KSNP~+ construction permit review underway

摘要

Korea has been actively promoting nuclear power since the start of commercial operation of Kori 1 in 1978. A total of 18 nuclear units have now been put into operation providing 15,716MWe - about 40% of the total electricity capacity in Korea. By 2015 a further 11,600MWe will be in service, when a further six units now under construction and four more units planning stage, are completed. By then, nuclear power will fill more than 45% of the country's need for electric power. Table 1, showing the status and plan of nuclear power plants in Korea, reflects this. The Korean Standard Nuclear Power Plant (KSNP) has been developed between 1983 and 1991. Six nuclear units of this design have been built: Ulchin 3-6 and Yonggwang 5 and 6. In May 1995, the International Atomic, Energy Agency (IAEA) acknowledged that the KSNP represented a significant accomplishment in improving the safety of commercial nuclear power plants, after the agency carried out a safety review of Ulchin 3 and 4 as one of its expert missions. The details of the KSNP and Ulchin 3 and 4 designs were presented in the August 1992 and April 1998 issues of Nuclear Engineering International, respectively. Incremental design improvements have been continuously added to follow-up units of the KSNP.
