Nuclear power has advanced since the first self-sustaining chain reaction in 1942, achieving a record generation of 2667 terawatt-hours in 2024. Its primary application is in naval vessels, with the first nuclear-powered ship, the USS Nautilus, launched in 1954.

Attempts to develop nuclear aircraft and trains faced safety concerns and were ultimately abandoned. In space, the US, Russia, and China are investing in nuclear propulsion technology, aiming for demonstrations of nuclear thermal and electric systems in the next 5-10 years. However, safety and environmental regulations are essential as nuclear capabilities expand.
