Deuterium-Deuterium Fusion

2H + 2H → 3He + 1n

अवलोकन

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.

रोजमर्रा का उदाहरण

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

औद्योगिक महत्व

D-D fusion is a long-term goal for fusion energy because deuterium is virtually unlimited. Current research focuses on D-T as an intermediate step.
