Next stage for robotic decontamination

13 June 2014

Two robots are cleaning up contamination inside Fukushima Daiichi 2. A new one is wiping down the walls while another continues to scrub the floor.
Although it suffered a core melt three years ago, unit 2 saw none of the hydrogen explosions that tore through other damaged reactors on the site. Its building is therefore relatively undamaged and well sealed, but this also means there is much contamination trapped inside that must be dealt with before workers can re-enter.
Since November last year a small robot dubbed the Raccoon has been systematically scrubbing and jet washing the floor of the plant's first level. On 9 June it was joined by a much larger sibling, a modified Husqvarna DX-140 from Sweden weighing almost one tonne.
