 Tritium Systems Test Assembly

The Tritium Systems Test Assembly (TSTA) is a facility associated with the development and testing of systems designed to produce and manage tritium, which is a key isotope used in nuclear fusion and in the production of nuclear weapons. The TSTA was part of the U.S. Department of Energy's efforts to ensure a reliable supply of tritium, particularly for the purposes of maintaining the U.S. nuclear stockpile.
