Description
After more than 10 years of use of the present code version, the AARE [1] framework for
conducting activation analyses of accelerator driven systems is being reworked to continue
to support analysis workflows in concert with the MCNP [2] multi-particle transport code.
The presentation focuses on the data library eMort.
To meet the expansion of the MCNP6 code, which includes transport cross section libraries
for neutrons and light ions to 150+ MeV energies, an upgrade of the activation cross section
libraries is needed. The new AARE libraries will provide activation cross section libraries to
150 MeV energy for neutrons, the light ions protons, deuterons, tritions, helions and alphas,
and including gammas building mostly on the data bases provided from TENDL2023 [3].
Missing fission fragment yield information in these data bases were provided by analyses
with a modified version of the TALYS-2.0 code [4], which makes use of the 2023 version of
the GEF [5] fission model.
The decay database was based mostly on ENDF/B-VIII.0 [6], however needed significant
extension to meet the wealth of nuclides coming out of the high-energy interactions. The
gaps were filled by tapping into the recent Nuclear Data Sheets, the Evaluated Nuclear
Data Files [7], and Moeller’s 2019 article [8].
