New details have emerged of the grueling conditions workers at Japan's Fukushima Daiichi nuclear plant are still facing more than two weeks after the earthquake and tsunami first struck. Their shifts last three days and nights—during which they sleep anywhere they can find open space, including stairwells—until they get a 12 hour break before going back into the danger zone. Their food rations are minimal and they clean themselves with wet wipes since they have a limited supply of fresh water. The plant's safety inspector Kazuma Yokota spent five days with them last week and reported details of their conditions to CNN on Tuesday, saying they all seem exhausted and are constantly struggling to connect electrical cables and pump radioactive water out of the plant. Yokota said he hoped TEPCO would move current workers to another facility soon, or send in others from different plants.
