Nuclear Power Plant

, 2021
Fusion power plants will generate power by exploiting nuclear fusion. The most encouraging fusion reaction is the DT reaction since it has the most elevated cross-sections at least energies (Figure 1.) The first generation of fusion power plants will use deuterium and tritium as fusion fuels.
