摘要: 以某海域为例,初步探究某核设施正常运行时低放废液在中尺度海域的排放方案。采用MIKE21模拟软件,利用水动力模块(HD)和对流扩散模块(AD)建立了中尺度海域放射性核素迁移扩散数值模型,以半衰期为12.5年的放射性核素氚为例,考虑了排放口离岸距离、排放口方位和不利风向等因素,对放射性核素在中尺度海域的迁移分布状况进行了数值模拟。初步计算结果表明,排放口设在某河口东北侧,距岸不小于30 km的海域,有利于放射性核素的迁移、扩散。

Abstract: The low level liquid waste discharge scheme was studied with the normal operation of a nuclear facility in Jiangsu coast. A mesoscale radionuclide migration diffusion numerical model was established using the hydrodynamic (HD) and Advection-Dispersion (AD) modules of the simulation software MIKE21. The radionuclide migration and distribution of tritium at oceanic mesoscale were simulated in consideration of the distance from the shore, the sewage outfall azimuth, adverse wind direction, and other conditions. The preliminary results indicated that it would be advantageous to migration and diffusion of the radionuclide when the sewage outfall is set at the northeast location of the river mouth with no less than 30 km away from the shore.

Key words: low level liquid waste, MIKE21, numerical simulation, tidal field, radioactive nuclide, migration and diffusion
