【摘要】：近年来随着海洋生态环境的变化,滨海核电厂经常发生海生物堵塞取水口的事件。目前国内核电厂在机组运行的时候,均以大海为最终热阱。如果取水口被堵塞,可能会造成机组因为冷却水不足而停堆或者降功率运行。因此,为了保障核电厂的运行安全,各滨海核电厂均对其取水工程进行安全改进,其中防海生物拦网的使用是其中一项重要的改进措施。介绍核电厂所需拦截海生物的分类情况,以及常用的防海生物拦网的种类。结合若干典型的核电厂防海生物拦网的实施情况,阐述防海生物拦网的选用和布置原则。
[Abstract]:In recent years, with the changes of marine ecological environment, marine biological blockage of water intake often occurs in coastal nuclear power plants. At present, the sea is the final heat trap in domestic nuclear power plants. If the intake is blocked, it may cause the unit to shut down or power down due to insufficient cooling water. Therefore, in order to ensure the operation safety of the nuclear power plant, all coastal nuclear power plants have carried out safety improvement on their water intake works, among which the use of anti-marine biological blocking network is one of the important improvement measures. This paper introduces the classification of intercepting marine organisms required for nuclear power plants and the types of commonly used anti-marine biological interceptors. Combined with the implementation of some typical marine biological blocking networks in nuclear power plants, the selection and layout principles of marine biological interceptors are expounded.
