I'm not sure I fully understood you, but I think you're asking about other countries. I don't know the situation in other countries; I do know the origins of the problem.
The origins of the problem date back to 1953, when Eisenhower made his “Atoms for Peace” speech at the UN. This led to a study in 1957 in the United States called the Brookhaven report. The report said that a small reactor of 200 megawatts, 20 miles from the city, could cause over $7 billion in off-site damages—back then.
Now, when the insurance industry was called to a congressional committee to testify about providing coverage for that, the insurance people said, “You must be crazy, we cannot possibly cover that liability.” That's what led to the original Price-Anderson Act. It's also what led to the situation where every insurance policy in the world, to my knowledge, contains the nuclear exclusion clause saying that homeowners are not covered in the event of radioactive contamination. That's a direct result of the studies carried out by the nuclear industry in 1957.
