Neutron propagation

It is outside the scope of this book to give a detailed account of neutron propagation theory. The interested reader should refer to standard books on nuclear reactor theory like those of Weinberg and Wigner [54], Bussac and Reuss [48], Lamarsh [55], etc. However, we think it is useful to review the basics of neutron propagation, so that schematic calculations of hybrid reactors can be understood and carried out. The most general theoretical approach is the Boltzmann equation.
