Nuclear watchdog set to decide on 10-year lifespan extension for Kori units 3, 4
The country's nuclear watchdog was set to decide Tuesday whether to extend the lifespan of two nuclear reactors by an additional 10 years. The Nuclear Safety and Security Commission (NSSC) plans to hold a meeting to review a request to restart and operate two 950-megawatt capacity pressurized water reactors — Kori units 3 and 4 — that have reached beyond the 40-year designed lifecycle.

The Nuclear Safety and Security Commission (NSSC) in South Korea is set to determine on Tuesday whether to grant a 10-year extension to the operational life of two nuclear reactors, Kori units 3 and 4. These reactors, each with a 950-megawatt capacity, have already surpassed their original 40-year design life. Unit 3 was suspended on September 28, 2024, while unit 4 reached the end of its operational lifespan on August 6, 2025.
The two reactors are among nine aging plants that the state-run power operator, Korea Hydro and Nuclear Power (KHNP), intends to seek life extensions for. The NSSC previously granted a 10-year lifespan extension to Kori-2 lightwater reactor the previous year. This upcoming decision follows the commission's approval of an accident management program for the two reactors last month, which outlines safety measures to prevent accidents and mitigate potential fallout.
