Abstract:
On May 28, 2018, the New York Times reported on a technical roadmap for North Korean denuclearization written by Stanford University professor and scientist Siegfried S. Hecker and colleagues Robert L. Carlin and Elliot A. Serbin. While we greatly respect the work of Dr. Hecker and colleagues, we disagree on the up to 15-year timeline put forth for completing full denuclearization. Our assessments are based on verified dismantlement in other countries. If North Korea agrees to denuclearize and to cooperate fully, admittedly big “ifs,” then verified dismantlement of the key parts of its nuclear weapons program can happen in parallel and be accomplished in as little as about two years. Gaining assurance that North Korea is not hiding relatively small but significant amounts of plutonium, enriched uranium, or nuclear weapons will take longer than two years and will likely fall to the International Atomic Energy Agency (IAEA) to handle as part of bringing North Korea into compliance with the Nuclear Non-Proliferation Treaty as a non-nuclear weapons state. This whole process could take several more years, as the IAEA insists on accounting for even grams of nuclear explosive materials, as it should. Decommissioning operating reactors and plutonium separation plants will also take years longer. But within a few years, all the declared nuclear weapons and stocks of plutonium and enriched uranium could be verifiably eliminated, and all key facilities identified and rendered unable to operate. Moreover, the verification process can include a sufficient estimate of the amount of plutonium and enriched uranium North Korea has produced, allowing a first order check on whether North Korea has declared all its nuclear weapons. Of course, this process could take longer, but such a process should not be structured in a way that invites North Korea to go slowly and delays the date when North Korea demonstrates it intends to get rid of its nuclear weapons. The past two major negotiations with North Korea are a cautionary tale for avoiding a drawn-out process, where the most difficult decisions are left to the future.

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?

3. 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.

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

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.

Working Paper
Institution:
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.

Abstract:
Verified dismantlement of the nuclear weapons program of the Democratic People’s Republic of Korea (DPRK) can be accomplished successfully. Although difficulties abound in reaching an agreement with the DPRK to achieve this goal, the methods and steps involved in the dismantlement process are well understood. Because this goal remains vital to U.S. and international security, the United States has joined with China, Japan, Russia, and South Korea in working toward verified denuclearization of the Korean peninsula with the cooperation of the DPRK. These six nations have launched a series of negotiations, called the Six-Party Talks, aimed at resolving the crisis over the DPRK’s nuclear program. These nations are also attempting to create a plan to dismantle the DPRK’s program in a manner with which all the nations can feel secure.
