Britain's nuclear-rated facilities are described as extending beyond its submarine-building yard. Plymouth and Southampton are tentatively named, but no definitive list or count is established.

Earlier consideration of nuclear-powered surface ships also encouraged investment in facilities, although those surface-ship plans did not proceed.
