摘要： The invention relates to a device for the in-line measurement of a flow of rapid epithermal neutrons, characterised in that the device includes: a rapid epithermal neutron detector (DNR) capable of mainly detecting rapid epithermal neutrons; a thermal neutron detector (DNT) capable of mainly detecting thermal neutrons; a first processing circuit (C1) for processing the signal supplied by the rapid neutron detector; a second processing circuit (C2) for processing the signal output by the thermal neutron detector; a means (CE, PPM) capable of determining the evolutive sensitivity to rapid neutrons and thermal neutrons of each of the neutron detectors; and a computer (CALC) for calculating the rapid and epithermal neutron flow from said evolutive sensitivities and from the signal supplied by the first and second processing circuits.
