Abstract

A description is given of a method and a device for determining the subcriticality of uranium masses by directing (11) epithermal neutrons onto the mass, isolating (13) the material from external thermal neutrons and measuring (30, 32, 33, 34) the ratio of thermal and epithermal neutrons to epithermal neutrons, which permits calculation (35) of a subcriticality value representative of the uranium mass.
