Physics Tests to Verify Performance of Vanadium Detectors of Qinshan Pressurized Heavy Water Reactor after First Replacement

随着钒探测器中子辐照时间的增加,探测器的灵敏度将降低,甚至失效。因此,在运行一定时间后,需要进行钒探测器的整体更换。文章主要对CANDU6反应堆钒探测器首次更换后相关物理验证试验的设计与实施展开讨论和分析。通过验证和分析,最终结果符合要求。

With the increasing of neutron irradiation time, the sensitivity of the vanadium detectors will reduce and even lose efficacy. Therefore, the vanadium detectors need to be integral replaced after operating a certain period of time. This paper mainly discusses and analyzes the design and implementation of the physics tests to verify the performance of the vanadium detectors of the CANDU6 reactor after replacement for the first time. The results meet the requirements through the analysis and verification, lying an important foundation for the safe and stable operation of the plant in the future and providing an important reference for the similar work in the future.
