Fracture and Creep in an All- Tungsten Divertor for ARIES Jake Blanchard University of Wisconsin – Madison August 2012

Introduction The ARIES Project is exploring the feasibility of using tungsten as a structural material for plasma-facing components For now, we are assuming the material is pure tungsten, but alloys may be necessary This talk addresses two key failure modes that must be addressed by these designs ◦ Fracture ◦ Thermal creep

The Design

Major Input Parameters ParameterValueUnits Surface Heat11MW/m 2 Volumetric Heating17.5MW/m 3 Coolant Pressure10MPa Bulk Coolant Temperature 600C

Crack Location Crack-Free Stress State Finite Element Model with Crack on Coolant Channel Surface

Fracture Results Results for Crack on Previous Slide Results for Crack Perpendicular to Cracks Shown Results for Crack in Notch (at shutdown)

Effect of Transients Surface Temperature Temperature 2.5 mm below surface Vary nominal heat flux by +/-20% and apply 20 cycles No discernible variation below surface

Surface Effect of “Small” ELM Assume 1.95 MJ deposited on divertor surface over 1.2 milliseconds Melt layer is 20 microns thick

Thermal Creep Add Thermal Creep Model for Tungsten Creep rates are excessive at 11 MW/m 2 Nominal Heat Flux Reduced Heat Flux

Design Modifications Varying Surface Heating or Coolant Pressure Reducing Notch Depth

Conclusions We have not identified any “show- stoppers” with respect to an all-tungsten divertor for ARIES Many uncertainties are still unresolved
