便携式氢表在核电站中的应用

摘要

核电站功率运行期间和换料大修前，需监测反应堆冷却剂系统的氢含量。本文介绍了用ORBISPHERE 3654型便携式氢表快速测量反应堆冷却剂中氢含量的实验过程及便携式氢表在宁德核电站的应用情况。结果表明，便携式氢表能快速准确地测量RCP中的氢含量，测量的最佳水流量为270～310 mL/min。%During nuclear power plant operation and overhaul ,the hydrogen concentration in reactor coolant system is subject to monitoring .This paper mainly describes the experimental process of rapid measurement of hydrogen in reactor coolant system by using portable ORBISPHERE 3654 hydrogen meter and the application of portable hydrogen meter in Ningde nuclear power plant .The results show that the portable hydrogen meter can rapidly and accurately measure hydrogen content in the RCP with optimal water sample flow at a rate of 270-310 mL/min .
