The gravity supports are composed of pedestals with flexible elements to allow radial displacements. The magnets are supported fully independently of the vessel and associated components.
(a) The magnet system provides the following:
(1) TF coils for the magnetic field that gives the designer-specified plasma safety factor during the various phases of operation.
(2) TF coil structures that are integrated with the PF coil supports and the CS structures to restrain the electromagnetic loads on the coils under normal operating and fault conditions. The TF coil structures also resist the gravity and seismic loads of the magnet system.
(3) CS for the majority of the magnetic flux change needed to initiate the plasma, generate the plasma current, and maintain this current during the operation time. The CS contributes to the fields needed to control the plasma.
(4) PF coils for the magnetic fields that shape the plasma and control its position during the various phases of operation.
(5) CCsthatcompensateforfielderrorsduetodesign asymmetries and geometric tolerances in the machine.
(b) The magnets must withstand the following conditions:
(1) electromagnetic loads acting on the magnets
(2) the weight of the magnets
(3) seIsmic loads on the magnets
(4) forces applied during installation and assembly of the magnets
(5) helium coolant pressure loads
FAB-1.220 Magnet Structures
In a tokamak, the TF magnet Is subjected to two main force systems. The in-plane loads are generated by the interaction of the current in the TF coils with the toroidal field. The out-of-plane loads are generated by the interaction of the current in the TF coils with the poloidal field. In most instances, the TF coil cases are the main structural component of the magnet system, and they provide support against the TF coil in-plane as well as out-of- plane loads.
FAB-1221 Magnet Structural Arrangement. The TF coil casing encloses the winding pack and is the main structural component of the magnet system. The TF coils are structurally linked. The coil case is fabricated from an engineering material, such as stainless steel or an equivalent material. The TF coil structures support the self-equilibrating electromagnetic forces acting between the TF coils, the CS, the PF coils, the CCs, and the VV during normal operation, plasma disruption,and fault events.
The vacuum vessel
(a) provides a hazardous materials confinement barrier and withstands postulated accidents without losing confinement
(b) is designed to remove the nuclear heating and maintain the surface heat flux within the allowable temperature and stress limits
(c) is designed to remove the decay heat of in-vessel components, even In conditions when the other cooling systems are not functioning
(dJ provides a pressure boundary consistent with the generation and maintenance of a high-quality vacuum
(e) supports in-vessel components to specified tolerances and their loads under normal and off-normal operations
(I) together with the in-vessel components, maintains a specified toroidal electrical resistance and contributes to plasma stability by providing a conductive shell tight fitting to the plasma as far as practically feasible
(g) together with the blanket, divertor, and ancillary equipment in ports, provides adequate radiation shielding for the superconducting coils and reduces activation inside the cryostat and at connecting ducts (end parts of the port extensions) to facilitate remote handling and decommissioning
(h) provides access ports or fecd-throughs for in-vessel component service and maintenance, maintenance and inspection equipment, fueling and pumping systems, diagnostics, and plasma heating equipment and test blanket
The main components that make up the VV are the main vessel, the port structures, and the VV supporting system. The tokamak VV is a torus-shaped structure with shielding and coolant. The basic vessel design is an all-welded structure. Only the inner shell serves as the first confinement barrier when the double-wall structure is employed. The VV is divided into sectors joined by welding.ASME FE.1 pdf download.
