Development of HTGR-coated particle fuel technology in Korea Original Research Article

The status of R&D works being carried out for the development of the technology for the coated fuel particles and the achievements in the first phase in Korea is described. Emphasis is given to the development of the laboratory equipment and apparatus and the first results of the experiments carried out for the kernel preparation and coating of PyC and SiC as well as their respective characterizations and relevant quality control (QC) methods. The current status of the in-reactor performance model and the analytical code development are included as well as some preliminary results from the feasibility study on the irradiation test of the fuel specimens in the HANARO research reactor in Korea. Also discussed are the essential involvements in the GIF collaboration and with the IAEA as well as other international collaboration schemes during the development.
