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.

The energy spectra and angular distributions of the proton emission from the 93Nb(n,xp) reaction are measured by means of the multitelescope system at the University of Science and Technology of China. The total proton production cross sections are in fair agreement with the results obtained by other groups. The energy spectrum is explained well by the sum of the spectra calculated on the basis of the pre-equilibrium and Hauser-Feshbach theories. There are deviations from a previous measurement of the high-energy end of the angle-integrated proton spectrum. The angular distribution, which shows a strongly energy-dependent forward-backward asymmetry, is in fair agreement with the Kalbach-Mann phenomenological model.
