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.

BREAKING NEWS: Trump issues executive orders to overhaul nuclear industry
The Trump administration issued four executive orders today aimed at boosting domestic nuclear deployment ahead of significant growth in projected energy demand in the coming decades.
During a live signing in the Oval Office, President Donald Trump called nuclear “a hot industry,” adding, “It’s a brilliant industry. [But] you’ve got to do it right. It’s become very safe and environmental.”

New nondestructive methods for determining burnup and fissile content are introduced. Indium-115 is activated to metastable state by hard gamma rays of a spent-fuel assembly, where the isomer activity produced is proportional to the fissile content. The application of a beryllium converter increases sensitivity by nearly two orders of magnitude and also reduces the time needed. Alternative or simultaneous detection of neutrons emitted by the spent fuel is also available: The produced 116mIn activity is a function of burnup. Principles are verified by many experiments on WWR-SM assemblies. Axial and azimuthal gamma-ray and neutron profiles are also recorded to demonstrate the ability of the methods to detect burnup inhomogeneities. The advantages of the methods and the choice of target material are discussed. Applications for safeguards purposes are suggested.
