A GENERAL OPERATION PLAN OF HPR1000 NUCLEAR PLANT POWER INCREASE FROM 2% TO 25%FP BY AUTOMATIC CONTROLLER

Abstract

At this stage, digital technology and intelligent technology have been deeply developed, and the automation level of platforms and equipment can widely support the automatic operation of nuclear power systems. At present, the control systems of thermal power plants and other industries have been greatly improved in automatic operation, while the automatic operation of nuclear power plants has not been widely improved in terms of operation and maintenance of nuclear power plants. It is necessary to increase the research on automatic operation of nuclear power plants. For the normal start/stop process of nuclear power plants, automatic start/stop is an important part of improving the level of automation, which can significantly improve user experience, reduce start/stop time, improve the availability and economy of nuclear power plants, and effectively avoid human errors. During the start-up process, the operation of increasing plant power from 2% to 25% FP power is a key operation in the start-up process of the power plant. From the perspective of general operation requirements, this paper carries out a task analysis for the start-up process of increasing power from 2% to 25% FP power. The general framework and general technical scheme of self-starting operation provides a research direction for the design scheme of HPR1000 automatic start-stop under all working conditions.
