Japan has restored electricity to three of the damaged nuclear reactors at the Fukishima Daaichi plant, but it’s still not in the clear: Smoke was billowing once again from the No. 3 reactor, and the plant had to evacuate workers as it assessed the situation. At another reactor, workers discovered that crucial machinery needs repair—a process that could take two to three days. Meanwhile, iodine and cesium have turned up in Tokyo’s tap water, and the government has advised residents of a village 20 miles from the plant to quit drinking tap water after it was found to contain high levels of iodine. The government has halted shipments of spinach and milk in another part of the country due to large traces of iodine.
