某压水堆核电厂辐射控制区氚化水蒸汽监测

Abstract

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.

Key words: PWR nuclear power plant, Controll area, Tritiated steam
