GainRainSo, is it "on" or "under"?
Perhaps you're thinking of expressions like, "The submarine got there under its own power."

I think "under" might be used when there are options.
When we ran out of gas, we completed the voyage under wind power. ("On" would also work here.)

Thank you for your answers Avangi and Mr Micawber.

So, "on" and "under" and they are interchangeable.

I wouldn't say so.

In your original examples, "This submarine runs on atomic power" would be the only choice.

I think "on" is always correct, and "under" is acceptable in limited circumstances.
