> IT IS REPLACING. If you had nuclear plants that worked fine (highest CF globally probably after US), some even not reaching 40y (when most are extended to 60-80y) and you retire them instead of retiring coal, it means coal replaced nuclear.

No it doesn't mean that at all. In particular, in Germany, the total coal generation went down, so it couldn't have replaced anything. What replaced nuclear in Germany was renewables and gas.

Consider your logic: if we had nuclear and retired it instead of shutting down renewables, does that (by your logic) mean renewables replaced nuclear? If not, why not? The structure of your argument seems to be privileging coal over other sources on the German grid.
