>> A nuclear power plant's approximately twenty thousand safety components have a Rube Goldberg quality. Like dominoes, numerous pumps, valves, and switches must operate in the required sequence to simply pump cooling water or shut down the plant. There were innumerable unlikely combinations of failures that could cause an accident Query: Is anything this complex designed this way today, without actually running all its failure modes through risk analysis before actually building it?
