Subject: NCSX VV heating/cooling tubes and support FDR

 

Folks:

 

There will be an FDR for the NCSX vacuum vessel heating and cooling tubes and support hangers tomorrow, Thursday, May 5, at 9:00.  PPPL attendees will meet in the engineering conference room and call the ORNL attendees, who will meet in the L304 conference room.  Visual information will be shared via netmeeting.  The meeting particulars follow.  Please let me know if you cannot attend.

 

Thanks,

 

Brad

 

Charge:

 

Heating/cooling tube system

1.      Is the heating/cooling design (including trace tubing, manifolds, auxiliary heaters, and thermocouples) 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 supports

1.      Is the design of the VV 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.      Are the interfaces with other systems (primarily the mod coil shell) adequately defined? 

4.      Are the analyses complete and documented? 

5.      Are the design drawings adequate for procurement?
