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.

Stress histories in bonded duplex structures subject to creep and surface erosion are explored using the finite element method. Erosion is simulated by reducing the elastic modulus of the appropriate elements by several orders of magnitude. In the absence of creep, erosion of a graphite tile on a copper substrate is found to have no effect on the interface stresses in the structure. Stress relaxation in the copper substrate reduces the differences in the stiffnesses of the two materials, leading to enhanced erosion effects in the presence of creep. Erosion thus is found to increase the stress relaxation rate.
