DESCRIPTION:Nuclear Data Needs for Antineutrino Spectra and their Applicat
 ions\n\nA workshop on the status of reactor antineutrino flux and spectrum
  measurements—and their comparison with model predictions—will be held
  at IFIC (CSIC-University of Valencia) from 4 to 8 May 2026.\n\nWhile s
 ignificant experimental and theoretical progress has been achieved over th
 e past two decades\, the foundations of reactor antineutrino flux models s
 till rely on the integrated beta-spectrum measurements performed by Schrec
 kenbach et al. at ILL in the late 1980s. More recent measurements of the 2
 35U/239Pu beta-spectrum ratio by Kopeikin et al. at the Kurchatov Institut
 e have revealed discrepancies of approximately 5%\, suggesting potential n
 ormalization issues in the original ILL data.\n\nFurthermore\, the first h
 igh-precision measurements from JUNO offer exceptional potential to improv
 e our understanding of long-standing questions—such as the Reactor Antin
 eutrino Anomaly (RAA) and observed spectral distortions—while providing 
 deeper insight into the underlying nuclear physics effects.\n\nThe worksho
 p will focus on the following primary topics:\n\n- Discussion of the possi
 bility of a new measurement of aggregate beta-energy spectra for the main 
 actinides\, enabling a direct comparison with the ILL reference measuremen
 ts\n\n- Latest results from the recent JUNO measurements\n\n- Advances in 
 decay data from recent TAGS and beta-spectrum experiments\n\n- Impact of t
 he JEFF-4.0 fission-yield evaluation\, including associated uncertainties 
 and covariances\n\nThe scientific programme will include presentations fol
 lowed by roundtable discussions allowing ample time for scientific exchang
 e.\n\nThe workshop is organized in collaboration with the International A
 tomic Energy Agency (IAEA) and it is supported by the following instituti
 ons and grants including CEX2023-001292-S.\n\n\n\nhttps://indico.ific.uv.
