摘要

如今,对具有广泛应用的新型 SMR 反应堆(通常被归类为第四代新型反应堆)的需求日益增长。遗憾的是,目前还没有商业运行的核反应堆在技术设计和功能上符合第四代反应堆的特征。第四代核反应堆正在全球范围内得到大力开发,捷克共和国也不例外。至少有两个通用的第四代热中子反应堆概念使用石墨作为慢化剂或反射器,许多非常流行的小型模块化反应堆概念也是如此。为了支持与这些反应堆开发相关的研究活动,需要一个适当的实验环境和资源,模拟使用石墨的第四代反应堆的预期条件。计算得出的数据证实了之前研究获得的结果。由于额外的石墨反射层和中央石墨塞,在 LR-0 进行的石墨反射器实验对反射器中的中子通量分布得出了更好的结果。此外,该堆芯布置已被纳入一套实验中,以支持对带有石墨反射器的反应堆堆芯的研究。这篇文章的主要目的是为第四代反应堆开发新的中子仪器功能样本提供支持。

Special Experimental Environment for Gen. IV Reactors with Graphite Reflector
Nowadays, there is an increasing demand for new SMR reactors with a wide range of applications, often classified as a new generation IV. reactors. Unfortunately, there is no commercially operating nuclear reactor meeting the characteristics of Gen. IV reactors in its technical design and features. Gen. IV nuclear reactors are intensively developed worldwide, including the Czech Republic. At least two general Gen. IV thermal neutron reactor concepts use graphite as a moderator or reflector, as do many concepts of the very popular small modular reactors. To support research activities linked with the development of these reactors, an appropriate experimental environment and resources simulating conditions expected in Gen. IV reactors with graphite are needed. The calculated data confirm the results obtained during previous research. The experiment at LR-0 with a graphite reflector gives better results of neutron flux distribution in the reflector due to the extra graphite reflector layer and central graphite plugs. Besides, the core arrangement is included in a set of experiments supporting the research of reactor cores with graphite reflectors. The main reason for this article is to support the development of a new functional sample of neutron instrumentation for Gen. IV reactors.
