Questioning nuclear power's ability to forestall global warming

Rising energy and environmental costs may prevent nuclear power from being a sustainable alternative energy source in the fight against global warming, according to a study in the April 1 issue of ACS’ Environmental Science & Technology.
In the article, Gavin M. Mudd and Mark Diesendorf investigate the “eco-efficiency” of mining and milling uranium for use as fuel in nuclear power plants. Advocates of nuclear power claim it has the potential to mitigate global warming. Detractors, however, link it to dangers such as proliferation of nuclear weapons and problems such as permanent disposal of nuclear waste.
The study points out that supplies of high-grade uranium ore are declining, which may boost nuclear fuel's environmental and economic costs, including increases in energy use, water consumption and greenhouse gas emissions. In addition, newly discovered uranium deposits may be more difficult to extract in the future — a further drain on economic and environmental resources.
“The extent of economically recoverable uranium, although somewhat uncertain, is clearly linked to exploration effort, technology and economics but is inextricably linked to environmental costs, such as energy, water, and chemicals consumption, greenhouse gas emissions and broader social issues,” the authors say.
“These issues are critical to understand in the current debate over nuclear power, greenhouse gas emissions, and climate change, especially with respect to ascribing sustainability to such activities as uranium milling and mining.”

Basically, the environutjobs are going to put down as unworkable ANY technology that could get us out of the conundrum that they've invented with "global warming". The reason they're doing that is that they want the world to be top-down run by creeps like themselves who know best what the rest of us should be doing.
Sadly, what they think that we should be doing, all six billion of us, is starving in some opium dream of a pre-industrial nirvana that they have.
