Is nuclear energy a sustainable source of energy?

I have seen many people on Reddit advocating the use of nuclear energy, and since I don't know much about the subject I decided to research it. However, I have found many conflicting stances on the use of nuclear energy, more specifically on whether nuclear energy can be sustainable. I appreciate any clarification on the topic.

I think that it's technically a non-renewable resource-we are using nuclear fuels more quickly than they are being created. However, the amount of usable nuclear fuel eclipses the amount of available fossil fuel and thus it's considerably more sustainable than every other non-renewable resource. There are certain types of uranium in particular (238 IIRC) that would take us an incredibly long time to run out.
