TEPCO has released multiple videos showing two PackBots navigating inside Fukushima reactors. It comes as the 20-kilometre evacuation area around Japan’s paralysed nuclear complex, has become an official no-go zone. The announcement comes after police found more than 60 families still living within the contaminated area. The plant, crippled by both the earthquake and tsumani, has been hit by a series of explosions and has leaked radiation into the air, ground and sea. Although people had been urged to leave the area after the March 11th disaster, the order was not enforced by law.
