1. Port Cell Area: replacement of TBM1. Port Cell Area: replacement of TBM

TBM Removal:

Step 1: Disconnect port plug and ancillary equipment, move AEU awayStep 2: Bring in transfer cask and extract port plug and move it to hot cellStep 3: Move and insert port plug into the hot cell “red zone”

TBM Return:

Step 4: Test of TBM and ancillary equipment at the hot cell areaStep 5: Disconnect utilities and put port plug on the transfer cask and move it to the port cell Step 6: Insert TBM, take transfer cask away and reconnect TBM with the ancillary equipment

AEU & transport TBM transfer cask

Cutting and re-weldingof PbLi pipes on the AEwill be done in a tent

Hot cell area

Mainly for the purpose of cost estimate, transfer cask to be supplied by IO

2. Hot Cell Area2. Hot Cell Area

Utilities: e.g. AC/DC, water, high pressure helium, diagnostics…etc., for the testing of TBM and ancillary equipment

Needs additional

• Hot cell “red zone” windows and services• RH equipment• Hot cell area for ancillary equipment maintenance• Utilities for TBM and ancillary equipment tests

• Since then at the TBWG-18 meeting, remote handling area presented the transport cask carrrying the tubes area and AEU

• EU group coordinated presentation with in-situ remote cutting and re-weld of tubes

• US presented a mostly hands-on port plug removal approach

• These are not only approaches and should be analyzed by parties
