Effects of Multiple Control Rods

Journal of Nuclear Science and Technology, 1969
In this paper is proposed a new method of calculation of the effects of multiple control rods. The reactor is divided into two parts—the uniform fuel region and the control rods. The sinks for both thermal and epithermal fluxes of the control rods are taken into account.
