[en] The Republic of Korea started its program on nuclear energy development in the late 1950s. The first power generation reactor started producing commercial electricity in 1978. In 1983, Korea started its long-term project on the standardized nuclear power plant design (KSPNP). At the present, nuclear energy provides almost 40% of the total electricity generation in the Republic of Korea. The technology transfer program and technological self-reliance initiative of the Korean nuclear power generation community have been successfully executed to the point that Korea is now capable of exporting her nuclear power generation capabilities and sharing her know-how and developmental experience with other developed and developing nations, which need nuclear power generation in order to secure energy supply for sustainable development
