OSTI ID:4840043
In many problems, where the diffusion equations are used, it is useful to replace a region, of a reactor for instance, by another geometrically simpler (usually circular). This method is frequently applied, in the calculations of a cell of a heterogeneous reactor, or of control rod efficiency. A way of evaluating the boundary conditions of the simplified region is presented, based on the equalization of averaged albedos. This procedure is rather fast if one possesses a code for computer calculations, which gives the albedos, or a quantity directly related to them (admittances). (auth)
