Setbacks mounted Wednesday in the crisis over Japan's tsunami-damaged nuclear facility, with nearby seawater testing at its highest radiation levels yet and the president of the plant operator checking into a hospital with hypertension.
Nearly three weeks after a March 11 tsunami engulfed the Fukushima Dai-ichi plant, knocking out power to the cooling system that keeps nuclear fuel rods from overheating, Tokyo Electric Power Co. is still struggling to bring the facility in northeastern Japan under control.
Radiation leaking from the plant has seeped into the soil and seawater nearby and made its way into produce, raw milk and even tap water as far as Tokyo, 140 miles (220 kilometers) to the south.
The stress of reining in Japan's worst crisis since World War II has taken its toll on TEPCO President Masataka Shimizu, who was sent to a hospital late Tuesday.
Shimizu, 66, has not been seen in public since a March 13 news conference in Tokyo, raising speculation that he had suffered a breakdown. For days, officials deflected questions about Shimizu's whereabouts, saying he was "resting" at company headquarters.
