N2 - The containment structures for the International Thermonuclear Experimental Reactor (ITER) include the plasma vacuum vessel, the structural supports for the in- vessel components, the gravity supports for the vacuum vessel and magnet system, the passive stabilizing structure, the internal fast active coils, and the cryostat vacuum vessel. Reference design concepts for all of these components have been prepared as part of the ITER Conceptual Design Activity (CDA) [1], for the standard ITER design point: Aspect ratio of 2.8, major radius of 6 m, central toroidal field of 4.8 T, and peak plasma current of 22 MA. A proposal has been made to improve the performance of ITER by modifying the reference design point. The high- Aspect-ratio design (HARD) proposal increases the aspect ratio to 4, increases the central toroidal field to 7 T, and decreases the peak plasma current to 14.8 MA. Systems studies [2] indicate that the HARD parameters provide improved technology testing capability by increasing the neutron wall loading while maintaining the CDA physics constraints (beta limit, energy confinement, etc.). Changes in configuration (Fig. 1), loading, stresses, and other factors for the containment structures components, based on the HARD parameters, have been investigated. The effects of these changes, both positive and negative, are discussed. The primary considerations are: Docs the HARD design meet all of the functional requirements? Does the HARD design resolve and/or reduce any of the technical problems inherent in the CDA design? Docs the HARD design create and/or exacerbate any technical problems? Are cost savings associated with the HARD configuration?.
