One Group Diffusion Model
摘要
In the previous chapter, we have assumed that the neutron source is given. This is not the case in the core of a nuclear reactor, since the fission source depends on the neutron flux. Mathematically, we obtain an eigenvalue problem that we shall be able to solve in a few particular cases. From such an eigenvalue problem, we shall be able to deduce a critical equation, at least in the homogeneous case.
