An inspection team from the international nuclear watchdog IAEA has completed its investigation at Kori 2 reactor in Busan. According to available reporting, the team found commitment to operational safety, but said further improvements were needed.
The mission ran from 26 October to 12 November 2026 at Kori 2, a pressurised-water reactor of around 1,000 megawatts. The investigation took place at the request of the South Korean government and focused on how the plant organises its day-to-day safety.
For such investigations, the IAEA uses an Operational Safety Review Team. International experts examine procedures, maintenance, training, operations and how an operator learns from previous incidents. This is an assessment of operational safety, not a licence for a new reactor.
The available public source reports that the team found a clear commitment to safety and continuous improvement. At the same time, it made recommendations. Without the full mission or final report, it is not possible to establish precisely which measures are mandatory, which recommendations are voluntary and within what timeframe the operator must respond.
Kori 2 is located at the Kori nuclear power plant near Busan. South Korea uses nuclear power as part of its electricity supply and is extending the operating lives of some older reactors after additional assessments. This gives extra weight to oversight of maintenance and ageing.
For the surrounding area, an international safety mission does not mean that a new incident has occurred. It is a periodic review of operations. Nor does its outcome automatically indicate that a reactor is unsafe; recommendations are customary in international peer reviews and must be followed up separately.
The IAEA generally publishes a more detailed report or summary after a mission. Until that primary publication is available, caution is needed when drawing conclusions about the seriousness of the recommendations. The central news is therefore that the mission has been completed and that both positive findings and areas for improvement have been reported.

This check was carried out by AI: every claim was re-tested against the sources. Even an approved article can contain errors — stay critical.
The limited core claim was confirmed by a public secondary source. Because the primary inspection report is missing, specific details about the recommendations have not been presented as established facts.
- confirmed The OSART mission at Kori 2 ran from 26 October to 12 November 2026. — This is stated in the public summary of the mission. source
- confirmed Kori 2 is a pressurised-water reactor with a capacity of approximately 1,000 megawatts. — The same public summary gives reactor and capacity details. source
- confirmed The team reported both a commitment to safety and opportunities for continuous improvement. — This is the core of the published summary. source
Editor's note
The date and main findings are available through a public secondary source. The full IAEA final report containing the specific recommendations was not found; the status is therefore insufficient_sources.Sources
