DTRA’s advancements in nuclear and radiological detection
A new, more complex nuclear age has begun. Echoing the tensions of the Cold War amid rapidly evolving nuclear and radiological threats, preparedness in the modern age is a contest of scientific innovation. The Research and Development Directorate (RD) at the Defense Threat Reduction Agency (DTRA) is charged with winning this contest.

Two processes that use metal hydrides for tritium handling have been installed in the Savannah River Site tritium facilities and have been used in routine tritium processing operations for nearly the past 3 years. These processes represent significant demonstrations of metal hydride technology for pumping, purification (inert gas separation), storage, and compression of tritium. Pumping and purification are demonstrated with a pump/purifier that uses palladium supported on kieselguhr as the hydrogen isotope-absorbing material. Storage and compression are demonstrated in a tritium loading facility that uses LaNi4.15Al0.85 beds for tritium storage, and LaNi4.7Al0.3 and Ca0.2Mm0.8Ni5(Mm-Mischmetal) beds for tritium compression. Operating data collected during routine operation of the pump/purifier and the loading facility are presented and discussed.
