本文介绍了核聚变-裂变混合能堆包层分析模型中积分中子实验的最新进展。混合反应堆的概念包层主要装载天然铀和锂材料。在裂变燃料区，铀材料和轻水交替排列。设计了概念包层的实物模型，并通过积分实验对包层的中子特性进行了检验。根据现有材料，用于裂变研究和钚生产的球形裂变模型由三层贫铀壳和几层聚乙烯和石墨壳组成。用于生产氚的球形锂模型由贫铀和LiPb合金壳组成。该立方体模型由天然铀和聚乙烯组成，其结构与燃料区基本一致。在D-T中子源的模型中，分别测量了钚的产生率、铀的裂变率和氚的产生率。利用MCNP-4B代码和ENDF/B-VI库数据，将实测结果与计算结果进行了比较。
The paper describes recent progress in integral neutronics experiments in the analytical mockups for the blanket in a fusion-fission hybrid energy reactor. A conceptual blanket of the hybrid reactor is mainly loaded with natural uranium and lithium material. In the fission fuel region, uranium material and light water are arranged alternately. The mockups of the conceptual blanket are designed and used for checking neutron property of the blanket by integral experiments. Based on materials available, the spherical fission mockup for fission research and plutonium production consists of three layers of depleted uranium shells and several layers of polyethylene and graphite shells. The spherical lithium mockup for tritium production consists of depleted uranium and LiPb alloy shells. The cubic mockup consists of natural uranium and polyethylene and its structure is basically consistent with one of the fuel region. In the mockups with the D-T neutron source, the plutonium production rates, uranium fission rates and tritium production rates are measured, separately. The measured results are compared to the calculated ones with MCNP-4B code and ENDF/B-VI library data.
