An accident spreading hazardous substances over a large geographical area that are difficult to contain (or waste of this type) is unique to nuclear power; no renewable energy source poses such a threat.

Another problem is the urgency (due to the impacts) combined with the difficulty of modifying power plants as required by "lessons learned," in other words, bug fixes. Modifying or repairing solar panels or wind turbines is easier than working on a reactor and results in a smaller reduction in the plant's output. The effects of this are significant.

The number of victims (and more generally, the health impacts) of nuclear power depends on the method of analysis, which is controversial. This is true for Chernobyl and Fukushima, where the evacuation triggered by the nuclear accident officially caused 2,202 deaths (2019 count), and 2,313 according to the International Nuclear Association.

Even the maximum potential impact of an accident is debated.

The full impact of nuclear power will at best only be known after all dismantling is complete and the last cold waste is disposed of (before this deadline any mishap or stray waste can be costly), in a few thousand years.

renewables are still made from different substances, one of which is copper. One byproduct of copper is extremely toxic- arsenic, and it's spills are not that different in terms of dangers. That's the point. For nuclear at least, over time decay happens, esp for most dangerous isotopes, but for chemical waste - it's forever.

Nuclear still has higher capacity factor than any VRE.

Evacuation numbers for Fukushima are accounted in the stat. But it's also worth mentioning Japanese govt acknowledged most of the deaths are caused by extreme evacuation measures that werent needed, but govt ignored the data it had to enforce them. The panic against nuclear caused them, not radiation.
