So?
Without a warhead the missile is useless, or did you not understand that?
Let us review, so that there no more misunderstandings.
There are several different ways to know how long North Korea ran their reactors, so we know how much Pu-239 they
could have produced.
Best estimate is 60 kg, but that's what was produced in theory,
not what was separated.
Nothing in this Universe is 100% efficient.
But, I'm going to give you the benefit of the doubt and assume they extracted all 60 kg.
North Korea had a low yield fission test shot. That required 4.5-4.6 kg, and with tailings about 5 kg.
That leaves them with 55 kg.
A second test appears to be a test of a fission trigger device. It was estimated at 6-8 kt. Normally, you use an 8 kt fission trigger for a fission-fusion device in the 400 kg to 450 kt range. That would have taken 12-13 kg of Plutonium and with tailings about 15 kg.
Now they have 40 kg.
A third test shot was reportedly fission-fusion, and it appears they used a 8 kt fission trigger to fuse a limited amount of Lithium or Deuterium.
That leaves them with 25 kg.
You could make a fission warhead with 25 kg. It'd be about 60 kt.
Or, they could make 3 fission triggers.
For a 750 kt warhead, you use a 12 kt fission trigger; 15 kt for 900 kt to 1.1 mt and for anything over that, you need a 20 kt fission trigger.
I mention that because the Federation of Ass-Clown Scientists always lie.
When you calculate fallout from a 750 kt warhead, it is 12 kt and not 750 kt.
Why? Because you get 12 kt from fission, and 738 kt from fusion....yeah, Helium, which is not radioactive and which falls
up, not out.
Right? Because Helium is lighter than air? Right? That's what makes balloons go at your kid's party.
It's been claimed North Korea has been running their reactors, but no evidence thus far to support that.
