Consistency requires that one neutron is as important as its progeny. From these ideas, the adjoint equations and boundary conditions are derived for the Boltzmann transport model, for simple and multigroup diffusion theory and for the continuous slowing-down model. This more general concept for the time-dependent importance includes the conventional expressions of iterated fission probability, etc. as special cases.</p></div>","PeriodicalId":100813,"journal":{"name":"Journal of Nuclear Energy.

It is also often of interest to know how empty channels affect the manner in which neutrons diffuse out of the core. The effect of a single hollow cylindrical channel is considered herein. Expressions are derived for the neutron leakage along a channel through the centre of the reactor and for the additional losses in the vicinity of the channel arising from the presence of the channel. The way the form of the flux distribution along the channel affects the applicability of diffusion formulae is considered.</p></div>","PeriodicalId":100813,"journal":{"name":"Journal of Nuclear Energy.
