Abstract
Voids in the core of a nuclear reactor have an important effect on neutron leakage from the reactor. It is important that this effect be taken into account in computing the critical mass of the reactor. It is also frequently desirable to know the effect of empty channels on the neutron distribution outside the core.
In the present paper we consider the effect of a single hollow cylindrical channel on neutron diffusion. Expressions are obtained for neutron leakage through a channel located at the center of the reactor and for the additional neutron leakage (due to the existence of the channel) in the immediate vicinity of the channel. We also consider the effect of the neutron flux distribution along a channel on the applicability of the diffusion formulas.
