Frost Abstract: The diffusion of two volatile fission products, xenon (Xe) and krypton (Kr), in zirconia (ZrO) is investigated. Samples of Yttria (YO)-stabilised tetragonal ZrO were implanted with either Xe or Kr, at 300 keV, with a fluence of 1017 at./cm,
Abstract: Proton irradiation with a primary ion energy of 2 MeV was used to simulate radiation damage in UN and (U,Zr)N fuel pellets. The pellets, nominally at room temperature, were irradiated
