PWR TYPE REACTOR

A mechanical spectral shift reactor comprises a reactive core (34) having fuel assemblies (32) accommodating both water displacer elements (40) and neutron absorbing control rods for selectively changing the volume of water-moderator in the core (34). The fuel assemblies (32) with displacer and control rods are arranged in alternating fashion so that one displacer element drive mechanism (36) may move displacer elements (40) in more than one fuel assembly (32) without interfering with the movement of control rods of a corresponding control rod drive mechanisms (38).
