  1. ISIS TS1 Project progress summary Stephen Gallimore Project Manager for the ISIS TS1 Project ICANS XXIII – Chattanooga, TN, USA 15th October 2019

  2. Contents • Introduction • Progress Summary • TRaM • Target services trolley • Looking to the future • Work still to do • Long shutdown • Future work • Summary & acknowledgments

  3. Introduction – Background • ISIS produced first neutrons in Dec 1984 • ISIS was originally expected to have an operational life of 20 years; but we’re still going strong! • Original Target station 1 (TS1) design utilised a uranium based target • Until the operation of TS2 (2009) TS1 ran at 50Hz View of monolith inside TS1

  4. Introduction – Project Overview The TS1 project is part of ISIS’ commitment to ensuring the ongoing sustainability of the facility. It will: • Secure the future of TS1 and enable it to operate for many more years • Provide improved flexibility for future target or moderator changes • Make current operations of the target station easier • Provide a neutron performance increase, of up to a factor of 2, on some instruments • Provide confidence in the ongoing operation of TS1 to enable future instrumentupgrades • Improve our knowledge and skills in target station design for future projects

  5. Introduction – Project Overview • £15M (2015 pre-Brexit prices) – yes, this has changed • Implementation phase 2016 – 2022 • As of Oct ‘19 – 66,000+ staff hrs • Hugely interdisciplinary Close-up of the target, reflector and moderators (TRaM) CAD render of full target trolley showing TRaM & services trolley

  6. Progress summary - Reflector • Machining and Ni-plating now complete • Preparing for FATs at the end of month • Delivery past ‘Brexit’ deadline • Have also had an aluminium ‘mock’ reflector assembly made Technical team behind plated reflector blocks during recent visit For more information please see the poster: ISIS TS1 Project - Reflector Engineering Development By Dan Coates – 17th Oct @ 16:30

  7. Progress summary - Reflector • Contacted by supplier in June • Error in manufacture had led to cracked Be (shown right) • Not all smooth sailing • Very fortunate we had ‘spare’ material Image showing damage to beryllium block 111

  8. Performance Overview - Reflector assembly Photo of full reflector assembly prior to plating

  9. Progress summary- Target assembly • Operational target complete • 2nd Target in production • Plates, vessel and spacer piece already in production • Will be using a stainless steel replica target during initial testing For more information please see the poster: Measurement and Simulation of Decay Heat in the ISIS TS1 Target By Dan Wilcox – 17th Oct @ 16:30

  10. Progress summary - Cryogenic moderators • Methane now features a dual (poison) foil design • Methane transfer line also being replaced – being fabricated at present • Looking to establish a framework for longer term • Hydrogen – complicated production Assembly drawing of methane moderator

  11. Progress summary- Services skid construction • Major water services components installed • Pipework welding underway (onsite) • ATEX room delivered and under construction • Services construction completion due by Feb 2020 & testing by May 2020 Photo of current status of modular services trolley in R106

  12. Progress summary- Cryogenic cold boxes • H2 box nearing completion • CH4 box still in manufacture • Despite close supervision and regular contact, supplier is well behind schedule • Limited in what SATs we can carry out prior to installation Photo of internals of hydrogen cold box

  13. Looking to the future- What still remains • Shielded containers for waste removal • Moderator production • Controls • Pre-installation testing • Readiness review – Dec 2019 • Long shutdown: • Strip-out • Installation • Pre beam commissioning • With beam commissioning Section view through reflector flask

  14. Looking to the future- Long shutdown • Planned to begin Sep 2020 (subject to review) • Also features large accelerator and instrument projects • 12 months off for TS1 but cycle(s) run on TS2 • Significant resource, safety and scheduling requirements • Plans to cover all of this are in place but need further development …Subject of another talk at ICANS XXIII – up next!

  15. Long shutdown Long shutdown Long shutdown ISIS-II decision Looking to the future- Future work Larmor, IMAT, ChipIr, ZOOM TOSCA, MAPS, MARI, OSIRIS Instrument projects/Endeavour ESS Instruments RIKEN-RAL refurbishment Harwell Fac Building TS1 target implementation TS1 target feasibility Linac Tank IV Linac Tank I ISIS-II feasibility ISIS-II studies ISIS-II design ISIS-II construction *Don’t have all the funding fixed for it yet

  16. Summary • On track with schedule, scope & cost • … but challenges remain • Firm dates in place for long shutdown (subject to review) • Resource constraints have impacted on timescales and spend • As equipment arrives heavy reliance on operational team for assembly, alignment and testing • Provisional plans already in place for the shutdown – need development • Already looking to build on the TS1 project for ISIS-II

  17. Acknowledgements My sincere and genuine thanks go to all those whom have provided information and direct input to this presentation and its associated paper & to the whole project team! A photo of many of the team involved with the TS1 project

  18. Acknowledgements A shameless and blatant plug for other related work: • Dan Wilcox • Two Methods for Measuring Residual Strain in ISIS Target Plates • Measurement and Simulation of Decay Heat in the ISIS TS1 Target • Ross Turnley • ISIS TS1 Project – Removal of the Target, Reflector and Moderator (TRaM) Support Structure using a Bandsaw within a Remote Handling Cell • Dan Coates • ISIS TS1 Project - Reflector Engineering Development • Dan Pooley • The ISIS TS1 Project: Instrumentation for the measurement of the moderator time structure and neutron flux across the ISIS instrument suite. • … and me again

  19. If you have any questions I would now be happy to take them Thank you for your Attention

  22. Progress summary- Cantilever support frame • 1st frame complete & being tested (in conjunction with mock reflector) • Will rod-out issues before making 2nd later this year • Has been used for fitting-up flexible water pipes for welding Image of cantilever frame with a replica reflector assembly
