April 27-28, 2006/ARR 1 Finalizing ARIES-CS Power Core Engineering Presented by A. René Raffray University of California, San Diego ARIES Meeting UW, Madison April 27-28, 2006

April 27-28, 2006/ARR 2 Choose a Set of Machine Parameters to Perform Final Design and Analysis of Power Core Components From Jim’s and Laila’s presentations, the case with R=7.5 m would probably be the one with the lowest COE satisfying all our constraints However, we are using 90% 6 Li enrichment and have no active knob for increasing TBR if required during operation. We might have some margin with the 15% divertor coverage assumption. Should we choose the case with R=7.75 m with a somewhat lower 6 Li enrichment and slightly higher margin with respect to our constraints and requirements? ….and the winner is: R=7.5 m? NO, it is R = 7.75 m

April 27-28, 2006/ARR 3 We Have Made Good Progress on the Design and Analysis of Power Core Components, but There are Still a Few Areas Where We Need To Fill the Gap Divertor and Prompt Alpha Accommodation -Difficulty in obtaining results to define location and heat flux on divertor and regions that would need to accommodate the alpha loss. Continue our effort there (T.K. Mau) -In the mean time, we need to define zero-order parameters for our analysis -Suggestion: scale roughly from W7X divertor work and from our work to-date to locate divertor plates (for Laila’s analysis and also to provide a better estimate of the coverage fraction) (T. K. Mau) -For now, maintain the assumption of 15% coverage for divertor + alpha accommodation? -Need to agree on a core radiation fraction, a local divertor edge radiation fraction for a reasonable anticipated peaking factor on divertor (and for alpha deposition) and for a max. heat flux of 10 MW/m 2 (J. Lyon would need this also) -But we need some physics basis for the assumed numbers (T.K. Mau, J. Lyon)

April 27-28, 2006/ARR 4 We Have Made Good Progress on the Design and Analysis of Power Core Components, but There are Still a Few Areas Where We Need To Fill the Gap (cont.) Coil and Structure Analysis -Great that we can compare 2-D shell model results with 3-D solid model results for example case so that we can apply them to scale other shell model results -Need to analyze effect of penetration and rib requirement (X. Wang) -Zero-order estimate of structure thickness variation based on stress profile (X. Wang) -Need to choose between Incoloy and Japanese material (L. Bromberg) CAD Drawing -Need to update CAD drawings for our final design choices (no bucking cylinder) (X. Wang) -Do we need control coils and if so where are they located; need to show them on our CAD drawings (L-P. Ku) Blanket -Perform stress analysis on final design -First wall heat flux distribution (J. Lyon, L-P Ku) System runs -For both blanket designs (reference and advanced) (J. Lyon) -Availability assessment to back up our number (L. Waganer) Safety analysis -For both blanket designs? (B. Merrill)
