Categorize the type of neutron source used in problems 32 through 43. For this purpose, use the flow chart as shown below and find the box that best matches the source of neutron used in the above problems. In this figure, 1-D for example, stands for neutron diffusion equation in a one dimensional medium.
problems 32
Consider a plane neutron source emittingSoneutrons/s⋅cm2in a nonmultiplying, infinite, homogenous medium. The material of the medium has high scattering and low absorption cross section for neutrons. Find an expression for neutron flux in terms ofDandLof the medium. [Hint: Solve Equation VIe.2.12 in the-direction withs= 0 subject to the boundary conditions given by VIe.2.15].
