中文摘要:
      由于经验和技术缺失,我国冰区滨海核电站的冷源取水安全受到海冰的威胁。数值模拟预警是建立和完善核电冷源取水安全保障系的关键部分。本文以辽东湾东岸的红沿河核电站为例,介绍了 3 种主要的核电冷源安全海冰致险模式,给出了 不同致险模式的数值模拟预警流程,并对数值模拟范围的选取进行重点阐述。结果表明,满足 24 h 预警需求的海冰数值模拟范围面积在数百甚至数千平方公里以上,较大的模拟范围与高网格分辨率对运算能力提出了较高的要求,是目前该数值模拟预警需要解决的突出问题。
英文摘要:
      Due to the lake of experience and technology, the safety of sea water intake of Chinese nuclear power plants in ice zone are under threaten of sea ice. Numerical simulation warning play an important role in establishing and improving the security system for water intake of nuclear power plant. With a case study of the Hongyanhe Nuclear Power Station, which locates in the east coast of the Liaodong Bay, three main sea ice threatening modes to the safety of water intake of nuclear power plant are introduced in this paper. Then the process framework and implementing plan of the numerical simulation warning for the three main threatening mode are shown. What's more, the simulation range of numerical simulation warning is expounded. As the result show, an area of hundreds and thousands of square kilometers is needed for the numerical simulation warning with forecast period of 24 hours, which means massive grid. Now, the big simulation range and high grid resolution leads to high demand for computing power, which become a striking problem in numerical simulation warning.
