Abstract

803,701. Nuclear reactors. PARSONS & CO., Ltd., C. A. Oct. 18, 1956 [Aug. 11, 1955], No. 23225/55. Class 39(4). Ducts within the core 2 of a nuclear reactor contain a fluid with a neutron absorption that is varied to control the reactor. Where the fluid is an aqueous solution of a cadmium salt, this is supplied from a constant head mixing tank 5 to re-entrant tubes 1. Hot fluid leaving the core is cooled at 6 and stored in a reservoir 3. The neutron absorption is varied by variation of density, or level or pressure (gaseous fluids) in all or in selected tubes and thus the power output and/or the distribution of neutron flux may be controlled. Non-aqueuous liquids, including liquid metals, solid suspensions, and gases or mixtures of gases may be used.
