Abstract
A pressurized-coolant reactor fuel rod comprises a cladding tube having ends closed gas-tightly, the tube internally defining a fuel-containing space and in which nuclear fuel pellets are positioned. The tube contains a fission gas plenum chamber formed by a capsule having a flow choke connecting the chamber with the fuel, this capsule being positioned between the fuel and one of the tube ends closed gas-tightly. The capsule is made elastically expandable lengthwise with respect to the cladding tube and it engages and restrains the fuel against displacement lengthwise with respect to the tube, by elastically pressing the fuel away from the tube's closed end adjacent to the capsule.
