Improvements in neutron and gamma measurements for material testing reactors

Abstract

International audienceIn order to ensure the quality and the relevance of irradiation programs in the future Jules Horowitz Reactor (JHR), the French Alternative Energies and Atomic Energy Commission (CEA) has significantly increased its RandD effort in the field of in-pile instrumentation during the last decade. Major progresses have thus been achieved in the capability to perform accurate in-pile measurements using reliable and updated techniques. Benefits of this enhanced measurement potential, illustrated with some improvements achieved in neutron and gamma flux detection, are described in this paper.This paper also discusses the needs for irradiation capabilities within the coming years, in order to complete the in-pile qualification of newly developed sensors and the extensive validation of their corresponding simulation model
