Access Safety SystemsModifications & tests in 2006

Presented byRui Nunes

TS-CSE-AAS



Topics

• Introduction– SPS project organisation

• SPS Primary Access System– INB Constraints– Project & Implications for 2006 (and beyond...)– SPS from CCC

• PS Primary Access System– Control from CCC / CSA– Long-term plan & constraints

• PS & SPS Experimental Areas Access System– Ongoing project



Introduction

• TS-CSE-AAS (all projects)– PS team : R. Bonzano, D. Chapuis– SPS team : M. Grill, R. Villard

• SPS Projects– SPS Primary system reengineering

• P. Lienard : Project Leader• G. Robin, C. Arimatea – AB/OP collaborators

– SPS INB documentation and safety studies• E. Manola-Poggioli• S. Grau

• PS Projects– PS CCC

• F. Havart, L. Hammouti, O. Ratcliffe, J. Duran-Lopez - AB/OP– (S)PS Experimental Areas

• H. Nissen, F. Havart



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 Primary Access Safety System



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 from CCC

• Control from CSA since November 2005• Control from CCC planned from 4/Feb/2006

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
