针对横流式自然通风冷却塔工艺设计存在的问题，提出相应的改进措施，包括核心设备结构、模拟计算方法、防冻及降低噪音方案的改进。对核电站使用大型横流式冷却塔进行了技术、经济性分析。结论：横流式冷却塔应用于核电站是可行的，在大型核电站中其优势尤为明显。

According to problems occurring in the process design for the cross-flow natural draft cooling tower, the improvement measures are put forward including the key equipment structures, simulated calculation approach, freeze-proofing and reductions in noise et al. Furthermore, the technical and economic analysis is carried out for the application of large cross-flow cooling tower on the nuclear power station. It is concluded that the cross-flow cooling tower applied in the nuclear power plant is feasible, of which the advantage is particularly evident in the large nuclear unit.
