Deuterium-Tritium Fusion

2H + 3H → 4He + 1n

Tổng quan

Deuterium and tritium fuse at temperatures exceeding 100 million degrees to form helium-4 and a neutron, releasing 17.6 MeV of energy. This is the most feasible fusion reaction for power generation because it has the lowest ignition temperature and highest cross-section. The neutron carries 80% of the energy.

Ví dụ thực tế

The sun's energy comes from fusion reactions, though it primarily uses the proton-proton chain rather than D-T fusion.

Tầm quan trọng công nghiệp

D-T fusion is the basis for ITER and most fusion power research programs. Commercial fusion would provide virtually unlimited clean energy from seawater deuterium.
