A new tritium laboratory and process systems have been completed at Los Alamos National Laboratory (LANL). The highly automated Weapons Engineering Tritium Facility (WETF), containing approximately 861 m2 (8,000 sq ft) of floor space, replaces an aging tritium laboratory. The new facility provides improved protection to personnel involved in tritium handling operations, reduced routine releases of tritium to the atmosphere, and reduced potential for a major tritium release that might result from an accident or a human error.
