周期法测量启明星Ⅱ号散裂靶材料的反应性价值
|
摘要
为验证理论计算程序及相关核数据,将固体散裂靶材料放入ADS启明星Ⅱ号零功率装置(启明星Ⅱ号)的靶区内,采用周期法测量靶区内有、无散裂靶材料的反应性,从而获得净散裂靶材料对应的反应性价值,并与理论计算结果进行比较。结果表明,反应性价值的实验测量结果与理论计算结果符合较好,验证了理论计算的正确性。经实验验证的理论计算程序和核数据可用于ADS次临界反应堆的设计。
In order to verify the calculation codes and nuclear data,the solid spallation target was placed in the target area of Venus-Ⅱ ADS critical experimental assembly,and the reactivity was measured by the period method.The reactivity worth corresponding to the each target material was obtained by comparing the measured periods with and without solid spallation target,and then results were compared with the calculation values.The results show that the experimental results are in good agreement with calculated results,therefore validating correctness of the theoretical calculation.The validated calculation codes and nuclear data can be used in the sub-critical reactor design of the ADS in the future.
