| 摘 要： | 压水堆核电厂一回路冷却剂中的部分氚会通过废液和废气排放系统排放至工作环境中。本文报道某压水堆核电厂辐射控制区气态氚的监测结果:运行期间气态氚浓度范围为<LLD～9.21×102 Bq/m3;大修期间为<LLD～3.14×103 Bq/m3。监测结果显示,压水堆核电厂运行初期工作环境中氚浓度较低,工作人员在现场工作无需采取额外的防护措施以及进行氚内照射剂量监测。

| Abstract: | Some tritium in the primary coolant circuit of a pressurized water reactor can be discharged into the working environment through liquid waste and gas emission systems. The monitoring results of vaporous tritium in the controll area of a PWR nuclear power plant is presented. It comes out that, during operation and outrage, the concentration of vaporous tritium was <LLD-9.21×102 Bq/m3 and <LLD-3.14×103 Bq/m3 , respectively. This indicates the tritium concentration in the initial working environment is relatively low, and there is no need to take additional protective measures for working stuff and conduct tritium internal dose monitoring. |
