Abstract

This paper describes the application of the Source-Jerk method using a neutron generator in the VR-1 reactor. The experiments were carried out on a shutdown reactor with subcriticality greater than -10 βeff. A D-D neutron generator located in the radial channel of the VR-1 reactor was used as an external neutron source for the Source-Jerk method. The obtained results were discussed and compared with a conventional Source-Jerk method used at the VR-1 reactor and with the values calculated by the Serpent 2 code. The presented experimental works and their results will allow to extend the methods of reactivity measurements on the VR-1 reactor. They will also help to optimise reactivity measurements on the new subcritical reactor VR-2, which is currently being commissioned at the Czech Technical University in Prague.

在亚临界反应堆中应用使用中子发生器的源-杰克法

本文介绍了在 VR-1 反应堆中使用中子发生器的源-Jerk 方法的应用。实验是在亚临界度大于 -10 βeff 的停堆反应堆上进行的。位于 VR-1 反应堆径向通道中的 D-D 中子发生器被用作源-杰克法的外部中子源。对所获得的结果进行了讨论，并将其与 VR-1 反应堆使用的传统源-Jerk 方法以及 Serpent 2 代码计算的值进行了比较。所介绍的实验工作及其结果将有助于扩展 VR-1 反应堆的反应性测量方法。它们还将有助于优化新的次临界反应堆 VR-2 的反应性测量，该反应堆目前正在布拉格捷克技术大学投入使用。

期刊介绍： Acta Polytechnica is a scientific journal published by CTU in Prague. The main title, Acta Polytechnica, is accompanied by the subtitle Journal of Advanced Engineering, which defines the scope of the journal more precisely - Acta Polytechnica covers a wide spectrum of engineering topics, physics and mathematics. Our aim is to be a high-quality multi-disciplinary journal publishing the results of basic research and also applied research. We place emphasis on the quality of all published papers. The journal should also serve as a bridge between basic research in natural sciences and applied research in all technical disciplines. The innovative research results published by young researchers or by postdoctoral fellows, and also the high-quality papers by researchers from the international scientific community, reflect the good position of CTU in the World University Rankings. We hope that you will ﬁnd our journal interesting, and that it will serve as a valuable source of scientiﬁc information.
