ABSTRACT:
A shield for a gas cooled nuclear reactor. The reactor vessel head is provided with two regions of material which act in synergism to reflect neutrons back to the core, attenuate gamma rays and neutrons, and allow heat recovery. The primary region attenuates gamma rays and provides significant neutron attenuation. The secondary region provides the residual neutron attenuation.
