Will there be any waste that must be stored for 50000 years? What are the characteristics of the waste?

I have to reply in qualitative terms since I don't have good numbers at hand. A fast reactor is about 100 times better than the thermal reactors many of us are familiar with. It can use the "waste" from a thermal reactor as fuel, thus using for energy the long-lived and highly radioactive transuranic elements. It has about 100 times less volume of waste that is highly radioactive for hugely less time. It can use as fuel the depleted uranium (U-238) that remains from making the enriched uranium needed for weapons--we have stockpiled tons of it. It does NOT use pressurized water for cooling.
