Despite more than six years having passed since the 2011 Fukushima nuclear meltdown disaster, workers are still struggling to clean up the Fukushima Daiichi power plant.

The radiation level has drastically fallen at most parts of the premises as a result of a containment project, but the operator Tokyo Electric Power Company Holdings Inc., better known as TEPCO, sees no clear path to decommissioning the facility as it still cannot find a way to approach melted fuel assemblies inside the devastated reactor buildings.
