Previous works
ITER AEU frame structure structural analysis
MAST BES diagnostic thermal analysis
ITER CXRS shutter actuator thermal analysis
ITER EQPP 1 thermo mechanical analysis

ITER CXRS shutter actuator
Description of the task
CXRS port plug
ITER cryostat
EFDA task under the direction of FZJ
Shutter
Main aims - temperature field of shutter
actuator - necessity of additional cooling -
optimal wall thickness of bellows
8
ITER CXRS shutter actuator
Description of the appliance pneumatic
structure main parts are two bellows inside each
other axial shift is controlled by the gas
pressure two plates are fixed to the base two
internal plates are pushed by the actuator
Loads and boundary conditions internal heat
generation constrained temperatures temperature
dependant convection radiation
Temperatures

ITER CXRS shutter actuator
Results max. temperature 187
C permissible temperature 300 C no critical
regions
10
ITER CXRS shutter actuator
Conclusion additional cooling is
not necessary temperature differences are not
significant all the wall thicknesses can be
adequate
Wall thickness 0,3mm
