Good question, and believe it or not there have been small reactor concepts that failed for not considering that exact point.
Ours is designed to live in essentially a spent fuel cask. These things have been designed and tested to withstand being dropped from a thousand feet, being hit by missiles or airplanes. Seriously check out youtube there are crazy videos like this: https://www.youtube.com/watch?v=jBp1FNceTTA
So from the time the reactor leaves our factory, to when it's put underground, till a decade later when it's taken out and shipped back for refueling, the fuel is locked in the reactor which is locked in this uber robust "cask".
This design is a fast reactor which means it can recycle fuel. So beyond its first decade installation we can recycle the fuel approximately 6 cycles before there is any amount of leftover that must be removed. That would be about 70 years, and the volume would be about the size of a basketball (fully glassified) and the lifetime would be on the order of a hundred years. That could be stored at our central facility or another facility, as it would not be weaponizable.
