(Dow Jones) – Giant polyester covers will soon be placed around the damaged reactor buildings at Japan’s Fukushima nuclear complex to help contain the release of radioactive substances into the atmosphere, the plant operator said Friday.
Tokyo Electric Power Co. (TEPCO) will install the first cover at the No. 1 reactor, the focus of recent stabilization efforts, starting next month.
Workers will erect a steel framework and place a giant polyester tent-like cover around the reactor building. Similar covers will be placed around units No. 3 and 4. The work is expected to be completed by the end of the year.
A series of hydrogen explosions blew off the roofs and upper walls of the three reactors in the days after the March 11 earthquake and tsunami knocked out their cooling systems, triggering the overheating of the reactors.
