Résumé

The dosimetry of the experimental reactor CALIBAN was established for photon and neutron components and the kerma variations were evaluated according to the position (distance from the core, height, angle with the median room axis). Dosimetry was performed respectively with TLD (Al2O3) for the photon component and with passive silicon diodes, activation detectors (Au, In, Ni, Mg, Cu, S) and alanine pellets measured by ESR spectrometry for the neutron component. The neutron energy distribution was experimentally evaluated at different distances from the activities measured on the activated foil using the SNAC2 software and compared with those calculated with the Monte Carlo code MCNPX.
