The Gyeongju nuclear waste disposal facility is of silo-type design involving disposal at depth meant to safely house dangerous radioactive waste at Gyeongju in South Korea. Storage of Low to Intermediate Level Waste (LILW) was planned. In its first stage its design allows for 100,000 barrels of storage; upon completion in the final stage a total of 800,000 would be accommodated. South Korea’s nuclear program is fully integrated into the national infrastructure, supplying 30% of its electricity, and 8.6% of its total energy usage. As of May 2012, a total of 21 reactors operated in the country generating 18.7 GWe. Ongoing and planned projects are estimated to bring South Korea’s generating capacity to 32.9 GWe by 2030. Waste, of low and intermediate levels, was stored on site at each plant; however, after nearly 30 years of energy generation from nuclear power on-site storage began to fill. Without a separate storage facility, the government of South Korea estimated that the storage pools within the Kori Nuclear Power Plant, Ulchin Nuclear Power Plant, and Yonggwang Nuclear Power Plant would have filled by 2016, 2018, and 2021, respectively. The CANDU facility at the Wolseong nuclear power plant would have filled by 2017. Plans for storage facilities were being drawn as early as 1986, however it was not until 2005 that a site was able to be selected: Gyeongju. After obtaining the permits for the project from the MKE, and the construction and operation licenses from the MEST, construction was able to start on site by August 2008. By 2010, 1000 drums of LILW waste had been shipped and stored at the not-yet completed site at Gyeongju; this was to be the standard-size shipment to be received on site. Construction was completed early into 2013 ==Background and Geology of the Gyeongju area== Gyeongju, located in a sediment filled basin within the extreme southeast corner of the North Gyeongsang province of South Korea, boasts a population of 269,343 people as of 2008. In the past Gyeongju was the capital city of the ancient kingdom of Silla and is now a culturally rich attraction. The area designated for the disposal facility sits within the Gyeongju Basin, which is built mainly of sediments intruded by plutonic rocks. It is approximately 1.1 km by 1.8 km, with the Wolseong CANDU nuclear power plant to the south. The disposal facility will sit above an area composed primarily of granodiorite; to the north a small portion is underlain by biotite granite. Nearby are the Taebaek Mountains, formed through ancient thrust faulting and subsequent fault-block motion, whose eastern reaching ranges form a steep fault line stretching to the coast. Korea is relatively geologically stable, though the Taebaek may experience slow, but ongoing, tectonic uplift. The regions main source of water is the Hyeongsan River. Regional topography consists of hills of elevation ranging from 100 to 250 meters with an overall slope eastward towards the sea. Streams mirror this eastward trend and empty out towards the sea. Groundwater flows generally in an easterly direction, dependent on topographical hills, ridges, and valleys. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Gyeongju nuclear waste disposal facility」の詳細全文を読む スポンサード リンク
