A plan to dismantle the nation's oldest nuclear reactor, the Kori-1 reactor, has been finalized. 

The Nuclear Safety and Security Commission on Thursday approved the Korea Hydro and Nuclear Power Company’s plan to deconstruct Kori-1.

The decision came 47 years after the reactor first began commercial operations and eight years after the initial decision to permanently halt its operations. 

The country will witness the dismantling of a commercial nuclear power station for the first time.

The Korea Hydro and Nuclear Power Company will spend a little over one trillion won, or some 790 billion U.S. dollars, through 2037 to disassemble Kori-1 and will use the site where the reactor had stood for industrial purposes.
