Decreases the share of renewable energy sources in the energy mix.
Likely to decrease energy independence by increasing nuclear fuel imports.
Reduces global CO2 emissions.
Generates radioactive waste.
In the case of nuclear disaster, the impact on the environment may be large.
In the case of nuclear disaster the impact on the society and on the economy may be large.
May increase cost of electricity production as new nuclear power plants may cost significantly more than the existing ones.
Nuclear power plants use the energy that is produced when the nucleus of a heavy atom (e.g. uranium) is broken, what is known as fission energy. This energy is released as heat, which is used to produce high pressure steam. The steam is sent to a turbine where it is expanded to produce work. Finally the mechanical energy (work) of the turbine is transformed into electricity in an alternator.
The operation of nuclear power plants produces very low carbon dioxide emissions (CO2), but generates radioactive nuclear waste. These nuclear wastes are currently in temporary storage facilities.The scientific community estimates that the best option for long term storage of these wastes is to burry them in deep geological formation in the Earth crust.
Next tables contain the assumptions that have been introduced in the Nuclear power plant energy model of the calculator.
