Analysis of use
Advantages
- Higher ISP than chemical
- Higher power energy source
- Shorter travel time
- Oberth effect
- Self cooling
Disadvantages
- Cost
- Cost of development
- Risk of accident
- Lower ISP than electric
- Low public trust
- Thrust to weight ratio usually lower than 1 (cannot take off from a planet)
Types
- Solid core
- Gas core
- Nuclear light bulb, open and closed
