MODELING RELATIONSHIPS IN NEUTRON TRANSPORT THROUGH DUCTS AND CAVITIES.
Abstract
If radiation reflection within a duct or cavity is treated by the usual albedo approximation, that is, on the assumption that radiation emerges from the wall at the same point at which it is incident, it is possible to establish modeling relationships between similar configurations differing only by a scale factor. The foregoing assumption is investigated, and it is found that the modeling relationships are approximately valid for fission neutrons as long as the linear dimensions are on the order of two and a half feet or more. This lower limit may be decreased if the 'effective reflection plane,' which is always a few centimeters beneath the actual cavity interface, is utilized as the bounding surface of the duct or cavity.
