Bruce nuclear power plant in Canada is the largest operating nuclear plant on record, with 8 units and 6.9 GW gross. Ranked by combined operating capacity at one site.

A "plant" is a site: several reactor units sharing one location, sometimes built decades apart. Ranked by combined operating capacity; a unit under construction at the same site adds to its future total, shown separately, not to the rank.
