Framatome inks contract with ČEZ to Modernize Instrumentation and Control Systems

February 14, 2023 – Framatome announced today it has signed a contract with ČEZ to modernize the existing instrumentation and control (I&C) Spinline testers for safety systems installed on four VVER type reactors at Dukovany Nuclear Power Station, located in Czech Republic.

“We commend ČEZ for its high standards of safety and vigilance in fortifying the long-term operations of one of its largest, most reliable and economically advantageous energy sources,” said Frédéric Lelièvre, senior executive vice president, Sales, Regional Platforms and the I&C Business Unit at Framatome. “Our teams will deliver this project with the level of commitment to safety and operational excellence that is the foundation of our strong and long lasting relation with ČEZ.”

Framatome’s engineering specialists will redesign, manufacture, validate and install the new Spinline testers. The first installation is planned mid-2024 during the Dukovany-2 planned outage. This project is the first step in the comprehensive modernization of the existing Spinline safety I&C platform that will allow ČEZ to operate Framatome systems until 2045.
