Electricity production from nuclear reactors shut down following the Fukushima accident (more than half of which were fully operational) was replaced by fossil fuels, mainly coal and gas.  This fossil fuel-generated electricity led to a 36% increase in CO2 emissions per kilowatt hour between 2010 and their peak in 2013. These mainly imported fossil fuels … Continued

Following the accident, damage to the structures led to water infiltration (rain, underground, etc.) into buildings. This water, in contact with debris and the core, is loaded with radioactive elements. This water, pumped, collected, decontaminated, and then stored in large tanks on the plant site, reached its maximum volume in early 2023, i.e. 1.3 million m³ … Continued

The Fukushima-Daiichi nuclear accident caused 3.5 PBq* of Cesium-137 and 134 to be released into the Pacific Ocean, leading to a temporary increase in radioactivity of the water near the plant. Releases into the atmosphere also led to an increase in radioactivity in the air. The limited duration of these releases, the dilution of the Cesium … Continued

A gross exaggeration This statement grossly exaggerates the consequences of the accident. While the 1979 Three Mile Island accident in the United States was a serious event and raised concerns about the safety of nuclear reactors, it did not result in any major environmental or health consequences. The accident was classified (retroactively) at level 5 … Continued

A promising energy source This statement raises some interesting questions, but it suggests that nuclear fusion will be rapidly available and commercially viable. Nuclear fusion is a promising technology that, if successful, could offer an almost unlimited, clean, and safe source of energy [1]. However, nuclear fusion is still in its infancy and its large-scale … Continued
