Division Spotlight
Fusion Energy
This division promotes the development and timely introduction of fusion energy as a sustainable energy source with favorable economic, environmental, and safety attributes. The division cooperates with other organizations on common issues of multidisciplinary fusion science and technology, conducts professional meetings, and disseminates technical information in support of these goals. Members focus on the assessment and resolution of critical developmental issues for practical fusion energy applications.

Proving DRACO will deliver
The United States is now closer than it has been in over five decades to launching the first nuclear thermal rocket into space, thanks to DRACO—the Demonstration Rocket for Agile Cislunar Orbit.

Four detection probes were designed with the PTA code package and fabricated to study energy deposition, temperature rise, and damage to plasma facing components from runaway electrons in the Advanced Toroidal Facility, Oak Ridge National Laboratory. The PTA code package is a unique application of PATRAN, the Integrated TIGER Series, and ABAQUS for modeling high energy electron impact on magnetic fusion components and materials. Two of the probes were made of stainless steel, one of graphite, and one of molybdenum. They were inserted one at a time on the magnetic axis of ATF during field ramps. Each probe had two thermocouples to measure temperature increases. One of the stainless steel probes had activation foils to detect photonuclear reactions. Analysis of the experiment concluded that runaways on the order of 10 MeV exist in ATF. Damage to the materials was in the form of melting and ablation. The graphite probe survived with less damage than the other probes.
