Large Aircraft. There is no emergency shutdown on large aircraft, as there is on Nuclear Reactors. Imagine an Airbus 380 crashing into Manhattan during rush hour. They don't allow nuclear reactors in Manhattan. Obvious another example of where Nuclear is irrationally opposed by Government & the Press vs other vastly more dangerous technology. Now why would that be? Follow the Money.<br /><br />Large Aircraft Assembly Line production methods are a good model for the production of medium sized nuclear reactors in the 100 to 500 MWe range. The key is demand must be high enough and governments must give a clear signal that they will support with words AND DEEDS, factory production of small and medium sized nuclear reactors. Certainly with high Carbon Taxes and the coming explosive rise in Fossil Fuel prices, the demand will be more than adequate.Warren Heathnoreply@blogger.comtag:blogger.com,1999:blog-7597656451205429515.post-7873381870663595502009-04-28T10:01:00.000-05:002009-04-28T10:01:00.000-05:00The comparison between the LFTR and the Airbus 380...The comparison between the LFTR and the Airbus 380 is interesting.<br /><br />The money to develop a commercial LFTR is certainly within the reach of a number of large companies and even a few individual.<br /><br />The difference between the LFTR and the Airbus 380, I believe, is in government regulation. The A-380 is being regulated for its success. That regulation certainly includes safety, emissions, and noise. These requirements have been tightened incrementally over the years, but they apply to all new aircraft being manufactured, whether of old or new design. These regulations are the things necessary to make the aircraft acceptable in the market. In a way, they may be "hurdles", but they are necessary hurdles. Once past these hurdles, I don't expect that there will be actions taken by various groups to prevent the entrance of the A-380 into the market. The success of A-380 will determined by the market. Investors recognize this market risk, and accept it as a normal part of doing business. From a business point of view, satisfying regulatory requirements is simply another part of the development, much like fuel burn and flight range.<br /><br />Contrast this with the regulatory climate for reactor development. Safety regulation seems to be used not as a mechanism to make nuclear reactors acceptable in the market, but as a method to prevent them from being built at all. Unlike for aircraft, the level of safety demanded for a new nuclear reactor is not applied as well to a newly constructed coal plant.<br /><br />I think we are correct to expect a higher standard of safety with nuclear reactors, but if the safety bar is raised so high as to prevent the development of advanced nuclear reactors, safety is degraded as we continue to use old coal-fired power plants, and build new ones.<br /><br />Similarly, radioactive emissions. It is easily shown that radioactive emissions into the general environment from a coal-fired power plant are much higher than for a nuclear plant. Once again, I think we should expect a higher standard for nuclear plants, but not so high as to prevent them from being constructed and benefitting society.<br /><br />Given that regulation seems to be more about placing obstacles in the way of advanced reactor development than about benefit to society, is it any wonder that so few large companies and individuals are willing to invest in the development of advanced reactors?donbnoreply@blogger.com
