Criticality monitoring device and fissile materials concentration measurement
Description
The device is based on neutron activation inducing nuclear reactions which are analyzed for quantitative analysis. It includes a first unit comprising a neutron source inside a block of hydrogenated materials and a first neutrons detector, a second unit comprising a block of hydrogenated materials contained inside materials stopping thermal neutrons and a second neutron detector inside the hydrogenated materials. The two blocks are placed on both sides of the monitored area

Le dispositif est base sur l'interrogation neutronique active. Il comporte un premier ensemble constitue d'une source de rayonnement neutronique, d'un bloc de materiau hydrogene et d'un premier detecteur de neutrons, un second ensemble constitue d'un bloc de materiau hydrogene entoure d'un materiau arretant les neutrons thermiques et d'un second detecteur de neutrons place dans le bloc de materiau hydrogene. Ces deux ensembles sont places de part et d'autre de la zone a controlerAdditional details
