Test fabrication of 'Joyo' fuel, (11)

Description

The fabrication of the initial-core fuel pellets of about 1200 kg mixed oxide fuel for Joyo has been completed. Though the specification was extremely severe, the fabrication was successful, except that uranium oxide spots were detected in some lots by autoradiography. Experiments showed that the spots were due to the existence of agglomerate particles. Homogeneous pellets, i.e. those without the uranium oxide spots, were able to be produced from uranium oxide powder by the application of calcination and reduction as pre-treatment. (Mori, K.)
