(Newser) – TEPCO is constructing an airtight polyester tent measuring 177 feet tall and 154 feet in length to cover one of the worst-hit reactors at the Fukushima Dai-ichi nuclear power plant, hoping the tent will stop leaked radioactive materials from spreading and prevent possible future leaks, reports the AP. Unsafe radiation levels had prevented workers from beginning work on the tent over the No. 1 reactor until now. It's expected to be finished by the end of September, and if it works as advertised, TEPCO officials say they will put up more such tents over other reactors.
