At least according to this it’s ~8% of the state’s electrical capacity all by it’s lonesome which doesn’t seem too bad. By the stats on it’s own wiki it’s pretty active.

I’ve heard there’s another reactor in the Willapa Hills that was constructed but never activated. Like some ghost story it still sits, unused, to this day.

Bangor got nuclear sub fleet, but the only functional reactor is the Hanford site in Richmond on the Columbia, as far as I know. Satsop site was cancelled with all the other reactors in Richmond.
