The Paul Scherrer Institute (PSI) in Switzerland, and the Commissariat a l'Energie Atomique (CEA) in France, collaboration on advanced nitride fuel has concentrated on a program of comparative experimental irradiation of (U,Pu)N fuel in the PHENIX Fast Reactor. The two parties have undertaken studies to ensure the success of the experiment. The PSI work has been mainly carried out for uranium nitride and the PSI gelation process has been applied to mixed nitride. CEA has successfully produced hybrid microsphere pellets from the press feed supplied by PSI and also developed the dry powder metallurgy route to obtain high-density pellets. The principal test of a sphere-pac and hybrid sphere-pellet fuel irradiation experiment in comparison with dry route pellets is thus making good headway.
