Abstract
A process for manufacturing nuclear radiation shields consisting of neutron-absorbing boron carbide particles embedded in a heat-dissipating copper matrix. Copper is electroplated through a layer of loose, electrically nonconductive boron carbide particles on a metal substrate. The carbide particles may be deposited on the substrate while electroplating, and heat exchanger ductwork may be incorporated. To make cylindrical shields, a cylindrical metal substrate is rotated about its axis giving rise to centrifugal forces which hold the carbide particles on the inner surface and aid electrodeposition. A thermomechanical process is described in which boron carbide particles pre-encapsulated with copper are consolidated into a unitary mass on the inner surface of a heated cylindrical substrate with or without the aid of a roller within the cylinder.
