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.

The recently completed Tokamak Fusion Core Experiment (TFCX) design project investigated potential “next generation” tokamak concepts. An important early development of the design was the incorporation of remote maintainability. Early coordination and incorporation of maintenance aspects to the design of the device and facilities will ensure that the machine can ultimately be maintained and repaired efficiently and cost effectively. A rigorously formatted engineering trade study was performed to determine the preferred configuration for the TFCX reactor based primarily on maintenance requirements. The study indicates a preferred design with an external vacuum vessel and torodial field coils that can be removed by simple radial motion. The trade study is presented and the preferred TFCX configuration is described.
