Overview
- The Nuclear Safety and Security Commission found Kori-2 maintains sufficient safety margins and cleared operations through April 8, 2033.
- KHNP must complete equipment replacements, after which the commission will conduct an on-site inspection before any restart.
- The decision is expected to guide life-extension bids for nine other aging units, including Kori-3 and Kori-4.
- Kori-2, the nation’s oldest active reactor, has been offline for about two years after 40 years of operation since 1983.
- The commission approved the plan in a 5–1 vote after earlier deliberations in September and October, with backers pointing to energy security, AI-driven demand and emissions goals.
