中文摘要：
聚变裂变混合堆在增殖核燃料、嬗变长寿命核废料及固有安全性等方面具有较大优势,同时,它比纯聚变堆在工程及技术方面要求低,因此较聚变堆更易实现。本工作基于目前国际聚变实验堆（ITER）所能达到的技术水平,提出一种直接利用乏燃料进行发电的聚变裂变混合堆包层概念,利用在不同位置放置不同乏燃料体积分数的方法对燃料增殖区实现了功率展平。计算结果表明：功率展平后的包层功率不均匀系数更小,且包层中燃料区的能量输出要比不展平情况下的能量输出高约21.7%。燃料富集度到运行末期最大可达5.23%。从中子学角度初步论证了该包层的可行性。
英文摘要：
The hybrid fusion-fission reactor has advantages of breeding of the nuclear fuel and transmutation of the long-life nuclear waste and having inherent safety.Meanwhile,the engineering and technological demand of hybrid reactor is significantly reduced comparing with that of pure fusion reactor.A generating electricity blanket concept using the PWR spent fuel directly was proposed,which was based on ITER parameter level achieved.Different volume fractions of the fuel in blanket enabled to realize a power flattening in the fissile zone.The results show that the peak-to-average power factor becomes less than no power flattening,and the output power of the fuel zone raises more than 21.7%.At the end of the operation,the maximum fuel enrichment is 5.23%.The blanket is feasible from the neutronics viewpoint.
