How much do nuclear power plants cost?

Answer 1

To give you an idea,Calvert Cliffs III (Maryland) is being built by UniStar, a joint venture of Constellation Energy Group and Électricité de France, which is 85 percent owned by the French government. Its current cost estimates approach $10 billion dollars.
Different size plants cost different ammounts, so most published estimates are given in dollars per kW of production capacity. Even then, estimates for new construction vary widely. See related link ...

Answer 2

The UK recently estimated that it would cost £1.2b per station.

In comparison to other forms of power, it would cost £800m for a gas-fired station and £1b for a coal-fired one. But the costs of supplying these stations are a lot higher (80% compared to 10% for nuclear)

Modern reactors make about 1400MW of electricity. An offshore wind turbine is rated at 3MW but only reaches about 40% of that capacity because of wind conditions. This means that you would need 1166 wind turbines.

The Thanet offshore wind farm is currently the world's largest wind farm. It's 100 turbines cost the UK £900m. It has a capacity of 300MW and covers 35 square kilometers.

This means to get the same power as a nuclear station from wind would cost £10.4b and would take up 406 square kilometers.

Answer 3

It costs around 7 billion dollars and 12+ years to build a Nuclear power plant with a single reactor. The cost all depends on the type of power plant and number of reactors it has. Some power plants have 6 reactors. I'm not even sure how much that would cost. Maybe 10-15 billion dollars.

Answer 4

The cost of any power plant can be divided into capital construction costs, i.e. the physical material inputs such as steel and concrete and other equipment along with the workers' labor; and costs of financing the project, i.e. interest on borrowed money. So-called "overnight" cost estimates are useful because they focus only on the capital costs of the engineering, procurement, and construction of the physical plant itself.

A NEI white paper published in September 2010 estimates the "overnight" cost of a generation III+ nuclear reactor at about $4,000 per kilowatt of rated generating capacity, comparable to a new emissions controlled pulverized coal boiler, and less than the new design IGCC (Brayton & Rankine cycle) coal generators. NEI's estimate agrees with other "overnight" cost estimates from MIT, the EIA, and the Brattle Group; a 2008 Congressional Budget Office report estimated nuclear capital costs at only $2,358/kW(e).

Cost estimates of state public utilities filings from Progress Energy, FP&L, and SCE&G included additional Balance-of-Plant (BOP) costs (cooling towers, water intake, roads, switchyards, administrative buildings, permits) along with extensive transmission line improvements and, most significantly, the "risk premium" to finance all of this ran as high as $10,000/kW(e).

The capital cost of the EPR reactor now under construction in Finland is running at about $4,000/kW(e).

Apparently, it costs approximately 40p to build a nuclear power station out of LEGO.

it is going to be 1 million pounds to set it up
