应用隐显方向交替法计算广东核电站海区流场、温度场和浓度场数值模拟是二维的．在广东核电站正常运转情况下，预测附近海域水质变化的规律．研究结果表明：低温废热和低放废水排入海区后，放射性物质浓度在排放口周围水面积约４ｋｍ２以外海区已接近或低于天然本底值；温度差在排放口周围水面积约６ｋｍ２的范围以外已低于０．５℃，对水生生物和周围环境不会发生有害的影响．
Applying the hidden direction alternating method to calculate the flow field in the sea area of Guangdong Nuclear Power Plant, the numerical simulation of temperature field and concentration field is two-dimensional. Under the normal operation of Guangdong Nuclear Power Station, the law of water quality changes in the vicinity of the sea area is predicted. The results show that after low-temperature waste heat and low-level waste water are discharged into the sea, the concentration of radioactive material is close to or below the natural background value at a water area of about 4 km 2 around the discharge opening. The temperature difference is about 6 km 2 around the discharge opening Other than below 0.5 ℃, no harmful effects on aquatic organisms and the surrounding environment will occur.
