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.

Japanese researchers test detection devices at West Valley
Two research scientists from Japan’s Kyoto University and Kochi University of Technology visited the West Valley Demonstration Project in western New York state earlier this fall to test their novel radiation detectors, the Department of Energy’s Office of Environmental Management announced on November 19.

The U.S. Dept. of Energy (DOE) Office of Science and the National Nuclear Security Administration initiated the Exascale Computing Project (ECP) in 2016 to prepare mission-relevant applications and scientific software for the delivery of exascale computers to DOE in 2023. The ECP currently supports 24 science applications, 6 supporting co-design projects, and greater than 80 scientific software libraries in pursuit of this mission. In this talk I will introduce the ECP and give an overview of the application development focus area. The challenges associated with converting multiphysics scientific applications to heterogeneous computer architectures, and the approaches taken in the ECP, will be shown. I will discuss the programming models used in the ECP to achieve performance portability across a range of computer architectures. Finally, I will show highlights and discuss specific challenges in the ECP energy applications portfolio that consists of six projects modeling wind power, combustion, nuclear reactors, chemical looping reactors, fusion tokamak reactors, and plasma accelerators.
Radiation effects play an important role in nearly every aspect of our understanding of core-collapse supernovae, from neutrino transport in the dense central engine to the photon transport behind the luminous emission from the supernova blast wave. Modeling the radiation accurately is important in using observations of these cosmic explosions to understanding both the physical mechanism behind supernovae but also the fundamental physics behind supernova explosions. In this talk, I will review the different transport processes and some of the more challenging aspects of the transport modeling in these different regimes. I will focus on a new challenge posed by future NASA missions to model observations of supernova shock breakout.
