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.

New laws offer nuclear industry incentives for existing power plant uprates
This year, the U.S. nuclear industry received a much-needed economic boost that could help preserve operating nuclear power plants and incentivize upgrades that extend their lifespan and power output.
Signed into law in 2022, the Inflation Reduction Act offers production tax credits (PTCs) for existing nuclear power plants and either PTCs or investment tax credits (ITCs) for new carbon-free generation. These credits could make power uprates—increasing the maximum power level at which a commercial plant may operate—a much more appealing option for utilities.

A model is presented describing the phenomenon of liquid entrainment resulting from the presence of Kelvin-Helmholtz instability at the gas-liquid interface of a sonic gas jet submerged in a mass of liquid. On the basis of this model, available experimental data regarding the rate of entrainment were correlated satisfactorily. The correlation thus obtained is of importance in deriving the heat transfer coefficient in the impingement area of a fuel pin impinged upon by a fission-gas jet released from a failed pin in a liquid-metal-cooled fast breeder reactor fuel subassembly.
