The permanent shutdown of unit 1 of the Kori nuclear power plant has been approved by the South Korea’s nuclear safety regulator. The unit – the country’s oldest operating reactor unit – will be taken offline on 19 June. Kori 1 is a 576 MWe pressurized water reactor that started commercial operation in 1978. A six-month upgrading and inspection outage at Kori 1 in the second half of 2007 concluded a major refurbishment program and enabled its relicensing for a further ten years. A subsequent relicensing process could have taken Kori 1 to 2027, but Korea Hydro & Nuclear Power (KHNP) announced in August 2015 that it had withdrawn its application to extend the unit’s operating licence. In June last year, the company applied to decommission the reactor.
