DEVICE FOR FILLING REACTOR SPACES WITH BULKHEAD BARRIER MATERIAL WHEN REACTORS DEPARTMENT FROM OPERATION

摘要

The utility model relates to the field of nuclear engineering. A device for filling the reactor spaces with bulk barrier material during decommissioning of the reactors contains a pneumatic chamber pump with an aeration element, made with a lower conical surface, on the gaskets of which there are nozzles for supplying aeration air, and perforated plates with a gasket between them, an aeration pipe with holes located inside the transport pipeline. The pneumatic chamber pump by means of quick disconnect connections is connected with a transport pipeline made in the form of a pipe through which the barrier material is fed into the reactor spaces. At the outlet from which, by means of threaded connections, a blowing nozzle is fixed, which is a sleeve divided by a T-shaped metal plate into two equal parts. On the outside of the transport pipeline using clamps secured pipe for compressed air. At the end of the pipe by means of threaded connections, a flow divider is installed in the form of a cross located under the blowing nozzle, at the outlet of which nozzles are located. The utility model allows you to create a safety barrier based on bulk clay-containing materials of the same density during decommissioning of the reactor. 1 ill.
