ABSTRACT:
A neutron absorbing panel has improved resistance to loss of efficiency resulting from bending about an axis located at a designated side of the panel. The panel comprises a core of substantially uniform thickness formed of a sintered mixture of particles of neutron absorbing material such as boron carbide (B.sub.4 C) and metal such as aluminum. Metal cladding sheets are provided at both sides of the core, and aluminum is the preferred metal for both the metal core particles, and cladding. The sintered core lacks the ductility of the outer cladding sheets, and to improve bendability, the thickness of one cladding sheet is materially greater than the other. Bending of the improved panel about an axis spaced outwardly from the side thereof having the thinner cladding sheet leaves the outer surface of the panel at the bend smoother than when the cladding sheets are of uniform thickness, and substantially uniform neutron absorbing ability is retained.
