The paper represents overview of modern instrumentation and control (I&C) systems intended for use in nuclear power plants (NPPs), including their functions and main objectives. Possible application of Field Programmable Gates Array (FPGA) technology for I&C of NPPs is discussed. Experience of RPC Radiy in development and modernization of digital I&C systems is presented, along with implementation of FPGA solutions for NPPs in I&C modernization projects.
