APRENDE Experimentalists-Evaluators workshop (WP2-WP4)

6 Jul 2026, 09:00 → 7 Jul 2026, 13:00 Europe/Zurich

PH B2 395 (EPFL)

Mathieu Hursin (EPFL), Maëlle Kerveno (CNRS)

The Addressing PRiorities of Evaluated Nuclear Data - APRENDE EURATOM project fosters the collaboration between experimentalists and evaluators. We are pleased to announce the second APRENDE meeting combining the communities of WP2 New Nuclear Data measurements  and WP4 Nuclear data evaluation. The workshop will be held, in person, at the EPFL in Lausanne, Switzerland, on July 6 and 7, 2026. Attendance to the meeting is by invitation only.

This meeting will be dedicated to the work (exp & eval) performed in APRENDE on Pu isotopes (deliverables 2.7, 2.8, 2.9, 2.12 , 4.5, 4.6, 4.9) aiming at the following objectives:

• Provide a description of experimental (XS, FY, resonance parameters & n prompt multiplicities measurements) and evaluation works on-going and foreseen in APRENDE, 
• Foster the discussions between all actors to better understand all the issues of experimental and evaluation activities,
• Share good practices to tend to efficient evaluations and the completion of deliverables.
