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.
Nuclear Installations Safety
Devoted specifically to the safety of nuclear installations and the health and safety of the public, this division seeks a better understanding of the role of safety in the design, construction and operation of nuclear installation facilities. The division also promotes engineering and scientific technology advancement associated with the safety of such facilities.

Eisenhower’s “Atoms for Peace” at 70
Seventy years ago to the day, President Dwight D. Eisenhower gave his historic address to the United Nations General Assembly in New York City. (See December 2023 Nuclear News's “Leaders” column to read the reflections of Kathryn Huff, the Department of Energy’s assistant secretary for nuclear energy, on the speech’s anniversary.)

Although mainly distributed as a CFD toolbox, OpenFOAM is structured as a general open-source library for the discretization and parallel solution of partial differential equations on unstructured meshes. This combines with a high-level object-oriented API and with an intuitive finite-volume discretization method to allow for a streamlined development of advanced multi-physics solvers for various applications and by authors with various backgrounds. This is resulting in a rapidly growing community of users and developers, with a number of official and community-driven solvers that can nowadays help complement legacy nuclear codes with a wide geometric flexibility, HPC scalability, quick code tailoring, streamlined coupling possibilities, and a full transparency for improved E&T approaches.
The workshop will first present an overview of the multi-physics capabilities of OpenFOAM; listing its main features as a numerical library; highlighting some important achievements and milestones from various authors; singling out currently available solvers for nuclear applications; and discussing the lessons learned from a decade of development efforts. The objective will be to provide the audience with up-to-date information about the modelling possibilities provided by OpenFOAM and to summarize its strengths and challenges, thus allowing for more informed decisions about the opportunity to employ OpenFOAM, or existing OpenFOAM-based tools, for one's own applications.
The workshop will then provide a practical introduction to two open-source tools based on OpenFOAM, namely: the GeN-Foam code for the multiphysics analysis of nuclear reactors; and the OFFBEAT code for the 1.5-D, 2-D and 3-D simulation of fuel behaviour. Topics covered will include learning best practices, available resources, setting up a model, running, post-processing, basics of code tailoring. The objective will be to provide all necessary information for autonomous learning and use of these tools.
The workshop will be conducted as a mix of presentations, open discussions and practical examples. Participants are encouraged to test the practical examples on their own laptops. To that purpose, participants will need to have OpenFOAM 9 already installed (including paraFoam or paraview). Installation instructions are available at https://openfoam.org/download/
