Nuclear Solutions

SEL maintains exclusive partnerships with two of the nuclear power industry’s most trusted companies—Framatome and Curtiss-Wright Nuclear—who are authorized to qualify and support our products for safety-related nuclear applications.

The SEL partnership with Framatome and Curtiss-Wright marks a step-change in the nuclear power industry. Now, for the first time in the 40+ years that digital protective relays have been on the market, a full line of intelligent electronic devices is available for safety-related applications.  

Our partners have long track records of implementing industry standards and guidance, as well as navigating the regulatory requirements for evaluating and dedicating digital relays. Each has devoted significant effort to testing and documenting SEL products to verify that they meet the rigorous requirements of the nuclear industry.

Framatome and Curtiss-Wright Nuclear qualify SEL devices for safety related nuclear applications in these areas and more:

• Differential protection
• Feeder protection
• Generator protection
• Motor protection
• Transformer protection

Each of our partners has the same access to SEL products and technologies and works closely with us on technical support and service. Choose the company that best meets your needs.

Together, SEL and the integrator of your choice will 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—will perform commercial-grade dedication, including all aspects of testing, documentation, and compliance necessary to implement SEL products in all levels of safety-related and quality-related nuclear systems.

The integrator will obtain the proper SEL product and qualify it for your application in accordance with the engineering change package and may also be contracted to install and commission the complete system, if desired.

After the system is operational, the integrator and our nuclear partners work with SEL to provide ongoing technical support for all SEL devices.

Upgrading electric power protection and control systems from electromechanical and solid-state relays to modern digital protective relays brings 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.

IEDs and network communications offer improved operational flexibility and reliability—but they also bring cybersecurity concerns.

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 operational technology 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.
