启明星1号装置中子通量能谱与中子平均能量计算

Calculation of Neutron Flux Spectrum and Average Neutron Energy for Venus 1^# Assembly

摘要: 启明星1号装置是我国研究ADS次临界中子学的一个快热耦合系统。本文用离散坐标法的程序TWODANT对启明星1号装置能谱进行分析计算。计算结果表明，启明星1号装置具有比较硬的中子能谱，可用以进行有关ADS的研究。

Abstract: Venus 1^# assembly is a system consisting of both fast and thermal neutron zones for ADS research in China. The neutronics spectrum calculations in Venus 1^# assembly were performed with twodimensional transport code TWODANT. The result shows that the neutron spectra in Venus 1^# assembly are hard enough for the ADS experiments.
