Even after the Fukushima No. 1 crisis in March 2011 forced Japan to rethink its use of nuclear energy, the resource-scarce nation had hoped nuclear power would still serve it well.
Nearly eight years have passed since the severe accident at Tokyo Electric Power Company Holdings, Inc.’s Fukushima No. 1 nuclear power plant in March 2011. Based on the lessons from the accident, new safety standards for nuclear power plants were implemented in July 2013, and 15 nuclear reactors at eight power plants cleared the new standards.
Tokyo Electric Power Company Holdings, Inc. said Wednesday that it has for the first time made contact with deposits believed to be nuclear fuel debris — a mixture of melted nuclear fuel and parts of the reactor — inside the containment vessel of the No. 2 reactor at the Fukushima No. 1 nuclear power plant.
The operator of the disaster-hit Fukushima No. 1 nuclear power plant said Wednesday it has completed its first attempt to use a remote-controlled probe to manipulate melted fuel accumulating at the bottom of one of the crippled reactors.
Tokyo Electric Power Co. Holdings will use a survey robot to make direct contact with the radioactive fuel at its Fukushima Daiichi nuclear power plant this week, the first such attempt since the meltdown eight years ago in March.
Kyushu Electric Power Co. said Wednesday it has decided to scrap its aging No. 2 reactor at Genkai nuclear plant in the southwestern Japan prefecture of Saga.
The owner of the wrecked Fukushima No. 1 power plant is trying this week to touch melted fuel at the bottom of the plant for the first time since the disaster almost eight years ago, a tiny but key step toward retrieving the radioactive material amid a ¥21.5 trillion ($195 billion) cleanup effort.
Radioactive cesium exceeding the state limit has been detected in fish caught off Fukushima Prefecture for the first time in about four years, the prefecture’s fisheries cooperatives association has said.
Toshiba Corp. unveiled a remote-controlled robot with tongs on Monday that it hopes will be able to probe the inside of one of the three damaged reactors at the tsunami-hit Fukushima nuclear plant and grip chunks of highly radioactive melted fuel.
The concentration of radioactive cesium-137, which was spread about following the accident at Tokyo Electric Power Company Holdings Inc.’s Fukushima No. 1 nuclear power plant, has been rapidly decreasing in river waters in municipalities near the facility in Fukushima Prefecture, according to a survey by the Japan Atomic Energy Agency.
