In-pile testing of ITER first wall mock-ups at relevant thermal loading conditions in the LVR-15 nuclear research reactor

摘要: Abstract The TW3 in-pile rig enabled the thermal fatigue testing of ITER primary first wall mock-ups in core nuclear reactor. This experiment investigated neutron irradiation influence on design performance under high heat flux testing. A 0.5 MW/m2 field LVR-15 reactor was applied. Within scope tests with simultaneous irradiation, reached a record 17,040 cycles radiation damage range 0.41–1.17 dpa depending material. Even after number cycles, while being irradiated by neutrons, no tested visually observed. Further and analysis will follow Forschungszentrum Juelich.
