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?
