Framatome signs contracts with Sizewell C
French nuclear developer Framatome is slated to deliver key equipment for Sizewell C Ltd.’s two large reactors planned for the United Kingdom’s Suffolk coast.
The agreement, reportedly worth multiple billions of euros, was announced this week and will involve Framatome from the design phase until commissioning. The company also agreed to a long-term fuel supply deal. Framatome is 80.5 percent owned by France’s EDF and 19.5 percent owned by Mitsubishi Heavy Industries.

Most nuclear power plants (NPPs) under construction or under design are expected to deploy largely digital instrumentation and control (I&C) systems. Current fleets are increasingly looking toward converting to digital I&C systems due to the advantages of precise control, economic operation, and ease of procurement over conventional analog I&C systems. With all the benefits digital I&C systems bring, challenging cybersecurity concerns are introduced as well. Cyberattacks targeted at industrial control systems have grown in both frequency and capability in recent years. Despite efforts to air-gap digital I&C systems, NPPs can be vulnerable to these cyberattacks, as evidenced by recent cyber incidents at nuclear facilities. Cybersecurity of NPPs should be addressed in three complementary thrusts: cyberattack prevention, detection, and response. Considering the requirements of digital I&C systems, we propose a novel cybersecurity solution platform that consists of a data collection and extraction system, a multilayer cyberattack detection system, a cause analysis system with dynamic risk assessment, a cyberattack response system, and a main control room display system. This architecture also promotes cooperation between information technology experts and the operation technology team to improve cybersecurity by integrating process data together with traditional host system and network data in a unified platform. This paper presents the proposed cybersecurity architecture and demonstrates its efficacy with a simulated cyberattack on a cyber-physical system testbed. Together with traditional intrusion prevention methods and rule-based intrusion detection systems, this platform provides a solution for prevention, detection, and response to cyberattacks that is congruous with the defense-in-depth strategies of other NPP safety and security systems.
