Brown Subject: VV manned access port and lateral support FDR Folks There will be an FDR for the vacuum vessel personnel access port and associated lateral support hardware on Thursday, November 17 at 1:30. The personnel access port represents a modification to the standard NB blank cover that is part of the VVSA assembly. The lateral supports keep the vacuum vessel centered and carry all net toroidal and lateral loads. These components were reviewed at the FDR in September, but there were open chits that had to be resolved prior to procurement. This FDR will present the final final design with all chits closed. The charge and committee are as follows: Charge: 1. Is the design of the VV lateral support system adequate for normal, fault, and handling loads, including upgraded first wall and a full complement of diagnostics? 2. Do the supports have adequate capability and adjustment to facilitate field period assembly, final assembly, and motion during cool-down and bake-out? 3. Is the personnel access port adequate for initial operation and maintenance? 4. Are the interfaces with other systems (primarily the mod coil shell and cryostat) adequately defined? 5. Are the analyses complete and documented, including stress in the port assembly and heat leak to the mod coils? 6. Are the design drawings adequate for procurement?
