ABSTRACT:
A system for producing neutron pulses seriatim in which a smaller, high velocity, sub-critical, downward traveling slug intercepts a larger downward falling sub-critical target-mass, both of which have a portion of higher concentration in fissile materials. The combined masses are more than prompt-critical and the resulting neutron and energy pulse is contained within a large pressure vessel. Spray of mostly sodium slurry protects the walls of the vessel from the effects of the neutron and energy pulse and absorbs the energy and neutron excess of the energy-neutron pulse. Heated slurry is drained from the pressure vessel to provide useful heat energy and neutron irradiated materials. Precipitated materials and sodium are used in the fabrication of both the slug and target-mass.
