Some how this concept makes no sense to me considering that this reactor is small portable and designed to operate 15 to 30 years without refueling.
This long life core necessitates highly enriched Uranium or Plutonium fuel.
I checked out this analysis of the design and it shows that the core is between 78 and 83 percent enriched Uranium.
That means that this fuel is pretty close to bomb grade fuel. Some creative engineer could probably make it go boom. It would be dirty but what does a terrorist care.
You ship this to a third world country and it would be an open invitation to terrorist to high jack the reactor and put the fuel to their purpose; be it holding it hostage or breaking it open and making a bomb.
Nope. Not nearly enough enrichment for "boom-making". That was why I was wondering if it was a homogeneous reactor. With the lead coolant, the fuel would be intermixed with the lead (including radioactive lead isotopes from the fission process) and be virtually impossible to proliferate. Having separate fuel elements increases the likelihood of proliferation.
And that is still light years away from being a usable weapons charge... not only in material processing, but there are many other factors involved...
"Almost" pure pellets are completely useless in a bomb and it would take untold amounts of resources to convert them. Few nations have the money and expertise to do it, let alone an individual or small group.
