3. MICE Schedule Review 24 th May 2011 Work package overview –The Hydrogen Delivery Systems will provide liquid hydrogen to the Absorbers in MICE –Each Absorber will have a dedicated delivery system (A, B & C) –The systems use metal-hydride storage and an R&D phase is planned to de-bug this novel part of the system –The R&D phase uses a dedicated test cryostat in place of the final MICE Absorber –Upon completion of the R&D, the system will be integrated with the AFC containing a KEK absorber for final commissioning 3

4. MICE Schedule Review 24 th May 2011 What we have to do...to test the system 4 Heater/Chiller units for the hydride bed Test Cryostat Ventilation System (continues on the roof) Hydrogen Charging Station Vacuum Pumps (more on the roof) View of MICE Hall South Side (mezzanine not shown) Gas Panel Enclosure AND Pass a pre-operation safety review Vacuum lines

5. MICE Schedule Review 24 th May 2011...to be ready for STEP IV 5 AFC module in STEPIV position Gas Panel Enclosure moved up the mezzanine New vacuum line Ventilation extract duct moved

6. MICE Schedule Review 24 th May 2011 What we have done so far 6 Test Cryostat Ventilation System Gas Panel Enclosure Vacuum Pump Enclosure Vent stacks Control System

7. MICE Schedule Review 24 th May 2011 Tasks –Controls –Mechanical Design –Safety –Hall Infrastructure and Installation –R&D Testing –STEP IV Preparation (AFC Commissioning) 7

8. MICE Schedule Review 24 th May 2011 People  M Hills - project management, cryogenic and mechanical design  M Courthold - cryogenic design, controls and testing  T Bradshaw – advice and consultation on cryogenic issues  I Mullacrane, P Warburton - control system design and implementation  A Muir, S Postlethwaite (with supervision from A Grant) – mechanical design  Hall technicians – installation and assembly 8

9. MICE Schedule Review 24 th May 2011 2011/12 Schedule Overview 9

10. MICE Schedule Review 24 th May 2011 Controls 10 –Controls for helium testing already in place –This work covers the additional tasks for hydrogen testing

11. MICE Schedule Review 24 th May 2011 Mechanical Design 11 Mostly laying the foundations for integration with the AFC

12. MICE Schedule Review 24 th May 2011 Safety 12 –Working closely with consultants to ensure DSEAR and IEC61508 compliance –Plenty of documentation to prepare

13. MICE Schedule Review 24 th May 2011 Infrastructure and Installation 13 EMR run will push back several tasks, but work can continue on external infrastructure during this period

14. MICE Schedule Review 24 th May 2011 Testing 14 –Helium testing to start once power and water in the Hall are restored –Second EMR run may delay some hydrogen testing

15. MICE Schedule Review 24 th May 2011 STEP IV Preparation 15 –Repositioning of Gas Panel Enclosure and related services is driven by completion of R&D testing –AFC commissioning extends into May 2012

16. MICE Schedule Review 24 th May 2011 Milestones 16 MilestoneDate Helium R&D testing completeJuly 2011 Safety Review passedAugust 2011 Hall infrastructure and installation completeSeptember 2011 Hydrogen R&D completeDecember 2011 Manufacture of items for AFC adaption complete November 2011 AFC Commissioning completeApril/May 2012

17. MICE Schedule Review 24 th May 2011 Risk Summary –Funding availability –Manpower restrictions/key staff availability –Would impact all aspects of the project –Hydride bed has been affected by long term storage –A concern given that a direct replacement is no longer available –Safety review recommends major design changes before R&D testing can commence –Significant knock-on effect for STEP IV –R&D system manufacturers are unwilling or unable to take on contract for systems B & C –Would result in delays to transfer knowledge and require closer oversight of the new contract from STFC 17

18. MICE Schedule Review 24 th May 2011 STEPS V & VI –This means Systems B & C in the context of the Hydrogen Delivery System –Most of the hall infrastructure (e.g. vacuum enclosure, ventilation system, gas supplies) will serve all three systems, so it is ‘only’ the hydride bed, gas panel, transfer lines and control system that are required –If R&D system is successful design can be carried over with very few changes –Type of hydride bed is currently the major unknown as the current manufacturer, Treibacher, no longer supply an equivalent model –Each system will take approximately 1 year to design, manufacture and test with an AFC module (full Gantt chart available) –Current assumption is that work in System B will start in April 2012 with System C following in April 2013, but this is highly dependent on the overall project schedule 18

19. MICE Schedule Review 24 th May 2011 Summary –Detailed schedule is known for System A installation and the R&D testing –This is due to be completed by the end of 2011 –MICE running to commission the EMR will impact the current plan and may delay this date –Significant work following R&D testing to prepare for AFC commissioning and STEP IV –Delivery of Systems B & C should be in line with their need-by dates, but hydride bed supply issues need resolving 19
