MOX燃料在国外已成功应用于轻水堆和快中子增殖堆中。Pu元素的放射性和毒性给MOX燃料芯块制造技术带来很大不便。本文通过对U-Ce-O系统、U-Pu-O系统的热力学性质、相图等方面的比较和对制造工艺的模拟方式进行的初步探讨表明,在MOX燃料的生产工艺试验中,U-Ce-O系统可用来模拟U-Pu-O系统。
MOX fuel has been successfully applied to light water reactor and fast neutron multiplication reactor in foreign countries. The radioactivity and toxicity of Pu elements have brought great inconvenience to MOX fuel pellet manufacturing technology. Through the comparison of the thermodynamic properties and phase diagrams of the U-Ce-O system and the U-Pu-O system and the preliminary study on the simulation of the manufacturing process, this paper shows that in the MOX fuel production process test, the U- The Ce-O system can be used to simulate U-Pu-O systems.
