• To prepare for extraction, personnel at the tritium extraction facility receive a cask of irradiated rods from the Tennessee Valley Authority. The cask can be seen from the top viewed through a room built in concrete. It has a shining steel surface and cylindrical shape. It appears to be at least three times as high as the operator. The person wears a yellow protective suit, orange helmet and gloves.

    Record Tritium Production for Nuclear Weapons

    In January 2026, the US National Nuclear Security Administration (NNSA) announced the achievement of a significant milestone in completing a record amount of tritium produced for nuclear weapons. Tritium is used in nuclear weapons to boost the yield of the fission material of the primary stage. A mixture of tritium and deuterium gas is injected into the pit just before the nuclear chain reaction starts. Fission energy causes tritium and deuterium to fuse and create additional neutrons. Due to its 12.3-year half-life, tritium decays radioactively at the rate of 5.5 percent each year and must be replenished periodically in the warhead’s reservoir. Therefore, tritium needs to be produced unless stocks…
