From retrofits and system modernization to next-generation projects, like advanced reactor installations, nuclear power generation demands solutions that are reliable and secure.Power plant modernization improves reliability and operational flexibility by deploying digital devices that offer better protection speed, increased functionality, secure data collection, and remote monitoring capabilities. Digital protective relays are easier to maintain than electromechanical devices and provide event reports that facilitate the analysis of power system disturbances, helping prevent failures and reduce operation and maintenance costs.New nuclear construction—especially microreactors and small modular reactors (SMRs)—needs to include power management and control solutions that manage balance-of-plant generation and control the utility interconnection. In addition, metering solutions help analyze and improve power quality on the grid.

- A comprehensive portfolio of digital protective relays that provide reliable protection for feeders, generators, motors, and transformers.
- Power management and control solutions for balance-of-plant generation and grid interconnection of both traditional nuclear sites and advanced reactor installations.
- Secure data collection, networking, and remote monitoring by using rugged automation controllers, industrial computers, security gateways, and cybersecure network switches that are purpose-designed for operational technology (OT) applications and have a service life measured in decades.
- Advanced revenue meters and power quality monitors that provide insight into the health of your electric power system and help integrate next-generation nuclear resources with the grid.
- Trusted partnerships with integrators Framatome and Curtiss-Wright Nuclear, who qualify SEL relays for nuclear applications and can install and commission complete systems.
How SEL and the Integrator Work for You
Together, SEL and the integrator of your choice ensure that your modernization and upgrade projects meet regulatory requirements and achieve your operating objectives.The nuclear integrator works closely with SEL and is your first point of contact throughout the entire lifecycle of your solution.One of our partners—Framatome or Curtiss-Wright—performs commercial-grade dedication, including all the aspects of testing, documentation, and compliance necessary to implement SEL products in all levels of safety-related and quality-related nuclear systems.The integrator obtains the proper SEL product and qualifies it for your application in accordance with the engineering change package. You could also contract the integrator to install and commission the complete system, if desired.After the system is operational, the integrator and our nuclear partners work with us to provide ongoing technical support for all SEL devices.See Our Partners’ Solutions
Modernizing Nuclear Safety-Related Systems
Upgrading electric power protection and control systems from electromechanical and solid-state relays to modern digital protective relays offers many benefits:
- Improved operational flexibility—One SEL digital relay can provide the functionality of several electromechanical relays.
- Increased reliability and availability—Digital relays require less time out of operation for repair and maintenance.
- Lower lifetime cost of operation—Monitoring the health and performance of power system components helps increase operational efficiency and prevent expensive equipment failures.
- Technical support—SEL provides responsive support and service for the entire lifecycle of our devices.
Cybersecurity
Cybersecurity has been a primary consideration at SEL ever since we introduced the first microprocessor-based digital relays to the market in 1984, and we continue to lead the electric power industry in developing OT systems that maximize both cybersecurity and ease of operation.We thoroughly test the source code in our devices to ensure their quality, security, and functionality. Source code is continually monitored for new threats, and customers are notified of updates and security patches for the full service life of every SEL product.
