The Fukushima clean-up team remains in the dark about the exact locations of 600 tons of melted radioactive fuel from three devastated nuclear reactors, the chief of decommissioning told ABC’s Foreign Correspondent program in an exclusive interview.
The company hopes to locate and start removing the missing fuel from 2021, the Tokyo Electric Power Company’s chief of decommissioning at Fukushima, Naohiro Masuda, revealed.
The fuel extraction technology is yet to be elaborated upon, he added.
Following the tsunami-caused 2011 meltdown at Fukushima Dai itchi nuclear power plant uranium fuel of three power generating reactors gained critical temperature and burnt through the respective reactor pressure vessels, concentrating somewhere on the lower levels of the station currently filled with water.
The melted nuclear fuel from Reactor 1 poured out completely, estimated 30 to 50 percent of fuel from Reactor 2 and 3 remained in the active zone, Masuda said.
The official estimates that approximately “200 tons of [nuclear fuel] debris lies within each unit,” which makes in total about 600 tons of melted fuel mixed up with metal construction elements, concrete and whatever else was down there.
