What is the thermal efficiency of the nuclear process for generating electricity and how does it matter?

already exists.

Would you like to merge this question into it?

already exists as an alternate of this question.

Would you like to make it the primary and merge this question into it?

exists and is an alternate of .

The new General Electric 9H and the Siemens competitive equivalent gas turbines are claiming a 60% efficiency by using combined gas and steam generation to scavenge as much energy as possible from the input gas.
Similar figures might be obtained from closed cycle gas nuclear systems, but to date have not been recorded. Work with 35% to 45% at the moment.

It is important in that much of the energy in a generating station is wasted, and simply heats up the local atmosphere. There is a financial cost, and with conventionally fuelled power stations, a big pollution cost. Nuclear stations are much cleaner.

Which is more efficient way to generate electricity - solar thermal plants or photovoltaic plants?

I cant answer this question fully. However I do know that mass produced PV panels generally reach around 12-16% efficiency. It is possible to reach far higher efficiencies but not on a mass produced basis, so high efficiency PV cells only tend to make it onto special projects such as space flight ( Full Answer )

How does nuclear fuel generate electricity?

Thermal efficiency of nuclear power plant?

The average thermal efficiency of a nuclear power plant, which accounts the heat produced in the reactor and the electricity produced in the turbo generator, is about 33-34%, varying on the type of the reactor as well as which fluid is used to cool the reactor and transfer the heat.

To generate electricity nuclear power plants produce?

Nuclear reactors should not be used to generate electricity?

False. Nuclear power is used to generate about 25% of the electricity in the United States, and about 75% of the electricity in France. Nuclear power is far safer than coal-fired power plants, and produces no harmful emissions, if you care about such things.

Can nuclear fission be used to generate electricity?

Yes, nuclear fission results in loss of mass (or mass defect) that transforms into energy according to formula E = mc2 (c is light velocity).
