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
Operations & Power
Members focus on the dissemination of knowledge and information in the area of power reactors with particular application to the production of electric power and process heat. The division sponsors meetings on the coverage of applied nuclear science and engineering as related to power plants, non-power reactors, and other nuclear facilities. It encourages and assists with the dissemination of knowledge pertinent to the safe and efficient operation of nuclear facilities through professional staff development, information exchange, and supporting the generation of viable solutions to current issues.

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.

Reactions of protons induced on 208Pb and 209Bi, the important target materials in accelerator- driven systems, are studied. First, a set of proton optical model potential parameters for heavy elements is obtained up to 500 MeV. Theoretical total reaction cross sections and elastic scattering angular distributions determined by this set of optical model parameters reproduce the experimental data well. Second, several nuclear reaction models (optical model, intranuclear cascade mechanism for nucleon emission, preequilibrium theory based on the exciton model, evaporation model, and the direct reaction theory) are extended for medium energy, and the various reactions of p + 208Pb and 209Bi are calculated in the energy region from threshold up to 250 MeV. In particular, the inclusive cross sections of six emission particles and the production cross sections of all residual nuclei, as well as their energy spectra, are calculated and discussed.
