S. Korea’s Saeul-3 Nuclear Reactor Granted Operational Clearance

(MENAFN) South Korean authorities granted operational clearance Tuesday for the Saeul-3 nuclear reactor, paving the way for commercial electricity generation beginning in 2026.

The APR1400 reactor—engineered and constructed domestically—sits within the Saeul Nuclear Power Site in Ulsan, a major southeastern port city. Construction commenced in 2016, according to a Seoul-based news agency.

A six-month trial operational phase will now proceed before full commercial deployment.

Choi Won-ho, chairperson of the Nuclear Safety and Security Commission, defended the approval process in an official statement: "In accordance with legal procedures and on scientific and technological grounds, we have thoroughly inspected the safety of the Saeul-3."

The commission chief emphasized ongoing oversight measures: "We plan to continue strictly checking safety through pre-use inspections during nuclear fuel loading and the test-run process."

Regulatory approval arrived roughly two weeks following the commission's decision to delay its final determination during an earlier review session.

Saeul-3 represents a milestone as South Korea's inaugural nuclear facility specifically engineered to survive direct aircraft strikes.

The reactor features extended spent fuel storage capacity spanning six decades—sufficient volume to accommodate all radioactive waste generated throughout its complete operational lifespan.
