| 摘 要： | 提出一个燃烧高放超铀废物的思路，即在外部聚变中子源驱动下，把燃烧超铀锕系元素和钍铀燃料循环相结合.并且设计相应的一维模型，使用开发的燃耗计算程序ONESN_BURN和新制作的数据库对模型进行计算和分析.通过计算，得到锕系元素的放射性，生物潜在危害因子，高放超铀锕系废物的密度和非常深的燃耗深度等.比较聚变裂变混合堆与传统的热堆，发现中子能谱越硬，对燃烧超铀锕系元素越有效.

| Abstract: | We propose a method of burning high-level transuranic waste combining with Th-U fuel cycle in a subcritical reactors driven by external fusion neutron sources. Corresponding one-dimension model is built by means of ONESN_BURN code with new data libraries. Numerical results, including actinide radioactivity, biological hazard potential, and high burn-up rate of high-level transuranic waste are obtained. Comparison with thermal reactor shows that the harder neutron spectrum is the more efficient than the soft one. |
