• 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
