EHN1 Extension Project
Jérôme Rodary EN-CV-PJ 2015/08/06
Contents 1. Works in progress
• Cold boxes works (Vertex 1&2, CMS, ATLAS H8)
• Fan coil for barrack HNA 494
2. North wall dismantling • Dismantling works (water networks, ventilation,…)
3. Future design activities• Future design activities : GAr extraction system, general
ventilation
• User requirements missing
4. Schedule – CV activities
1. Works in progress
• Cold boxes Vertex & CMS-RD5 • piping networks completed
• components & instrumentation installed
• next step : pressure tests (before 2015/08/14)
• final step : functional tests with the CB connected !

1. Works in progress
• Cold box ATLAS H8 (Saleve side) • piping & components supply in progress
• VIC done on 2015/08/05
• works will be done until end of august 2015
• New fan coil for barrack HNA 494 • cooling power 6,3 kW
• procurement launched
• installation in September 2015
2. North wall dismantling
• Works completed : • firefighting network interception
• chilled water disconnected barrack HNA 910
• mixed water station removed (north wall)
• old fan coil removed from barrack HNA 494
• raw water network interception (several places)
• Works to be scheduled before end of 2015 : • To be removed:
• ventilation ducts
• CW pipes & equipments
• drinking water loop
• To be rerouted: • compressed air loop
• demi water network
• raw water network
Specific care to asbestos !
3. Future design activities
• GAr extraction system : • pre-study in progress
• extraction flowrate to be frozen
• technical meeting scheduled on
friday 2015/08/07 regarding GAr system
GAr preliminary 3D model including extraction units & ducts
3. Future design activities
• Building general ventilation: • adding of 2 new ventilation units
• total flowrate: 210 000 m3/h
• total heating power: 2 440 kW

3. Future design activities
• User requirements missing EN-CV needs technical data & requirements for designing the future extended networks as listed below:
• chilled water (for HVAC purposes)
• chilled water (for cooling down other some equipments)
• compressed air
• raw water
• demineralized water
• domestic water (hot and cold)
• fire fighting system
• gas extraction (other gases except GAr ?)
• ventilation for cryostat assembly clean room
• other… ?
