Development of Integrated Online Monitoring System for Tritium With Function of Discriminating HTO

摘要: 在氚的在线监测过程中，为实现对氚化水蒸气的甄别测量和高浓度时记忆效应的消除，本文研制了一种用于实验现场的氚监测系统。该系统采用模块化设计，主要由弱电流测量模块、数据处理模块、氚化水蒸气甄别模块和记忆效应消除模块等组成。性能测试结果表明，系统稳定性满足使用要求，且具备较高的氚化水蒸气甄别能力和彻底的记忆效应消除能力。

Abstract: During on line monitoring for tritium, in order to monitor both HTO and HT, and eliminate the memory effect at high concentration, the system was developed for monitoring tritium at tritium experimental site. The system was modular in design, and mainly consisted of a weak current measurement module, a data processing module, a tritiated water discriminating module and a memory effect eliminating module. The performance test shows that the stability of the system meets the requirement, the capacity for discriminating HTO is good and it can completely eliminate the memory effect.
