IP8 Cryogenic Layout
2/26/2019
Meeting Goals
Procurement release for helium systemLooking for agreement on layout and installationReview any potential design change risks3D model sharingLiquid nitrogen system at 1008RD105-0508-050Who owns it?
IP8 Layout Agenda
Service building 1008B cold boxConnections to Blue Valve boxMulti-core cryogenics linesField jointsCryogenic bayonets and JumpersOff west (penetration) wallIP8 Cold box – Horizontal
Coordination List - Orientation
Service Building 1008B Cold Box
No platform for cold boxRelocation of vacuum pumpTemporarymove ofa rack for insertion (Don Bruno)Field joint will need scaffold for welding accessBuild off existing building features, foundation ledge
Service Building 1008B
Service Building 1008B Cold Box
(Building model hidden from view for clarity)Major Parts:Tap in connections at Blue valve box3 transfer lines with field joints1008B cold boxMulti-core cryogenic line leading to exterior
Multi-core cryogenics lines
Line runs along building wallUnistrut on wall1 footing support needed2 weld field joints
Multi-core cryogenics lines
Spool goes through shielding blocks at west wall penetrationJog in line needed from shielding configurationSpool inserted from outsideAction: Review radiation shielding at west wall
Shielding blocks shown translucent
Multi-core cryogenics lines – IP8
Manifold spool rests on main west wall platformPlatform extends from existing corner platform and ladderUpper platform needed to weld field jointAction: 2 platforms needed to support piping and welding
Upper platform
Manifold
Crane Limits to West Wall
1 Ton Crane44”
12 Ton Crane95”
West (Penetration) Wall
Crane Limits to South Wall
1 Ton Crane
12 Ton Crane
West (Penetration) Wall
Full Access to South wall
Multi-core cryogenics lines – IP8
1 ton crane should be able to rig manifold spool in placeUpper Platform considerations:Make permanent for penetration accessUse existing “window washer” platforms

Cryogenic Layout Review
No platform in 1008B service building to support cold boxBayonet manifold on west wall platform in IP8Platform needed with future connection to main deckA platform is need to complete IP8 field joint36.5 feet above top of railsConsider making that permanent
