Information Security Risk Analysis and Countermeasures of Digital Instrumentation Control System in NPP

Abstract

Under the background of actively adjusting energy structure, promoting energy conservation and emission reduction, and enhancing energy security capability, the rapid development of nuclear power has become an inevitable trend. As a national high-security technology, nuclear power is directly related to the interests of the country. In recent years, with the deep integration of nuclear power plants (NPPs) and information technology, the information security of NPPs has become increasingly important. The digital instrument control system is a typical representative of the integration of NPPs and information technology. The paper mainly analyzes and evaluates the information security of the digital instrument control system of NPPs, and discusses the countermeasures. This paper analyzes the systems, equipment and components that may have information security risks in the digitized instrument and control system of NPPs, and puts forward countermeasures and management measures for new and operational power plants in view of the possible information security risks.
