Abstract
The absorption and the transport effect in a channel within the reflector of a reactor has been already studied with the first group theory, this study will discuss its resolution with the second group theory which describes the neutron distribution within a reactor by the value of two functions representing respectively the flux of fast neutrons and thermal neutrons, S{sub f} and S{sub s}. The study of the reactivity variation caused by a disturbance in the critical conditions and its application to the effect of a radial channel located within the reflector of a reactor leads to the evaluation of the reactivity drop caused by the presence of radial channels in the fully charged EL3 reactor. Numerical results are given for the contribution of the fast neutron and thermal neutron flux to the reactivity drop as well as the expression of the reactivity drop caused by the neutrons transport effect.
