摘要
核电站反应堆冷却管道疲劳问题是核电站老化管理关注重点之一,特别是当核电站服役年限渐长、定期安全审查(PSR)、电站申请延寿时,核监管机构要求核电站必须提供相关的信息以验证疲劳对部件的损伤影响程度。通过对目前核电站疲劳监测系统的调研,分析了主流疲劳监测系统的功能、相关的参数及彼此间的差异性。
The fatigue problem for primary circuit of nuclear power plants （NPPs） is one of the key focus on aging management, especially when nuclear power plant＇s service life grows, or the nuclear regulators require nuclear power plants to provide relevant information to verify the fatigue damage of components when the NPPs apply periodic safety review （PSR） and life extension. In this paper, an investigation on the fatigue monitoring systems was carried out, and the fatigue monitoring system functions and parameters related to the differences between each other were com-pared, in order to provide information for the selection or independent research and development of the monitoring system for NPPs in the future.
