SCT in UJ33

  • During the 24hr heat run major problems were found (for a more detailed description see the attached file):
1 - Over-heating of the systems in UJ33 (central part) – TS-EL will re-routing the cables inside the UJ33.

2 - Over- heating of the cables in the tunnel side RZ33 – a vertical cable tray will be positioned parallel to the TS-CV cooling water supports. The tray will host one of the three cable layers that are now placed on the same tray.

  • The re-routing cable works will last approximately up to the third week of June. The integration/cost studies are on going and the possible co-activities interfering with the preparation for the cooldown of the A34 are being taken into account.
A meeting to up-date the "status of the art" is foreseen for Monday 14th. Details will be given.

  • During the inspection of the UJ33 P. Proudlock commented:

1 - ODH system must be foreseen in UJ33 - the DFBLC inside the UJ makes it indispensable

2 - Rectangular ducts (for the geometers) must be closed during the heat-run

Comments: HEAT RUN CANCELLED

  • Maintenance of the water-cooling circuits coming form Point 2 providing water also to the cooling circuits of the power converters in UJ33 was planned to be performed between 02.04 (today) and the 20.04. This manipulation was not taken into account during the planning of the SCT in UJ33.

  • The maintenance caused the stop of the tests and was irreversible: it will be not possible recuperate the cooling power until the end of the intervention.

  • The tests has been rescheduled in agreement with TS-CV. The priority will be given to the work in SX2 (the primary circuit) in order that the water in UJ33 will be available the 16.04.
