PROCESS CHANNEL COMBINED FOR INDUSTRIAL NUCLEAR PLANT

摘要

FIELD: power industry.SUBSTANCE: nuclear reactor channel contains a pipe, fuel elements and neutron absorbers. The channel has second pipe inside the first pipe. Between the pipes the fuel assemblies are arranged, and in internal pipe the device for neutron absorber installation is located. At that the external pipe and the device for neutron absorber installation have bottom tips, on which respectively fuel assembly and neutron absorber rest being spring loaded, and the device for neutron absorber installation in top part by means of quick-release clamp is connected with rod with sealing assembly with channel external pipe.EFFECT: possibility of isotope unit reloading without the reactor power decreasing, reduced total number of channels and their reloading time.3 cl, 2 dwg
