R&D activities on helium cooled solid breeder TBM in Korea

R&D progress of Korean HCSB TBM

“…Korean helium cooled solid breeder (HCSB) test blanket module (TBM) has been designed considering the performance of DEMOrelevant solid breeder blanket [1][2][3][4]. It uses helium with a small fraction of hydrogen to purge tritium gas produced inside the blanket.…”

R&D status of key technologies for the development of KO TBM

“…It has been designed accounting for the performance of DEMO-relevant blanket [1][2][3][4]. The lithium ceramic breeders and beryllium neutron multiplier are used in pebble-bed forms; they are tested in TBM for the purpose of tritium release and heat extraction demonstration.…”

“…Various joining methods for reduced activation ferritic-martensitic (RAFM) steel, which are expected to be necessary for TBM fabrication, have been studied [3][4][5]. To define TIG welding conditions for RAFM/RAFM steel, two conditions with different currents were applied to 10 mm-thick plates.…”
