AUSTRALIA could not develop a domestic nuclear power industry in time to stave off the effects of climate change and such a program would be prohibitively expensive, energy experts say. The cost of building the large number of nuclear power stations needed to even partly replace coal as a source of electricity would be so heavy no private investor would take on the risk without huge government subsidies, they said. The Federal Treasurer, Peter Costello, warned at the weekend that Australia would have to get used to the idea of a domestic nuclear power industry because it was part of the solution to global warming. Scientists have warned the world needs to make large cuts in greenhouse gas emissions now to avoid further big changes to weather patterns. But coal-fired power plants could not be replaced fast enough with nuclear plants to make any real difference, said the research principal at the Institute for Sustainable Futures, Chris Riedy. "It would take 10 years to get one nuclear power plant up even if there was no public protest," Dr Riedy said. "And all of the evidence from where they have been built [overseas] shows they have had to have massive [government] subsidies to keep them going." A 1000-megawatt nuclear power plant would generate between 2 and 3 per cent of Australia's current electricity consumption, said Dr Iain McGill, research co-ordinator for the Centre for Energy and Environmental Markets at the University of NSW. "Coal generation is about 85 to 90 per cent of national electricity market generation, so it might require around 30 to 40 such plants to replace coal-fired generation," he said. "Such a program would almost certainly take numerous decades." Dr Mark Diesendorf, a senior lecturer at the Institute of Environmental Studies at the University of NSW, said a 1000-megawatt nuclear plant would cost at least $3 billion to build - 2½ times that of a coal-fired power plant - and much more to operate than fossil fuel plants. To build a lot of nuclear plants, say, over 20 years, would emit so much greenhouse gas it would take 40 years to break even in terms of CO
