My apologies, I meant Daedalus. I can’t find any references to the Orion project you describe, though there have been several real spacecraft and related systems by that name.

You can start at Wikipedia:

https://en.wikipedia.org/wiki/Project_Orion_(nuclear_propuls...

Basically nothing of it was actually built (nuclear propulsion wasn't an well accepted idea - for good reasons that won't matter as soon as we start building in space). There was just some very small scale prototypes.

In comparison, project Daedalus moved much faster.

Those were launch systems or in-system vehicles though, and much cruder and less efficient than Daedalus which was optimised for interstellar travel.
