Abstract
1,067,136. Controlling reactors. HITACHI SEISAKUSHO KABUSHIKI KAISHA. June 24, 1964 [June 24, 1963], No. 26151/64. Heading G6C. A thermal fission reactor comprises a reactor core surrounded by a neutron moderatorreflector, control elements containing fertile material or a combination of fertile and fissile material arranged around the core in the reflector or in a space between the reflector and the core, and control means to vary the effective surface area of the control elements. The control elements function as shielding of the reflector, low power corresponding to a virtual absence of reflected thermal neutrons in the core, and high power corresponding to a normal proportion of reflected neutrons. The fertile material may be thorium 232, uranium 238 or plutonium 240. The reflector is preferably heavy water. The control element effective surface area is varied either by rotating the plates to place them edge-on to the flux leakage path, or by withdrawing them bodily from the core vicinity. It is preferable for the core to produce a large neutron leakage, to obtain control over a wider range. A second reflector region may be employed between the control elements and the core, and the density of this reflector varied by introducing voids or changing temperature.
