摘　　要：事故容错燃料(Accident Tolerant Fuel,ATF)自福岛核事件以来受到了广泛关注。以UO_(2)为代表的陶瓷基ATF因其高熔点、优异的抗辐照性能和化学稳定性等优势,是当前核燃料的研究主流。然而,陶瓷基ATF仍面临制备工艺复杂、成本较高等挑战。研究人员采用放电等离子烧结、闪烧等新型烧结技术制备陶瓷基ATF,在缩短烧结时间、降低烧结温度方面获得了进展。通过对UO_(2)基、UN基、U_(3)Si_(2)基、UC基等几种典型的ATF的烧结技术进行了分析归纳,探讨了不同烧结技术的特点和发展前景,并对未来开发ATF进行了展望。Since the Fukushima incident,accident tolerant fuel(ATF)has received widespread attention.Ceramic-based ATF,represented by UO_(2),has become the mainstream of nuclear fuel,due to its advantages such as high melting point,excellent radiation resistance,and chemical stability.However,ceramic-based ATF still faces challenges such as complex preparation processes and high costs.Progress has been made in shortening sintering time and reducing sintering temperature by adopting new sintering techniques such as spark plasma sintering and flash sintering to prepare ceramic-based ATF.This article is aimed to analyze and summarize the progress of sintering technology for ATFs based on UO_(2),UN,U_(3)Si_(2) and UC.In addition,the characteristics and development prospects of different sintering techniques will be discussed and the future development of ATF will be looked forward.
