本实验是在中国科学院上海原子核研究所的铀—水栅零功率实验装置上完成的。所用燃料组件是为秦山300MWe压水堆核电站零功率堆物理实验时所用的15×15核燃料组件。而钍元件是直径为φ8毫米的铝包壳四氟化钍(ThF_4)棒,可根据实验要求把铀和钍棒混列在一起,组合成五种不同水铀比(即2.051、2.225、2.490、2.827、3.080),以及中心一组钍元件条件下的外推临界和超临界周期内插,边界元件当量的实验测量工作。对实验结果进行了理论校算,取得了比较满意的结果。
The experiment was performed on the uranium-water gate zero-power experimental set-up of Shanghai Institute of Nuclear Research, Chinese Academy of Sciences. The fuel assembly used for Qinshan 300MWe PWR nuclear power plant zero-power reactor physical experiments used 15 × 15 nuclear fuel assemblies. The thorium component is a φ8 mm diameter aluminum cladding thorium tetrafluoride thorium (ThF_4) rod, uranium and thorium rods can be mixed according to the experimental requirements, combined into five different water uranium ratio (ie, 2.051,2.225,2.490 , 2.827, 3.080), as well as experimental measurements of extrapolated critical and supercritical periodic interpolations and boundary element equivalents under a central set of thorium elements. The experimental results of theoretical calculations, and achieved satisfactory results.
