American Nuclear Society

Home / Constituencies / Professional Divisions

ANS is a diverse society that represents a vast array of nuclear science and technology disciplines. Made up of 19 professional divisions, one technical group, and two working groups, the Professional Divisions provide members a means to participate in society and support the development of the nuclear industry. ANS members may choose to belong up to two divisions or a division and technical group.

The Professional Divisions Committee (PDC) governs and coordinates the activities of the Professional Divisions and Technical Group. Division downloads are available on the PDC page.

For more information on the Professional Divisions and what they have to offer ANS members, please read this article by Dr. Hans Gougar and Dr. Rachel Slaybough.

Nuclear Nonproliferation Policy
Web Site:

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.
