Agenda

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.
