Notes from December 2 meeting
Jim C.
Concerned that the installation of the flex joints will require
significantly more labor to install than the current joints due to the
restricted access to bolts. Tom Willard believes that the flex joints have
enough margin in them to reverse them (see attached images from Jim) and still
maintain a safety factor of more than 5. Tom will run the model with
reversed flexes to determine if this option is available.
Han
Presented a calculation (attached) showing the results of restraining the
ends of the outer TF legs with tension members to reduce the umbrella loads.
One option reduced the loads by approx. 45%.
Mangra
Danny reviewed the "Choke Points" tab in his attached spreadsheet. He
has identified a punchlist of items that need verification analysis by the
analysis group before he can proceed with the preliminary design.
Action: Dudek to meet with Mangra and Titus to work out need dates
and priority list of items.
Neumeyer
Presented the latest iteration of the OH conductor optimization and has
identified a 40kA combination that has the following advantages
but –increases PS costs by ~$500K.
•40kA
case w/0.275” hole
–cools
in 10 minutes
–delivers required flux in 1st swing
–Less expensive to
manufacture coil due to fewer turns
–Saves cost of high pressure cooling
water mods ($250k?)
Action: Dudek to obtain decision from Project management on whether
to pursue this option.
