SPS Access Safety System - INB
• The SPS is now considered as part of an INB– “Installations Nucléaire de Base”
• Compliance problem– current SPS Access Safety System is
• PLC-based • Not redundant• Does not comply with the major criteria sought by the
INB authorities :– Common cause of failure

SPS Access Safety System
• Compensatory measures– Phase 1 - 2006 During Run
• Interlocking of 4 critical access doors in AUG !!• Blocking / Condemning all other doors
• SPS Reengineering – Phase 2 - 2006-2007 shutdown
• Development of a separate cabled loop to provide redundancy to PLC system (like LHC)
• Preparing for complete replacement of SPS Access Safety & Access Control Systems
– Phase 3 - 2007 and beyond• Deploy new access control in a phased manner

SPS from CCC
Consoles are being put in place as we speak– “Old” LEP consoles (ugly
consoles – sorry…)
– Will stay until new SPS access system is functional
– 1 day access interruption to reconnect cables and test

SPS from CCC
• SPS Access system has to be completely re-tested after 1 year of complete shutdown– 2 weeks technical verification– 3 days final testing before run
• Operation guidelines shall be given to AB/OP by project team– Patrol before run– Opening of machine

PS from CCC
• PLC-based safety signals– Key interlocks– Via optical fibres
• Supervision Hardwired Virtual– Hardwired console replaced by TIM
Virtual console
• CCC or CSA (not both)– Possibility to delegate to CSA if
needed during shutdown– No beam operation possible from

PS Primary Access in the Long term
• PS Access system is an ageing system– Has suffered many modifications and has many layers due to
different technology for each modification– Must be replaced soon
• Not possible to maintain actual system much longer
• Should be replaced by LHC-type Access • Main difficulty
– PS has doors not “SAS” or turnstiles– Doors do not guarantee unique passage– Solution
• Either install “sas” or turnstiles• Or accept CCC operator supervision (maybe not acceptable)
• In any case investment is high but necessary– Risk is high : no PS no SPS no LHC beams

PS Experimental Areas
• Project to revamp PS Experimental areas has continued– Delayed by the PS CCC project– Implementation objective :
• AD Experimental area access control for 2006 Run• East Hall revamp during 2006-7 shutdown
– Extension to SPS if according to need
• Safety PLC-based system– 1 PLC per zone– 1 master PLC concentrator per “Super Zone”– Interface by physical pin matrix for zone re-configuration– Documentation available for the moment
• EDMS URD : 476292, SRD : 478678, ADD : 503535
• Accounts for requirements of PS and SPS– can be supervised remotely by the CCC via TIM

Conclusion
• CCC– No major problems in sight, but last phase due in the coming
weeks
• SPS Primary– Tight schedule constraints and uncertainties as to SPS
Access Control system renovation
• PS Primary– We have made the last major change (CCC) that will ever be
made before renovation is due
• (S)PS Experimental areas– A project constantly delayed by other projects
