ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

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.

Recently, oscillating high-speed slab jets, or liquid sheets, have been proposed for shielding the first walls of inertial fusion energy (IFE) reactor chambers from damaging X-rays, neutrons and ions. The near-field dynamics of obliquely oscillating turbulent liquid sheets were investigated in scaled experiments. Results are presented for sheets at Reynolds numbers up to 37000 oscillated along various directions at frequencies from 0 to 11 Hz and amplitudes up to half the nozzle thickness (0.5δ). Data on maximum trajectories of oscillating sheets and growth rates of stationary sheets are presented for distances up to 90δ downstream of the nozzle exit. A model for predicting the maximum trajectory is presented. The bulk of the experimental data are in reasonable agreement with this model. These results can be used to provide design guidelines for thick liquid protection.
