EN-ACE YETS preparation Anticipation of works before the Long Shutdown 2 (LS2) during the (E)YETS. (Co-activities with the de- cabling campaigns to be carefully identified). The connection of the Linac4 to the PS Booster is foreseen for the LS2 but all equipment needs to be ready by the end of 2016 in case of an early full connection. De-cabling project: Completion of the identification/labelling of obsolete cables and disconnection of communication system cables.

EN-ACE YETS preparation PSB YETS motivation & objectives: PSB preventative and corrective maintenance programs. Consolidation and upgrade programs. PSB cable identification/disconnection project. Advance wherever possible LIU related projects Optimise machine performance (HWT’s).

This work is scheduled for the YETS 2015-2016 (and not later) because of schedule reasons: The power converters need to be ready for installation by the end of 2016 (deadline for the work linked to the connection of the Linac4 to the PSB) This work is not compatible with the de-cabling campaign foreseen during the EYETS 2016- 2017 The civil engineering and infrastructure works have been scheduled for the YETS 2015-2016 COMPLETED Courtesy J.

HSE-RP PSB YETS Feedback. Generally: Sorting and conditioning of radioactive waste still needs to be improved – reminder; slides below. ALARA principles now engraved into CERN culture and well respected! Estimated dose rates rarely exceeded. Dosimetry on 10/02/2016 3.2 man.mSv (PSB) Operational dosimetry: Still no verification at the entrance of Controlled Limited-stay and High Radiation areas, even no comparison a posteriori made available from BE/ICS, this is of the utmost importance for the next technical stop, we need support to get this topic moving forward… Intrusions into Controlled Limited-stay and High Radiation Areas: regular unmonitored and unreported occurrences (limited feedback, no post analysis for dose estimates etc.. ) EDMS 1560761 Courtesy G. Dumont

HSE-RP PSB YETS Feedback. EN-HE: cranes Increase the length of the remote control cables. Improve reliability to avoid being blocked above High Radiation Areas (for example during the coupling of the BHZ62): action: EN RSO informed. SMB/SIS: cleaning Improvements to the organisation, planning and CERN follow-up of the contractor (ex. PSB cleaning performed at the last minute and then out-of- working hours due to the organisational issues) Further training required to personnel working in Radiation Areas – (Suggest employing a dedicated cleaning company who are specialized in working in Radiation Areas?) Suitable and enough tooling required (water vacuum cleaners, autolaveuse, more powerful vacuum cleaners): action: SMB RSO informed. EN-CV: Redundant water pipe removal project. Well executed and optimised intervention. Remaining pipes inside the ring still need to be removed during the EYETS. Courtesy G. Dumont
