This patent describes a neutron reactivity control system for a LWBR incorporating a stationary seed-blanket core arrangement. The core arrangement includes a plurality of contiguous hexagonal shaped regions. Each region has a central and a peripheral blanket area juxapositioned an annual seed area. The blanket areas contain thoria fuel rods while the annular seed area include seed fuel rods and movable thoria shim control rods.
