A half hour north of Seattle in Everett about 15 black barrels sit in a nondescript storage facility owned by the nuclear innovation company TerraPower. Each barrel is the size of a large trash can, around 110 L, and weighs over 350 kg. What’s held inside is . . . complicated. Just inside the thick shell is a layer of foam padding. Within that sits a heavy-duty container, which in turn encloses a steel pipe capped on each end. Inside the pipe is a screw-top aluminum can, which holds a thick plastic bag, which encases a glass vial about the size of a tube of toothpaste.
