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.

Migration of I52Eu(III), 235Np(V), 237Pu(IV), 241Am(III), 99Tc(VII), and 99Tc(IV) was studied in natural fissures oriented parallel to the axis of granitic drill cores. A pulse of radionuclide solution was injected at one end of the fissure and the temporal change in radionuclide concentration of the effluent measured. At the end of each experiment the fissure was opened and the radionuclide distribution on the fissure surfaces measured. The radionuclide distribution ratios Ra, calculated from the measured retardation, correlate well to published distribution coefficients Kd. The increase in retardation of 235Np with increasing pH in the pH range 6 to 9 is in accordance with the hydrolytic equilibrium NpO2+ + OH‾ ⇄ NpO2(OH). Reduction of Tc(VII) to Tc(IV) resulted in a marked increase in retardation.
