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.

G7 pledges support for nuclear at Italy meeting
The Group of Seven (G7) recommitted its support for nuclear energy in the countries that opt to use it at a Ministerial Meeting on Climate in Italy last month.
In a statement following the April meeting, the group committed to support multilateral efforts to strengthen the resilience of nuclear supply chains, referencing the goal set by 25 countries during last year’s COP28 climate conference in Dubai to triple global nuclear generating capacity by 2050.

Microreactors present promising opportunities to open new nuclear energy markets. However, it is expected that the economic competitiveness of this new class of reactors will hinge on potential cost reductions via mass production. It is therefore critical to begin assessing important considerations for the factory production of microreactors. An overview of the important aspects of the general layout of a microreactor factory, along with best practices to be incorporated early in the design process, is provided in this study. Then, a detailed use case is considered and modeled using a dedicated tool that can map workflows and activities within a factory. The end product is a 242 000 sq. ft. factory model that can ramp up production from 10 to 100 units per year.
Based on the activities and workflows needed, cost estimates for equipment and staffing needs are generated. These are expected to be first-order estimates, but would still provide guidance on the level of investment needed to reach mass production levels of microreactors. Furthermore, the potential cost reductions from scaling production are quantified. It was found that for a 100-unit factory throughput, reductions above 70% per unit cost relative to a prototype demonstration, could be observed for tasks conducted within a factory. These estimates focus solely on component fabricated at a factory and do not account for fuel costs nor any site activities. Because the analysis is design specific, not all findings are expected to be applicable across different microreactors (notably larger varieties), but it still provides a foundation establishing the basis for the mass production of these reactors.
