Pipe works in the UX85 experimental cavern

Activities related to WORK LOT 1- fixation of the supports for 16 transfer lines (OT included) along the

RB84 side and on top of the vault TX84- installation of the OT transfer lines in stainless steel (multilayer

pipes use to be quoted as an option)- installation of the supply/return OT distribution manifolds

Activities related to WORK LOT 4- installation of pipelines for chilled and mixed water (RB86), demineralised water (RB84), compressed air (both sides) networks, including supports and required equipments

Due to INTEGRATION matters

the detailed activities shall be scheduled and performed during:

JUNE – JULY 2005

Paolo Guglielmini TS / CV / DC 08th April 2005

Integration in the SCADA local supervision

IT 3307 – Paragraph 4.2.2.1 “Communication”Four additional cooling systems will also be locally supervised and operated from the

SCADA local supervision platform. These cooling systems are controlled by 3 PLCs, which are also built on Schneider Premium TSX equipment.

These PLCs are not included in the scope of the supply of this Technical Specification. 1 PLC Inner Tracker - Tracker Trigger1 PLC RICH 1 & 21 PLC VELO

The Contractor shall integrate in the SCADA local supervision platform database the process data from these 3 external PLCs.

The Contractor shall develop, test, install and validate on-site the local supervision means corresponding to these external cooling stations...

Provided commissioning of the cooling systems whose PLCs shall be integrated:

end of FEBRUARY 2006
