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.

Countering the nuclear workforce shortage narrative
James Chamberlain, director of the Nuclear, Utilities, and Energy Sector at Rullion, has declared that the nuclear industry will not have workforce challenges going forward. “It’s time to challenge the scarcity narrative,” he wrote in a recent online article. “Nuclear isn't short of talent; it’s short of imagination in how it attracts, trains, and supports the workforce of the future.”

The time-dependent linear Fokker-Planck equation governing the transport of fast ions in a spherical host medium is solved in the suprathermal energy range, including both continuous slowing down and angular diffusion. Because of the parabolic nature of the angular dispersion term, an implicit time-centered scheme is proposed. On the other hand, a second-order diamond approximation in energy and space is chosen to avoid the spurious numerical diffusion driven by the usual first-order methods. The last variable, the pitch angle cosine, is discretized by centered finite differences. Good accuracy is demonstrated when comparing the results of the proposed method with the “exact” values given in the literature for some benchmark problems or by checking energy and particle balance equations. A numerical code (CIRCE) based on this scheme has been developed; it can be coupled to standard one-dimensional hydrodynamics codes after a few straightforward modifications.
