Abstract

An advanced radial core neutron reflector RCR is provided for a nuclear reactor core. The RCR comprises a minimal number of tiers and employs a number of improved restraint mechanisms to provide vertical and horizontal support of the RCR. Specifically, the RCR has four tiers, a bottom tier which functions as a foundation that is precisely aligned and secured with an improved dowel and fastener arrangement, two intermediate tiers, and a top tier. A spigotting staircase-type geometry is employed to radially secure abutting, adjacent tiers. At least the intermediate tiers are segmented into quadrants to facilitate making of the RCR, and a clamping assembly secures the seams between quadrants. One or both of a keying or an alignment pin assembly secures the interfaces between tiers, and a secondary vertical support may be employed at the top tier.
