South Korea’s first facility dedicated solely to storing radioactive waste will soon go into full operation, the facility’s state-run operators said in July 2014…The 1.56 trillion won (US$1.53 billion) facility in Gyeongju, 370 kilometers south of Seoul, was completed at the end of June 2014 seven years after construction began in 2007, according to the Korea Radioactive Waste Agency (KORAD)…The facility was completed more than 19 years after the government launched the project to build the country’s first-ever nuclear repository.
The government originally sought to build a nuclear repository for both high- and low-level radioactive waste, including spent nuclear fuel, in the coastal city of Buan, 280 kilometers southwest of Seoul. The plan was scrapped in 2004 after weeks of violent protests in the city that left hundreds of people injured. The facility was changed as a storage unit for only low- and intermediate-level radioactive waste, such as gloves, goggles and other equipment exposed to radiation at nuclear power plants.
Gyeongju volunteered to host the facility, but only after the government agreed to keep high-level radioactive waste, such as spent nuclear fuel, out of the city…Currently, the Gyeongju facility consists of six underground silos that can hold up to 100,000 barrels of radioactive waste and an examination facility that holds about 4,500 barrels of such waste waiting to be moved to the silos.
Already, South Korea has about 100,000 barrels of low- and intermediate-level radioactive waste from the past 36 years, since the country began commercial operations at its first nuclear reactor in 1978, according to KORAD. The country operates 23 nuclear reactors, generating about 30 percent of its total electricity supplies and 2,300 barrels of low- and intermediate-level radioactive waste each year.
A second-phase construction program is already underway to add an additional 125,000-barrel holding unit to the Gyeongju facility, which is designed to take in 800,000 barrels of nuclear waste over the next 60 years before it is completely sealed off. A KORAD official said it takes about 300 years for low- and intermediate-level radioactive waste to be neutralized.
South Korea is now beginning to discuss how it will manage spent nuclear fuel, but many say that determining where the high-level nuclear waste will be stored is the most crucial task.
