Japan's Largest Nuclear Plant Stops Reactor Hours After Brief Restart

A reactor at Japan's Kashiwazaki-Kariwa plant—the world’s largest—was briefly restarted but shut down again hours later due to an issue with removing control rods; TEPCO said there was no radiation leak. The restart follows a history of safety and alarm-system problems since the 2011 Fukushima disaster, with a broader plan to reactivate some reactors slowly and decommission others amid ongoing public debate about nuclear power in Japan.

Japan pauses world's largest nuclear plant hours after restart

Japan suspended operations at the Kashiwazaki-Kariwa plant, the world's largest by capacity, just hours after restarting reactor six when an alarm sounded during start-up; Tepco says the reactor is stable with no radiological impact outside the plant and is investigating the cause. The seventh reactor is not expected to resume until 2030, and five other reactors could be decommissioned, leaving far less capacity than before Fukushima.

Japan restarts the world’s largest nuclear plant as safety doubts linger

Japan has restarted reactor 6 at the Kashiwazaki-Kariwa plant, the world's largest by capacity, marking the first restart since the 2011 Fukushima disaster; only one of seven reactors is back online for now, with the rest still uncertain and a 2030 timeline for the remaining unit. The move comes amid tightened safety standards and ongoing public distrust, as Japan pursues a longer-term push to revive nuclear power to meet energy self-sufficiency goals and 2040 targets, all while facing rising costs and protests.

Japan eyes restart of the world’s largest nuclear plant 15 years after Fukushima

As Japan marks 15 years since the Fukushima disaster, Tepco plans to restart reactor No. 6 at Kashiwazaki-Kariwa, the world’s largest nuclear plant in Niigata. The move, aimed at boosting energy security and emissions targets, faces fierce local opposition and safety concerns about evacuation capabilities for hundreds of thousands nearby. A delay due to a test alarm was followed by expectation it will go online soon, potentially adding about 2% to Tokyo-area electricity, but critics say safety and trust remain doubtful.

Fukushima Cleanup Delayed Again in Fuel Debris Removal

The full-scale removal of melted nuclear fuel debris at Fukushima Daiichi is delayed until at least 2037 due to extensive preparation needs, pushing back Japan's decommissioning timeline originally set for 2051, with experts estimating the process could take over a century.

Fukushima Nuclear Plant Delays Meltdown Debris Removal

The Fukushima Daiichi nuclear plant's full-scale removal of melted fuel debris has been delayed until 2037 or later due to extensive preparation needs, setting back Japan's decommissioning timeline originally targeted for 2051, with experts estimating the process could take over a century.

"Fukushima Daiichi Nuclear Plant Leaks Radioactive Water, Raising Contamination Risk"

Highly radioactive water leaked from a treatment machine at the Fukushima Daiichi nuclear power plant, but no radiation escaped the facility, and no one was injured. The leak, caused by valves left open during maintenance work, resulted in 6 tons of radioactive water seeping into the soil. Despite concerns over Tepco's controversial wastewater discharge project, radiation levels around the plant and in the environment remain unaffected. This incident follows a previous accidental leak at a separate treatment facility, highlighting ongoing challenges in managing the aftermath of the 2011 disaster.

"Japan Grapples with Nuclear Concerns and Missing Persons in Wake of New Year's Earthquake"

A significant earthquake on Japan's western coast has raised concerns about the safety of restarting nuclear power plants in a country frequently hit by natural disasters. The quake caused damage and power outages, and occurred shortly after a ban on the operation of Tokyo Electric's Kashiwazaki-Kariwa plant was lifted. Despite the government's shift towards reviving nuclear energy due to energy crises, public skepticism remains high, especially after the recent tremor caused water to spill from nuclear fuel pools, although radiation levels remained normal. The incident has affected the stock market and could influence Japan's energy policy and public sentiment towards nuclear power.

"Japan's Earthquake Aftermath: Nuclear Restart Dilemmas and Travel Advisory Updates"

A recent earthquake near Japan's western coast has raised concerns about the safety of restarting nuclear power plants in a country prone to natural disasters. The quake struck close to TEPCO's Kashiwazaki-Kariwa plant, which had just had an operational ban lifted, and caused water to spill from nuclear fuel pools, although radiation levels remained normal. The event has affected public sentiment and could influence government policy on nuclear energy, as Japan grapples with energy security and high prices. Despite initial market reactions, analysts do not foresee an immediate impact on LNG imports, but future disruptions could change this outlook.

"Reconsidering Fukushima's Wastewater Ocean Dumping After System Failure"

Japan's government and Tepco, the owner of the Fukushima-Daiichi nuclear plant, plan to pump 1.37 million tons of radioactive wastewater into the Pacific Ocean. However, their track record with wastewater management is poor, with their filtration system, ALPS, being a failure. The ALPS system has not effectively removed radioactive materials, and documents show that 84% of the water at Fukushima contains concentrations of radioactive materials higher than legal limits. Tepco plans to re-filter the wastewater, but this process leaves behind highly radioactive sludge. Concerns have been raised about the lack of transparency and the potential health risks associated with the ocean dumping.

Fukushima Plant Operator Confirms Radioactive Wastewater Release.

Tokyo Electric Power Holdings (TEPCO) has completed construction on all necessary infrastructure and equipment to discharge treated radioactive wastewater from the Fukushima Daiichi power plant into the ocean. The only barrier remaining is a final safety inspection from national regulators. If approved, TEPCO expects to begin discharging the wastewater this summer. The company has been treating the water to minimize its radioactivity, but not all harmful compounds can be removed. Critics remain skeptical of the plan, citing environmental concerns and potential long-term marine health impacts.
