You have to plan for it, but you're not going to have any waste until the first refueling, which is ~ 18-24 months after you start operations. (unless SMR have a drastically different fuel cycle than the big ones, I honestly don't know)
Ha, while discussing this with you, S3 just released their video with Radiant, an SMR startup.

The only thing that I've seen on the topic is this:
> Results reveal that water-, molten salt–, and sodium-cooled SMR designs will increase the volume of nuclear waste in need of management and disposal by factors of 2 to 30.
> ... In addition, SMR spent fuel will contain relatively high concentrations of fissile nuclides, which will demand novel approaches to evaluating criticality during storage and disposal.
