Arsenic: this only plays during mining (recycling is OK), and efficient measures are already in place (where and when was it a problem, and at which extent?) > capacity factor So what? Capacity factor (or another similar quantity such as physical efficiency, operating life, etc.) is a salient criterion in the case of equipment consuming materials or fuel without recycling them, or producing waste in quantity or in the long term that is dangerous... therefore does not concern nuclear power but hardly concerns renewables. A low yield makes deployment more expensive but, considered alone, is not prohibitive: a mix of renewables producing adequately (quantity, permanence, impacts, total cost including recycling, etc.) is a good solution whatever its yield. > most of the deaths are caused by extreme evacuation measures that werent needed This is disputed and the real amplitude of the threat was not known during the nuclear accident. The tiny evacuation ordered was minimally cautious as experts predicted, during the accident, that the worst cast would imply evacuating up to 50 millions persons: https://en.wikipedia.org/wiki/Naoto_Kan#In_media https://en.wikipedia.org/wiki/Naoto_Kan#In_media

There are some very recent arsenic spills events in copper mines... Nuclear fuel can be recycled, just like renewables. It's mostly not done because it's cheaper not to, just like in renewables The danger was known based on multiple data points. Japanese govt ignored them. And they acknowledged evacuation was not necessary in the way it was implemented Capacity factor is important to understand how much firming you need

  > There are some very recent arsenic spills Indeed, but nothing comparable to the spills at Chernobyl or Fukushima. > Nuclear fuel can be recycled Only once, and France, an industrial leader in this area, only manages to recycle 10% of its reactor fuel this way. > It's mostly not done because it's cheaper not to, just like in renewables No, that's completely false. Closing the fuel cycle was considered the Holy Grail as early as the 1950s, because everyone knew that uranium deposits would greatly limit the expansion of nuclear power. The industrialization of reactors of the most promising architecture (fast neutron-breeders, sodium-cooled) as well as others, attempted at great length and expense in many countries, failed everywhere ( https://en.wikipedia.org/wiki/Breeder_reactor#Notable_reactors https://en.wikipedia.org/wiki/Breeder_reactor#Notable_reacto... ), there is no ready-to-deploy model of such reactor, and this approach has been virtually abandoned, replaced by the pursuit of fusion. > The danger was known based on multiple data points Before the major nuclear accident at Fukushima, the formulas for calculating seismic risk (the tsunami was triggered by an earthquake) were incorrect because they neglected very old earthquakes. The cause was an inability to properly assess the risk. This inability was not universal, as some (for example, Y. Hirai in the case of the Onagawa nuclear power plant, which was closer to the earthquake's epicenter and withstood the earthquake: https://en.wikipedia.org/wiki/Onagawa_Nuclear_Power_Plant#2011_T%C5%8Dhoku_earthquake https://en.wikipedia.org/wiki/Onagawa_Nuclear_Power_Plant#20...) did take the necessary precautions. > They acknowledged evacuation was not necessary in the way it was implemented. Arms-chair tacticians are verbose after the fact, but nowhere to be found when the problem was an ongoing challenge and experts described the worst-case scenario. The testimony of the prime minister at the time, referenced above, is perfectly clear. > Capacity factor is important to understand how much firming you need. No value is prohibitive, as there are many other pertinent parameters.
