The study identified future potential electric generation capacity of 158 gigawatts for advanced coal, 78 gigawatts for water and dry-cooled concentrated solar energy and 515 gigawatts for large nuclear reactor plants.
The drywell is a large steel pressure vessel that looks like a giant upside-down pear and holds the reactor and primary pumps, and the wetwell is a large toroidal vessel that looks like a donut.
With plutonium no longer needed for use in the world's abandoned fast breeder reactor programmes and nuclear powers getting rid of their atomic weapons, large stockpiles of the highly toxic plutonium metal are starting to build up.
