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
Nuclear Nonproliferation Policy
The mission of the Nuclear Nonproliferation Policy Division (NNPD) is to promote the peaceful use of nuclear technology while simultaneously preventing the diversion and misuse of nuclear material and technology through appropriate safeguards and security, and promotion of nuclear nonproliferation policies. To achieve this mission, the objectives of the NNPD are to: Promote policy that discourages the proliferation of nuclear technology and material to inappropriate entities. Provide information to ANS members, the technical community at large, opinion leaders, and decision makers to improve their understanding of nuclear nonproliferation issues. Become a recognized technical resource on nuclear nonproliferation, safeguards, and security issues. Serve as the integration and coordination body for nuclear nonproliferation activities for the ANS. Work cooperatively with other ANS divisions to achieve these objective nonproliferation policies.

TVA to file for Clinch River SMR construction permit by June
In a Q&A posted on TVA’s website last week about a “new nuclear heyday,” Bob Deacy shared his vision for the Clinch River nuclear site in Oak Ridge, Tenn.—and some news about next steps for the company’s small modular reactor plans.
The Tennessee Valley Authority’s senior vice president for the Clinch River project, Deacy described his vision for up to four SMRs built on plots smaller than a football field with state-of-the-art digital equipment and a newly trained workforce providing reliable 24/7 power to the grid.
