Target is to finish cleanup at site within within 30 to 40 years of the 2011 accident The government of Japan and Tokyo Electric Power Company plan to start removing melted fuel from Unit 2 at the Fukushima-Daiichi nuclear power station in 2021, according to the latest decommissioning plan.
The draft plan, revised for the fifth time and released on 2 November, said Unit 2 was picked first for the removal process because it is safer than Units 1 and 3, which also melted down after the March 2011 Great East Japan Earthquake and tsunami.
The revised draft plan will be finalised after residents and experts give their opinions to a committee of cabinet ministers related to the decommissioning and contaminated water problems at the plant.
Investigations have confirmed that debris believed to be melted nuclear fuel at the bottom of the containment vessel in the Unit 2 reactor building can be lifted by a remote-control device.

Tepco president Tomoaki Kobayakawa mentioned for the first time the possibility of decommissioning some or all of Units 1 to 5 at Kashiwazaki Kariwa, the world’s biggest commercial nuclear station by capacity.
Media reports in Japan said Kashiwazaki city mayor Masahiro Sakurai had originally asked Tepco to shut all of the older units at Kashiwazaki Kariwa – Units 1 to 5 – in return for endorsing the restart of the two newer reactors, Units 6 and 7.
Units 1 to 5, all 1,067 boiling water reactor units, began commercial operation between 1985 and 1990. Units 6 and 7 are 1,315 MW advanced boiling water reactor units that began commercial operation in 1996 and 1997.
