聚变实验装置稳态运行和假设事故释放氚的环境影响分析研究
Environmental Impact Analysis of Tritium Release during Steady-State Operation and Hypothetical Accidents in the Fusion Experimental Devices
摘要
Abstract
Deuterium-tritium(D-T)fusion is anticipated to be the earliest commercially viable controlled fusion reaction.However,the use of radioactive tritium poses environmental and radiological risks to hu-mans.To evaluate the exposure hazard to the nearby public from tritium leakage into the atmosphere under both steady-state operation and hypothetical accidental conditions of the D-T experimental devices,a dose assessment code was developed based on the steady-state Gaussian plume model and Gaussian multi-puff model.By combining gaseous deuterated water release data from the ITER safety report with ECMWF re-analysis meteorological data for the Shidao Bay Nuclear Power Plant in China and ITER sites for the year 2023,public exposure from tritium-containing air via inhalation and skin absorption was calculated.The re-sults indicate that the maximum public doses in the vicinity of the ITER site and the Shidao Bay site during steady-state operation are 0.018 mSv/yr and 0.0304 mSv/yr,respectively,significantly below the 0.1 mSv/yr dose limit proposed by the ITER project.Under accidental conditions,the re-emission of tritium becomes significant,necessitating consideration of its subsequent migration between environmental elements.关键词
