BPE 510 consists of polyethylene loaded with 30% boron. It is an
effective thermal neutron poison; containing 1.8 x 1022 boron
atoms per cc. BPE 510 is available in slabs, bricks, rods, and
cylinders. BPE 510 can thus thermalize the neutrons via fast
neutron collisions with hydrogen atoms, then absorb the
thermalize neutrons via absorption by the boron atoms. This
process is effectively accomplished because of the high
densities of B.
BPE 510 is radiation shielding is especially useful for the
control of criticality. Control of criticality is of utmost
importance during all phases of power reactor fuel handling,
including reprocessing. In order to assure neutron isolation
during these stages, materials containing high concentrations of
boron are frequently used.
