The International Atomic Energy Agency (IAEA) will open its board meeting in Vienna Monday.

Discussions at the 35-nation Board of Governors meeting will include South Korea's recent acknowledgement of conducting secret nuclear activities. The five-day meeting is also expected to focus on North Korea's violation of IAEA safeguard agreements and Iran's alleged clandestine nuclear weapons program.

Discussions on South Korea's apparent violation of nuclear non-proliferation agreements are set to take place on Thursday.

The South Korean delegation to the board meeting is expected to acknowledge that Seoul partially violated IAEA obligations with the secret nuclear activities. However, the delegation will stress that the activities did not fundamentally nor intentionally violate the supplementary agreements of the Nuclear Non-Proliferation Treaty.

Earlier this month, South Korea acknowledged that a small group of scientists had conducted a one-time experiment four years ago that produced a minimal amount of enriched uranium. Last week, the South Korean government made another bombshell announcement, saying it had extracted a small quantity of plutonium in a secret experiment conducted some 20 years ago.
