Abstract
A filter for the removal by the exchange effect of fission products from the coolant, generally helium, of a nuclear reactor comprises a gas-tight duct containing at least one coil of corrugated metal strip, the coil being formed from two strip layers whose corrugations are mutually crossing.
Claims9
In a fission product filter for a hot reactor coolant gas, especially helium, comprising a gas-tight chamber traversed by said gas during circulation thereof along a path and containing a filter element composed of a material capable of retaining fission products from said gas by material-exchange interaction of said gas with said filter element, said filter element being formed with passages traversed by said gas, the improvement wherein said filter element comprises at least one coil body composed of two corrugated metal strips having crests in direct contact with one another and coiled together upon a core, the corrugations of the two strips mutually crossing where said strips contact one another in adjacent turns so that a zig-zag pattern of flow is established for said gas through said coil body and the passages are formed around the mutually contacting crests of adjacent turns.
