Proven by 8 Nuclear Submarines

Over the span of 80 years of operation, eight lead-bismuth-cooled nuclear submarines demonstrated unwavering safety, even enduring severe accidents under extreme operational demands without succumbing to fire or explosions. These submarines revealed deep-rooted safety resilience. Challenges faced by the submarines—corrosion of structural materials, polonium radiation leakage, and the solidification of metallic coolants—were all overcome through groundbreaking research and development, ensuring the future of this technology.
