Abstract: MOX fuel pellets were prepared by bidirectional pressing. Through a series of experiments, the influence of pressing pressure, dwell time and addition amount of lubricants on the performance of fuel pellets was studied. A set of pressing technological parameters of fast reactor fuel pellet were obtained. The pressing pressure is 400 MPa, the dwell time is 2 s, and the content of zinc stearate is 0.4%. The results of the verification test show that the green billet made by the above process parameters is of good quality. The microstructure of the sintered pellets is uniform and there are no macro and micro defects, and the sintered pellets can be used in the manufacture of fuel pellets in fast reactor, and can be used as a reference for the manufacture of other types of fuel element pellets.
