Title: Automatic closure device for adjusting the rate of flow of gases, adapted to avoid dragging of nuclear fuel elements by the gas stream
IPC: G21C19/04
Filed: 1965-06-15
Abstract: 1,081,188. Reactors. SNAM S.p.A. June 15, 1965 [June 18, 1964], No. 25339/65. Heading G6C. In a gas-cooled, graphite moderated, nuclear reactor the fuel elements rest in vertical fuel channels and are supported at their lower ends on movable members which throttle the gas flowing into the fuel channels. Each fuel element is formed of separate lengths arranged coaxially, vertically in each fuel channel. As a fuel element is unloaded, while the reactor is running, the removal of the separate lengths in turn reduces the total weight of the remaining length of the fuel element which would then tend to be ejected vertically through the upper outlet of the fuel channel by the upward gas thrust. This is prevented by the movable members supporting the fuel, which progressively throttle the coolant gas flow through the fuel channels as the fuel weight upon them is reduced. The members incorporate spring shock-absorbers.
