Currently, the United States, the world's top nuclear power producer, has 104 plants that generate 20 percent of the country's electricity.

Nuclear power, which has near-zero emissions of carbon dioxide, has recently come back into fashion as an alternative to generating electricity from coal and other carbon-based sources that contribute to global warming.

While the report also supported storing US nuclear waste at power plants until the long-stalled Yucca Mountain repository opens, 10 dumps the size of Yucca Mountain would be needed to store the extra generated waste by the needed nuclear generation boom.

That outlook was too optimistic in light of how many new nuclear plants are currently on the drawing board, the report said.

The needed rate of expansion would be faster than during the industry's first 40 years and than the Energy Information Administration's forecast for the next 30 years in the United States.

Some individuals differed, though, on how much the industry will expand, and said it could still make some type of impact.

Twenty-seven individuals from organizations spanning a broad ideological spectrum, including the Natural Resources Defense Council and GE Energy, spent nine months on the report, called "The Nuclear Power Joint Fact-Finding."

The group, which was brought together by the nonprofit Keystone Center, said that as companies limit generating electricity from coal and other fossil fuels, there will be more financial incentives to build nuclear power plants.

SPREADING NUCLEAR ARMS

The Keystone panelists also said that President George W. Bush's Global Nuclear Energy Partnership could help countries and groups interested in building nuclear weapons obtain plutonium, the key ingredient in those munitions, which could help spread nuclear weapons.

While the Union of Concerned Scientists, a nonprofit organization of scientists focused on the environment and security, had trouble with most of the report, it agreed with assertions on GNEP.
