ABSTRACT:
A fuel pellet retainer spring assembly is disclosed for insertion to the open unsealed end of a fuel rod. The assembly includes a locking sleeve having a normal radial diameter exceeding the inside radial diameter of the fuel rod cladding. This sleeve is compressed to a diameter less than the inside diameter of the fuel rod cladding. Thereafter, the sleeve is inserted. In the preferred embodiment, a washer and coil spring precedes the sleeve into the fuel rod. The sleeve is inserted and thereafter allowed to expand and frictionally hold to the inside wall of the cladding. When the sleeve is in place, the coil bears against the inside portion of the radial sleeve and forms the surface from which a fuel pellet biasing spring maintains fuel pellets within the unsealed fuel rod.
