Tokyo Electric Power Company has sent its swimming robot into the remains of the Fukushima Daiichi power plant for a second time, in a bid to assess the damage to the three reactors. The robot has found large deposits of potential melted nuclear fuel, some one metre deep, inside "the pedestal", a structure that sits beneath the reactor core in the plant's primary containment vessel. The deposits, which are mixed in with broken reactor debris, are now submerged in highly radioactive water.
Tokyo Electric Power Company has sent its swimming robot into the remains of the Fukushima Daiichi power plant for a second time, in a bid to assess the damage to the three reactors. The robot has found large deposits of potential melted nuclear fuel, some as much as a metre deep, inside "the pedestal", a structure that sits beneath the reactor core in the plant's primary containment vessel. The deposits, which are mixed in with broken reactor debris, are now submerged in highly radioactive water.
