ln a cylindrical reactor an arbitrary number of safety rods were completely inserted parallel to the axis. For the determination of the reactivity change caused. eigenvalue equations were derived for possible rod configurations with the help of the two-group theory. Special value is therefore placed on the mathematically satisfactory consideration of the boundary conditions at the surface of the safety rod. Using the Karlsruhe research reactor FR-2 as an example, the eigenvalue equations for air-fllled. H/sub 2/ Ofilled, and D/sub 2/O-filled cadmium rods were evaluated as a function of the uniform rod radius. The numerical results were compared with corresponding results obtained within the one-group theory. (tr-auth)
