FIELD: physics.
SUBSTANCE: device for controlling enrichment of U235, as well as content of Gd2O3 in the nuclear fuel moulding powder, containing a hopper connected by a filling tube to the tablet pressing device, a detector of its own gamma radiation located in close proximity to the side wall of the filling tube. The device is equipped with an industrial computer containing a spectrometer, which allows obtaining and analyzing the spectral characteristic of the registered gamma radiation of the uranium moulding powder containing gadolinium oxide.
EFFECT: operational control of uranium enrichment 235, as well as the content of gadolinium oxide, taking into account the density of the measured sample.
