ISSUE BRIEF

FINDINGS

Within the past year, estimates of the cost of nuclear power from a new generation 
of reactors have ranged from a low of 8.4 cents per kilowatt hour (kWh) to a high 
of 30 cents. This paper tackles the debate over the cost of building new nuclear 
reactors, with the key findings as follows:

• The initial cost projections put out early in today's so-called "nuclear 
renaissance" were about one-third of what one would have expected, based 
on the nuclear reactors completed in the 1990s.

• The most recent cost projections for new nuclear reactors are, on average, over 
four times as high as the initial "nuclear renaissance" projections.

• There are numerous options available to meet the need for electricity in a carbon-
constrained environment that are superior to building nuclear reactors. Indeed, 
nuclear reactors are the worst option from the point of view of the consumer 
and society.

• The low carbon sources that are less costly than nuclear include efficiency, 
cogeneration, biomass, geothermal, wind, solar thermal and natural gas. Solar 
photovoltaics that are presently more costly than nuclear reactors are projected 
to decline dramatically in price in the next decade. Fossil fuels with carbon 
capture and storage, which are not presently available, are projected to be 
somewhat more costly than nuclear reactors.

• Numerous studies by Wall Street and independent energy analysts estimate 
efficiency and renewable costs at an average of 6 cents per kilowatt hour, while 
the cost of electricity from nuclear reactors is estimated in the range of 12 to 20 
cents per kWh.

• The additional cost of building 100 new nuclear reactors, instead of pursuing a 
least cost efficiency-renewable strategy, would be in the range of $1.9-$4.4 trillion 
over the life the reactors.

Whether the burden falls on ratepayers (in electricity bills) or taxpayers (in large 
subsidies), incurring excess costs of that magnitude would be a substantial burden 
on the national economy and add immensely to the cost of electricity and the cost 
of reducing carbon emissions.

APPROACH

This paper arrives at these conclusions by viewing the cost of nuclear reactors 
through four analytic lenses.

• First, in an effort to pin down the likely cost of new nuclear reactors, the 
paper dissects three dozen recent cost projections.

• Second, it places those projections in the context of the history of the nuclear 
industry with a database of the costs of 100 reactors built in the U .S. between 
1971 and 1996.
