Welcome to WANDA 2023,
We would like to ask that you save the date for the WANDA 2023 meeting February 27 – March 2, 2023. Invitations are in the works and well arrive shortly. This meeting will be held in-person ONLY.
WANDA is an annual meeting that addresses the value, needs, and impact of nuclear data on applied sciences. Please see below for this year’s session topics, session description and session co-chairs:
Fission Yields, where we were, are, and headed/Theory, Evaluation, Experiments, Validation
Chairs: Jason Harke (LLNL), Sebastian Schunert (INL)
Session Summary: Significant investment into improved measurements and theory combined with both national and international collaboration currently leading to the first US re-evaluation of fission product yields on the 30th anniversary of England & Rider’s release of ENDF-349. The enhancements in the fidelity and quality of fission product yield measurements and theory as a function of incident neutron energy was a dormant art before this investment. This session will review the historical needs that drove this investment to re-assess fission product yield data, their applications, and user data needs to identify what next steps in this focal area should be. Emphasis will be placed on the value of this data on reactor decay heat calculations, reactor fuel inventory estimates, and national security needs. This session will focus on:
Isotope Programs Session
Chairs: Etienne Vermeulen (LANL), Andrew Voyles (UC Berkeley)
Session Summary: The isotope production landscape has changed significantly over the last four years, both because of the war in Ukraine as well as additions from new commercial suppliers in the medium energy proton range and with electron accelerators. This session aims to check in with the 2018 speakers for a status update and an assessment of the changes in needs across the isotope production field. This session will focus on:
Gamma-Ray Strength Functions and Level Densities
Chairs: Stephanie Lyons (PNNL), Gencho Rusev (LANL)
Session Summary: The session will contain focused discussions on specific research applications of gamma-ray strength functions and levels densities, for example, Hauser-Feshbach calculations (Monte Carlo or deterministic) and neutron-capture cross sections calculations, astrophysical network calculations, radiation transport simulations, calculations of the gamma-ray heat in reactors, and the reactor antineutrino problem. This session will focus on:
(The Future of) Nuclear Data Processing & Preservation
Chairs: Libby Ricard-McCutchan (BNL), Nathan Gibson (LANL)
Session Summary: This bi-modal session will start with a discussion about expanding data availability and the rapidly evolving computational landscape. New computing architectures and simulation approaches require changes in nuclear processing and formatting to support new methods. Discussions about data preservation will follow in the afternoon. Sophisticated datasets are seldom mined for all their richness and often analyzed with a focused goal and then shelved. This is inefficient, both intellectually and financially. A newly issued OSTP memorandum will require data underlying federally funded research to be made “freely available and publicly accessible by default at the time of publication.” This session will focus on:
