4WDB.00001: Modern Covariances and Uncertainty Quantification in Nuclear Data and Applications Invited Speaker: Kyle A Wendt Evaluated nuclear data lies at the heart of the interface between nuclear physics and the broader world of scientific and societal applications of that nuclear physics, from modeling the life cycle of stars and cataclysmic astrophysical events to the production of power and radiological medical therapies and diagnostics. Quantifying the uncertainties of that nuclear data, and propagating that uncertainty forward, is crucial to enable these applications to determine the level of confidence level of their predictions, which has a significant impact on the reliability of the extracted science and the safety of the society applications. This presentation will cover recent efforts that span the whole gamut of producing nuclear data covariances for new evaluations, propagation of those uncertainties into applications, and novel techniques under development to fill in the gaps in our current nuclear data libraries when new evaluations are unavailable. |

4WDB.00002: Muon nuclear data Invited Speaker: Megumi Niikura The nuclear muon capture reaction is the capture of a negative muon by a proton in a nuclear medium via weak interaction from the 1s state of the muonic atom. When the muon stops in the matter, the muonic atom is formed and deexcited to the 1s state. The reaction probability of the muon capture is more than 90% for the muonic atom with heavy elements. The excitation energy populated by the reaction is distributed around 10–50 MeV, producing several radioactive nuclei followed by particle emissions. |

4WDB.00003: Update On The Nuclear Data Working Group: Cross Cutting Activities in Nuclear Data Invited Speaker: Todd A Bredeweg The Nuclear Data Working Group (NDWG) was founded in 2015, the membership of which consisted of national laboratory representatives nominated by each of the participating federal program managers. Today, the NDWG consists of 40 members representing 17 federal programs and 11 national laboratories with an additional 5 members at large. The primary responsibilities of the NDWG are to facilitate collaboration across federal programs and recommend topics for experimental research and data compilation relevant to mission-oriented applications. The main tool used to accomplish these goals is the annual Workshop on Applied Nuclear Data Activities (WANDA). These workshops are designed to facilitate discussion among the attendees with the goal of identifying and prioritizing opportunities to enhance the fidelity and impact of a variety of nuclear data activities. The WANDA workshops are open to all interested parties and are intended gain consensus on prioritized, cross-cutting nuclear data needs. The reports generated from each workshop guide federal programs that fund nuclear experiment, theory, and evaluation in support of their respective modeling and simulation efforts. The NDWG has also organized several, more focused workshops on specific topics of broad interest to the nuclear data community. |
