Risk Analysis 1. Usage limits Operating phases and procedures (2kW Thermosiphon) Control system (overall architecture) System users (accesses control) 2. Time limits (continues operation) 3. Space limits (Point 1, USA15, B3184 roof) 4. Other limits (properties of cooling fluids) Determination of the system limits Hazard identification – identifying the hazards and environmental aspects occurring in normal and exceptional conditions Risk estimation Risk evaluation 14/12/2011 M.

Cost Tracking Cost rise from 2010. Last budget presented to ATLAS management on 08/2011. Chiller N2 is not accounted. Cost are constantly tracked on EVM. The project has negative cost variance The project has negative schedule variance 14/12/2011 M. Battistin

Conclusions The TS detailed design is well advanced The equipment integration is still an important open issue. We shall start and operate the 2 kW to obtain insight for the functional analysis. Chiller construction is under-control. Condenser order has been sent. Support Piping installation is going to start In general the project is late and needs extra-resources to get the target date (Dec 2012): one Catia draftsman for 2 week to finalize 3D integration. one member of ATLAS ID collaboration will be welcome to join the team. a polish technician team for the assembly of the hydraulic part. resource to develop the PVSS/UNICOS control system shall be guaranteed. A workshop shall still be identified to give space and tools or the assembly! 14/12/2011 M. Battistin
