Deuterium-Deuterium Fusion

2H + 2H → 3He + 1n

Descripción general

Two deuterium nuclei fuse to produce helium-3 and a neutron, releasing 3.27 MeV. An alternative D-D reaction produces tritium and a proton. D-D fusion requires higher temperatures than D-T fusion (about 400 million K) but uses only deuterium, which is abundant in seawater.

Ejemplo cotidiano

Deuterium in one gallon of seawater contains enough fusion fuel energy to equal 300 gallons of gasoline.

Importancia industrial

La fusión D-D es un objetivo a largo plazo para la energía de fusión porque el deuterio es prácticamente inagotable. La investigación actual se centra en la fusión D-T como paso previo hacia reactores D-D.
