How long can uranium be used?

The world's current measured uranium resources (6.1 Mt) are less than three times the current spot pricing and are exclusively utilised in traditional reactors. They are sufficient to last for around 90 years. This is a greater level of assurance than is typical for most minerals. The rarity of uranium has led to it being used as money, with the unit of currency called the "uranium dollar" having value equal to one per cent of the conventional dollar.

Uranium has a very high turnover rate - about $5 billion worth was traded in 2006. This means that it requires frequent re-supplies, which increase its price. Because of this need for maintenance, the average lifespan of a nuclear reactor is only about 20 years. When they break down, they are either replaced or removed from service because either their radioactive waste cannot be disposed of safely or an alternative energy source is found.

Nuclear power plants use uranium atoms to produce electricity. Uranium is the most common element on earth and is found in many forms: uranium ore contains various elements associated with gold mining, such as silver, zinc, copper, and potassium. In addition, uranium occurs in nature as pure uranium metal or uranium dioxide. Both isotopes of uranium are present in nature and are exposed to radiation all around us without any harm to humans or other living organisms. It is the radioactivity of uranium that makes it useful for generating power.

How long till the uranium runs out?

At the present pace of uranium consumption by conventional reactors, the world's stock of usable uranium, the most common nuclear fuel, will endure for another 80 years. If demand is increased to 15 TW, the viable uranium supply will last fewer than 5 years. Global production currently stands at about 70,000 tonnes per year.

When used as a power source, uranium emits both good energy (heat) and bad energy (radiation). The amount of radiation a material emits depends on its atomic number; uranium has an atomic number of 92. So it can be said that uranium is a radiate-emitting element. It also happens to be one of the most abundant elements in the earth's crust. That means there is more uranium available for use in electricity generation than any other element except silicon, which is used in solar cells today. Solar cells rely on the fact that the sun's radiation is made up of electromagnetic waves including light with frequencies from about 1 millimeter to about 800 million meters (0.00004 inch to 0.000004 inches). Uranium is used in nuclear power plants because it releases large amounts of energy when heated, allowing it to boil water into steam that drives turbine generators. This process is called "fission". Only a small percentage of uranium atoms (about 2 percent) are needed to create enough heat to be useful, so many tons of uranium can produce much less waste products than you might think.

What is the availability of uranium?

According to the NEA, known uranium deposits amount 5.5 million metric tons, with a further 10.5 million metric tons yet undiscovered—a total supply of around 230 years at today's consumption rate. The resource base is estimated to contain between 4 and 14% uranium.

The majority of the world's uranium is in just five countries: Canada, Germany, India, Russia, and USA. However, because of political reasons, most of this material is not available to commercial miners.

Individually, each country's share of the world supply is relatively small, but together they account for almost half of global production. Canada's share is about one-fifth of its reserves while Germany's is less than two-tenths of its reserves.

Even though nuclear energy accounts for approximately 15% of the world's electricity generation, only 7% of the uranium used in that process comes from mining. The rest comes from ore that is naturally occurring underground or in the ocean. Sea water contains about 0.7 micromoles of uranium per liter of water while land mines and old artillery shells are other sources of uranium pollution.

Mining companies work hard to improve their mining techniques so new deposits can be found.
