ITER storage and delivery system R&D in Korea

The tritium storage and delivery system (SDS) is one of the main components of the ITER tritium plant. There are several R&D activities on-going for the detailed design. The verification of design parameters of the SDS beds has been performed. Several types of ZrCo beds are under investigation to obtain desirable rapid delivery and recovery performance and to establish the pertinent procedure of in-bed calorimetry. An experimental apparatus is prepared to develop technologies for the process integration and verification of the SDS. The performance test of a tritium compatible metal bellows pump is executed and the results show a reasonable agreement with the catalog data of the pump. A SDS bed simulator has been developed to simulate the various bed operation scenarios under normal and abnormal conditions. A prototype is fabricated and the bed operation scenario generation program to be applied to this simulator is developed. The design requirement of tritium loading station calorimeter is prepared based on a benchmarking mock-up calorimeter.
