Workshop for Applied Nuclear Data Activities (WANDA) 2025
Hilton Arlington National Landing, 2399 Richmond Hwy, Arlington, VA, 22202
Sessions:
Nuclear Data and Deterrence
Chairs: Jo Ressler (LLNL), Todd Bredeweg (LANL), Aaron Couture (LANL)
The US maintains a nuclear arsenal as part of its broader deterrence strategy. In 1992 the US stopped full scale testing of nuclear weapons, establishing the Stockpile Stewardship Program (SSP) in 1995. The SSP is science-based, using predictive capabilities developed with modeling, simulation, and laboratory experiments to certify the current nuclear stockpile and prepare for the future deterrent. These activities require accurate physical data (including the nuclear data library), knowledge of uncertainties to define confidence and prioritize efforts, and integrated experiments to validate computational assessments. In this WANDA session, nuclear data needs and next-generation capabilities will be discussed.
Nuclear Data Prioritization for Fusion
Chairs: Michael Loughlin (ORNL), Lee Bernstein (LBNL), Wim Haeck (LANL)
With a wide array of possible designs and methods for deploying fusion energy applications, there are many coinciding nuclear data needs. Some of these nuclear data are more important than others for fusion applications, and some nuclear data has not yet been fully characterized or validated. This session is designed to discuss and find consensus on nuclear data priorities for fusion, based on the intended application space and uncertainty in the data.
Challenges in the Deployment of HALEU and Novel Moderators for Advanced Reactors
Chairs: Theresa Cutler (LANL), Javier Ortensi (INL)
Advanced Reactors have recently become an important topic in the nuclear community. There is broad interest in all facets from design, material fabrication, processing, transport, and disposal. DOE has offered multiple grants to companies in recent years to design advanced reactors and establish prototypes. The HALEU Availability Program is working to establish pathways to acquire HALEU commercial scales to support these advanced reactor concepts. To support the renewed effort in building advanced reactors, nuclear data needs a close eye and potentially significant improvements/uncertainty reduction. With the roll out of the DNCSH which specifically looks at criticality safety for transport and processing, the full suite of nuclear data and its impacts to the goals and methods needs to be considered. In addition, the deployment of novel moderators such as metal hydrides in combination with HALEU fuel forms pose new challenges in both design and transportation due to the lack of relevant benchmarks.
Data Preservation & Data Workflows
Chairs: Adam Daskalakis (NNL) and Dave Brown (BNL)
This session approaches data preservation and data workflow from the position of trying to identify common practices and pitfalls within our community as it pertains to the generation of well documented, retrievable, and formatted nuclear data. We divide this session into four generalized topics, each intended to facilitate the greatest amount of discussion and positive momentum. The session starts with Open Data, how the community accesses, stores, and transmits information; contrasted with recent guidance. This ties in with the current state of Legacy Data and how the community leverages the current landscape, with its known obstacles, to deliver nuclear products. Data Workflow takes a more systemic view of the nuclear data pipeline and information sharing between different segments. Tying it all together Data Preservation and Workflow Preservation Knowledge Management looks to past practices and future knowledge management methods as the key to best leverage past work for future endeavors.
