摘要: 本文针对阳江核电站50 km核应急计划区的阳江海域,采用切比雪夫谱方法计算了阳江海域的潮流速度和潮位值,进而采用粒子随机行走模型,模拟计算了阳江核电站正常工况下,液态流出物10 h连续排放后,阳江海域内核素氚的浓度分布。计算结果表明,核素迁移扩散24 d后到达海陵岛附近海域,此时有氚分布的区域常规相对浓度值低于0.005,活度浓度值低于0.70 Bq/L,该值与海陵岛海水氚的监测活度浓度(<0.97 Bq/L)量级上相符。此结果表明,阳江核电站液态流出物中的核素氚对阳江海域环境无明显影响。

Abstract: Based on Yangjiang sea area, Chebyshev spectral method was used to calculate the tidal velocities and sea levels, and particle random walk model was adopted to simulate the concentration distribution of radionuclide 3H from liquid effluent of Yangjiang nuclear power plants. The calculated results show that the concentration of radionuclide 3H is smaller than 0.70 Bq/L near Hailing Island in Yangjiang sea area, which is coincident with the measured value 0.97 Bq/L in October 2015. The result indicates that there is no obvious impact on the Yangjiang sea area due to liquid effluent from Yangjiang nuclear power plants.

Key words: calculated simulation, liquid effluent, Yangjiang nuclear power plants
