| 摘 要： | 为开展ADS系统的中子学设计研究,选择和建立了一套基于离散坐标方法的计算软件。采用IAEA基准题对该软件系统进行了检验。在此过程中,了解和完善了对该软件系统的使用。该文对于起始时刻(BOL),对基准问题作了包括Keff,所需散裂中子源源强,功率密度分布,能谱指标分布和空洞效应等计算。对燃耗过程计算了各个核素(锕系元素和裂变产物)核密度的时间、空间分布。计算结果用表格和图表示。结果与国外的计算基本相符。结论认为这套软件系统可用于ADS系统的优化设计研究。

| Abstract: | To study the neutronics for the ADS system, a set of computation softwares based on discrete ordinate method is selected and established. The set is tested through an IAEA benchmark. In the test process, the understanding and using of this software set are improved. The benchmark is analyzed. The calculations include the effective multiplication factor keff the required strength of the spallation neutron source for 1.5 GW thermal power, the distribution of power density and the spectrum index, and the void effect at the beginning of life, BOL; the spatial and time-dependent density distribution of various nuclides ( actinides and fission products ) for burn-up process. The results are given in figures and tables and are consistent with calculations made abroad. The conclusion is that this software set can be applied to the optimization of design study for the ADS system. |
