Reusable Rocket with Nuclear Energy

Why companies like SpaceX not using a sustaining and more efficient energy like Nuclear in its reusable rocket, instead they use Liquid Oxygen to fuel and then send the booster back on earth.

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

Well, that would be good way to sustain energy if you only consider the output, but building reactors in every reusable rocket will cost a lot. It has to be small enough to put in it. Also, the risk would be higher.

Actually, I think you have to define 'nuclear energy'. Nuclear energy could mean 'nuclear engines', or ' nuclear reactor that generates electricity'. I'll take it as the first definition. Mechanism of an nuclear engine is basically heating up liquid hydrogen with nuclear reactor then spraying them. If the engine malfunctions, it WILL spray radioactive parts down to earth, and nobody will like that.
