Abstract:
In tracking trade data and trade flows, Harmonized System (HS) codes are routinely used to aid searches for dual-use commodities and to help guide the identification of dual-use items that require a license or greater scrutiny. A recurring concern is shipper falsification of HS codes to evade detection or payment of duties. An illustration of such falsifications is a case we learned about via government sources from around 2022 that involved North Korea and a dual-use vacuum furnace suitable for uranium melting that wound its way from Spain to North Korea, via Mexico, South Africa, and China. Such a furnace is typically controlled under the Nuclear Supplier Group (NSG) Part 2 list and is banned for export to North Korea under United Security Council resolutions. 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. With North Korea expanding its uranium enrichment program and producing greater quantities of weapon-grade uranium, this new furnace would be especially important.

Abstract:
Several years ago, the Institute reported about the relatively large, multinational Chinese company Shenyang Machine Tools Company supplying sophisticated computer numerically controlled (CNC) machine tools, equipped with Western controlled software, to North Korea in violation of UN Security Council (UNSC) sanctions and a supplier country’s trade control laws that banned re-export of this software. New information details the disingenuous way in which the Chinese government investigated this case, indicating nonetheless inadvertently that North Korea received these machine tools, while also demonstrating China’s utter disregard for enforcing UNSC sanctions or its own or others’ export control laws. This case serves as another of the many cases highlighting China as a long-time irresponsible trading partner that responsible companies should avoid when sensitive dual-use goods are involved, lest they be complicit in outfitting North Korea’s, Iran’s, or Russia’s military programs. Today, responsible suppliers are inadvertently facilitating Russia’s prosecution of an illegal war against Ukraine. Given Shenyang Machine Tools Company’s recent exports of goods to Russia with Harmonized Shipments (HS) codes found on the Bureau of Industry and Security (BIS) Common High Priority List (CHPL), this company should be considered for sanctions.

Abstract:
The Trump administration has announced that it has created a new North Korea policy that is aimed at exerting maximal pressure on Pyongyang but also achieving negotiations to denuclearize North Korea. However, denuclearization negotiations do not appear imminent. The Trump administration has stated that now is the time for focusing on creating greater pressure on North Korea, and North Korea has signaled little interest in negotiations and much more interest in developing and keeping its nuclear weapons, comprised of both the warheads and missiles. But it is not too early to discuss what negotiations should look like. Many have stated that the denuclearization process should start with the creation of a freeze of North Korea’s nuclear program, as was done in previous North Korean negotiations. A freeze, albeit limited, was also the starting point for the negotiation of the Joint Comprehensive Plan of Action (JCPOA), or Iran nuclear deal. But what should this freeze look like in new North Korean negotiations, given all its nuclear advances in the last several years?

5. Future Directions in the DPRK’S Nuclear Weapons Program: Three Scenarios for 2020

Abstract:
Like many secret nuclear weapons programs, the DPRK goes to great lengths to hide its capabilities to produce nuclear explosive materials and nuclear weapons. Despite these actions, a picture can be drawn of North Korea’s current and projected plutonium and weapons-grade uranium (WGU) stocks. Knowing these plutonium and WGU stocks can, in turn, allow an estimate of the DPRK’s current number of nuclear weapons and a range of projections of the number North Korea could build in the next several years. Although great uncertainty surrounds these projections, as well as the quality of North Korea’s nuclear weapons, these projections form a reasonable picture of the DPRK’s possible nuclear weapons futures, absent actions to significantly limit its nuclear programs. After summarizing estimates of stocks of separated plutonium and weapons-grade uranium as of the end of 2014, this report develops three projections of future nuclear arsenals through 2020: low-end, medium, and high-end nuclear futures. In developing these projections, which are intended to bound North Korea’s nuclear futures, a number of constraints are considered, including the number and size of nuclear production facilities, future underground testing, the extent and success of nuclear weaponization efforts, costs, and access to necessary goods and classified and proprietary technologies abroad.

Abstract:
For years, great controversy has surrounded North Korea’s uranium enrichment program (UEP). How large is it? Has it made weapon-grade uranium (WGU)? How much could it make in the future? But there are also broader questions. What is the role of the UEP in the larger North Korean nuclear program? Is the UEP program strictly oriented to make 3.5 percent low enriched uranium for a civilian light water reactor (LWR) under construction at the Yongbyon nuclear complex, as North Korea says? Is it to make WGU? Or could North Korea intend to further enrich uranium for use in the light water reactor to make plutonium for nuclear weapons? Although LWRs are not typically used to make weapon-grade plutonium, they can do so efficiently if the reactor core is specially designed. Finally, how should the United States respond to the UEP and the associated uncertainties in this program? This ISIS report attempts to answer these questions utilizing plausible scenarios about past and possible future operation of the centrifuge program that could result in the production of WGU and future operation of the LWR that could make weapon-grade plutonium. In doing so, the report seeks to organize the incomplete data and derive answers to the above questions that have policy relevance. The report’s results are necessarily preliminary because significant uncertainties exist about the number of North Korean gas centrifuge plants, their operation, and the amount and enrichment level of the enriched uranium produced in them. In addition, although North Korea has said that its Yongbyon LWR is for civilian purposes, this statement is unverified and doubts about its potential use are justified. This report is designed to be updated if and when additional information is obtained.

This report is designed to be updated if and when additional information is obtained. This report presents and evaluates a wide range of information about North Korea’s plutonium and uranium enrichment programs. It identifies gaps in knowledge of these programs. For this report, ISIS developed a variety of estimates of North Korea’s current and future stocks of WGU and weapon-grade plutonium. Although the numerical possibilities are broad, most of the discussion focuses on the central estimates. These results are presented in terms of kilograms of these materials. This report, and in particular this summary, uses the convention of converting these numbers into nuclear weapon equivalents. Often the term “equivalents” is dropped. Such a conversion is necessary when both plutonium and WGU estimates are discussed, since it allows for a more meaningful discussion of the aggregate amount of both fissile materials.

8. North Korea’s Plutonium Declaration: A Starting Point for an Initial Verification Process

Author:

Special Report
Institution:

Abstract:
On December 27, Japan’s Tokyo Shimbun newspaper quoted U.S. and North Korean officials saying that North Korea had declared a plutonium stockpile of about 30 kilograms. The report was subsequently picked up by several wires, including AFP and UPI. Based on discussions with a knowledgeable official, this roughly 30 kilograms of plutonium apparently refers to a stock of plutonium that North Korea separated from irradiated fuel produced in the five megawatt-electric reactor at Yongbyon. The separation of the plutonium occurred at the Radiochemical Laboroatory at Yongbyon. If this quantity refers to separated plutonium (and not the total quantity of plutonium produced in the spent fuel of several reactor cores), it does fall inside the lower bound of the range of the amount of separated plutonium that ISIS has assessed North Korea could now possess.

Institute for Science and International Security
Abstract:
The October 3, 2007 Six-Party Talks accord outlines a roadmap for the disablement of the Democratic People’s Republic of Korea’s (DPRK) core nuclear facilities. While an agreement on “Second-Phase Actions for the Implementation of the Joint Statement” has been secured, the specific details of the nuclear disablement process are still being developed. The primary goals of this Working Paper are twofold. First, to establish a definition for the term “disablement” which has only recently achieved widespread usage in the disarmament and nonproliferation community. Second, to outline the types of steps that will or could be taken at key facilities in the DPRK to achieve various disablement objectives. This Working Paper was commissioned by the Korea Working Group (KWG) at the U.S. Institute of Peace. The KWG brings together the leading North Korea watchers from the government and think tank communities to discuss pressing policy issues in the political, security, social, and economic fields.
