TEPCO ex-chair at time of Fukushima nuclear disaster dies at 84 while on trial over responsibility

Tokyo Electric Power Company Holdings' former chairperson, who led the emergency response after a meltdown at its Fukushima Daiichi nuclear plant and was accused of being responsible for failing to prevent the disaster as top management, has died, with his trials still pending. Tsunehisa Katsumata died on Oct. 21, TEPCO said Thursday, without providing further details including the cause of his death. Katsumata was TEPCO chair when Fukushima Daiichi was hit by a magnitude 9.0 earthquake and tsunami in March 2011 and suffered triple meltdowns.

A decade after Fukushima, Japan still struggles with its energy future

Ten years after an earthquake and tsunami sparked a crisis in the east of Japan, the country’s electricity generation profile has shifted in favour of fossil fuels. Will its net-zero emissions goal change that?

A robot begins removal of melted fuel from the Fukushima nuclear plant. It could take a century

A long robot entered a damaged reactor at Japan's Fukushima nuclear power plant on Tuesday, beginning a two-week, high-stakes mission to retrieve for the first time a tiny amount of melted fuel debris from the bottom. Specialists hope the robot will help them learn more about the status of the cores and the fuel debris. Here is an explanation of how the robot works, its mission, significance and what lies ahead as the most challenging phase of the reactor cleanup begins. What is the fuel debris?

A robot has begun a 2-week mission to retrieve melted fuel from the damaged Fukushima nuclear plant

An extendable robot began on Tuesday a two-week mission to retrieve the first sample of melted fuel debris from inside one of three damaged reactors at the Fukushima Daiichi nuclear power plant. Highly radioactive fuel and other materials in the reactors melted when a massive earthquake and tsunami in 2011 damaged the plant's cooling systems. The plant's operator, Tokyo Electric Power Company Holdings, has previously used small robots to examine the inside of the reactors, but this is the first time for it to collect a sample of the melted debris in what will mark the start of the most challenging part of the plant's decadeslong decommissioning.

A robot's attempt to get a sample of the melted fuel at Japan's damaged nuclear reactor is suspended

An attempt to use an extendable robot to remove a fragment of melted fuel from a wrecked reactor at Japan’s tsunami-hit Fukushima Daiichi nuclear power plant was suspended Thursday due to a technical issue. The collection of a tiny sample of the debris inside the Unit 2 reactor’s primary containment vessel would start the fuel debris removal phase, the most challenging part of the decades-long decommissioning of the plant where three reactors were destroyed in the March 11, 2011, magnitude 9.0 earthquake and tsunami disaster. The work was stopped when workers noticed that five 1.5-meter (5-foot) pipes used to maneuver the robot were placed in the wrong order and could not be corrected within the time limit for their radiation exposure, the plant operator Tokyo Electric Power Company Holdings said.

A robot will soon try to remove melted nuclear fuel from Japan's destroyed Fukushima reactor

The operator of Japan's destroyed Fukushima Daiichi nuclear power plant demonstrated Tuesday how a remote-controlled robot would retrieve tiny bits of melted fuel debris from one of three damaged reactors later this year for the first time since the 2011 meltdown. Tokyo Electric Power Company Holdings plans to deploy a “telesco-style” extendable pipe robot into Fukushima Daiichi No. 2 reactor to test the removal of debris from its primary containment vessel by October. During the demonstration at the Mitsubishi Heavy Industries' shipyard in Kobe, western Japan, where the robot has been developed, a device equipped with tongs slowly descended from the telescopic pipe to a heap of gravel and picked up a granule.
