CC3 Outlet – CC6 Inlet Sections
CC3 Outlet - CC4 Inlet, CC4 Outlet - CC5 Inlet, CC5 Outlet to Bayonet and CC6 Inlet to bayonet sections are very similar to the CC2 Outlet – CC3 Inlet section. Nozzle loads for normal operation meet requirement. Code Stresses are far below the allowable stresses. Anchor is the same design as it on CC2 Outlet – CC3 Inlet section. Anchor is strong enough for the transportation load. LCLS-II 2 K CBX FDR, Mar 9, 2017

Conclusion Load case Conclusions Operational (sustained and expansion)
Loads on CC casing nozzles are less than the operational allowable loads Transportation Stresses are less than the code allowable stress of SS304L The anchor supports are strong enough to support the transportation loads Seismic (sustained, expansion, and occasional) Stresses are less than the code allowable stress
