“…This conclusion is further confirmed in [6] where detailed results of transient FE thermal analyses of the TBM box are presented. In case of the steady state analyses presented here, a few localized hot spot occur in the front part of the horizontal SGs where too large portions of the material are not cooled adequately.…”

“…The cycles considered here are defined by the typical ITER pulse: 30 s ramp-up, 400 s at maximum power and 60 s ramp-down [3]. The test environment has to be vacuum to have the same conditions as for FW experiments.…”

“…To reproduce the high heat loads, a surface heater with fast response time and capable of generating a homogeneous surface heat flux up to 500 kW/m 2 is required [3]. Following an investigation of various heating methods it has been chosen to use an infrared radiation heater consisting of a tungsten filament inside a quartz glass (fused silica) tube with a reflective coating on one side of the tube.…”
“…The HCPB TBM design has been extensively described in [7][8][9]. The HCPB TBM features a box structure (EUROFER as structural material): the U shaped FW is closed along the poloidal direction by the lateral Caps; an internal structure of horizontal and vertical Stiffening Grids (hSG and vSG, addressed as sub-components together with the Caps) defines the volume allocation for the Breeder Units (BUs).…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
