If you look at nuclear vs coal, it's easy, right? Let the industry pay for all its expenses - healthcare, compensation to victims, safety, etc.etc. Then let free market decide what works best. Ideally, one doesn't even need to sit down with a calculator to decide which technology is best - free market includes that feature. :) Gov't does need to make sure that the industries play by the rules (see above). Other than that, it's nobody's business. Same with gas vs electric cars, etc.
