Daniel Lopez Aldama
5/13/25, 10:00 AM

The Fusion Evaluated Nuclear Data Library (FENDL), coordinated by the IAEA’s Nuclear Data Section, is a key resource for nuclear data in fusion energy applications. The project involves a broad international collaboration to evaluate, process, validate, and document nuclear data relevant for both Monte Carlo and deterministic simulations.
Recent developments have led to the preparation of...

Saerom Kwon
5/13/25, 10:30 AM

We reviewed some issues presented at the 2023 FENDL meeting and summarized the requests for the next FENDL release about Iron, Copper, Beryllium data. Also we examined an issue which F4E group encountered in analyzing FNG tungsten experiment, which suggests that a lot of files in FENDL-3.2c include data which NJOY does not support.
19. Recent Advances in Deuteron Nuclear Data Evaluation for Structural Materials: Iron Isotopes
Shinsuke Nakayama
5/13/25, 11:00 AM

Since iron is one of the primary structural materials used in accelerators, to evaluate radioactivity production and design radiation shielding for the International Fusion Materials Irradiation Facility (IFMIF) and its precursor facilities, accurate nuclear data on deuteron-induced reactions for iron are essential.
　These data include production cross sections of key radioactive isotopes...

Ruirui Xu
5/13/25, 1:30 PM

Fusion energy serves as an alternative to fossil fuels, providing zero-carbon operation and virtually inexhaustible fuel supplies. CENDL has not yet established a special evaluated data library for fusion, while already includes some nuclei required by the fusion equipment. The talk includes the brief explanation of research work related to the CENDL project, Chinese nuclear reaction data...

7. Improving nuclear cross-sections with deep learning: DINo algorithm
Lévana Gesson
5/13/25, 2:30 PM

The DINo (Deep learning Intelligence for Nuclear reactiOns) algorithm is a deep neural network designed to improve predictions of nuclear reaction cross-sections, crucial for applications like particle therapy in cancer treatment. Trained on TENDL 2021 data, DINo significantly outperforms traditional models, especially for proton–carbon interactions, achieving better agreement with...
37. Benchmark experiment for large angle scattering cross section of 14 MeV neutrons.
Yamato Fujii
5/14/25, 9:30 AM

The scattering cross section at large angles varies depending on the nuclear data library. To validate these cross sections, we developed a benchmark experimental system and conducted measurements for several elements, including iron and tungsten. For iron, calculations based on the ENDF/B-VIII.0 showed good agreement with the experimental results. In contrast, for tungsten, JENDL-5 and...

The contribution provides a comprehensive overview of the FENDL3.2c nuclear data library, its verification and validation (V&V) process, and its impact on ITER analysis.

FENDL3.2c is the most up-to-date nuclear data library recommended by the IAEA for ITER applications. It includes transport data and activation data from TENDL-2017. The V&V process for FENDL3.2c is extensive, involving...

In the last couple of years, JADE development has been pushed forward by Fusion For Energy and UKAEA with a new objective: use the JADE framework also to perform code to code comparisons. This new collaboration led to JADE v3, a first proof of concept that ported the tool on the linux platform and allowed for the first time to run benchmarks not only with MCNP but also with OpenMC. During this...
