12. Cooling and Ventilation equipments in the Shaft
Ducts in all points:
2 ducts DN1600 – machine area
2 ducts DN1300 – safe tunnel
2 ducts DN 2000 – underground cavern/UAs
1 duct DN1200 – pressurization shaft and lift cage – to be confirmed according to the layout of the concrete module.
In case of inclined tunnel, dimensions shall probably change substantially
In  points A, C, E, G, I, K
2 ducts DN 1200 emergency extraction from tunnel
Points D and J
We assume that the dump zone and collimation area can be ventilated with air taken from the underground cavern; if fresh air is mandatory, 2 additional ducts shall be needed.
Pipes
In all points:
2 pipes DN200 - primary water cooling (in some points it will be smaller but, for the time being we stick to DN200)
NB: in case there will be alcoves every 1 km in the tunnel, the diameter shall become DN300
2 pipes DN200 + lagging 40 mm all around – chilled water / this is for ventilation purposes, at present no request for chilled water is made
1 pipe DN fire fighting
1 pipe DN200 – make up water
1 pipe DN80 – compressed air
1 pipe DN80 – demineralized water make up
1 pipe DN100 – waste water (very rough estimate)
1 pipe DN200 – clear water drain (very rough estimate)
In Points where Cryogenic plants are installed:
2 pipes DN150
Point B, L:
2 pipes DN200 – RF underground plant
