  1. Target Technical BoardNick SykesJuly 2016

  2. Baseline design has been through ESS PDR

  3. Technical Update

  4. Technical Update • Confinement and shielding have developed intrabay door and transfer hatch design • Handling Has Developed Primary Remote Handling Tool Design and it’s recovery • Size reduction developing tasks and technologies inline with component interfaces • Control system architecture devised

  5. Component Transfer Hatch • Feasibility study has been completed. • Concept has been developed to CDR stage. • Changes to the Active Cell structure have been agreed in time for concrete pour. • Detailed requirements are being developed. • CDR documentation is underway. Hot Side – Process Cell Cold Side – Penetration Room

  6. Upper Intrabay Door • Feasibility study with an industrial partner has been completed. • Concept has been developed to preliminary design stage. • Preliminary embedment geometry and loads have been provided to ESS. • Maintenance Cell to High Bay recovery penetration locations have been provided to ESS. • Detailed requirements are being developed. • CDR documentation is underway. Upper Intrabay Door Door Actuation Upper Intrabay Door Mechanism– Maintenance Cell

  7. Other equipment • Costs for all confinement and shielding equipment have been established via industrial engagement • An initial list of equipment interfaces has been established • Early engagement to define the cask – active cell interface has begun • A detailed set of requirements for all confinement shielding equipment is being developed and inputted to IBM DOORS

  8. Primary Remote Handling Tool • Design substantiation with an outside contractor completing a feasibility study of the bridge mounted servo-manipulator design. • A FMECA workshop to analyse failure scenarios of the PRHT. The retrieval of the PRHT to the Maintenance Cell was identified as an area of concern due to complex lifting operations. • Sub-system requirements capture to develop a PRHT design specification, estimated loads, dose rates and duty cycles on the PRHT. • Beginning to developing operation sequences to estimate performance requirements for the PRHT

  9. Crane System • Bridge mounted servo-manipulator Primary Remote Handling Tool retrieval development exploring different design for hoisting and transporting a failed PRHT and alternative crane designs to mitigate risk of a complex rescue of the PRHT. • Further sub-system requirement capture to develop design specification to procure cranes, including estimates of duty loads, maximum design driving lifting operations etc. • Engagement with external crane designers and market research.

  10. Through Wall Manipulators • Market research identifying solutions for additional in cell manipulators. Considering both nuclear sector through wall manipulators and industrial style robots. • Beginning to developing operational sequences to generate requirements for additional in cell manipulators. Estimating values for reach, mass, location and dose rates.

  11. Size Reduction Tasks are progressing • Requirements Capture In Progress • Initial Size Reduction system requirements capture is complete, awaiting entering into DOORS database. • Interface requirements capture is ongoing. Recent effort has focussed on developing the MRP interface. • Initial concept developed for a system that can process the Target Wheel and MRP. • Other components require assessment against this system, dependant on component design maturity. • Cutting trials suite being developed to test the unique Process Cell requirements.

  12. MRP Interface Developing the following key areas: • Lifting interface with the MRP crown • Cut section information including: • Loose internals of cryolines and other coolants • General materials properties of cuts due to irradiation hardening • Lifting interface of beryllium cassette • Extraction cassette for PIE sample torpedo

  13. Concept Process Cell Layout • MRP Cutting Layout • Band saw station for shaft cutting. • Milling Station for Frame break down and PIE sample extraction. • Target Wheel Cutting Layout • Band saw station for shaft cutting. • Milling Station for Wheel break down and Tungsten Cassette extraction. • Target wheel rotation station and band saw station for wheel shroud breakdown.

  14. Controls Progress As per the method outlined in the kick off meeting, we are iterating through the engineering life cycle phases. At this point we have completed a first sketch pass: • analysing the high level architecture • plant breakdown structure • explored design considerations • evaluated resource options

  15. Controls Progress

  16. Controls Progress This has provided us with enough outline information to determine: • scope of work • interface requirements • a draft BOM • preliminary project schedule

  17. Controls Progress Our analysis has led us to the conclusion that it would be wise to implement a phase plan in order to meet agreed delivery schedules while at the same time ensuring a realistic strategy will yield a robust product.

  18. Controls Progress Productive discussions and meetings with the ESS team have enabled us to proceed with a second iteration, defining interfaces and capturing requirements. • reviewed existing ESS documents • interface discussions with ESS departments

  19. Controls Progress

  20. Controls Progress Moving forward we are managing the Active Cells requirements through the use of IBM Rational DOORS. This will provide us with: • data integration • hierarchy and document management • baseline and version control • linking to ongoing systems engineering activities • ensuring lifecycle traceability and validation • filtering stakeholder views of complex systems

  21. Equipment Can be Sourced with Qualified to the Total Integrated Dose • Dominant impact around target shaft removal. • Total Integrated Dose is achievable
