Decommissioned Nuclear Power Plants in USA
Sorted by Mwe – Megawatts of Energy from largest to smallest
Updated 9-29-16

This table shows that as of this writing, SONGS, the decommissioned San Onofre Nuclear Generating Station is the largest privately owned beachfront nuclear waste dump in the USA.  The power plant  had three nuclear generators with a total capacity of 2,800 MWe, creating many millions of pounds of radioactive waste that’s toxic to humans for millions of years.  While the facility is  located approximately 500 feet from the Pacific Ocean, the actual waste or ISFSI (Independent Spent Fuel Installation) will be stored in steel canisters 108 feet from the beach at San Onofre State Park.
