In August 2004, South Korea revealed the extent of its highly secretive and sensitive nuclear research programs to the IAEA, including some experiments which were conducted without the obligatory reporting to the International Atomic Energy Agency (IAEA) called for by South Korea's safeguards agreement. The failure to report was reported by the IAEA Secretariat to the IAEA Board of Governors; however, the IAEA Board of Governors decided to not make a formal finding of noncompliance. South Korea is one of the few countries that has the raw materials and equipment to produce a nuclear weapon but has not.^{[citation needed]} If the South created nuclear weapons it could change the balance of power on the Korean peninsula. The United States has constantly reassured the Republic of Korea that their own nuclear arsenal will suffice in times of danger against North Korea, but recent studies show that over two thirds of South Koreans prefer nuclear weapons to be in their own control, which in time might become a possibility, especially due to the balance of military power changing from the U.S to the ROK in 2015.

Early Nuclear Ambitions

When the United States notified its plan to withdraw USFK in 1970 July, South Korea first considered the possibility of an independent nuclear program. Under the direction of South Korea's Weapons Exploitation Committee, the country attempted to obtain plutonium reprocessing facilities following the pullout of the 26,000 American soldiers of the 7th Infantry Division in 1971. After South Vietnam had fallen in April 1975, then South Korean president, Jung-hee Park first mentioned about its nuclear weapons aspiration during the press conference on 12 June 1975. However, under pressure from the United States, France eventually decided not to deliver a reprocessing facility to South Korea in 1975. South Korea's nuclear weapons research program effectively ended on April 23, 1975 with its ratification of the Nuclear Non-Proliferation Treaty.

Post-NPT Programs

The South Korean government insists that its nuclear program is for peaceful purposes only.

Previously unreported experiments

In 1982, scientists at the Korean Atomic Energy Research Institute performed an experiment in which they extracted several milligrams of plutonium. Although plutonium has uses other than the manufacture of weapons, the United States later insisted that South Korea not attempt to reprocess plutonium in any way. In exchange, the US agreed to transfer reactor technology and give financial assistance to South Korea's nuclear energy program. It was revealed in 2004 that some South Korean scientists continued some studies; for example, in 1983 and 1984 Korea Atomic Energy Research Institute was conducting chemical experiments related to the handling of spent fuel that crossed the reprocessing boundary.

Later, in an experiment at the same facility in 2000, scientists enriched 200 milligrams of uranium to near-weapons grade (up to 77 percent) using laser enrichment. The South Korean government claimed that this research was conducted without its knowledge. While uranium enriched to 77 percent is usually not considered weapons-grade, it could theoretically be used to construct a nuclear weapon. HEU with a purity of 20% or more is usable in a weapon, but this route is less desirable because far more material is required to obtain critical mass; thus, the Koreans would have needed to produce much more material to construct a nuclear weapon. This event and the earlier extraction of plutonium went unreported to the IAEA until late 2004.

IAEA Response

Following Seoul's disclosure of the above incidents, the IAEA launched a full investigation into South Korea's nuclear activities. In a report issued on November 11, 2004, the IAEA described the South Korean government's failure to report its nuclear activities a matter of 'serious concern', but accepted that these experiments never produced more than very small amounts of weaponizeable fissile material. The Board of Governors decided to not make a formal finding of noncompliance, and the matter was not referred to the Security Council.

Pierre Goldschmidt, former head of the department of safeguards at the IAEA, has called on the Board of Governors to adopt generic resolutions which would apply to all states in such circumstances and has argued "political considerations played a dominant role in the board’s decision" to not make a formal finding of non-compliance.

American nuclear weapons in South Korea

In 2013, South Korean Prime Minister Chung Hong-won rejected calls to again station American tactical nuclear weapons in South Korea.

Nuclear Capable state

Although currently South Korea is under the US nuclear umbrella of protection, it could very well break away and try to develop its own nuclear weapons if necessary. Like Japan, South Korea has the raw materials and resources to create nuclear weapons. Although many analysts have not taken a careful and extensive look at previous South Korean experiments,^{[citation needed]} previous incidents show the Republic of Korea (ROK) to be able to possess nuclear weapons in anywhere from one to three years if necessary. The ROK has been shown before to create enriched uranium up to 77%, which although not particularly powerful, shows that South Korea has the potential to make nuclear weapons with higher enriched uranium. South Korea does not have any ICBMs but possesses a wide range of SRBM and MRBMs through the Hyunmoo series of ballistic missiles currently fielded to the ROK Army. The Hyunmoo series of ballistic missiles works similarly to the American Tomahawk Missile, which can be armed with the W80 and W84 nuclear warheads. Theoretically, if needed, the 500 kg conventional warhead could be replaced by a small nuclear warhead. The Hyunmoo missiles can already cover the entire range of North Korea and would drastically change the North's disposition if the South had nuclear armed MRBMs. Even though the ROK could procure nukes, currently like Japan it sees no reason to do so with the protection of the American nuclear arsenal. However, if a conflict erupts with the North, South Korea could quickly evolve into a nuclear-armed state and pose even with the North with the support of the US in case a larger country gets involved in the conflict.
