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… ?
