EXPERIMENTAL VALIDATION OF A MONTE CARLO BASED TOOLBOX FOR SELF-POWERED NEUTRON AND GAMMA DETECTOR SIMULATION IN THE OSIRIS MTR

摘要

The Instrumentation Sensors and Dosimetry Laboratory (LDCI) of CEA Cadarache (France) has been developing since 2010, a numerical toolbox based on Monte Carlo calculations for self-powered neutron and gamma detector design, simulation and operation, in order to save operators numerous and fastidious calibration tests. The paper details the experimental validation of this numerical toolbox in the OSIRIS Material Testing Reactor, with fully characterized experimental locations through dedicated Monte Carlo calculations of neutron and gamma flux levels and spectra, activation dosimetry and ionization chamber measurements. The presented C/E comparison results are very satisfactory and presuppose promising future application for the numerical toolbox called 'MATiSSe'. The LDCI MATiSSe toolbox is ready for nuclear instrumentation definition of irradiation experiments in the future Jules Horowitz Reactor (JHR) and applications even wider than research reactor community.
