Division Spotlight
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

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 pressure dependence of separation factors of the columns for H2-HT mixture was measured for practical design of "cryogenic-wall" thermal diffusion columns for tritium handling system. Experiments were performed with 1,020 mm-height column with a 4.8 mm-outer-radius tube heated by hot-water and a 11.5 mm-inner-radius tube cooled by liquid nitrogen. The maximum total separation factor was 12.7 at 80 kPa for H2-HT separation. By using another column with 9.53 mm-outer-radius tube heated by hot-water and a 14.2 mm-inner-radius tube, the separation factor was 64.4 at 144 kPa, and the separation will be larger at higher pressure.Comparison of numerical calculations of axial and radial two-dimensional flow and concentration distribution with experimental data revealed that our code could predict the pressure dependence of separation factor of the columns well.
