May 10, 2023 – Framatome announced new contracts with Vattenfall for the modernization of the Swedish Ringhals nuclear power plant. Per the agreement, Framatome will update reactor control systems using its proven digital instrumentation and control (I&C) TELEPERM XS platform and refurbish the reactor coolant pumps for Units 3 and 4.
“Framatome’s continued dedication to extending the life of critical nuclear facilities is a core focus of our mission,” said Bernard Fontana, CEO of Framatome. “Today’s agreement is a step forward in strengthening our long-standing relationship with Vattenfall and our commitment to support the continued operations of safe, economical, reliable and low carbon electricity generation at Ringhals.”
Framatome will modernize the plant’s reactor control system using its TELEPERM XS digital I&C platform. The modernization also includes the upgrade of the KSU Simulator at Ringhals. Prior to installation, the equipment will be jointly tested with Vattenfall at KSU Simulator premises. The new reactor control system will be installed and commissioned in 2026 for Unit 3 and in 2027 for Unit 4.
In addition to the control system upgrades, Framatome will also refurbish six reactor coolant pumps (RCPs). Within the primary loop, RCPs are fundamental to the safety and efficiency of nuclear power plants. Framatome has manufactured, maintained and repaired these components for decades from its Jeumont and Maubeuge industrial facilities in northern France.
The RCP internals and motors will be transported to Maubeuge, where they will be inspected and refurbished, including the installation of new stators and the replacement of thermal barrier covers. The refurbished elements will then be shipped back to Sweden to progressively replace the current operating equipment starting 2025 through 2031.
Ringhals nuclear power plant has been in commercial operation since 1976 and is located about 60 kilometers south of Gothenburg on the west coast of Sweden. The power plant has two pressurized water reactors and produces around 17 TWh of electricity annually.
