Mid-and-Long-Term Roadmap Towards Decommissioning of the Fukushima Daiichi Nuclear Power Station
Council for the Decommissioning of TEPCO's Fukushima Daiichi Nuclear Power Plant
The committee for measures to decommission the TEPCO Fukushima Daiichi Nuclear Power Station changed from the "Working Council" to the "Council for the Decommissioning of TEPCO's Fukushima Daiichi Nuclear Power Plant" in January 2013. (Reports prior to January 2013 are published in "Working Council".)
