This patent describes a neutron reflector assembly for the irregular space in a nuclear reactor between an array of rectilinear elongated fuel assemblies through which reactor coolant is circulated and a cylindrical core barrel surrounding the array. The neutron reflector assembly comprising: a plurality of modules each comprising a metallic mass and configured to collectively substantially fill the irregular space between the fuel assemblies and the core barrel; and mounting means separately supporting substantially the full weight of each module from the core barrel at only one point located near the upper end of each module. The modules being sized so that they are free to thermally expand in all directions from the mounting means.
