Abstract
A heat-insulating lining for a fast reactor shield slab comprises a set of panels each consisting of a mat of superposed wire mesh or fabric elements enclosed within at least one metallic casing which is secured against the shield slab. The end walls of the casing are formed by sealing plates applied against the panels and the side walls are formed by at least two interengaged L-section members so arranged that one flange of each member covers the edge of one sealing plate whilst the other two flanges leave a narrow lateral gap which forms a capillary seal.
Claims8
In a fast nuclear reactor, a heat-insulating lining for a shield slab which serves to close the biological shield structure of said fast reactor comprising an open tank mounted within the shield structure and containing the reactor core immersed in a mass of liquid-metal coolant and a layer of inert blanket gas which is present above said coolant, said heat-insulating lining being comprising a set of panels each constituted by a mat of superposed elements of metallic fabric or trelliswork extending parallel to the shield slab to be heat-insulated, wherein the set of panels is enclosed within at least one metallic casing fixed against the shield slab and so arranged that the end walls of said casing which are parallel to the panels are formed by sealing plates applied against said panels, the sides of the casing which connect the sealing plates to each other being constituted by at least two interengaged L-section members having two flanges at right angles, one flange of each member being adapted to cover one sealing plate whilst the other two flanges delimit therebetween a narrow lateral gap forming a capillary seal.
