Abstract :
Experimental programs led in zero power reactors are mainly devoted to neutron lattice and core code validation. As a consequence, and in order to be relevant of neutron behavior in power reactors, the experiments must be representative for the neutron properties. Zero power reactors have the advantage of enabling the measurement of quantities that are inaccessible in power reactors. The study is made on a limited experimental database to analyze the transposition of C/E (calculation-to-experiment) results and associated uncertainties from different experimental programs (Pre-Racine, ZPPR or criticality experiment) to the CFV SFR Gen-IV concept currently being developed by CEA. Finally we present a rigorous method to combine technological and measurements uncertainties linked to the experimental techniques to generate covariance matrices between integral quantities.
