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.”

In analyzing radiant energy exchange between fuel and coolant in a reactor, it is necessary to know the reflection, absorption, and emission characteristics of the fuel and its interface with the coolant. Because of the unavailability and great uncertainty of these radiation properties, they are calculated from the electromagnetic theory of optics, and results are presented here. Depending on the contacting medium, six types of surfaces received consideration. They are the interfaces between uranium dioxide and sodium, uranium dioxide and steel, uranium dioxide and a gas, water and a gas, steel and a gas, as well as sodium and a gas. The spectral interface reflectance and the spectral absorptance from one side of the medium to the other side are evaluated for all wavelengths. These spectral properties are further integrated to yield the total hemispherical properties for a black body source over a temperature range from 1200 to 6000 K. Comparisons are made with available experimental data or calculated values, and the agreement is found to be generally good.
