Update of the ARIES-CS Power Core Configuration and Maintenance

An update on the ARIES-CS power core configuration and maintenance approach based on NCSX-like plasma and coils, with a focus on modular maintenance and field period clearance. Includes layout of power core components, arrangement of supporting legs, cooling access tubes, and motion studies for field period maintenance.

  1. Update of the ARIES-CS Power Core Configuration and Maintenance X.R. Wang S. Malang A.R. Raffray and the ARIES Team ARIES Meeting  Madison, Wisconsin September 16, 2004

  2. Outline • Update of the ARIES-CS power core configuration based on NCSX-like plasma and coils, and field-period based maintenance approach. • Update of the ARIES-CS power core configuration for modular maintenance approach.

  3. Layout of the Power Core Components Based on Circular Plasma and Planar Coils(OLD) Major Features: • The supporting tube of each field period is enclosed by a separate cryostat. • Bucking cylinder to react the centering forces of coils is enclosed by a separate cryostat in order to be maintained at cryogenic temperature. • All the individual cryostats containing the entire coil system and the supporting structure are enclosed by an external vacuum vessel.

  4. Layout of the Power Core Components Based on NCSX-like Plasma and Coils Cross-section at 0 degree Cross-section at 60 degree

  5. Arrangement of Supporting Legs to Support the Weight of the Blanket/Shields • There is nearly no limitation on the cross section of the warm legs because the warm legs are between warm regions. • The shield rests on warm legs, transferring the weight of entire power core(~10,000 tons) to the foundation. • 2x2 strong warm legs are needed each field period(2 units/one period) to support the weight of blanket/shields.

  6. Arrangement of Cooling Access Tubes to FW+Blanket+Shields Major Features: • All the access tubes are from the bottom as concentric tubes. • Sliding joints can be used at the inner tube. • Only outer tube has to be cut and re-welded.

  7. Motion Studies To Verify Clearance for the Field-Period Maintenance Approach(OLD) 60 ° 50 ° 40 ° 30 ° 20 ° 10 ° 0 ° It is feasible to move the replacement unit out in toroidal direction for a combined(blanket+shield) thickness of 100 cm after shaving a minimal shield.

  9. Layout of the Power Core Components Base on Modular Maintenance(at 0 degree) (OLD) (NEW) • Updated the components (based on the NCSX-like configuration): • Geometries of the components • Supporting tube, bucking cylinder, and supporting legs • Vacuum vessel

  10. Layout of the Power Core Components Base on Modular Maintenance(at 60 degree) (OLD) (NEW) • Updated components (based on NCSX-like configuration): • Geometries of the components • Supporting tube, bucking cylinder, and supporting legs

  11. Future Work • Look into the NCSX-based configuration with more details, for example, the layout of the coolant supply pipes, cold supporting legs, warm supporting legs and cable connections at bottom. • Look into the field-period maintenance approach with more details, for example, how to control the spread of radioactivity during maintenance operation.
