Present: A. Augustinus, L. Brarda, J. Caeyman, M. De Saegher, J. Fermanel, J. Lehrbach, L. Roy, H. Schindler, R. Schwemmer, Y. Seraphin, A. Tauro, W. Van Den Broucke, B. Vindevogel
Installation of the modules
- Power module and first two IT modules arrive in one convoy. Sequence of installation is up to CERN handling team.
- P2 installation: the mobile elevator will be installed on 11.9. The power module will be installed as first. Then the elevator will be moved to install IT1, and finally it will be moved again to install IT2.
- Visit with the transport company at Point 8 will be organised at the same time as the installation at Point 2. Solution for parking the lorries at Point 8 to be found.
RO installation
- After discussing with Lubron, it turns out that the RO installation should not be stopped completely during the winter months but kept in a "winter/standby mode" (flow rate to be quantified). As a consequence, the raw water supply lines need to be insulated and equipped with heating cables (Raychem).
- Automation to foresee a 16 A breaker in the power module for the heating cable.
- The valves to purge the raw water lines can be actuated manually and can therefore be kept. Control cable between power module and valve is not needed and will not be installed.
- Automation has discussed with Lubron what temperature to be expected for the RO water. At high water consumption (i. e. high throughput of the RO plant), the temperature should be close to the one of the raw water supply. At low consumption, it corresponds to the ambient temperature in the power module (outside temperature + approx. 5 degree).
- The first manifold box has arrived at Automation. RAMpower can go ahead with the assembly of the remaining boxes which will not be sent to Automation but directly to Point 2/8. Automation will send a drawing of the cut-outs to be made in the side panels.
Fire detection
- Michel has sent through pictures of the proposed locations for the fire detection equipment in the IT modules and the power module.
FATs
- ALICE FAT has been confirmed for 3/4 September. LHCb FAT tentatively scheduled for first week of October.
- Protocol for ALICE FAT is currently with the CERN procurement service. Johannes expects that it will be sent to Automation in the next days.
Action items
- Automation to update the structural calculations based on the comments received from CERN HSE.
- Automation to upload/send through structural calculations for LHCb.
- ALICE/LHCb to review the uploaded LCC/water consumption calculations.
- ALICE/LHCb to collate questions/comments regarding the documentation of the MODBUS registers.
- Automation to summarise Cyberhandler working point during hottest days.
- LHCb to send information which racks should have a cut-out in the side panels and their layout.
- Automation to provide written description of planned onsite work (cabling, electrical work etc.) for work-site safety assessment.
- Automation to send a drawing of the cut-outs in the manifold boxes.
- Automation to confirm date for LHCb FAT.
