Abstract

Versions of the neutron source multiplication (NSM) method are considered. The method developed at foreign research institutes to determine the reactivity of deeply subcritical reactors uses reactivity of the “reference” level. Further, the results of the use in the above methods and in the area ratio method of the computational experiment simulation technique that yields sufficiently precise data without involving the reference level are discussed. The practicability of applying the method of the computational experiment simulation to the versions of the neutron source multiplication methods used at some institutes of Russia in the procedure of critical mass experiments is validated.

用中子源相乘法和面积比法测量的亚临界水平的绝对值

摘要

考虑了中子源倍增（NSM）方法的版本。国外研究机构开发的用于确定深亚临界反应堆反应性的方法使用了“参考”水平的反应性。此外，讨论了在上述方法中以及在不涉及参考水平的情况下产生足够精确的数据的计算实验模拟技术的面积比方法中的使用结果。验证了将计算实验模拟的方法应用于俄罗斯一些研究所在临界质量实验过程中使用的中子源倍增方法的可行性。
