Present situation I. Rühl 10 min
Dismantling works JL. Grenard 20 min
Cost estimates I. Rühl 10 min
Present situation ICARUS experiment and annexed equipment was transferred via
TIR tunnel and installed in EMPTY ‘B’ room of LNGS laboratory about 10 years ago.
Since then major modifications in TIR tunnel
Installation of fire resistant doors, which reduced clearance height from 4.75 to 4.6m
Installation of ventilation ducts, which reduces the overall height clearance along the tunnel to 4.6m
Installation of cryo-box restricting the clearance width to 4.3m in a curve B room
Installation of WARP experimental complex Installation of OPERA control rooms Installation of concrete step of 25cm height in center parallel to TIR gallery Increase of height floor by 30cm (expect TIR area)
Result of modifications
Free net passage at the door for a long, non tilted item is only about 4.05m

Removal procedure
Objects to be transferred
2 cryostats containing wire and tube chambers (ext. dimensions 3970x4403mm by 20’209mm of length) with unit weight of 48,5t
Structures and equipment for a total volume of ~1’800mc (26mx11mx10m – 2 tanks) composed of: 2 STEARLING tanks 3 pumping groups 96 electrical cupboards (racks) Cryogenic material (tanks, pipes, filters
etc), metallic structure, bulk material

Summary
Cost estimates – Preparation works
Preparation works Removing concrete step Removing OPERA CS2 Evacuation of all stored equipment Removal of the ‘neon’ part Removal of cryo-tank from TIR tunnel
Additional works for complete cryostat evacuation Removal of added 30cm concrete floor of about
20m length into the cavern Removal of doors and air duct
Costs to be evaluated by
INFN!
Dismantling works
Based on CERN experience the dismantling work of items that shall be transferred to CERN will require 1 crane drivers 2 handlers 1 mechanic 1 foreman / supervisor
for a period of up to 2 months.
These people must have many years of experience to work in confined underground areas.
CERN supervision of dismantling and handling activities is subject to approval by the CERN management.
