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.

A total of 22 gamma-ray transitions were measured from (n,n′γ) reactions on the four even-even nickel isotopes, 58,60,62,64Ni. Absolute gamma-ray production excitation functions at 125 deg were extracted for these transitions from their thresholds up to neutron energies of 4 MeV. Inelastic neutron scattering cross sections for 19 levels were inferred from the gamma-ray production data and compared to the Evaluated Nuclear Data File (ENDF/B-IV, MAT 1190). Cross-section agreement for the first excited 2+ states in these four isotopes is generally good, but excitation functions associated with many of the higher excited states in nickel are in strong disagreement with the file.
