I'm thinking of the scenario where the economy completely collapses, and safety precautions at nuclear power plants become inadequate due to workers walking off the job, or possibly a major mistake, negligence, incompetence, or sabotage occurs, resulting in a meltdown. How about an earthquake, or some failure of equipment or structural damage that went unforeseen? We saw an event happen at Chernobyl in the old USSR around the time of their economic collapse, and couldn't such a thing happen here in the U.S.? Is it worth taking the chance of such a disaster? Can you lay these fears to rest?
