Abstract
An element for a core of a nuclear reactor, includes a square grid assembly formed of a plurality of spacers distributed over the length of the element, structural elements interconnecting the spacers, rods regularly disposed in the square grid assembly and surrounded by the spacers, including a plurality of the rods disposed at an edge of the core, and neutron-shielding material having a substantially square cross section respectively disposed in each of the plurality of rods at the edge of the core.
Claims8
Neutron shielding assembly of a reactor core assembled from nuclear reactor fuel assemblies and neutron shielding assemblies, comprising a square grid assembly formed of a multiplicity of spacers distributed over the length of the assemblies and structural elements interconnecting said spacers defining inner and outer rows, and respective rods orderly disposed in said square grid assembly and surrounded by said spacers, said rods of said nuclear reactor fuel assemblies being individual cylindrical fuel rods and said rods of said neutron shielding assemblies being metal rods with square cross sections, and said neutron shielding assemblies disposed at an edge of the reactor core having additional metal rods with square cross sections attenuating neutron radiation emanating from the periphery of the reactor core, the additional metal rods lying at least in one of said outer rows of the neutron shielding assembly.
