F4E Annual Report 2009 - Fusion For Energy - Europa

completion of details. The structures are now dividedinto two well-separated packages of approximatelyequal value: Coil-Casings (18 sets) and Outer IntercoilStructures plus Gravity Supports (18 sets). A precisesharing between Voluntary Contributors within the EUwas agreed in the summer of 2009.In the context of the JT-60SA Integrated Project Team,a formal review by external experts (panel chairedby R. Aymar) was also conducted in the summer of2009. The panel concluded the review favourablyand agreed that the design is mature to proceed withprocurement initiation.The technical specification for the High-T c-Superconducting (HTS) current leads was completedand the interfaces were agreed with JAEA. The designof the current leads is largely based on the designfor the current leads for the W7-X project. The finaldesign review was successfully completed. High-Tc superconductor material was already orderedin advance because of its long delivery time. Thetechnical level of the Procurement Arrangement andthe Agreement of Collaboration was agreed betweenF4E and the Voluntary Contributors by the end of 2009.In the field of Power Supplies, the Europeancontributions for the JT-60SA Power Supply (PS)system include the Base PSs for the Toroidal FieldMagnet, the CS and EF coils, High Voltage generatorsfor CS1-4 modules to provide the requested voltagefor plasma breakdown, Quench Protection Circuits(QPC) for all superconducting coils, PS for In-vesselcoils for Fast Plasma Position Control (FPPC), and PSto control RWM.In the course of 2009, the technical and procurementpreparation activities have proceeded in accordancewith the Work Programme and according to thereference schedule. Relevant interface documentswere developed, details of the sharing were concludedTF Coil Conductor Sultan SampleView of JT60SA cryostat base and one TF Coil with structuresand drafting and finalisation of the TechnicalSpecifications documents has been progressingwell leading to the conclusion of the ProcurementArrangement of the QPC as well as the finalisationof the Technical Specifications and PA material forthe Base PS and High Voltage (HV) generators (theconclusion of which is planned for mid-2010).A complete model of the JT-60SA Poloidal Fieldcoil circuit including all the passive structures wasdeveloped. The model was updated on the basis ofthe new geometric data of the Vacuum Vessel andstabilising plates, and it was utilised to analyse theeffects of plasma initiation, disruption and of QPCintervention in terms of over-current.Two different complete models of the JT-60SA BasePS system (including Motor Flywheel Generators(MFG)) were developed to verify MFG compatibilitywith the JT-60SA electrical loads and the thyristorconverter performance. The obtained active andreactive power waveforms are utilised to design theAC power system.ANNUAL REPORT 2009 FUSION FOR ENERGY39
