“The uranium composition, as far as the actual irradiated meat, ends up being about 95% of the material, and then the other five percent are these fission products that grow in over the course of the irradiation, as well as the, what I call the transmutation products”

“I don't think about it as nuclear waste, I think about it as use nuclear fuel, because there's actually a lot of energy value with respect to that”
Shafer: TRISO fuel resists leaching, whereas molten salts require waste conditioning
“Triso, again, is a wonderful waste form for all the reasons that people love it as a fuel form, right? The radioactive material is not getting out when it's reacting in the reactor, and it's not getting out when it's Sitting on the side of the building. Howeve…”
Shafer: States will successfully block nuclear waste transit if they oppose it
“If a state does not want you to move nuclear material through the state, it will find a way for you to not move nuclear material through the state”
