FUEL ASSEMBLY OF A NUCLEAR REACTOR ON FAST NEUTRONS WITH A LIQUID METAL HEATER

摘要

The utility model relates to the field of atomic energy and can be used in fast neutron reactors. The technical result is to improve the thermohydraulic and neutron-physical characteristics of the reactor core. To achieve this, a fuel assembly of a fast neutron nuclear reactor with a liquid metal coolant containing rod fuel elements mounted in a hexagonal cover is proposed, while a screw with holes for fuel elements is placed in the cover. The screw is made of a sheet of steel twisted into a spiral, the outer part of which has the shape of a hexagon corresponding to the inner surface of the steel cover, and is rigidly connected to it. 1 s.p. f-ly, 4 ill.
