氚育种是聚变核技术的重要组成部分。氚增殖比大于1是自给自足燃料所必需的。为了模拟14 MeV的D-T聚变中子输运，推荐用蒙特卡罗程序和逐点核数据进行三维真实感模拟。连续能的黎波里-4蒙特卡罗输运程序在辐射屏蔽、临界安全和裂变反应堆物理中得到了广泛应用。为了支持ITER用Tripoli-4程序进行的TBM(试验包层模块)中子学研究，本文用Tripoli-4模拟了大阪大学6个OKTAVIAN球面组件：Li、Li-C、Pb-Li、Pb-Li-C、Be-Li和Be-Li-C的氚增殖率，并研究了核数据库对ENDF/B-VI.4、ENDF/B-VII、Jeff-3.1、JENDL-3.3和FENDL-2.1计算的影响。总体而言，的黎波里-4产生了令人满意的C/E值。只有Jeff-3.1文库中的铍引入了较高的不确定度。
Tritium breeding is an essential element of fusion nuclear technology. A tritium breeding ratio greater than unity is necessary for self-sufficient fueling. To simulate the 14MeV neutron transport in tritium breeding systems from the D–T fusion reaction, the 3D realistic modeling with Monte Carlo code and the point-wise nuclear data are recommended. Continuous-energy TRIPOLI-4 Monte Carlo transport code has been widely used on the radiation shielding, criticality safety, and fission reactor physics. For supporting the ITER TBM (test blanket module) neutronics study with TRIPOLI-4 code, this paper presents the TRIPOLI-4 simulation of TBR (tritium breeding ratio) for six OKTAVIAN spherical assemblies of Osaka University: Li, Li–C, Pb–Li, Pb–Li–C, Be–Li, and Be–Li–C. It also investigates the impact of nuclear data libraries on TBR calculations from ENDF/B-VI.4, ENDF/B-VII.0, JEFF-3.1, JENDL-3.3, and FENDL-2.1. In general, TRIPOLI-4 produced satisfactory C/E values. Only beryllium of JEFF-3.1 library introduces higher uncertainties.
