Safety Assessment of FPGA Based RPS System for Lungmen NPP

This paper proposes a tool and method to assess the validity of the FPGA based RPS system for Lungmen NPP by using the full scope engineering simulator. Accident scenarios and abnormal conditions will be inserted into the engineering simulator in order to activate the functions of the FPGA based RPS. Plant component malfunctions including individual hardware failure and software common cause failures will be inserted into the engineering simulator for safety assessment. Partial and complete failure of the FPGA based RPS scenarios will also be inserted into the engineering simulator in order to assess the degree of adequacy of the diversity and defense in depth (D3) design on safety-related fully computerized instrumentation and control systems for the Lungmen NPP.
