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.

A review of workforce trends in the nuclear community
The nuclear community is undergoing a moment of unprecedented interest and growth not seen in decades. The passage of the bipartisan Infrastructure Investment and Jobs Act and the Inflation Reduction Act are providing a multitude of new funding opportunities for the nuclear community, and not just the current fleet. A mix of technologies and reactor types are being evaluated and deployed, with Vogtle Units 3 and 4 coming on line later this year, the Advanced Reactor Demonstration Projects of X-energy and TerraPower, and NuScale’s work with Utah Associated Municipal Power Systems to build a first-of-a-kind small modular reactor, making this is an exciting time to join the nuclear workforce.

A prototype negative ion source is in development toward the giant negative ion source for the China Fusion Engineering Test Reactor neutral beam injection system at the Institute of Plasma Physics, Chinese Academy of Sciences. The multiaperture and multichannel grids are the most challengeable during the construction of the prototype negative ion source. The research and development activities for the grid manufacturing method were carried out and divided into detailed design, implementation, and testing phases. Based on a special manufacturing process involving the vacuum brazing technique, some prototype grids were produced. Two prototypes have similar structures to the extraction grid of the prototype negative ion source except for the reduced number of cooling channels. A testing campaign (including dimension inspection, leak tests, thermal imaging tests, and magnetic tests) was carried out. The results demonstrate that the manufacturing process and construction technology can meet the requirements of the extraction grid and can promote the construction of other grids or components having a similar structure.
