Framatome has been selected to carry out a major modernisation of digital control systems at the Columbia nuclear power plant, operated by U.S. utility Energy Northwest. The French company will design, manufacture, test and install a new generation of control systems for several essential components, including feedwater level regulation and the drainage and ventilation functions of feedwater heaters.
Technological upgrade of safety systems
The planned work involves integrating an advanced version of the Tricon digital system, a commercial-grade control platform designed to ensure the safe and stable operation of reactors. This system, integrated into the plant’s instrumentation and control (I&C) framework, serves as a key interface between operators and the plant’s automated safety functions. It provides continuous monitoring and enables immediate response in the event of a malfunction.
The upgrade is expected to enhance operational reliability while reducing long-term maintenance costs. By improving the readability of critical information, the proposed solution aims to support better operator decision-making during routine operations and exceptional situations.
Localised production and industrial impact
The manufacture and assembly of the new components will take place in the United States, at Framatome’s operational centres in Mansfield, Massachusetts, and Lynchburg, Virginia. This locally anchored industrial approach will reduce logistical delays and centralise testing and quality assurance operations within certified facilities.
Tony Robinson, President and Chief Executive Officer of Framatome in North America, stated that the contract “reflects a growing partnership with Energy Northwest” and marks a further step in the continuous improvement of U.S. nuclear fleet performance. A detailed implementation schedule has not yet been disclosed.
