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.

Fusion power stations using the deuterium-tritium reaction will have substantial inventories of tritium in the oxide, molecular, and solid (metal hydride) forms. A new Canadian fusion engineering project based on Canada deuterium uranium (CANDU) operating experience with deuterium and tritium and plans to extract and concentrate tritium from Ontario Hydro's reactors is described. The aims of this project are to contribute to the international fusion effort by extracting useful existing information and translating that experience for application to fusion, and acting as a technology development agency by funding further research and development (R&D) in project mandate areas. Project R&D activities in each of the following five mandate areas are described: 1. Fuel Systems and Tritium Management Programs 2. Materials Technology Programs 3. Equipment Development Programs (including remote operations) 4. Health and Environmental Program 5. Breeding Blanket Technology Program. Also summarized are health and safety experiences with tritium in the CANDU program and plans for large-scale tritium removal from heavy water moderator and coolant systems.
