The neutron flux distribution in the TRIGA Mark II reactor core installed at the Applied Nuclear Energy Laboratory (L.E.N.A.) of the Pavia University was measured through the neutron activation technique, irradiating Al-Co samples in different positions among the fuel elements. The fast and integral fluxes were simultaneously measured in the same positions analyzing the 27Al(n,a)24Na threshold reaction and the (n,g) activation of 59Co, respectively. This measurement was used as experimental benchmark for validating the MCNP reactor model, which was recently upgraded to the present configuration through the burnup analysis of each fuel element.

Abstract
The neutron flux distribution in the TRIGA Mark II reactor core installed at the Applied Nuclear Energy Laboratory (L.E.N.A.) of the Pavia University was measured through the neutron activation technique, irradiating Al-Co samples in different positions among the fuel elements. The fast and integral fluxes were simultaneously measured in the same positions analyzing the 27Al(n,a)24Na threshold reaction and the (n,g) activation of 59Co, respectively. This measurement was used as experimental benchmark for validating the MCNP reactor model, which was recently upgraded to the present configuration through the burnup analysis of each fuel element.
