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.

As part of the GA-funded TFCX proposal effort, a method was developed and implemented to make fast, repetitive calculations of fusion reactor shutdown dose rates for several operating and shutdown times. The ONEDANT discrete ordinates code is used as the transport code in this procedure. Examples of parametric study results using this method are given. The method is currently being used in tokamak ignition studies at GA.
