TÜV Rheinland Achieves U.S. Recognition for SIL Certifications in Nuclear Industry Applications

(IN BRIEF) TÜV Rheinland’s Safety Integrity Level certifications are now recognized within the U.S. nuclear approval process following a joint audit by DAkkS and the Nuclear Energy Institute. This recognition allows manufacturers to use existing SIL-certified products in nuclear applications without undergoing additional redesign or repeated testing. Integrated into the Commercial Grade Dedication framework, the certification provides a streamlined pathway for qualifying industrial components for nuclear use. The change is expected to reduce approval times, lower costs, and improve market access for certified products. It also strengthens TÜV Rheinland’s position as a key certification body supporting companies operating in highly regulated industries worldwide.

(PRESS RELEASE) COLOGNE, 21-Apr-2026 — /EuropaWire/ — TÜV Rheinland has achieved a significant milestone as its Safety Integrity Level (SIL) certifications are now officially recognized within the United States approval framework for nuclear applications. This development follows a joint audit conducted by DAkkS and the Nuclear Energy Institute, placing TÜV Rheinland among a limited group of organizations whose certifications meet U.S. nuclear regulatory expectations.

SIL certification, based on the globally established IEC 61508, verifies the reliability and risk-reduction performance of safety-critical systems, including sensors, valve control mechanisms, and power supply components. With this recognition, manufacturers are now able to leverage their existing SIL-certified products for nuclear applications in the U.S. without the need for extensive redesign or repeated testing to satisfy additional nuclear-specific standards.

The acceptance is anchored in the Commercial Grade Dedication (CGD) process, a framework defined by the Nuclear Energy Institute and formalized under guideline NEI 17-06. This approach enables industrial-grade components to be qualified for nuclear use when they meet specific verification criteria. TÜV Rheinland’s SIL certifications can now be directly incorporated into this process, offering a structured pathway for transitioning products from industrial compliance to nuclear qualification.

This advancement is expected to deliver tangible benefits for manufacturers operating in the nuclear supply chain. By recognizing existing certifications, the process reduces approval timelines, minimizes redundant testing, and lowers overall certification costs. At the same time, products certified by TÜV Rheinland gain increased credibility within the regulatory environment, strengthening their competitiveness in U.S. nuclear projects.

With its established expertise in functional safety and certification aligned with IEC 61508, TÜV Rheinland is positioned to support companies seeking to expand into highly regulated sectors. The recognition further enhances its role in enabling manufacturers to deploy their technologies across global markets, particularly in industries where safety and compliance are critical.
