Nuclear propulsion refers to the use of nuclear reactions to generate thrust for propulsion in vehicles, primarily in the context of spacecraft and naval vessels. There are two main types of nuclear propulsion systems: 1. **Nuclear Thermal Propulsion (NTP)**: In this method, a nuclear reactor is used to heat a propellant (typically hydrogen) to high temperatures. The heated propellant is then expelled through a rocket nozzle to produce thrust.
