Energy that originates from the splitting of uranium atoms in a process called fission. This is distinct from a process called fusion where energy is released when atomic nuclei combine or fuse.

Groundbreaking Tokamak Fusion Test Reactor is designated a Nuclear Historic Landmark

The American Nuclear Society (ANS) has bestowed its distinguished Nuclear Historic Landmark designation on the pioneering Tokamak Fusion Test Reactor (TFTR) that ran from 1982 to 1997 at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory. The groundbreaking facility laid the foundation for future fusion (link is external) power plants and set world records for fusion power (10.7 million watts) in 1994 and total fusion energy production (1,500 million joules) from 1993 to 1997.

Researchers find unexpected electrical current that could stabilize fusion reactions

Electric current is everywhere, from powering homes to controlling the plasma that fuels fusion reactions to possibly giving rise to vast cosmic magnetic fields. Now, scientists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have found that electrical currents can form in ways not known before.

Permanent magnets far stronger than those on refrigerator doors could be a solution for delivering fusion energy

Permanent magnets akin to those used on refrigerators could speed the development of fusion energy – the same energy produced by the sun and stars.

In principle, such magnets can greatly simplify the design and production of twisty fusion facilities called stellarators, according to scientists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) and the Max Planck Institute for Plasma Physics in Greifswald, Germany. PPPL founder Lyman Spitzer Jr. invented the stellarator in the early 1950s.
