On extrapolated endpoints in the two-group theory of neutron diffusion
The use of an extrapolated-endpoint boundary condition in criticality calculations is discussed from the point of view of two-group neutron-transport theory. The use of a single Milne-problem extrapolated endpoint is justified, from the lowest-order approximation to the transport-theory result, only for certain values of the material properties of a bare multiplying slab.
