Deuteriumtritium
Deuteriumtritium refers to the fusion reaction between the hydrogen isotopes deuterium (2H) and tritium (3H). The most studied form is D-T fusion, which produces a helium-4 nucleus (alpha particle) and a fast neutron: 2H + 3H → 4He + n. The total energy released per reaction is about 17.6 MeV, with the neutron carrying 14.1 MeV and the alpha particle about 3.5 MeV of kinetic energy. The high-energy neutron is a key consideration for reactor design, contributing to material heating and activation.
Deuterium is a stable, naturally occurring isotope of hydrogen, comprising about 0.015% of hydrogen in seawater.
D-T fusion is the leading candidate for practical controlled thermonuclear energy due to its relatively high
Safety and environmental aspects center on handling tritium, a weak beta emitter, and managing neutron-induced activation
