WebNov 23, 2024 · Tritium is a dominant consideration in the development and operation of fusion systems for several key reasons. Although deuterium is naturally abundant in Earth's oceans, tritium is rare in nature because it is radioactive with a relatively short half-life of 12.32 years. Tritium can be generated by interaction of neutrons and lithium.
