Abstract
The three dimensional problem of a reactor with partially inserted control rods is reduced to a two dimensional problem by a redistribution of control material within the reactor. The transformation is exact when the pitch circle radius of the rods and the depth of insertion of the rods into the reactor are large compared with the control rod pitch. The effect of variations in pitch on the accuracy of the transformation is investigated by calculation.
