将下列段落翻译 Proponents of nuclear energy argue that nuclear power is a sustainable energy source which reduces CO 2 emissions and can increase energy security if its use supplants the dependence on imported fuels. Proponents advance the notion that nuclear power produces virtually no air pollution, in contrast to the chief viable alternative of fossil fuel. Proponents also believe that nuclear power is the only viable course to achieve energy independence for most Western countries. They emphasize that the risks of storing waste are small and can be further reduced by using the latest technology in newer reactors, and the operational safety record in the western world is more excellent than the other major kinds of power plants.
