【摘要】 运用Visual modflow建立三维地下水流场,选用某砂岩介质的核电厂址,模拟3H在其中的迁移。模拟结果表明:3H在砂岩介质迁移速度较慢,约经过8 a其浓度峰迁移到河流中。3H在水平方向以迁移为主,在垂直方向迁移很小。更多还原

【Abstract】 This paper describes the visual modflow that was used to build a three dimensional groundwater flow field for simulating the waste tank with3H leakage at a NPP site in case of an accident. The results show that the migration of3H in geological condition is slower and it need 8 years for its peak of concentration to get into river. The migration of3H is dominant in horizontal direction and minor in vertical direction.更多还原
