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.

Applicability of Li2O pebble type breeder has been investigated. Current experimental and analytical studies reveal that problems of thermal stress cracking and vaporization mass transfer can be resolved. Design feasibility studies of Li2O pebble type blanket have been performed for the FER and a power reactor. Results show that Li2O pebble breeder makes it possible to design blankets with high breeding ratio and high breeder integrity which can satisfy design requirements with some allowance for uncertainties or variations of parameters.
