranreserverna, or uranium reserves, are quantities of uranium that can be extracted economically with current technology and prices. They are a subset of uranium resources, which include discovered deposits not yet economical to mine and undiscovered deposits. Reserves are commonly categorized by confidence and economic viability: proven or measured reserves represent high confidence that the uranium can be mined profitably, while probable or indicated reserves have intermediate confidence; resources extend to inferred and speculative categories.

International reporting frameworks typically differentiate reserves and resources into categories such as Reasonably Assured Resources (RAR) and Estimated Additional Resources (EAR), reflecting different levels of geological certainty. The definitions hinge on prevailing market prices and technological feasibility, so reserves can change with price, exploration success, or changes in technology.

Geographically, uranium reserves are concentrated in a few countries. The largest known deposits are found in countries such as Kazakhstan, Canada, and Australia, with additional important reserves in Namibia, Niger, and other regions. Global production is led by a few large producers, and reserve estimates are periodically updated as new discoveries are made or as existing deposits are re-evaluated.

Uranium is mainly used for fuel in civilian nuclear reactors. The size of reserves and the expected duration of supply depend on demand for nuclear energy, reactor retirements, exploration progress, and uranium prices. Environmental and regulatory considerations, including mining impacts and waste management, influence how and where reserves are developed.
