North Korean Bomb was Dud

CNN confirms that the North Korean nuclear bomb test was a failure.  According to government sources, the design goal was 4 kT, but the actual yield was less than 0.5kT.  If this is a plutonium bomb as reported, then I would speculate the problem was an excess of isotope P240 (which causes pre-detonation and a marginal yield).  See this Wiki article for more details on that.

This probably explains why little or no radioactive emissions have been detected (the energetics of a full-throttled nuclear explosion makes the complete containment of radioactive gases highly problematic!)

I’ll also point out that building a weapon that can be detonated in a tunnel is a much easier job than building one that is payload compatible for an intercontinental missile.  This is good news to counter reports that North Korea may have enough fissile material for ten bombs.

Maybe we’ll get lucky and they use up their reserves trying to make a bomb that works.  Really, haven’t they learned anything from the United States?  They should outsource for the nuclear technology, just like Iran did.

Update: Thanks to Rob for pointing out my typo! I can now say with confidence that the problem of transvestite nuclear bombs in the North Korean Navy is relatively under control.

Transvestite bombs...what will they think of next?

You should have an edit button next to the title of the post if you want to fix that.

I stand by my call. I don’t believe they attempted an actual nuclear weapon detonation. I think this is Jong Il stamping his expensivly shod little feet and screaming for attention. And it is working. I figure DRPK for building and selling sizeable dirtybomb devices, not actual fission or fusion bombs. And they damn sure ain’t gonna build anything that will fit on a missle. You have to wonder just how dedicated the people working on his programs are.

2H9, then there is this possibility:

“It is possible with a relatively small underground blast that there would be no significant release of radiation,” said Hideshi Takesada, of the National Institute for Defense Studies, a branch of Japan’s Defense Agency

I would like to think that North Korea used up 6+ kg of their ~ 20 kg of plutonium.  Let’s hope for two more failed tests, followed by… silence.

We can only hope. It is just that the whole thing does not feel right. Saw an article in Daily Yomiuri that put forward the same scenerio, possibly based on the NIDS piece. Though that reporter seemed unconvinced. I’ll go see if I can pull it from their archives, not sure if they keep translated articles beyond 24 hours. A point I have been trying to find out about is the EMP signature. We have at least one satelite giving North Korea the hairy eyeball all the time, and they pick up the electrical emissions signature from equipment,comunications, and computers. Wouldn’t EMP from even a small release show up like a flash bulb?

Typically you only see a significant EMP, when the detonation occurs in the ionosphere… it is the result of the rapid acceleration of charged particles that causes the EMP radiation.  For a “normal” bomb, you only get this when you are exploding the bomb in a plasma (that is the media is already charged).  The US military has “E” bombs that it is rumored get around this.

Short answer, I don’t think you would have seen much, unless you had a gamma-ray telescope focused on the mountain at the time.
