The government said that the step is in line with the decision of the Korea Electric Power taken in October that outlined the disposal of the reactor parts.
The power company said about $58.7m worth of parts secured from the unassembled Korean Peninsula Energy Development Organization (KEDO) reactors should be taken over to be used as future spare parts.
A total of KRW1.1bn ($991,100) worth of materials will be sold as scrap metal while other partially assembled components worth KRW300m ($270,300) will given to laboratories and schools.
The detailed studies have commenced to find out whether the parts such as cooling pumps are compatible with the 1,000MW and 1,400mw reactors currently in use in the country.
The KEDO consortium, jointly created by South Korea, US and Japan, was responsible for the construction of a light-water reactor nuclear power plant in North Korea under the 1994 agreed framework between Pyongyang and Washington.
Under the agreement, the North froze its nuclear activity in return for US commitments to provide two commercial reactors, Bernama.com reported.
