摘要: 福岛事故后,核电厂地下水环境影响评价逐渐成为人们关注的焦点。本文针对某内陆核电厂,基于地下水模型系统GMS,对某厂址及其附近区域地下水进行三维数值模拟,并对重要核素H-3、Cs-137和Sr-90在地下水中的迁移行为和影响范围进行预测和评价。结果表明:一旦发生放射性废液泄漏事故,H-3迁移速度较快,会影响厂址及其附近区域地下水,但不会对厂址北部河流造成影响;Cs-137和Sr-90迁移速度缓慢,影响范围仅局限在泄漏点周围100 m范围内,不会造成厂外影响。

Abstract: Environmental impact assessment of groundwater for nuclear power plant has been a focus after the Fukushima accident. TA three-dimensional numerical simulation to the groundwater at an inland nuclear power plant site was carried out using GMS. Prediction and assessment were then made to the migration mode and influence scope of key radionuclides including H-3, Cs-137, and Sr-90. Results show that H-3 with a relatively fast speed might have an effect on the site, but would not contaminate the river in the north. However, Cs-137 and Sr-90 transported so slowly that they could merely migrate less than 100 meters, had no effect on off-site.

Key words: inland nuclear power plant, groundwater, GMS, radionuclide migration, numerical simulation
