The Hanul No.1 nuclear reactor has restarted after suspension caused by a system failure in August last year.

The Hanul Nuclear Power Headquarters of the Korea Hydro & Nuclear Power Co. (KHNP) announced on March 2 that the Hanul No.1 nuclear reactor completed the planned preventive maintenance program and restarted after suspension caused by a system failure in August last year. It is a 950,000 kilowatt pressurized light water reactor.

The Hanul No.1 nuclear reactor resumed operation at 9:54 p.m. on March 1 and will reach 100 percent of output at 12:00 a.m. on March 4.

An official from the Hanul Nuclear Power Headquarters said, “We carried out detailed inspection for steel plates inside of the primary reactor containment at the Hanul No. 1 nuclear reactor, which was one of the old reactors supplied by the French firm Framatome, and confirmed the soundness of the primary reactor containment through integrated leakage tests during the latest preventive maintenance period.”

He added, “We improved safety by installing an external emergency cooling water injector at the nuclear reactor and confirmed that the reactor is safe through tests conducted in compliane with the related laws.”
