Modular radial neutron reflector.

摘要

A neutron reflector assembly for the irregular space (13) in a nuclear reactor between an array (5) of elongated rectilinear, fuel assemblies (3) through which reactor coolant is circulated and a cylindrical core barrel (7) surrounding the array, consists of a plurality of modules (15) each including an elongated strongback (21) and a plurality of elongated plates (23) jointed along their longitudinal edges to form an elongated enclosure (17) having neutron reflectors disposed therein for insertion into the irregular space (13) between the fuel assembly array (5) and the cylindrical core barrel (7).
