Over the last forty years, South Korea (or the Republic of Korea, or ROK) and the United States have become essential partners on nuclear matters. The United States provided the technology and knowhow necessary for Korea to establish a nuclear sector. Koreans mastered that technology and have worked to improve on it, with the twin goals of expanding their country’s energy independence and becoming a leading exporter of nuclear power production facilities. The two states’ nuclear energy industries have become intertwined. They cooperate on multiple initiatives to strengthen international nuclear security and nonproliferation measures. Collaborative research ties amongst nuclear scientists from both countries run deep. Arguably, each state is the other’s most important nuclear partner.
As with all maturing relationships, there remain differences of view and priority that must be managed. Though unlikely, a disruption in ROK-US nuclear relations would have wide-ranging, deleterious effects on both states. For this reason, the conclusion in June 2015 of a new bilateral treaty, the Agreement for Cooperation Between the Government of the United States of America and the Government of the Republic of Korea Concerning Peaceful Uses of Nuclear Energy (hereafter referred to as the 123 agreement after section 123 of the Atomic Energy Act, the relevant US statute) is a critical milestone. The new agreement establishes the terms for nuclear cooperation for the next twenty years. It is expansive and forward-looking, providing the basis for unusually broad and deep nuclear ties. The 123 agreement will bring predictability to the relationship at a time when the global nuclear energy outlook remains in flux.However, the new nuclear agreement only managed to partially resolve several deep-seated differences between the two sides that were illustrated by the fact that negotiations on a new agreement lasted more than four years and required an extension to complete. The agreement creates a new political framework for managing divergent views over how to cooperate most effectively, but differences may yet re-emerge and frustrate cooperation. The challenge before the two governments now is to implement the new agreement in ways that can either resolve or remove these differences and solidify existing ties. In other words, the two countries should seek to build a nuclear partnership in deed, not just in word.
This report articulates a vision for ROK-US nuclear partnership for the next two decades, a period which aligns with the duration of the new agreement for cooperation. It highlights challenges and opportunities and provides recommendations intended to deepen and expand the range of existing cooperation in ways that will support a stable and sustainable nuclear partnership. The objective of the report is to describe a desirable and stable end-state for the relationship—an enduring partnership—and to identify steps along the path to achieve it. It discusses multiple areas of cooperation, assesses strengths and weaknesses of existing ties, and identifies practical activities both parties can pursue toward building the partnership....
