Regulation around nuclear needs to be commensurate with actual risk, and it should be financed appropriately, with richer nations covering the costs for developing countries.

This is an interesting point, especially given the struggles that the developed nations have in getting such generation built within their own borders. But the idea of helping to finance climate solutions in developing nations is nothing new, so it makes sense it would extend here-- I just wonder how politically/popularly challenging doing so will be given the continued perception many outside the business continue to have with nuclear

Thanks for the history lesson.  But the article does not address any of the issues around nuclear energy.

In recovering from World War Two and its aftermath, the world lost confidence and demonised nuclear energy.

No, it was sometime later.  On the contrary, in recovering from World War Two the world embraced and worshipped the peacetime uses of nuclear fission.  In the process, the nuclear industry made many promises, none of which were kept. 

As for:

"...it should be financed appropriately, with richer nations covering the costs for developing countries."

We are seeing in Ukraine how nuclear power generation plants can be weaponized for the purpose of terrorizing a country and its neighbors.

Now, 77 years since World War Two, the world has found better alternatives.  There are still some niche uses for small fission reactors, in medicine, for example, as you say. And the new generation coming in the 2030´s may be useful. It is far too soon to say. And even nuclear fusion is still a worthy goal to pursue.  But for now and the next ten years or so, the only alternative to fossil fuels is the rapid development of renewables and storage.

This article calls for reviving the vision of nuclear, but then rejects the notion that other visions without nuclear are viable. The author goes back to that energy expert Karl Marx in 1867 to dismiss wind power. It's as though the author has not kept pace with the technological innovations over the last decade that have much diminished the need for baseload generation (and even made it detrimental.) These types of articles from those who reside in a past world are not helpful in finding solutions.
