REMOTE CONTROLLABLE NEUTRON COINCIDENCE COUNTER FOR NON DESTRUCTIVE ACCOUNTING FOR NUCLEAR MATERIAL

摘要

The neutron measuring apparatus of the present invention, an outer case, a neutron detector installed in a state surrounded by a moderator in the outer case, can be exposed outside the outer case through the movement in the outer case, the cavity is installed to accommodate the sample container It is made of a basket, and an external signal analyzer connected through the detector and the conductive path, the conductive path connecting the detector and the external signal analyzer is provided with a simple connector of the one-touch connection method of the wire connected to the connector The removal exchange can be made freely.;In the present invention, a shielding body such as a lead plate for radiation shielding is usually installed in the outer case, and an amplifier may be provided in the detector itself or in the vicinity of the detector to transmit the sensed neutron signal to the data processing device. To access the basket, hatches may be installed to open a portion of the exterior to open the interior portion to facilitate internal operation during maintenance.
