Zarnstorff Cc: Gregory Pitonak; Jeffrey Makiel; Lyon, James F.; David E. Williamson; Fogarty, Paul J.; Martin T. Brown Subject: FW: VV FDR scope Folks There will be an FDR for vacuum vessel systems on Friday, September 16 at 1:30. The review will concentrate on the necessary design and documentation to support procurement and fabrication activities for the vacuum vessel parts and systems. This would include [1] heating / cooling system (including modified trace cooling tube configuration, the header and manifolding for the cooling tubes, and the heater tape, [2] lateral supports and manned access ports [3] thermal insulation and [4] I&C. There will be a second FDR to cover all the design, analysis, and documentation required to establish the design basis and support subsequent field period and machine assembly activities. The charge and committee are as follows: Charge: Heating/cooling system 1. Is the heating/cooling design (including trace tubing, manifolds, auxiliary heaters) adequate for temperature control of the vacuum vessel during standby, normal operation, and bakeout? 2. Are the interfaces with the diagnostic magnetic loops defined? 3. Are the interfaces with the cryostat feasible? 4. Are the analyses complete and documented? 5. Is the heating load within the capacity of the envisioned helium bakeout skid? 6. Are the design drawings and specifications adequate for procurement? VV lateral supports and manned access ports 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 and final assembly? 3. Is the manned access port adequate for initial operation and maintenance? 4. Are the interfaces with other systems (primarily the mod coil shell) adequately defined? 5. Are the analyses complete and documented? 6. Are the design drawings adequate for procurement? Thermal insulation 1. Is the thermal insulation system adequate to protect the modular coils and provide adequate insulation during standby, operation, and bakeout? 2. Is the design compatible with the baseline insulation fill material and with the known potential fill materials? 3. Are the part drawings ready for procurement? Local I&C 1. Is the instrumentation proposed adequate for standby, operation, and bakeout? 2. Are the thermocouples specified and ready for procurement? 3. Are the thermocouple locations specified?
