Division Spotlight
Reactor Physics
The division's objectives are to promote the advancement of knowledge and understanding of the fundamental physical phenomena characterizing nuclear reactors and other nuclear systems. The division encourages research and disseminates information through meetings and publications. Areas of technical interest include nuclear data, particle interactions and transport, reactor and nuclear systems analysis, methods, design, validation and operating experience and standards. The Wigner Award heads the awards program.

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.

The Texas fusion ignition experiment (IGNITEX) device is a 20 T single turn coil tokamak designed to produce and control an ignited plasma using ohmic heating alone. As a baseline design, IGNITEX has a 1.5 m major radius and operates at a toroidal field (TF) of 20 T on-axis. The small version of IGNITEX (R = 1.2 m) represents the smallest, low cost experiment that can produce fusion ignition under the saturated Neo-Alcator energy confinement scaling. The large version of IGNITEX (R = 2.1 m) represents the smallest experiment that can produce fusion ignition using the most pessimistic extrapolation of the Goldston scaling in L-mode. The Ignition Technology Demonstration (ITD) program was initiated to design, build, and test the operation of a single turn, 20 T, TF coil powered by an existing 9 MA, HPG power supply system. The ITD TF coil is a 0.06 scale of the IGNITEX and is now operating at the Center for Electromechanics at The University of Texas at Austin (CEM-UT). Data from the ITD experiment is used to confirm the complex computer model utilized for the IGNITEX design and analysis. In this paper, feasibility of the TF magnets is evaluated based on the electromechanical and thermomechanical considerations.
