– Rain increases contaminated water at plant (NHK, July 21, 2011):
Heavy rain brought by a tropical storm has increased the level of radioactive contaminated water at the basements of the crippled Fukushima Daiichi nuclear power plant.
Typhoon Ma-on moved east off the southern coast of Japan’s main island of Honshu. 115 millimeters of precipitation was recorded in Namie Town, north of the plant, between Tuesday and Thursday.
Rain has been gathering in the buildings housing the reactors because the roofs were severely damaged by hydrogen explosions that occurred after the initial March 11th disaster.
Tokyo Electric Power Company or TEPCO, the plant’s operator, says that at 7 AM local time on Thursday, the level of contaminated water pooled at the basement of the building of the No. 1 reactor was 44 centimeters up from the previous day.
Officials at the utility say that there is no immediate danger of the contaminated water spilling out.
But it is likely that the level of water will continue to rise for the time being. TEPCO says they are monitoring the situation.
