Abstract

This paper summarises the results of an experimental campaign carried out at SIET on the ELSMOR facility built in 2022 to validate a decay heat removal system for the E-SMR. Based on the passive mechanisms of natural circulation, the system aims to dissipate the reactor decay heat to a water pool, using two heat exchangers: a plate-type one coupling the primary side to the secondary side, and a vertical tube one coupling the secondary side to the water pool. Such a system is considered to be the most effective passive system, capable of safely managing the SMR accident and accidental situations, and achieving long-term decay heat removal without the need for electricity or external inputs. A description of the primary and secondary loops of the plant is given, together with the installed instrumentation and data acquisition system. In addition, the paper summarises the tests performed in terms of test procedures, test type and associated objectives, test matrix, test results, achievements, and open issues.

ELSMOR 欧洲项目：基于板式热交换器的创新型衰变热量去除系统的实验结果

本文总结了SIET在2022年建成的ELSMOR设施上进行的一项实验活动的结果，该实验旨在验证E-SMR的衰变散热系统。基于自然循环的被动机制，该系统旨在将反应堆衰变热散发到水池中，使用两个换热器:一个是板式换热器，连接一次侧和二次侧，一个是垂直管式换热器，连接二次侧和水池。这种系统被认为是最有效的被动系统，能够安全地管理SMR事故和意外情况，并在不需要电力或外部输入的情况下实现长期的衰变热排出。介绍了该装置的一次回路和二次回路，以及安装的仪表和数据采集系统。此外，本文还从测试程序、测试类型及相关目标、测试矩阵、测试结果、取得的成果和有待解决的问题等方面对所进行的测试进行了总结。

期刊介绍： Science and Technology of Nuclear Installations is an international scientific journal that aims to make available knowledge on issues related to the nuclear industry and to promote development in the area of nuclear sciences and technologies. The endeavor associated with the establishment and the growth of the journal is expected to lend support to the renaissance of nuclear technology in the world and especially in those countries where nuclear programs have not yet been developed.
