I can add to that question, as well.
The process has been under way for decades in France. France reprocesses nuclear fuel, and they've been doing it for other countries successfully for many decades: Germany, Japan and the U.K. Quite frankly, that fuel has been reused over and over again. What it produces, effectively.... What you would get in terms of waste, if you use nuclear energy for your entire lifeline, would be a footprint about the size of a pop can. The residual left over is vitrified into glass logs. The studies I'm familiar with show that those glass logs last for a minimum of 10,000 years, with the possibility of 100,000 years. The only reason they don't go to 100,000 years is that they don't really have the empirical data to prove it, so they stop at a much shorter time frame. Those logs are vitrified and pretty much impermeable, so the waste is contained and stored.
Thank you.
