Aging management of nuclear power plants in Korea
There is a dramatic change in nuclear industry of Korea during the last 40 years. This presentation consists of three parts. First of all, this paper describes energy, environmental crisis and nuclear power. And then it reviews current status of nuclear energy in Korea in the second part. Lastly, it will discuss the vision and challenges of nuclear industry. Since the first nuclear power plant (NPP) started its commercial operation in 1978, Korea has built and currently operated 21 NPPs with 5 additional NPPs under construction. KHNP which is a unique nuclear utility in Korea has four sites on Korea coasts, Younggwang in the west, and Kori, Wolsung and Ulchin in the east. Four CANDU reactors are in operation in Wolsong site, and 17 PWR reactors in Kori, Yonggwang and Ulchin. The total nuclear power generation capacity is more than 17,000 megawatts Korea has announced a long-term strategy that will determine the direction of its national energy policy until 2030. According to the plan, Low Carbon and Green Growth means a sustainable development in a low carbon society. Korea will reach its long-term energy goals by low energy consumption, increasing clean energy, boosting the green energy industry and affordable supply of energy. Nuclear power plants will account for 41 percent of the national power capacity in 2030, where as 24 percent in 2008. This presentation also shows the NPP aging management in Korea since 1990s. Kori Unit 1, which is the oldest nuclear power plant in Korea has been operated since 1978. As the number of aging plants rise, public concern over the safety of existing operating NPPs has increased. Periodic safety review (PSR) in addition to the existing safety assessments is proposed by IAEA as an effective way to verify that operating NPPs maintain the high level of safety. In this regard, the Koreas nuclear regulatory body, recently established an institutional process through revision to the atomic energy act to introduce PSR. This PSR considers, among other factors, improvements in safety standards and practices, the cumulative effects of plant aging, operating experience, and the evolution of science and technology. In particular, the assessment and management of plant aging is one of the major areas.
