An experiment to evaluate a neutron flux for an irradiator using Cf was performed by the EC-JRC by applying the Westcott method to indium and gold activation foils. ISCN DG members subsequently developed an MCNP model for a flux comparison within the MEXT subsidiary budget for the promotion of applications related to nuclear security. The flux values are able to show values within 10% for the thermal evaluation with larger differences in the resonance peak energies. Contrarily, there are differences in the reaction rate and peak-count data-model comparisons that could provide new opportunities of basic science research.
