Develop and test an internally cooled, cabled superconductor (ICCS) for large scale MHD magnets: Analysis report
A three-year program to develop and test an internally-cooled cabled superconductor (ICCS) for large-scale MHD magnets is being performed by MIT for the Pittsburgh Energy Technology Center (PETC) under contract DE-AC22-84PC70512. Included in this report are electromagnetic, thermodynamic, structural, protection, and systems analyses, completed as required to substantiate the preliminary conductor design requirements definition and the associated preconceptual magnet design developed in Task I. Copper-stabilized NbTi superconductor was selected at the outset as being most suitable for the application. The analysis necessary to substantiate the preconceptual MHD magnet design is complete, including field and force calculations, preliminary structural analysis, thermodynamic (cryogenic) analysis, and the analysis of the magnet electrical and protective systems. A significant result of the field analysis is the determination that maximum fields to which the conductor is exposed in the magnet are considerably higher than originally expected. Changes were made to produce a revised design in which the maximum field is 6.9 T (53% above central field) and adequate stability is ensured. Analysis necessary to substantiate a preliminary conductor design requirement definition for full-scale conductor has been completed except that further work is required to establish maximum allowable internal flow resistance and maximum length between vents. Procedures for accomplishing these analyses have already been developed at MIT and by other contractors. 11 figs., 11 tabs.
