"Multifaceted Coded Nuclear Data Libraries Assemblage: TENDL-2025"

• J.-Ch. Sublet
• Arjan Koning
• Dimitri Rochman

The multipurpose, multifaceted methodical nuclear data libraries coded by TALYS [1] & databases [2], TEFAL, TASMAN [3] as the Evaluated Nuclear Data Library TENDL has now been released every other year recently. Considerable experience has been acquired during the production years of global …

"A comparison of oxide decay heat simulations and nuclear data libraries with fusion irradiation experiments"

• M Pillon
• J-C Sublet

Cooling water in the primary circuit in both fission and fusion nuclear reactors is unavoidably exposed to neutrons leading to the generation of problematic short-lived isotopes, most importantly, 16N (T1/2=7.3s) via the 16O(n,p)16N reaction. This presents a significant itinerant radiation source to consi…

"Nuclear data V&V analysis for fusion applications: integral benchmarks and decay data"

• Olga Vilkhivskaya
• Mark Gilbert

Recent studies of the neutron irradiation conditions predicted in the plasma-exposed first wall of a conceptual design of fusion DEMO power plant implementing the SPECTRA-PKA code have shown the importance of taking into consideration per-channel analysis of the high-energy threshold reactions for an accurate evaluation of their contribution to …

"Interrogation and analysis of complex fusion decay heat benchmark simulations"

• Mark Gilbert
• J.-Ch. Sublet

Validation and verification (V&V) benchmark exercises form an important part of the development and release of the FISPACT-II inventory code and its associated input nuclear data libraries. This paper describes the latest V&V based on the fusion decay heat measurements performed at the Japanese FNS facility. New and novel assessment techni…

"NEUTRON-INDUCED DAMAGE SIMULATIONS: NOVEL NUCLEAR DATA FORMS AND METRICS FOR MATERIAL SCIENCES"

• Jean-Christophe Sublet
• Mark R. Gilbert

Nuclear interactions can be the source of atomic displacement, embrittlement and post-short-term cascade annealing defects in irradiated structural materials. Such metrics are derived from, or can be correlated to, nuclear kinematic simulations of primary atomic energy distributions spectra and the quantification of the numbers of secondary defects…
