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.

Securing the advanced reactor fleet
Physical protection accounts for a significant portion of a nuclear power plant’s operational costs. As the U.S. moves toward smaller and safer advanced reactors, similar protection strategies could prove cost prohibitive. For tomorrow’s small modular reactors and microreactors, security costs must remain appropriate to the size of the reactor for economical operation.

As a part of ARIES-ACT research, we have been performing a detailed re-examination of requirements and design of vacuum vessels for fusion power plants. This paper discusses structural analysis performed in support of this examination. We have performed parametric 3-dimensional finite element analyses of ARIES-ACT-type vacuum vessels. The vacuum vessel structure is subjected to different types of loads such as atmospheric pressure, weight of the vessel itself and off-normal loads such as over-pressurization due to a leak in fusion core components, electromagnetic forces from disruptions, etc. Ribbed structure is considered in order to minimize the thickness of the vacuum vessel as well as to cool the system. We will discuss our results including structural response to various loads and trade-offs among structural design choices.
