| 摘 要： | 铀尾矿库退役后要进行环境治理和长期监测,对库中放射性核素进行模拟可以为放射性废物安全管理提供科学依据.笔者采用有限元法对尾矿中238U在地下水中的迁移情况进行了模拟,结果表明,尾矿库治理后1 000 a,238U迁移到距尾矿库边缘183 m的地方,未到达附近河流.

| Abstract: | Environmental treatment and monitoring must be done after decommission of uranium mill tailing impoundment. Simulation of radionuclides migration will be given for safety management of radioactive wastes. This paper demonstrated the migration of ^238 U in groundwater which is simulated by using finite element method. Resuits show that the migrating distance of ^238U is 183 m at the time of 1 000 years after rehabilitation. |
