Abstract

The behavior of helium implanted in sintered uranium dioxide disks has been investigated as a function of annealing temperature. UO₂ disks have been implanted with 1 MeV ³He at a nominal fluence of 5 × 10¹⁶ ³Hecm^-2 using a Van de Graaff accelerator. The ³He(d,α)¹H nuclear reaction analysis method was used to determine the helium depth profile in the UO₂ disks. Partial flaking was observed after annealing at 500 °C for local He concentration of 1 at.%. After annealing at 600 °C flaking has affected the whole surface. The formation of helium bubbles is discussed.
