GSO IEC 61250:2014 核反应堆 重要的安全设备和控制系统 冷却剂系统中的泄漏检测的最新版本是哪一版?
最新版本是 GSO IEC 61250:2014 。
This International Standard defines the requirements for instrumentation needed to detect leakage from reactor coolant systems of light water nuclear reactors. Methods of leak detection are described, and characteristics of different methods of detection and of differentiating between allowable and abnormal leakages are given. The sensitivity of systems required to ensure early detection of developing leaks and to give warning of possible leak-before-break situations is considered, and recommendations are given to reduce spurious alarms. Recommendations are given for data display which will allow presentation in a clear and concise manner to enable operators to take appropriate actions to minimize the risk of hazard to plant equipment and to personnel. The requirements are given for recording and logging, as well as for summation of individual signals to detect trends. The object of this standard is to define the requirements for leakage detection data, for arranging it in a logical manner, and for displaying information to enable the operator to take appropriate action. A secondary objective of this standard is to standardize criteria, methods and procedures for assuring the design and operational adequacy of the reactor coolant and associated systems (RCAS) leakage detection systems used in light water cooled nuclear reactors.
事实上,全美所有核电站已经执行了新规定中的两条:一是要求核电站在2001年911恐怖袭击之后加强对安全设备的保护,并安装足量的设备,以同步支持相关核反应堆;二是要求核电站安装更先进的设备,从而检测每个核反应堆废燃料库里的水位。 第三是要求全美所有的热水核反应堆增强第一代和第二代密闭结构。...
他认为,压力容器、安全壳等设施的完好,是非常重要的。 从核反应堆的构造来看,前两者都是核燃料的保护设备。也就是说,它们的稳固,可能会使得整个核反应堆的泄漏在控制范围之内。 该核电专家向记者解释,沸水堆一般会有一个压力容器、两层安全壳。与国内AP1000第三代核反应堆有一层安全壳的构造有所不同。当然,“沸水堆”型与法国EPR的核反应堆两层安全壳类似。 ...
美国麻省理工学院的核工程师迈克·格雷说:“你必须接受这样的事实:有些事会超出系统的处理能力。” 今天,核反应堆的设计理念是“深度防御”。这种方法要求不会同时失灵的多重系统和不同技术。罗尔斯顿说,动力丧失是福岛核电站的主要问题之一,也是工业研究最多的情境之一,因为动力丧失将导致冷却剂的无力推进,从而无法将热量从反应中导出。...
