THE RESEARCH OF AUTOMATIC OPERATION FUNCTIONAL REQUIREMENTS OF EMERGENCY PROCEDURES ON AIR-COOLED MICRO REACTOR

抄録

As the fourth-generation advanced reactor, the air-cooled micro reactor has the characteristics of modularity, high inherent safety, high level of automatic control, and non-dynamic safety design. The origin of the accident is clear, and the accident handling methods are concentrated, which greatly simplifies the emergency operation strategy. In order to further reduce the burden on operators and improve the automation level of the reactor, the research is develop on the automated implementation of emergency operation procedures. On the basis of ensuring nuclear safety, based on the characteristics of the core and auxiliary system of the air-cooled micro-reactor, the functional requirements of the automated execution system of accident procedures are put forward from the design principles, interface display, basic functions, etc.. In this research, the requirements for the entry method of the procedures, the display of the procedures, the rights management of the procedures, and the operation of the procedures are given, and relevant examples are given for some of the requirements. According to the functional requirements of the research, the current emergency operation procedure strategy can be transformed to have the ability of automatic implement. The transformed procedure system can meet the requirements of regulations, has friendly man-machine interface, and has relatively high automatic execution ability.
