Inside a Nuclear Submarine Breath, Water and Atomic Power

Beneath the ocean, nuclear submarines are self-contained cities. This documentary explains, in clear, research-based terms, how submarines generate breathable air from seawater, produce fresh water, run compact nuclear reactors for years, and use layered safety systems to avoid meltdowns.
We cover: electrochemical oxygen systems and CO₂ scrubbing, desalination from reactor heat, reactor design and control systems, passive safety features, crew life-support routines, and why decades of naval practice have made these vessels remarkably safe.
