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.

From remediation to production: The DOE’s Cleanup to Clean Energy initiative
On July 28, 2023, the Department of Energy launched its Cleanup to Clean Energy initiative, an effort to repurpose underutilized DOE-owned property—portions of which were previously used in the nation’s nuclear weapons program—into the sites of clean-energy generation.

The EPICURE experimental program provides a complete and high-quality experimental database for evaluating the uncertainties in reactor physics calculations of plutonium-recycling pressurized water reactors. To understand possible discrepancies between experimental values and values calculated with the conventional scheme, a study is performed of the major physics approximations involved in the calculation of heterogeneous Mixed OXide-UO2-fueled cores. This study determines the origin of the significant discrepancies between the calculated and the measured power distributions. An optimized calculation scheme is developed based on the use of Sn transport calculations and on a refined energy group structure. Its application to the analysis of EPICURE experiments results in very satisfactory agreement.
