The photo @11:30 wasn't identified correctly. She's talking about spent fuel, high-level waste ("very big problem"), but the photo slide is absolutely not that at all; it is stored depleted uranium hexafluoride, a byproduct of isotope enrichment. (The site is the USEC gaseous diffusion plant in Paducah, Kentucky, USA). Comparatively benign chemical waste.

(Maybe I misunderstood, but the talk seemed to imply that spent fuel storage was being shown. It wasn't.)
