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.
Mathematics & Computation
Division members promote the advancement of mathematical and computational methods for solving problems arising in all disciplines encompassed by the Society. They place particular emphasis on numerical techniques for efficient computer applications to aid in the dissemination, integration, and proper use of computer codes, including preparation of computational benchmark and development of standards for computing practices, and to encourage the development on new computer codes and broaden their use.

The consequences of closure: The local cost of shutting down a nuclear power plant
When on May 7, 2013, the Kewaunee nuclear power plant in rural Wisconsin was shut down, it took with it more than 600 full-time jobs and more than $70 million in lost wages, not including temporary employment from refueling and maintenance outages. Taking into account indirect business-to-business activity, the total economic impact of the closure of the single-unit pressurized water reactor was estimated to be more than $630 million to the surrounding three-county area.
COVID-19 Note: Please check this page often for meeting status updates due to the COVID-19 pandemic.
American Nuclear Society meetings and conferences are the best way to keep current with the ever changing fields of nuclear science and technology.
In addition to two national meetings per year, ANS sponsors many topical meetings which concentrate on a particular technical area. Many of these meetings are planned many years in advance and are listed here. To have a meeting listed here, it must be approved by the National Program Committee of the American Nuclear Society for inclusion on the ANS Calendar.
For more than 65 years, ANS has provided a forum for advancing the state of applied nuclear science and technology. We remain committed to serving the needs of the nuclear professional community during these unprecedented times. In the coming weeks, we will be introducing a new set of digital and video tools that will enable the robust technical exchange of an ANS meeting—papers, presentations, posters, and plenaries, etc.—while ensuring the health and safety of everyone involved during the COVID-19 pandemic.
