didn't know about this one, looks nice but complicated.

Note: if you want to see individual stations, you can disable clustering on the map I've made on the top right corner there's a control for disabling clustering.

maybe I should make clustering disabled by default?

All OpenStreetMap - nuclear:

And you can add an extra osm link / Wikidata link for any individual Nuclear Plants:

example:

Nice, thanks for the ideas and links! Might add this data to the map in the future, hopefully will find a way to do so in a user-friendly way without cluttering the ui.
