摘要
寒冷地域核电站低温防冻问题,是我国核电领域一个新的研究方向。本文对北方核电站低温防冻设计中关键的若干问题,逐一进行了系统分析,提出了解决对策。分析了低温海水引发的问题,比如引起核岛的重要厂用水系统、常规岛冷却水系统结冰等。针对低温海水引发的问题,简介了国内外核电站采取的两类方案(取水口热水回流、前池热水回流)。分析了低温空气引发的室外、室内低温防冻问题。冷空气通过直接或间接作用的方式,使系统、设备、仪器等处于低温状态,出现介质结冰、材料性能变化、材料热应力变化等现象,影响其正常功能的发挥。针对低温空气引发的室外、室内低温防冻问题,分别作了详细的对策分析。分析了事故状态下的低温防冻问题,在研究事故状态下的低温防冻常规解决方案基础上,提出了非核应急供热系统。
It's a crucial problem for the nuclear power plants in the northern region of China that freezing may occurred during its operation in cold weather condition.Some key issues were systematically studied,which include how to prevent the ice formation in the entrance of sea water,what anti-freezing methods must be accepted in face with extreme cold weather condition,what it will be for the power plants if any accidents happened during chilled winter.Emergent heat station for the nuclear power plants was discussed.
