SLAC LCLS-II 2K cold box

SLAC LCLS-II 2K cold box

Outstanding design issues

• move 2k cold box north to create clearance for transfer line
• clear all interferences created by moving cold box north (move control cabinets and manway)
• make configurations of model to show what is in scope of AL, remote assembler, shipper, field installer, and operator
• make it possible to add shear pins to assembly AFTER delivery to reduce maximum shipping height
• add straightener assemblies to CC inlet spools
• thermal relief design iteration
• heater final design based on finned tubing and heater cartridge quotes
• MLI attachment
• details of instrumentation tubing and panel arrangements
• incorporate internal shipping and seismic supports as a result of piping flex analysis

Questions

• can overall height be reduced any lower than 14 ft?
• can we get a more accurate weight estimate?
• is it possible to ship in this configuration?
• what will be the expected shipping loads (accelerations)?
• can we cut the shipping costs a LOT by making small changes to the dimensions?

Completed

• (in coordination with Randy) decide where to locate the process relief/blowdown; we have decided to move this into the scope of the interface box
• (in coordination with Cindy) decide whether to move north to create clearance for next transfer line; YES
• (in coordination with Cindy) decide whether to coordinate 9-1/4" bayonet heights and locations with next transfer line; NO these bayonet heights will not be coordinated
• add 6" o-ring ANSI flange for diffusion pump connection
• publish corrected model of CC inlet and outlet spools to allow the flex analysis to proceed
• lower 9-1/4" bayonets and valves to reduce maximum shipping height
• move process relief/blowdown iteration out of the scope of the 2k box
• make initial estimate of shipping size and weight
• How to attach spools to outlet nozzles of small CCs (especially CC6)
• Manway downsize; NO
