Long-Term Plan for Managing Spent Nuclear Fuel in South Korea


By 2030, South Korea intends to operate 38 nuclear reactors, accounting for nearly 60% of the country’s power generation. This commitment to expanding its use of nuclear energy will result in an increase of Spent Nuclear Fuel (SNF). To manage this, the Korea Atomic Energy Research Institute (KAERI) used GoldSim to develop an “integration model” that predicts the generation, storage, transport, shipping, reprocessing and disposal of SNF and associated wastes over the course of the next 100 years.


The model is designed to evaluate various options including: constructing a repository for SNF and high-level waste, storing SNF at reactor sites or at centralized storage facilities, or using offshore or domestic SNF reprocessing facilities. It enables researchers to ask “what if” questions by evaluating various scenarios and determining the short and long-term implications. This innovative approach enables stakeholders, engineers and researchers to rapidly evaluate possible options and communicate their findings to all necessary personnel.
