Leaks of radioactive water have become more frequent at Japan's crippled nuclear power plant less than two months after it was declared basically stable.
The problem underlines the continuing challenges facing Tokyo Electric Power Co. as it attempts to keep the Fukushima Dai-ichi nuclear plant under control. A massive earthquake and tsunami badly damaged the plant last March, resulting in the melting of three reactor cores.
Workers spotted a leak Friday at a water reprocessing unit which released enough beta rays to cause radiation sickness, TEPCO spokesman Junichi Matsumoto said. He said no one was injured and the leak stopped after bolts were tightened on a tank. (AP)
