Summarized here is an attempt to utilize gadolinium as a burnable poison for total reactivity control of a PWR core equilibrium cycle, i.e., control without a soluble poison system. In the course of the research, a few design guidelines evolved: 1) gadolinium can be utilized well in the form of a lumped poison rod; 2) the optimal gadolinium rod is an annulus of gadolinium immersed in water; 3) BP rods are inserted into vacant thimble guide tubes; and 4) only fresh fuel assemblies are loaded with BP rods, thus avoiding insertion of the BP clusters into irradiated fuel assemblies.
