DEVICE FOR MEASURING PHYSICAL QUANTITIES OF NUCLEAR MATERIALS AND METHOD OF EMPLOYING SUCH A DEVICE

摘要

Movable device for measuring physical quantities of nuclear materials contained in a shielded cell (2), which device can be brought up against said shielded cell (2) and can be retracted therefrom, said device being intended to carry out the measurement in the position in which it is against the shielded cell (2), the device comprising a carriage (8), a support member placed on the carriage (8) and a shielded container (4) placed on the support member. The shielded container (4) contains a transfer container (24) intended to store the nuclear material to be measured, the shielded container (4) having an opening intended to be aligned with an opening (14) in one wall of the shielded cell (2). The support member (44) is made of graphite and includes a housing (48) accommodating a neutron emission module (50), a casing (53) covering the shielded container (4), said casing (53) being made of graphite, and neutron measurement means (59) fastened to the casing.
