North Korea claims it has denotated a H-bomb

North Korea has claimed it made a successful hydrogen bomb test.

Last month, North Korean leader Kim Jong-un said Pyongyang had developed a hydrogen bomb, although international experts were sceptical.

Hi Mark,

Happy New Year!

To be historically accurate, only by 64 years.

The first thermonuclear detonation was the "Ivy Mike" shot in 1952.

The Koreans are claiming they have now detonated a full thermonuclear
H-bomb, not simply an A-bomb.

Worryingly, the North Koreans have been working on and testing the missile delivery systems as well.

[Atmos (Colin)]

Should be very easy to confirm or deny, there are enough neutrino detectors scattered around the world so there would have been a lot of hits at the same time, shortly before a registerable tremor.

[Sconesbie (Scott)]

Not sure I'd believe what N Korea says. Reports also say there was an earthquake rated 5 or so near the reported detonation site. Propoganda?? Let's see what others removed from the area say. We need some experts there. If it is true however, it is worrying.

Whilst the world awaits news from the monitoring stations of the IAEA
whether North Korea's claims are true or not, one possibility occurred to
me that the North Korean detonation way be what is referred to as
a "boosted" fission device.

Using tritium and deuterium gasses inside a fission device, one can boost
its performance through the release of fast neutrons. Much of the plutonium
or uranium in a nuclear weapon can fail to fission before the device blows
itself apart and boosting can achieve a higher yield. Some of the tritium
and deuterium mixture can undergo fusion and these devices were sometimes
referred to as fission-fusion-fission weapons.

This can also result in a smaller device that is much easier to weaponize
and deliver.

The energy released by the fusion stage of such devices was relatively
negligible. It's job was to aid in the fission efficiency.

The US underwent a brief period where they developed and tested them
before they went on to build the first full-scale H-bombs. Boosting is
also employed in full-scale staged thermo-nuclear weapons.

If they are playing with using other elements to assist in the process, lets just hope they dont make the same mistakes the yanks made when playing with Castle Bravo :-(

Hi Andrew,

Indeed.

Imagine some alternate universe where skimpy swimwear was referred
to as a pyongyang rather than a bikini. Doesn't have quite the same
ring about it.

Since the Ivy Mike and Castle Bravo fusion tests were so technically challenging
and expensive to design at the time, it makes the North Korean claim extraordinary.

The worry if it is true is the prospect of further proliferation.

The North Koreans purchased much of their nuclear weapon
design knowledge from the Pakistanis as a result of the infamous
Abdul Qadeer Khan connection.

BBC documentary on Abdul Qadeer Khan here -

For a country that is undergoing a trade embargo, there must be a serious
motivation for North Korea to bring in hard currency through the sale of whatever
new nuclear weapons technology they may have independently developed.

Unless the dear leader has read Sun Tzu, and successfully employed the use of spies to get a head start.
The Russians saved quite a bit of time and money using this method via the Rosenbergs and Fuchs etc. Quite a cheap program really.
Also, and more scarily, is someone else still covertly helping, to enable testing of "their" new ideas without getting blamed????

Assuming the magnitude 5.1 earthquake was caused by the test, it is reasonably easy to convert to the yield in kilotons of TNT- in this case about 7.26, which is quite a small device. It's smaller than the trinity test by a good margin. Considering that the yield of an H-bomb is usually in the tens of mega tons equivalent, it's likely that they finally managed to get one of their plutonium devices to work properly.
Irrespective - one of these in the hands of a lunatic is very disturbing.

Mr Kim feeding his prisoners a bit of BS on the back of an earthquake so when he rails against America, his people believe the mighty Democratic Peoples Republic of North Korean Army can destroy the baby eating Americans any time Kim gives the go ahead.
It's bloody sad, and if China didn't back them this country would have been unified decades ago under a democratic system of government.

He is a strange man, and i don't believe any of the crap that they report, other than the cruel and disgusting person that he is, and how they treat their own citizens, the sooner he is gone the better.

Truth is this cant in anyway be ignored.

Not just this Korea, few of of nations already have this weapon for some time, this guys just said they had it now.

Future is going to be more more diplomatic else some ones "one stupid" move 'Énd of the days'

So live happily all the current days we got with family.... good days

Guess i will spend more time star gazing now.

I don't think it was a full H bomb -

North Korea may have just been testing to see if they could get a small
amount of deuterium & tritium to achieve fusion.

[Regulus (Trevor)]

These three points;

• China is p***ed with them for not giving a heads up to their allies and financiers.
• The earthquake was detected 10klms below ground.
• A hydrogen bomb requires and atom bomb as a detonator, and we all saw how their atom bomb fizzled. And i'm no expert, but i don't think you can have a thermo-nuclear bomb give such a small yield (correct me if I'm wrong)

He took credit for an earthquake because he is a truly screwed up human. It is enough to know that he was schooled and holidayed in Europe and knows that Americans don't eat children, and that the rest of the world isn't suffering under terrible political regimes. Yet he went back and continued the lies about the rest of the world to his people when he became their god. Sociopath. Whether in actuality, or just acting the part, the result is the same.
A hot lead injection to his brain would be a great kindness to the Nth Korean people.

Data seems to contradict your proposed depth.

I'm basing on initial newspaper reports. Haven't looked further.
Thanks.
