ISIS TS 1 Project: Shutdown & Commissioning planning Stephen Gallimore Project Manager for the ISIS TS 1 Project ICANS XXIII – Chattanooga, TN, USA 15 th October 2019

Contents • • Introduction Planning & Strategy Pre-installation testing Shutdown Strip-out & installation Commissioning Summary

Introduction – Project Overview • 9 years • £ 15 M Close-up of the target, reflector and moderators (TRa. M) • Sustainability project to secure the operational future of ISIS TS 1 CAD render of full target trolley showing TRa. M & services trolley

Planning & Strategy Pre-installation testing Pre-beam commissioning What do we need to do to be ready for beam? Ready for Beam With beam commissioning Operations What do we need the beam to do?

Planning & Strategy • Overall commissioning strategy document – High level aims – Description of lower level documents – Layout of phases with expecting timings • Work package commissioning plans – Equipment specific – What is being tested and why – Discussion of scheduling and resources • Specific testing plans – – Testing procedure Tolerances of acceptance Non-conformity & defects Sign-off

Planning & Strategy High-level strategy Keep target within operating temp. range Work package commissioning plans Controls – temp. sensors & signals Services – water systems Componentlevel testing plans Controls logic Setting and checking alarm & trip levels Step by step flow test sheet

Pre-installation testing • Site Acceptance Test – Dimensional checks – Sub-set of FATs • Functional operation and mechanical fit – Flow rates & pressure drops – Alignment & adjustability • Basic controls system operations – Sensors reading sensibly – Valve operation Replica reflector and 3 D printed moderator heads on the new cantilever frame. TS 1

Pre-installation testing • Regular (maintenance/removal) remote handling – Disconnection and reconnection of services – Putting in a flask – Taking a target in and out of a storage well • Recovery from off-normal scenarios – For example, recovery from a dropped TRa. M component A view through the Zn. Br remote handling cell window on TS 1

Pre-installation testing • Procedure practice – Reduce time and dose to workers – Clear thinking in emergencies – Feeds into safety documentation required • Important to have sensible hold points – Sign off equipment as ready – Note any non-conformities & rectifications – Feedback parameters into design calculations • Permission to strip-out existing redundant equipment • Have agreed criteria • Prerequisite to starting shutdown • …once strip-out begins there is no going back!

The Long shutdown • 12 months off for TS 1 but cycle(s) run on TS 2 • Planned to begin Sep 2020 • Rough breakdown of timings: – – 3 months strip-out 3 months install 3 months pre beam commissioning 3 months with beam commissioning • First few cycles after start up, there will be disruption

The Long shutdown Some of the challenges: • Resources – Remote handling operatives – Shared resources (numbers and dose) – Two parallel working fronts (RHC & TSA) • Work flow bottle-necks – Main hall crane – Waste acceptance processes – Shared resources (? )

The Long shutdown Some of the challenges: • Working environment hazards – – Trolley movement Multi-height parallel working Radiation dose Ambient conditions • Other large projects during shutdown – Linac tank IV replacement – Riken refurbishment – Instrument projects (various)

RHC based strip out A CAD image of the current TRa. M design with the reflector cut-away to show internal components

RHC based strip out • • Most major items have been removed before Only cantilever frame has never been out Frame will be cut in half* Have clear, controlled and well practised procedures from removal and extraction of equipment • Highest dose rate items but very limited chance for exposure • Each item will be put into a shielded storage container *For more information please see the poster: ISIS TS 1 Project – Removal of the Target, Reflector and Moderator (TRa. M) Support Structure using a Bandsaw within a Remote Handling Cell. By Ross Turnley – 17 th Oct @ 16: 30

TSA based strip out A photo from the construction of the target services trolley (circa 1983) showing the vast array of services’ pipework

TSA based strip out • A lot of equipment to remove • Plan to remove highest dose rate items first i. e. filters, IEx columns & water pumps • Have clear waste plan for how to deal with all the different types of waste/waste items • Much work will require RPE as well as PPE • Work to utilise hydraulic cropper for cutting wherever possible • Workers will be exposed to many hazards, so training and preparation are essential

Installation • Much equipment design in modular fashion to aid installation • Greater attention paid to remote handling features • Have worked closely with the operators of the equipment in the design phase • Most equipment will have been assembled & tested prior to installation • For RHC installation, aim is to minimise amount of remote handling work required • More care required than for strip-out!

Commissioning without beam • Checking of connections and fit into greater system • Full without beam process and control functions: – – Flow water through TRa. M components Cool-down and flow cryogens for moderators Perform drain/vent/maintenance procedures on systems How to deal with non-conformity and deviations • Installation complete • Hold point - Sign off of equipment and systems – Mechanical – Controls – DSEAR/ATEX

Commissioning with beam • Radiation protocol and monitoring • Staged commissioning with increasing power steps – Need to provide expected beam requirements to accelerator team – High enough power to get meaningful heat loads – Keep power as low as possible to minimise activation – Check parameters against designs – Will require some instruments to open shutters • Commissioning complete • Hold point – Hand over to operations

Summary • Outline Commissioning plans in existence, detailed commissioning and resource plans to be developed • Schedule is tight: – Late delivery has an impact on pre-install testing – Delays during strip-out & install ‘squeeze’ commissioning – Resources constraints & bottle-necks • TSA strip out likely to lead to highest doses to workers • Must have robust and practiced procedures • Hand-in-hand relationship with safety documentation

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

Back-up slides

Pre-installation testing TRa. M components: • Alignment • Where possible functional tests; i. e. water flow • Cutting saw final practice cuts Target services area components & systems: • Basic water flow & valve operation testing • Simplified control system • Cold and vacuum testing on cryogenic equipment • ATEX room inspection • Not populating drag-chains prior to installation with electrical cabling
