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
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.

TerraPower begins U.K. regulatory approval process
Seattle-based TerraPower signaled its interest this week in building its Natrium small modular reactor in the United Kingdom, the company announced.
TerraPower sent a letter to the U.K.’s Department for Energy Security and Net Zero, formally establishing its intention to enter the U.K. generic design assessment (GDA) process. This is TerraPower’s first step in deployment of its Natrium technology—a 345-MW sodium fast reactor coupled with a molten salt energy storage unit—on the international stage.
A voluntary consensus standards program, like the one at ANS, stands on the strength and diversity of its volunteers. ANS Standards only come into existence due to the hard work, loyalty, and dedication of its volunteer network of hundreds of qualified individuals in the industry. Because of this, ANS always looks for and welcomes new volunteers to its development process.
But more than just helping ANS, participation in a standards development process helps the industry. Active participation in our committees ensures that industry standards stay current and generates ideas for new standards that are needed in the field. Your participation in standards also means that no longer do you silently wish a standard would do something for your field, now you can actually work to make sure a standard accomplishes just that.
There's someone else who also benefits from participation in our standards program: you, the volunteer. The consensus process offers an excellent network of industry experts. You not only have the opportunity to meet and work with people from a variety of backgrounds, but you have a chance to learn from their experiences. The standards development process is all about shared knowledge. Check out the Standards Committee Member Survey Summary for an estimate on time commitment, benefits of participating, and other feedback from current Standards Committee members.
ANS Standards Committee members must subscribe to the Terms of Membership/Usage.
The best way to get involved is to find a current or proposed standard in which you have an interest and expertise. ANS working groups are the actual writing committees that create the text of a standard. Alternatively, you can get connected with a subcommittee that deals with your area of expertise, and investigate if there is a need for volunteers or even propose to create a standard that's of importance to your field.
In any case, your first step is the volunteer form. Procedures of the ANS Standards Committee require that a volunteer form be kept on file at ANS headquarters.
