Kim dodges sanctions to gain nuclear weapons tool

North Korea

North Korea obtained a key tool used in the production of nuclear warheads by shipping it through three separate countries in an elaborate ploy to dodge international sanctions on its weapons programme.

According to a US think tank, the authorities in Mexico, South Africa and China failed to spot false documentation for a vacuum furnace, which can be used in creating fuel for nuclear warheads. The case demonstrates the increasing difficulties of enforcing international sanctions against North Korea.

The report by the Institute for Science and International Security cites unnamed government sources to describe an incident in 2022, when the vacuum furnace was shipped from Spain with an accurate description of its function.

Such equipment is designated "dual use" under UN sanctions, meaning that while it has legitimate civilian uses, it also has an important function in Kim Jong-un's nuclear weapons program and is banned for export to North Korea.

"This type of furnace is a mainstay of a nuclear-weapons program, particularly one that uses weapon-grade uranium as the nuclear explosive material, as North Korea is known to do," David Albright, a physicist and former weapons inspector, said in the report. "With North Korea expanding its uranium-enrichment program and producing greater quantities of weapon-grade uranium, this new furnace would be especially important."

The shipment arrived in Mexico, where it was given a new code under the "harmonised system" used internationally to label traded items. Listed under the general term "machinery", it was then shipped to South Africa where it was redesignated as scrap metal and sent to China, from where it passed to North Korea.

Although Beijing agreed to sanctions against North Korea passed by the UN security council, it has become lenient about enforcing them as relations with the West have deteriorated.

The think tank called for "additional scrutiny" for such exports to China.

The report comes as the governments of the US, Japan and South Korea said North Korean hackers had stolen more than $600 million in cryptocurrency in 2023, which could fund its nuclear programme.

In a joint statement last week, the countries said that Pyongyang's cyber programmes posed a threat "to the international community" and "the intergrity and stability of the international financial system".

They added: "The three governments are working together to prevent North Korea's theft of private sector and others and to recover the stolen funds, with the ultimate goal of blocking the illicit proceeds used for North Korea's illicit WMD [weapons of mass destruction] and ballistic-missile programmes."

The governments also warned of the threat of North Korean IT workers impersonating Japanese citizens to get remote work in overseas companies, with their income channelled to the regime. In 2023, the UN estimated as many as 10,000 North Korean IT experts worked overseas.

The article is from the right-wing Heritage Foundation so that doesn't surprise me however if Putin decides Russia needs to perform a new round of nuclear tests (And does so) it's a sure bet that Trump will order the DOE to reactivate the NPG for some new US nuclear tests.

Stupid idea, we have tons of data from past tests and have developed technology to no longer need them. All this will do is allow China and Russia who don't have those means to do desperately needed testing.

Every time you make a new computer model, you need to do a test shot to validate it.

What you're saying is that the computer models we have are 30+ years old and therefore SUCK.
 
There are other ways to get that data to validate models without having to do a full scale shot. I've seen it.

Not to mention that the sensors used to take measurements from the exploding test-device (In the brief time they exist before being vaporised) while state-of-the-art at the time are now 32 years old, there has been enormous advances in high-speed sensor tech in those 32 years since the last test-shots in 1992.
 
On the other hand, the U.S. is not designing new warheads. New weapons are just rebuilds of existing physics packages.
 
Missions and associated yield / effect requirements are mushrooming again for one thing. Warheads in the 300kt range just don't cut it any more for strategic targets (if they ever really did).

Could you give an example of a target where 300kt with a <100m CEP would not suffice?
 
ROK and Japan are not adopting nuclear weapons anytime soon for domestic political reasons. I am all for it, but it would be an economic nightmare immediately.
 
Do they already have weapons-grade fissile materials on hand?

Japan has a massive stock of Pu and recently built a reprocessing plant for it. They would be awash in weapons grade plutonium if they lifted their finger. ROK much less so I think; I’m unfamiliar with their efforts. But as Bestest Korea has shown, even a half dozen weapons would carry a lot of weight.

If that reprocessing plant also includes AVLIS or MLIS equipment then Japan can in principal create 100% Pu-239, 100% Pu-238 could be made for use by JAXA in RTGs (For probes to the outer planets) and the rest of the Plutonium isotopes used as reactor fuel.

On another note it would be interesting to see if Japan will stockpile weapons-grade Li6D.
 
I haven’t studied their efforts, but they have a huge decades old civilian nuclear program that results in a huge stockpile of plutonium waste that is just raw material for purification. They also have an existing civilian solid fueled three stage orbital rocket that is basically MX by another name. They can create an ICBM in months.
 
It depends on what isotopes of Pu it is, not all Pu is usable for weapons.

Most of the Plutonium formed is Pu-239, there are a number of techniques that can be used to isotopically purify the Plutonium to get the Pu-239, the latest and best methods use AVLIS or MLIS (URLs are in post#4,590).

Edit: I forget about a relatively new but still largely classified enrichment process developed in Australia called SILEX.

Yes they could reprocess the Pu, but they would first have to build the facilities to do so. All their civilian reactors are LWR which produce significant (~50%) amounts of Pu-240 while you need to get down to <7% Pu-240 for weapons-grade Pu. They may have a lot of Pu lying around, but its not usable as is.

These are very good points but now that Tubby has operational nuclear weapons and missiles that can reach the CONUS I won't be surprised at all if the Japanese government is quietly making plans and secretly allocating the needed funding to build the required Pu-239 purification facilities.

That plant is specifically to reprocess waste into reactor-grade Pu, which is a very different process from turning waste into weapons-grade Pu.

I admit my ignorance on that matter. Is it a different isotope or is the plant simply unable to enrich to the proper levels, or some other issue? I had been led to believe that the capacity for nuclear weapons production was specifically why some people protested the plant.

If you're simply talking about separating out the Plutonium from the Uranium (The PUREX process) and of course the fission products are separated out (There are a number of useful radio-isotopes here such as Cobalt-60, Strontium-90 and Caesium-137) which is a chemical process.

On the other hand separating out Plutonium isotopes uses some form of isotopic separation of which there are a number of methods that could be used. IMO once the Plutonium has been extracted from the spent fuel-rods then it needs to go through two series of isotopic separation with the first series to isolate the Pu-239 from the Pu-240, 241 and 242 then seperate the Pu-238 from the Pu-239. With the result you have three product streams:

Stream 1: Pu-239 for weapons use
Stream 2: Pu-238 for use in powering RTGs (JAXA would have use for this)
Stream 3: Pu-240, Pu-241, Pu-242 and Pu-243 which could be used as reactor-fuel.

I had been led to believe that the capacity for nuclear weapons production was specifically why some people protested the plant.

The only thing they're parading is their wilful ignorance.
