The performance of the world’s nuclear reactors in 2020 are set out in  World Nuclear Association Performance Report 2021 , which was published 1 September 2021. 

There has been more than 40 years of experience in applying international radiation safety regulations at uranium mines. Uranium mining companies have taken steps to reduce radiation doses wherever and whenever they can.

Controlling the spread of disease, helping doctors diagnose and treat patients, powering space exploration; the uses of nuclear technology are varied – and truly life-changing.

The mean capacity factor for reactors over the last five years shows little variation with age after the initial start-up of the reactor. For reactors beyond 40 years of operation there is a slight increase in average capacity factor. Source: World Nuclear Association, IAEA ...

Radioisotope power sources have been an important source of energy in space since 1961. Fission power sources have been used mainly by Russia, but new and more powerful designs are under development in the USA.

Fuel fabrication is the final stage in nuclear fuel preparation prior to use in a reactor. Nuclear fuel assemblies are specifically designed for particular types of reactors and are made to exacting standards.

Nuclear power is cost competitive with other forms of electricity generation, except where there is direct access to low-cost fossil fuels. In assessing the economics of nuclear power, decommissioning and waste disposal costs are fully taken into account.

The Earth's uranium has been thought to be produced in one or more supernovae over 6 billion years ago. More recent research suggests it could also be created through the merger of neutron stars.

Germany's Energiewende (energy transition) is a national program to change to a renewable-dominated energy system and phase out nuclear power. The government has estimated that the total cost of this could reach €1 trillion.
