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.

How can the U.S. ensure new nuclear builds get off to a good start?
Bradley Williams
The United States is already off to a good start with respect to new nuclear deployment. The completion of Vogtle Units 3 and 4, the Natrium groundbreaking, and X-energy’s partnership with Dow Chemical to deploy an advanced reactor for industrial applications are all important first steps. These efforts are being complemented by the flurry of licensing activity with the Nuclear Regulatory Commission and overwhelming support in Congress and the White House. But to achieve the current administration’s goal of tripling nuclear capacity by 2050, more needs to be done.

The material bucklings of twenty-five D2O moderated lattices of natural UO2 rod clusters were measured in the Process Development Pile (PDP). The measurements were made in one-region loadings, and should therefore be subject to little systematic error. A number of the lattices employed voided housing tubes around the fuel assemblies. Values of migration areas inferred from measurements of positive periods are also presented. An evaluation of the errors in the buckling measurements indicated that the bucklings should be accurate to about 1%. The migration areas are compared with theoretical values obtained from the Benoist theory, and the agreement is shown to be good.
