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.

Report: New York state adding 1 GW of nuclear to fleet
New York Gov. Kathy Hochul has instructed the state’s public electric utility to add at least 1 gigawatt of new nuclear by building a large-scale nuclear plant or a collection of smaller modular reactors, according to the Wall Street Journal.

A MOOSE (Multiphysics Object-Oriented Simulation Environment) based application, TREX, has been developed for modeling and simulation of advanced ceramic waste forms at multiple length scales. A method was developed for incorporating microstructural details at the mesoscale and computing effective material properties that can then be applied at the engineering scale capable of modeling the entire waste form. The work described includes the creation of Kernel, Material, and Postprocessor objects necessary to model the advanced ceramic waste form. Using these developed tools, the diffusion of cesium was modeled in a hollandite waste form. Experimental data and first principle calculations taken from the literature were used to inform models of the hollandite material properties.
