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.

An assessment is made of the gamma radiation hazards likely to be found near a fusion reactor which employs a vanadium alloy for the blanket and first wall structure, ferritic-steel HT9 for the remainder of the loop and molten salt FLiBe as coolant/tritium breeding fluid. Since the radiation levels near the primary loop components are found to be less than 100 mR/hr 3–5 days after shutdown after three years of continuous full power operation, limited hands-on maintenance is conceivable. The very short half-lives of the predominant corrosion products make this result possible and make such a system very attractive.
