摘要
为进一步进行燃料元件故障监测技术研究,开展了燃料元件破损在线监测装置在HFETR上的试验研究工作。本文对试验结果进行了讨论与分析,发现了"碘坑"现象和启堆时135 Xe中毒现象,这两个现象都与理论分析结论一致。同时也将装置监测的结果与实验室取样测量结果进行对比,发现装置的监测结果与实验室测量结果符合较好。试验研究表明,燃料元件破损在线监测装置具备了在一回路水复杂环境下连续跟踪目标核素进行定性及定量监测的能力,具备了在实际工程应用能力。
In order to study the technology of fuel element rupture monitoring further, the test of the online monitoring device for fuel element rupture on HFETR was done. This paper described the test results and analysis. The iodine well phenomenon and xenon poisoning phenomenon were found, and there were agreed with theory. Moreover, the monitoring results of the prototype also accord with laboratories results. So the test results confirmed that the device have a ability of monitoring target nuclides in primary loop.
