A robot has begun its second attempt to extract melted nuclear fuel from one of the reactors at the Fukushima Daiichi power plant in Japan, as part of a long and complex decommissioning effort following the 2011 nuclear disaster.
On Tuesday, Tokyo Electric Power Company (Tepco) launched the latest mission at the plant’s No 2 reactor, aiming to retrieve a fresh sample of radioactive debris from closer to the core.
