Global Insider: U.S.-South Korea Nuclear Agreement

With the U.S.-South Korea bilateral nuclear cooperation agreement set to expire in 2014, it will be difficult for the United States to refuse Seoul's push to renegotiate without damaging the broader U.S.-South Korean relationship.

Global Insider: U.S.-South Korea Nuclear AgreementSouth Korea and the United States recently began a review of their bilateral nuclear energy agreement that expires in 2014. In an e-mail interview, Mark Hibbs, senior associate in the Carnegie Endowment for International Peace's Nuclear Policy Program, discussed U.S.-South Korea civil-nuclear cooperation.

WPR: What is the status quo in terms of U.S.-South Korean nuclear cooperation?

Mark Hibbs: On the basis of a bilateral nuclear cooperation agreement from 1974, South Korea has built 14 of its 20 nuclear-power reactors with the help of U.S. industry and government agencies. The agreement permitted U.S. firms to supply technology, equipment and fuel for these plants, which were constructed by South Korean firms under license from U.S. companies, most importantly Westinghouse.

The bilateral agreement underpins ongoing U.S.-Korean nuclear commerce. It also permits South Korean labs and agencies to do nuclear research with U.S. counterparts. Some of this research in the nuclear fuel-cycle area has been interrupted by the United States on grounds that it is too sensitive.

WPR: What is driving the current South Korean effort to renegotiate the agreement, and what objections does the United States have?

Hibbs: South Korean firms intend to continue reactor-building with U.S. partners, both in Korea and abroad, but if the current agreement is not replaced with a new one in 2014, this cooperation would halt. But, as was previously the case for Japan, since South Korea's original nuclear cooperation agreement with the United States was concluded, Seoul has mastered nuclear-plant design, equipment manufacture, and construction, and wants this development reflected in new diplomatic and commercial arrangements.

Separately, South Korea wants the United States to allow it to extract and reuse uranium and plutonium from its spent nuclear fuel. Under the terms of the current agreement, the United States has stood in the way of this on longstanding nonproliferation-policy grounds and because the United States fears an escalation of tension with North Korea. In 1992, both Koreas agreed to refrain from reprocessing spent fuel or enriching uranium. Some South Koreans argue that this agreement was nullified when North Korea tested nuclear weapons and began enriching uranium. The United States disagrees.

WPR: What implications does this negotiation have for broader U.S.-South Korean relations?

Hibbs: South Korea is a firm U.S. ally. It will be very difficult for the United States to deny South Korea's bid for what it calls "peaceful nuclear sovereignty" without damaging the overall bilateral relationship and incurring South Korean resentment that Washington's ultimate trump card was its military and political leverage over the small country. South Korea argues that the United States has afforded more generous terms to the European Union and, especially, Japan.

Also, in 2008, South Korea and other nuclear-supplier states-party to the Nuclear Non-Proliferation Treaty accommodated a U.S. request and lifted nuclear trade sanctions against India, a country outside the NPT with nuclear weapons. This permitted a U.S.-India nuclear cooperation agreement, which allows India to reprocess its U.S.-origin spent fuel, to enter into force.

In 2004, it was revealed that South Korean scientists had engaged in experiments to enrich uranium that were not reported to the International Atomic Energy Agency. In 2008, the IAEA concluded that all nuclear activities in South Korea were for peaceful use. This appears to underscore South Korea's claims that it is an advanced, developed country and a responsible nuclear state with too much to lose in its relationships with others, including the United States, should it try to develop nuclear weapons.
