I know that nuclear fuel must be a precious resource, and to see that we wasted so much of it during those years is unsettling. We could have set that fuel aside to power civilization for centuries. Might we be able to recover any valuable radioactive material from the test sites? Since most of the warheads were detonated at just a few sites, there might be high concentrations.

The amount of fuel used by a warhead is tiny compared with a power station reactor. A typical nuclear warhead contains less than 50kg of fissible material. A typical reactor contains 50 tons or more.
