The risk people aren't considering is public opinion. It takes about 10 years to build a nuclear power-plant. Historically when have had one major accident every 30 years. Each time an accident have happened, projects have been canceled or put on ice. This mean that if you start planing a power-plant today there is ~33% chance, public opinion will stop it before its completed. One good illustration id the documentary "Inside Bills head". Bill gates spent untold millions to develop safer, cleaner, less expensive nuclear power. One day he woke up to the news of the accident in japan, and all of a sudden all partners pulled out, permits where revoked and no one was interested anymore. (The costs, risks and time lag are more important arguments against nuclear, but I think this one is worth considering too)
