Surface storage

  • Discussion started with Raul for the Steel frame
  • Filter Y or T
  • Check valves
    • Refrigera 0.3bar best candidate
    • Check the leak report
    • Run cobra simulation to confirm the DP is not too large (Bart) 1valve on the siphon supply, 2 on the siphon return
  • Routing exhaust
  • DP pipe heater
  • Coiled HX
  • Vessel specification
  • AEV specification : To be done assap because long delivery time (Jerome Paolo)
  • Vessel specification : Bart send to Paolo this week to start reviewing the document


  • Superheater sizing done for accu and plant
    • 40 plate for plant
    • 90 and 70 plates for "high power" CMS TK1, TK2, ETL and low power for the rest. Jerome made the good point that for CE, the load that is given in the table is "begin of life", at end of life it will be 70kW , this detector was the high power case for "low power" superheater the report will be update to show what will be the DP at this power.
    • Agrement was sent to JohSjo to start ordering the HX
