Nuclear reactor fuel rod
Abstract
Abstract A nuclear reactor fuel rod formed of a cladding tube, end caps hermetically sealing the tube at both ends thereof, the tube being divided transversely into two longitudinal zones one of which is for receiving a charge of nuclear fuel and the other of which is for receiving gas-adsorbing material free of nuclear fuel, includes means received in the second zone for simultaneously supporting the tube and for containing gas-adsorbing material therein, the means having a capsule having an open end facing toward the one zone and a gas-permeable member closing off the open end of the capsule, the capsule containing adsorber material that has been dried and degassed in high vacuum at temperatures of from 500° to 1000° C, the capsule having an interior space between the adsorber material contained therein and the gas-permeable element, and including a metallic foil destructible by a given internal pressure of the fuel rod gas-tightly closing the interior space; and method of production.
