【摘要】 针对核动力舰船的环境特点,采用吸附介质为乙二醇与无氚水混合液(体积比为1:1)的被动式取样器来监测密闭核动力装置中HTO的浓度。在不同的工作场所连续监测1个月,该取样器的最大相对偏差小于10%;将该取样器与硅胶作为吸附介质的被动式取样器进行为期1 a的对比实验,测量误差小于6%。结果表明,该取样器能准确地测量到低浓度的HTO,满足密闭核动力装置中HTO的监测需求。更多还原

【Abstract】 According to the environmental characteristics of nuclear power ships, a passive sampler with a volume ratio of ethylene glycol to tritium-free water of 1:1 is used to monitor the concentration of tritiated water in a closed nuclear power plant. After continuous monitoring for 1 month in different work places, it is found that the maximum relative deviation of the sampler was less than 10%; Sampler has been compared with the passive sampler with silica gel as the adsorption medium for 1 day comparison experiment, and the measurement error is less than 6%. Results show that the sampler can accurately measure the low concentration of HTO, which meets the monitoring requirements of HTO in closed nuclear power plants.更多还原
