Nuclear power is potentially extremely unsafe  It is unfortunately the case that the nuclear industry has a bad reputation for safety. This is undeserved. The overwhelming majority of nuclear reactors have functioned safely and effectively for their entire lifetimes. The four historic nuclear disasters (1957 Windscale Fire, 1979 Three Mile Island and 1986 Chernobyl, 2011 Fukushima, Japan) killed fewer people than the oil and coal industries have1. "The multi-agency U.N. Chernobyl Forum reported last year that 56 deaths could be directly attributed to the accident, most of those from radiation or burns suffered while fighting the fire. Tragic as those deaths were, they pale in comparison to the more than 5,000 coal-mining deaths that occur worldwide every year"2.  Further, the two major nuclear accidents, at Three Mile Island and Chernobyl, were both in old style reactors, made worse in the latter case by poor Soviet safety standards. The Chernobyl disaster took place at a time when our understanding of nuclear issues was much lesser than it is now, and was the result of poorly trained staff in the plant's control room. Power stations today are better staffed, better maintained and better understood, and because the effects of an attack upon them are acknowledged, they are better defended and monitored by the armed services. No system can be 100% safe, but solid design principles can minimize risk.  Perhaps the best guarantee of safety standards in the nuclear industry is the increasing transparency with which the industry is presenting itself. Many of the problems in its early days were caused by excessive control due to the origin of nuclear energy from military applications. As the gap between the two separates so the nuclear industry becomes more accountable. The question is, is the slight risk of a nuclear accident a worse danger than the inevitable climate catastrophe that awaits us?  1 'Risks of Nuclear Power' by Bernard Cohen, University of Pittsburgh, 2Patrick Moore, a prominent environmentalist and founding member of Greenpeace, "Going Nuclear A Green Makes the Case", Washington Post, 4/16/06"
