Description
An out of pile experiment was performed on the corrosion of the SiC layer by fission product Pd in the Triso-coated fuel particles of high temperature gas-cooled reactor. In order to clarify the corrosion mechanism, influence of Pd activity on the corrosion was studied. Seven Au-Pd alloys with different Pd contents were prepared and simulated TRISO-coated particles were heated in the powder of the alloys at 1473 and 1573K. The Pd-SiC reaction zones were observed and analyzed by XMA. From the experimental results, the reaction rate was found to be dependent on Pd activity. The dependence of the reaction rate on temperature and time was also discussed. (author)
