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.”

The QPANDA nodal models, which are embodied in the SIMULA TE-3 code, have been extensively tested and benchmarked. Comparisons to quarter-core PDQ depletion calculations demonstrate the high degree of accuracy with which power distributions are predicted, even though SIMULA TE-3 contains no user-adjusted normalizations. The QPANDA pin power reconstruction model is introduced, and comparisons (versus CASMO colorset and PDQ quarter-core calculations) demonstrate that accurate pin power distributions are obtained by modulating the intranodal power distributions with single-assembly CASMO pin power distributions. Comparisons of SIMULATE-3 calculations to measured reactor fission rate integrals are presented. Also, the overall accuracy of the CASMO-3 cross sections, the QPANDA nodal model, and the QPANDA pin power reconstruction model is demonstrated.
