AS THE world prepares for the largest investment in nuclear power in decades, owners of uranium mines last week raised the prospect of fuel shortages. To make things worse, the reliability of estimates of the amount of uranium that can be economically mined has also been questioned.Volatile oil and gas prices, along with the threat of global warming, have pushed governments to reconsider nuclear energy, partly because it is a low-carbon technology and partly because uranium supplies seem plentiful.Mined uranium caters for about 60 per cent of the global demand for nuclear fuel. The rest comes from secondary sources, including stockpiles left over from the 1970s and 1980s, reprocessed fuel and the conversion of old Russian nuclear warheads - the so-called Megatons to Megawatts programme.But the supply may not be as secure as first thought. The price of uranium has plummeted from a peak of around $130 per pound of uranium oxide ($286 per kilogram) in 2007 to $45 today(see graph). Some of this decline is due to slumping fossil fuel prices and some from the uncertainty surrounding the industry.

Where is nuclear energy obtain from?

Nuclear energy is obtained from the process of nuclear fission, where the nucleus of an atom is split into smaller parts, releasing a large amount of energy. This process is typically carried out in nuclear power plants using uranium or plutonium as fuel.


Is fission nuclear energy chemical energy or mechanical energy?

Nuclear fission is a type of nuclear reaction that converts nuclear energy into thermal energy (heat), which can then be used to generate mechanical energy (such as electricity). So, fission nuclear energy originates as nuclear energy and can be converted into mechanical energy.

Is fission reverse energy?

No, nuclear fission is not reversible energy. It is irreversible process.


What is nuclear fission energy?

Nuclear Fission Energy is energy that is produced using fissionable elements. The most common is Uranium. Fission energy involves the fission heating water and turning a turbine, much like coal.


Is nuclear energy obtained from radiation?

Not precisely. The current technology of nuclear energy gets energy from fission. Fission produces radiation, as well as energy.
