Tepco tries to plug holes in roofs as typhoon approaches Fukushima Daiichi

Nikkei.com reports that Tokyo Electric Power Company (Tepco) is welding steel plates onto gaping holes on the roof of its damaged Unit 3 turbine hall at Fukushima Daiichi nuclear power plant, in order to prevent rainwater from spreading radioactive contamination within as a typhoon approaches. In addition, Tepco plans in the coming weeks to restore cooling water systems at Fukushima Daiichi's Unit 1 and Unit 1 pools for storage of high-level radioactive waste. Ever since March 11th, Tepco and Japanese government (police, fire, military) agencies have employed various ad hoc means of maintaining water within the boiling pools, from helicopter drops to fire trucks, concrete trucks, and even water cannons designed for crowd control.

Bloomberg also reported on the work to install the rain cover against the typhoon, as well as an update on the general situation at Fukushima Daiichi.
