China has the newest plants in the world: https://www.iea.org/data-and-statistics/charts/age-profile-o...

We don't know how they'll perform as they age. If we calculated quality as you suggest, they would probably win.. but we would expect brand new plants to have fewer issues than 30 year old plants.

That's a strange expectation to have. Ever heard of the bathtub curve ?

In your formula, where do you envision the number of incidents being derived from?

China excels at hiding important information from public view, so I would take their data, and data indirectly sourced from them, with a grain of salt. And oh, by the way, one could say the same about the nuclear industry and its captured regulatory bodies in general as well.

That is true, which is why I specifically mentioned "severe" incidents - even if less severe stuff happens and is hushed up, it's impossible to keep radioactive particles blowing across the globe quiet, so we'd surely know of those.

Wouldn't you want to normalize by Joules produced instead of by reactor days?
