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.

World Nuclear Energy Day grows in recognition
Since its inception in 2020, World Nuclear Energy Day has grown in awareness each year. The day is celebrated annually on December 2.
This year on December 2, the U.S. Senate passed a resolution for World Nuclear Energy Day, celebrating the peaceful development of nuclear energy technology and underscoring the vital role of nuclear power in strengthening the U.S. economy and supporting a reliable energy grid worldwide.
The Consortium for Advanced Simulation of Light Water Reactors Virtual Meeting

Several of the challenge problems in CASL required accurate nuclear fuel performance modeling capabilities for their solution, especially Pellet-Clad-Interaction (PCI) and Loss-of-Coolant-Accident (LOCA)/Reactivity-Insertions Accident (RIA). In order to address these challenge problems, CASL contributed to the development of the Bison fuel performance code and made significant investments in both capabilities and validation needed for the two challenge problems referenced above. In addition, CASL played a key role in developing Bison capabilities for Accident Tolerant Fuels (ATFs). Fuel performance modeling is closely tied to the underlying materials models. In several cases, CASL sought better models using multi-scale materials modeling and simulation techniques, which are particularly important for ATF concepts where experimental data is scarce. This panel session will discuss materials and nuclear fuel performance modeling performed in CASL. It will highlight historical perspectives, accomplishments, lessons-learned and remaining challenges.
