1 EN-CV Progress EHN1 Extension Project
Jérôme Rodary EN-CV-PJ /10/01

2 Contents 1. Works in progress 2. North wall dismantling
Cold boxes works (Vertex 1&2, CMS, ATLAS H8) Fan coil installation for barrack HNA 494 2. North wall dismantling Dismantling works (water networks, ventilation ducts,…) 3. Future design activities Future design activities : GAr extraction system, general ventilation User requirements missing 4. Schedule – CV activities

3 1. Works in progress Cold boxes Atlas & CMS piping networks completed
components & instrumentation installed pressure tests done final step : switch from drinking water to raw water

4 1. Works in progress Cold boxes Vertex 1&2 (Jura side)
new branches identified for connecting these CB Impact & VIC scheduled week 41 works / tests will be done as soon as possible final step : switch from drinking water to raw water Date to be confirmed by TE-CRG (14th of december 2015 ?) New fan coil for barrack HNA 494 cooling power 6,3 kW Installation will be performed on 13 & 14 October

5 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  Planning slightly updated due to asbestos constraint (GS & CV) !

6 3. Future design activities
GAr extraction system : pre-study in progress first 3D model sent to MEF for integration model updated after comments GAr preliminary 3D model including extraction units & ducts

7 3. Future design activities
Hall general ventilation: adding of 2 new ventilation units total flowrate: m3/h total heating power: kW  WP in progress Existing ventilation unit inside EHN1 building

8 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… ?

9 4. Schedule – CV activities
Tâches désamiantage/dépose GS & EN Début Durée estimée Intervention préalable à la connexion du réseau eau potable (côté Jura, au dessus du local R-101/R-102) / Travaux avec nacelle disponible dans le bât. 887 In progress 01/10/2015 1 jour Coupure et dépose tuyauteries Eau Glacée des réseaux du mur nord (derrière les barracks) / EN-CV-OP fera la vidange du réseau à partir du 21/10/2015 26/10/2015 1 semaine Coupure et dépose des tuyauteries d’Eau Glacée (Chilled Water) dans la gallerie technique Coupure et dépose des tuyauteries d’Eau Potable (Drinking Water) côtés Jura & Saleve et mur nord Fin décembre 2015 – date à confirmer avec TE-CRG 2 semaines – à confirmer  Dismantling planning review to be done (MEF & CV)
