August 16, 2012 (why did it take so long for the Mainichi to mention this leak?)
Tokyo Electric Power Co. on Tuesday morning discovered possibly highly radioactive water on the first floor of the No. 4 reactor turbine building at its disaster-crippled Fukushima No. 1 nuclear power plant.
The company believes the water leaked from a pipe that is transferring highly radioactive water from the basement of the No. 3 reactor's turbine building.
A TEPCO worker found the water on the floor of a power control room in the No. 4 reactor turbine building at 11:15 a.m. The company confirmed that the leak had stopped by about 1 p.m. after the radioactive water transfer was suspended at 12:20 p.m.
According to TEPCO, a puddle of water about one centimeter deep had collected on the floor of the 350-square-meter power control room. There was no water leak outside the room, the company added.
The water is estimated to contain tens of thousands of becquerels of radioactive cesium per cubic centimeter, according to the firm.
