ABSTRACT:
A fuel rod for a nuclear reactor fuel assembly includes a metal cladding tube having two closed ends. A column of nuclear fuel pellets is disposed in the cladding tube. A compression spring has helical coils and is coaxial with the column of pellets within one of the ends of the cladding tube. A shim has two sides and is disposed between the column of pellets and the helical spring. A pair of leaf springs on one of the sides of the shim is locked to and biased against the coils of the helical spring.
