A fresh video analysis by the operator of the Fukushima Daiichi nuclear power plant shows that molten fuel at the No.2 reactor may have fallen along several paths. The unit is one of the 3 reactors that experienced a meltdown in 2011.

The footage shows all of the vessel’s bottom covered with what looks like pebbles and clay. A roughly 70-centimeter-high pile of such materials is located near where part of the fuel casing was spotted in the January probe.
Another heap is close to a pillar-like structure at the bottom.
The utility says the materials may be fuel debris, which is a mixture of molten nuclear fuel and structural parts.
The firm also released a 3-dimensional video that reconstructs the interior of the containment vessel of the No.3 reactor. The unit also suffered from a meltdown.
The footage shows a mound of materials near the center of the vessel’s bottom. The company says it may have emerged after fuel debris fell onto structural parts that had already dropped there during the 2011 accident.

The company is seeking to remove the molten fuel as part of its effort to decommission the plant.
