REX10 interconnection and environmental greenhouse gas reduction in south korea

In this paper, we introduce REX-10 (regional energy reactor, 10MWth) system development and power system interconnection in the utilization sides of renewable energy resources for the purpose of reduction of environmental greenhouse gas emissions. The REX-10 consists of nuclear reactor power generation units with thorium fuel. We describe the assumed strategy for power interconnection between the island areas and a KEPCO (Korea Electric Power Corporation) power system. The electric power capacity for the regional power generation per unit has less than 10 MW of power output. The newly designed REX-10 has been developed to be placed in an island ares to maintain system safety, island, etc. Also, REX-10 units for distributed generations (DGs) are connected to the backbone transmission line of a KEPCO 154 kV power system in South Korea. Additionally, this study on DGs using REX-10 is necessary and important with respect to the environmental energy policy for greenhouse gas reductions in Korea. Thus, we expect reduced carbon dioxide emissions of 6.448 million tons as compared with what coal-fired power plants would emit if they were to generate the same amount of electricity.
