The use of the Area method to analyze Pulsed Neutron Source (PNS) experiments as a means of measuring the reactivity during the reactor loading in order to prevent loading error was studied in the phase 1 of the SALMON project. This paper presents the experiments carried out at the GUINEVERE facility, using the GENEPI-3C accelerator to generate neutron pulses in the VENUS-F fast neutron reactor at different steps of its unloading. The evolution of the neutron flux during these PNS experiments was measured by several 235 U Fission chambers in various positions in the inner and outer reflector. The results show that, despite strong spatial effects observed in the least reactive configurations, a strong correlation between the reactivity value given by the Area Method and the true reactivity remains. Furthermore the responses to all detectors to PNS experiments could be reproduced and corrected using Monte Carlo simulations.
