High Quality Content by WIKIPEDIA articles! International experts have said that a workforce in the hundreds or even thousands would take years or decades to clean up Japan`s Fukushima Daiichi nuclear disaster. On 10 April 2011, Tokyo Electric Power Company (TEPCO) began using remote-controlled, unmanned heavy equipment to remove debris from around nuclear reactors 1–4. TEPCO announced on 17 April that it expected to have the automated cooling systems restored in the damaged reactors in about three months and have the reactors put into cold shutdown status in six months. TEPCO plans to largely empty the basements of the turbine and reactor buildings of units 1-3 of contaminated water by the end of 2011. This will allow workers access to the crucial basement areas of both the turbine and reactor buildings.
