NUCLEAR REACTOR
The core of a reactor is formed of one of more bodies of substantially non-porous material comprising a homogeneous mixture of fissile material and a solid moderator, to that the neutron temperature will increase simultaneously with an increase in moderator temperature. The reactor core may also have a homogeneous admixture of a material having a high neutron capture coross section dishat the absorption of neutrons by this material relative to the absorption of neutrons by the fissile material increases with temperature. Suitably this material has a large number of strong resonance absor ption bands at energies above thermal, the concentration of this material in the moderator being such that at least 3 percent of the neutrons are captured by resonance absorption. Preferably the reactor comprises a plurality of tubes, filled with the homogeneous mixture of solid moderator and fissile material, projecting into the coolant within a reactor tank, the tubes being spaced to provide passageways for the coolant circulation in the tank.
