Comparison of calculated and measured reaction rates obtained through foil activation in the subcritical dual spectrum facility YALINA-Booster

► Reaction rates were measured by the foil activation technique in the subcritical core of YALINA-Booster. ► The experimental results are compared with MCNP calculations using ENDFB-6.8, JEFF-3.1.1 and CENDL-3.1 libraries. ► A discrepancy of the C/E values for high-threshold reactions reaches up to 20% for all three libraries. ► An inaccurate cross section of 115In(n, γ)116Inm reaction is identified in CENDL-3.1. ► The results indicate a difficulty of precise reaction rate calculations by MCNP in subcritical systems using the common neutron cross section libraries.
