A combination of two methods should be used for the full-fledged removal of radioactive fuel debris from the Fukushima No. 1 nuclear power plant, Nuclear Damage Compensation and Decommissioning Facilitation has said.
The government-backed corporation, which supports the decommissioning of the nuclear plant operated by Tokyo Electric Power Company Holdings, on Friday proposed a combination of removing debris exposed in the air and solidifying debris using a filler.
