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 investigation aimed at identifying methods of flattening the power distribution in D-T blankets has been carried out. Three methods were identified which when used in conjunction produce power distributions which are significantly flatter than those produced by typical blankets. The peak-to-average power density ratio is reduced by over 50%, and the peak-to minimum power fall-off is reduced by a factor of five. Power flattened blankets achieve tritium breeding ratios and blanket multiplication which could be somewhat higher than those of typical blanket designs.
