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.

The energy and angular distributions of the protons from the 93Nb(n, xp) reactions were investigated by means of the Vienna multitelescope system. Whereas total hydrogen production cross sections are in fair agreement with previous results, considerable deviations from a previous measurement of the shape of the angle-integrated proton spectrum have been found. No other detailed measurements of the angular distributions have as yet been reported. The angle-integrated results are compared with calculations based on the statistical model of nuclear reactions, including precompound processes. It is shown that the proton emission spectrum can be described within this model if the usual pairing correction is also used for the exciton state densities within precompound calculations and otherwise a set of parameters which gives an adequate description of all other neutron-induced reactions of 93Nb. The angular distributions, which show a strongly energy-dependent forward-backward asymmetry, are compared to the results of a phenomenological model and to those of direct reaction theory for continuum cross sections.
