FPGA Technology and Platforms for NPP I&C systems

This chapter describes an element base of new generation for NPP I&C, namely field programmable gate array (FPGA), and peculiarities of the FPGA application for designing safety critical systems. FPGA chips are modern complex electronic components that have been applied in nuclear power plants (NPPs) instrumentation and control systems (I&CSs) during the last 15-17 years. The advantages and some risks caused by application of the FPGA technology are analyzed. Safety assessment techniques of FPGA-based I&CSs and experience of their creation are described. The FPGA-based platform RadICS and its application for development of NPP I&CS is described.
