Radioactive leaks shuts reactor

A radioactive water leak forced officials to shut down a nuclear reactor at a troubled power plant in Japan today, just one day after it was brought on line after similar problems last year triggered a six-month hiatus.

About half a gallon of cooling water had dripped from a pipe seam on to the floor in the No. 2 reactor before the problem was discovered this morning, said Eichi Miyata, a spokesman at the Chubu Electric Power Co.
