Background . About 92 IAEA Member States have historically or are currently exploring for uranium or thorium. In the past 30 years, 75% or more of the projects in the Uranium Production Cycle that have been supported through the IAEA Technical Cooperation programme were focussed on aspects of uranium exploration.

(Updated November 2020) Thorium is more abundant in nature than uranium. It is fertile rather than fissile, and can only be used as a fuel in conjunction with a fissile material such as recycled plutonium. Thorium …

Uranium (chemical symbol U) is a naturally occurring radioactive element. In its pure form it is a silver-coloured heavy metal, similar to lead, cadmium and tungsten. Like tungsten it is very dense, about 19 grams per cubic centimetre, 70% more dense than lead. It is so dense a small 10-centimetre cube would weigh 20 kilograms. The International Atomic …

Uranium mining in Asia is on the rise as a number of countries in the region are showing interest in nuclear power. More than 25 experts discussed the socio-economic outlook of radioactive and associated minerals production in Asia at a workshop in Yogyakarta, Indonesia last month. The meeting was part of a new, four-year IAEA …

These radioactive elements are radon (Radon 222), thoron (Radon 220) and by products formed by the decay of radium (Radium 226) and thorium present in many sorts of rocks, other building materials and in the soil. By far the largest source of natural radiation exposure comes from varying amounts of uranium and thorium in the soil around the …

International Atomic Energy Agency Espoo, Finland 29 May–2 June 2023 Ref. No.: EVT2201313 Information Sheet Introduction About 92 IAEA Member States have historically or are currently exploring for uranium or thorium. In the past 30 years, 75% or more of the projects in the Uranium Production Cycle that have been supported

Uranium is the primary fuel for nuclear reactors and must be managed properly, in a safe and sustainable manner. Recent annual production of natural uranium world-wide has been between 55,000 and 65,000 tons of uranium metal, similar to the fuel demand. Additionally, thorium is also being investigated as a potential alternate source …

1. Introduction. Uranium and thorium are the only naturally-occurring actinides in the Periodic Table of the Elements, and share many similar properties such as: the order of magnitude of the half-lives of their most abundant isotopes (238 U and 232 Th), their primary modes of radioactive decay, and the high melting points and insolubility in …

Description. Research has been published over the past few decades on the possible use of thorium in various nuclear power reactor types. Therefore, it is worthwhile to analyse the supply situation for additional …

IAEA safeguards play an indispensable role in preventing the spread of nuclear weapons by ensuring that nuclear material remains in peaceful use. Uranium mines and milling facilities handle large amounts …

Certain minerals, including some that are commercially exploited, contain uranium, thorium or potassium at elevated concentrations. During the extraction of minerals from the Earth's crust and their physical or chemical processing, the radionuclides may become unevenly distributed between the various materials arising from the process.
