摘要
A hermaphroditic absorber exploits the inherent spatial change in the neutron spectrum within a lumped poison mass in a thermal reactor neutron flux field. The hermaphroditic absorber (poison mass) incorporates two types of absorbers, the first being a strong thermal absorber near the surface of the mass, and the second being a strong resonant absorber in the interior of the poison mass. The outer regions of the poison mass are comprised of a strong 1/v thermal absorber, and the inner region of the poison mass is comprised of a resonance absorber. This resonance absorber more appropriately exploits the hardened characteristics of the neutron spectrum within the absorber mass by selectively absorbing the epi-thermal neutrons. The creation of the hermaphroditic poison mass permits an increase in the control material worth while maintaining the external dimension of the structure containing the control material, such as a BWR control rod.
