CABRI is an experimental pulse reactor operated by CEA at the Cadarache research center and funded by the French Nuclear Safety and Radioprotection Institute (IRSN).For the purpose of the CABRI International Program (CIP), operated and managed by IRSN under an OECD/NEA framework it has been refurbished since 2003 to be able to provide experiments in prototypical PWR conditions (155 bar, 300 DC) in order to study the fuel behavior under Reactivity Initiated Accident (RIA) conditions.This paper first reminds the design and the goals of the dosimetry program that was built in support of the commissioning tests performed for the reactor restart and requalification. Then it focuses on the irradiation conditions for each dosimeter and presents the measurement results. Finally, an analysis of the dosimetry campaign including measurement-calculation comparisons is presented.
