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.

Four million nuclear jobs by 2050: Who will do them?
Industry leaders from around the globe met this month to discuss the talent development that will be necessary for the long-term success of the nuclear industry.
The International Conference on Nuclear Knowledge Management and Human Resources Development, hosted by the International Atomic Energy Agency, was held in Vienna earlier this month. Discussed there was the agency’s forecast for nuclear capacity to more than double—or hopefully triple—by 2050 and the requirement of more than four million professionals to support the industry.

The objective of this effort is to minimize the excess reactivity of the liquid-metal reactor (LMR) over the core cycle, which will allow control rods to have less worth to control the core. This reduces the potential available transient reactivities and thus improves the LMR’s inherent safety characteristics. The core characteristics are modified to effect a constant keff over the cycle. Use of limited moderator and poison islands is incorporated into the core design to optimize the LMR core geometry and to help achieve the design objective. The feasibility of this concept is shown to be valid by an example, and further possible improvements in the method are suggested.
