• cooling circuits require 200-300 kW heat load in order not to freeze• circuits of the equipment must not be separated from the main cooling circuit • for the temperature surveillance (BE/OP/TI) alarms must be available

facility cooling circuit load (present or required)

Linacs and LEIR FDED-00049 enough heat load

PSB + TT2 FDED-00065 need to generate load

cooling circuits - IEFC 19/10/12

• CV will intensify the rounds during the closure especially if the weather is cold.

• On Monday January 7th , CV will restart :• PS : FDED-00032 PS Magnet• POPS: FTEB-00046

• POPS will be fully operational on Tuesday.

cooling circuits - IEFC 19/10/12

6. February 2012: a good example

• Extremely cold and windy weather • All the primary circuits were running with a reduced load. • Large amount of problems on drinkable and fire hydrant circuits but the

primary circuits had well resisted • POPS start up was delayed because the filling circuit was frozen →

corrective work acheived.

* EN/CV and EN/EL provide always piquet service

• ‘best effort’ service during working hours, but somebody must be reachable• piquets which are not required (magnets, kickers, LL RF, … do not appear)• magnets: in case of water leaks best effort

OP: TI plus support from beam operators plus supervisor
