  1. ICARUSCold VesselsThermal insulation Project progress report

  2. The Cold Vessels and thermal insulation of ICARUS, which is running (successfully) to day in LNGS, will not be re-used at CERN for several (good) reasons. These fundamental parts of the detector are designed ex-novo by external specialists. Mechanic structures: A. Castellani Thermal Insulation: GTT The good integration of their projects and the technical performances control is crucial and is our job.

  3. Typical vessel transversal section (1-1).

  4. Wall and corner aluminium alloy extruded shapes.

  5. Corner assembly.

  6. Top wall.

  7. Removable end cap.

  8. ContainmentDetailed Description • Standard components • Industrially pre-fabricated by independent suppliers Stainless steel corrugated membrane 304 L – 1.2 mm Primary Barrier Pre-fabricated membrane sheets Plywood Composite material Secondary Barrier One block Pre-fabricated panels Reinforced polyurethane foam Plywood Mastic Concrete wall covered with a moisture barrier Insulation in TPS(1) area Insulation above 5m height (1) Thermal Protection System

  9. ModularInsulating Panels • 1m wide by 3m long • Typical range of thicknesses : between 250 to 350mm Flat panel with TPS* Metallic component onto which the primary barrier is welded Plywood boards Secondary barrier Insulation layer Flat panel without TPS* Plywood boards *Thermal Protection System

  10. Design Concept at TPS Level Continuity of the Secondary Barrier by bonding Tight Primary Barrier Tight Secondary Barrier Closed primary space Closed secondary space CONCRETE

  11. Design Concept Above TPS level Primary space (Only one space) Liquid tight Primary Barrier CONCRETE

  13. Conclusion Last Monday we met at CERN representative of both Parts and we organised together with them the future work, based on the present results. The principal open problem was the mechanical project of the supporting system of vessels into the thermal insulation, ensuring the requested rigidity, but reducing thermal bridges. Another important option was the definition of the thickness of the insulating material vs the requested performances (10 W/m2); such a value will be guaranteed with 60 cm thickness on the bottom and 40 cm elsewhere.
