CERN Safety Alarm Monitoring (CSAM)

CERN Safety Alarm Monitoring (CSAM)
CERN Safety Alarm System Supervisory Board 8th
meeting Luigi Scibile CSAM project team

Mandate (Reminder)

• Provide a Safety Alarm system covering
  acquisition, transmission, logging and display
  for all the CERN sites, the LHC machine, LHC
  experiments and experimental areas.
• Requirements defined by the AL3S working group.
• Mandate covers
• System specification
• Prototyping
• Tendering
• Design
• Installation
• Integration.
• Operation Maintenance

Current status
Safety alarms require the immediate
intervention of the fire brigade and are defined
at CERN as 'Alarms of Level 3' (AL3S)

Status report (Since last Supervisory Board)

• Currently at the END of workpackage 1 - phase 2
• Realisation completed
• Factory Acceptance Tests running (see R.
  Bartolome)
• Preparing for the Workpackage 2
• Deployment plan for the LHC installation
• CSAM included in the EVM
• Budget - within cost to completion
• Planning - aligned to LHC planning
• New financial plan

System Realisation highlights

• Integration of the firemen intervention drawings
• Validation by TIS representatives
• Validation by the TCR representatives
• Quantitative safety validation
• The final system has been simulated for the
  evaluation of the RAMS figures and they are
  compliant to our requirements (SIL2).
• Following the HazOp analysis, additional
  modifications and procedures were added to
  minimise, prevent or eliminated potential system
  failures.
• FAT includes tests for the safety validation

Overall planning

• Five months delay respect to the latest planning.
• Problems with some delay/realisation issues
  (SOLVED)
• Problems with the integration tests (SOLVED)
• No additional costs on the system
• Installation plan under revision with the firemen
  and the safety equipment groups
• For the LHC it means the order of installation
• These changes are foreseen in the contract

8
Overall budget

• The project is on budget
• A new financial plan was prepared to include the
  realisation delays.

Short-term milestones

• Factory Acceptance tests completed by 19/9/2003
• Site installation completed by 10/10/2003
• Acceptance Testing by November 2003
• If acceptance successful CSAM
  OPERATIONAL in SCR and TCR

12
Conclusions

• CSAM within budget
• CSAM delays not in the LHC critical path
• New financial plan in line with previous
  estimations
• Difficulties encountered by the contractors have
  been solved
• Realisation meets technical and SIL2 safety
  requirements
