Abstract

Abstract

HPR1000 is one of the 3rd generation nuclear power plants in China. The fatigue monitoring and transient counting system is an important monitoring system in HPR1000, which plays a positive role in the safe and economical operation of HPR1000. Nuclear Power Institute of China has developed a fatigue monitoring and transient counting system with independent intellectual property rights. The system consists of 25 temperature measuring components, a signal processing cabinet and a computing workstation. The models for thermal inverse problem, green function stress calculation, coolant environmental fatigue calculation, and transient counting have been developed, which allow the functions of monitoring the fatigue state of the primary system and automatically identifying and counting the running transient. Through the development of principle prototype and engineering prototype, the related key technologies have been solidified through verification, and the technology is mature and has engineering application conditions.
