Abstract The computerized procedures in high temperature gas-cooled reactor(HTGR)nuclear power plants need to be carefully monitored to efficiently control the operating characteristics of multiple nuclear steam supply system modules with one steam turbine. A normal execution process model and an interrupted variant execution process model were developed for HTGR power plants using the improved colored Petri net modeling method. The models were shown to accurately monior the execution of the computerized procedures. An analysis of a typical abnormal operating procedure for an HTGR plant shows that the modeling and verification based on the colored Petri net is effective and provides a theoretical foundation for the development of HTGR control systems.
