Agenda Part 1: MP2.2 Schedule* Resource and schedule analysis Overview of the activities in the plasma vessel per module Work packages on the critical path, operational relevance Part 2: TR UHV-compatible assembly (1-NBT-T0025) Update vacuum requirements Annex 2 Task: Determination of hot leak tests *Time schedule does not take into account possible delays due to repair of fire damage in 2nd basement of torus hall.

Part 1 of this TKT: MP2.2 Overview and updates Overview Work planned in one shift: Mon - Fri from 7am - 3.30pm Diagnostic plan: Update since March 2023 Manufacturing work for TH-team has increased (to approx. 1/3 of all AP) Interlinking with assembly processes Compression and optimisation of assembly processes takes place Two module accesses omitted (approx. -4W) BUT: Duration of access to vessel modules shortened Work not yet considered: Determination / scheduling of leak tests according to TR 1-NBT-T0025 see part 2 of this TKT Repairs to some vessel components (e.g. CXRS shutter A122) Critical path, if applicable. No time alignment with any CoDaC APs that may be required Not currently planned. MAX PLANCK INSTITUTE FOR PLASMA PHYSICS | A. LORENZ | 06TH JULY 2023 TKT MP2.2 SCHEDULE 3
MP2.2 Update: Fluctuation of work packages NEW: P202 QHW Fast-Ion Wall-load monitoring Approx. additional 500h welding effort, but no qualification required Dropped: A062 ECE: Installation of cooling in AEE41 (Decision CCB 308) MAX PLANCK INSTITUTE FOR PLASMA PHYSICS | A. LORENZ | 06TH JULY 2023 TKT MP2.2 SCHEDULE 4
MP2.2 update: torn off tile in NBI beamdump Inspection heat shield: "Only" tile breakage - screw, gap protection grid, Sigraflex foil and heat sink apparently undamaged. Conical break-off cone of the graphite tile suggests excessive thermal stress of the hot graphite surface Next inspection 20 July checks TZM screws and threads Then CCB with determination of the repair measures Divertor target inspection No significant damage to CFC surface detected. Grinding qualified in principle as a repair method bottom divertor" MAX PLANCK INSTITUTE FOR PLASMA PHYSICS | A. LORENZ | 06TH JULY 2023 TKT MP2.2 SCHEDULE 5

Dealing with new AP, delivery dates and delays New AP Registration of new AP directly with E5-ENG/AV (arbeitsvorbereitung@ipp.mpg.de) Integration in MP2.2 plan after review and board decision if necessary Requirement and delivery dates in the DIA plan (9-EGD assembly planning_MP2_2) RO should regularly check demand dates/assembly dates (linking in WBS of DIA has been done). Attention: requirement dates are usually sharp dates; 4W central buffer was discarded. ROs are required to keep a suitable time buffer for the necessary requirement date. On the assembly date: RO must ensure own presence or qualified substitution Dealing with delivery delays Deliveries after the requirement date are only installed if the resources still available at that time allow it.

2. Part of this TKT: Annex 2 to Technical guideline on UHV-compatible assembly (1-NBT-T0025) Please note that the original guideline is in German and consult colleagues if in doubt over translation If you have any questions about this guideline and especially about Annex 2, please contact the colleagues of the vacuum group (E5-DEV/VE) and the quality management (QM). . Please determine facilities for carrying out UHV cleaning and UHV leak tests in consultation with the vacuum group MAX PLANCK INSTITUTE FOR PLASMA PHYSICS | A. LORENZ | 06TH JULY 2023 TKT MP2.2 SCHEDULE 15
Contents of annex 2 to technical guideline on UHV-compatible assembly 1. The instructions concern ... vacuum-connected systems that are dismantled, maintained, modified or extended during a W7-X maintenance phase and then reinstalled and continued to be operated. 2. Basically, all requirements from the TR UHV-compatible assembly (uid=28Y4DD, 1 NBT-T0025) must be fulfilled. 3. "Components" are typically: Plug-ins / immersion tubes installed in W7-X ports, Vacuum window, Components installed in the PV (KiP) and Components in systems that are vacuum-connected to the PV (e.g. diagnostics). 4. All work required during an MP under point 1 shall be carried out in accordance with approved QAAP. MAX PLANCK INSTITUTE FOR PLASMA PHYSICS | A. LORENZ | 06TH JULY 2023 TKT MP2.2 SCHEDULE 16
Vacuum barriers 5. As a rule, vacuum barriers of a component can be considered: a. the outer vacuum barrier: Main flange connecting the affected component to the W7 X PG and securing the PG vacuum. b. the inner vacuum barrier(s): Daughter flange(s) or other vacuum barrier(s) permanently attached to the component being serviced: built-in vacuum window, Media feed-throughs, Vacuum feedthroughs, which may have to be opened and closed again for maintenance. MAX PLANCK INSTITUTE FOR PLASMA PHYSICS | A. LORENZ | 06TH JULY 2023 TKT MP2.2 SCHEDULE 17
No renewed UHV cleaning and no leakage test: 6. no renewed UHV cleaning and no leakage test are necessary if: a. for maintenance work only the outer vacuum barrier is broken, the tightness of which is checked during the integral leak test during recommissioning. b. work is carried out consistently in a UHV-compatible manner in accordance with the TR UHV-compatible assembly, and in particular the component is consistently protected from contamination, and c. UHV-cleaned components are not modified, exchanged or processed. If in doubt, please seek consultation with experts from the vacuum group and QM. MAX PLANCK INSTITUTE FOR PLASMA PHYSICS | A. LORENZ | 06TH JULY 2023 TKT MP2.2 SCHEDULE 18
Necessity Leak test at RT mandatory: 7. Final leakage test at RT must be carried out if: a. for maintenance work, at least one of the internal vacuum barriers (e.g. media feedthrough) is broken, and b. the component (later) is not heated to T > 60 C permanently (i.e. also for a short time) during bake-out or operation. c. Special feature: VCR fittings in PV/port are only leak and pressure tested. The required test pressure for pressure tests is determined according to the test medium. the test medium (PA water pressure test - uid=2BX9CL, 1-NED-A0087; PA gas pressure test - uid=2BPGAE, 1-NED-A0087). If leakage test required, please schedule in WBS. Determine necessity with experts from the vacuum group and QM, if necessary. MAX PLANCK INSTITUTE FOR PLASMA PHYSICS | A. LORENZ | 06TH JULY 2023 TKT MP2.2 SCHEDULE 19
Necessity hot leak test mandatory 8. a final hot leak test according to PA hot leak test (uid=29NFJS, 1-NED-A0088) must be carried out if: a. at least one of the internal vacuum barriers (e.g. media feed-through) is broken for maintenance work, and b. the component is (later) heated to T > 60 C during bake-out or in operation (temporarily is sufficient). c. parts of the component are replaced or newly manufactured. d. parts do not or no longer comply with the UHV requirements according to 1-NBT-T0025. Identify the need for a hot leak test and test equipment with experts from vacuum group and QM, if necessary. If hot leak test is necessary, please schedule it in WBS and register it with E5-M. MAX PLANCK INSTITUTE FOR PLASMA PHYSICS | A. LORENZ | 06TH JULY 2023 TKT MP2.2 SCHEDULE 20
Summary - MP2.2 End date is currently 21 December 2023, but repairs on the 2ndbasement of the TH are not analysed. - Delivery dates in WBS of plants and projects are linked - also to design tasks in WBS EN - Please regularly check and update the WBS Delivery dates - Analysis of the new Annex 2 of the TR UHV-compatible assembly (1-NBT-T0025) required. - Please register any necessary hot leak tests as soon as possible.
