The Phoebus II Reactor required a neutron absorber material for criticality control and a neutron poison material for reducing the flux peak at the forward end of the fuel element. Normal B{sub 4}C was chosen for the neutron absorbing material, and Cu was employed as the matrix.A feasibility study developed procedures for producijg uniform, dense, stable sheet material of Cu-20, 40, and 50 v/o normal B{sub 4}C. The procedures were, with only slight modifications, translated to production operation to yield sheet from which Phoebus II control plates and end poison plates were made
