The huge disaster in Japan has ruined parts of the nation's electrical system, notably the six Fukushima Daiichi reactors that remain shut down. As a result, the country's utilities can't generate enough power to meet demand, so they are using rolling blackouts to give some power to everyone for some portion of each day.

Prime Minister Naoto Kan, making his first public statement on the crisis in a week, said the situation at the Fukushima nuclear complex north of Tokyo was "nowhere near the point" of being resolved.

On December 1, 1969, Jersey Central Power & Light initiated fission in the fuel rods of the nation's first boiling-water nuclear reactor--one of 31 ultimately built in the U.S. The first "turnkey" plant, Oyster Creek nuclear generating station in New Jersey was sold for less than $100 million in 1964--a price well below what it would ultimately cost to build the reactor. The point was to prove that a nuclear power facility could be built as cheaply as a coal-fired power plant, and the key to that was a smaller safety system
