Safety organisation of the LIU project In accordance with the Safety Regulation SR- SO, the Project Leader (PL) is responsible for Safety in the Project The PL is assisted by a Project Safety Officer (PSO) who oversees and coordinates Safety aspects of the Project: The PSO verifies that Safety aspects have been correctly considered within the different work packages, that the proposed Safety measures are consistent with the general Safety policy of the Project and that they are correctly applied by the different work packages, The PSO identifies the Safety issues arising at the interface between work packages and whenever required, asks the relevant work packages to apply the appropriate measures, The PSO coordinates the editorial work for the Safety documentation of the Project. The work package Holders are responsible for proposing and applying the correct Safety measures for the work and equipment included in their work package HSE produces the Launch Safety Agreements (LSA) for non radiological aspects that details the Safety requirements and delivers the safety clearances when applicable. The Radiation Protection Group takes responsibility for all radiation protection aspects. 17-19 October 2016 LIU / HL-LHC Cost and Schedule Review Safety : A. Funken, J. Vollaire, R. Froeschl, H.

Safety documentation of the LIU project As for all projects, a safety documentation (Safety File) is required to demonstrate that the new systems or facilities: Are being designed respecting safety principles and Can be constructed, commissioned, operated and dismantled safely It covers occupational health and safety, the protection of the environment and the safe operation of CERN’s Installations The LIU project is divided in Work Packages (WP), i.e equipment or services delivered by the different groups. Each WP has one WP Holder Due to the extend of the project that covers the upgrade of five different accelerators, the concept of Safety Package (SP) was introduced 17-19 October 2016 LIU / HL-LHC Cost and Schedule Review Safety : A.

RP documentation and RP studies RP work-packages within LIU (PSB, PS, SPS and LIU ions) RP performs studies and advises for upgrades with radiological implications (beam dumps, collimators, scrapers, energy increase, beam losses…) Studies documented in Technical Notes and are being summarized in RP Safety Files (stray radiation and shielding, residual dose rate, induced activity, air and cooling water activation, RP monitoring…) mSv/h Examples of studies (FLUKA code): SPS beam dump – Residual dose rate 1 week cooling time PS internal beam dump study (stray radiation with dump in SS75) PSB injection – Residual dose rate 17-19 October 2016 LIU / HL-LHC Cost and Schedule Review Safety : A.

Radiological impact of operation with LIU parameters Effects (from a RP standpoint) of beam energy and beam intensity increase have been assessed and mitigated when needed: New charge-exchange injection at 160 MeV in the PSB PSB extraction and PS injection at 2 GeV (instead of 1.4 GeV) Shielding re-enforced in LS1 above the injection and extraction areas of the PS (mandatory for long term PS operation) Detailed RP studies for new intercepting devices (design optimization: shielding and intervention scenario) PSB: Beam dump (installed in LS1), new PSB scrappers PS: Replacement of internal beam dumps in SS47/SS48 SPS: Unshielded beam dump (in LSS1) replaced by new one in LSS5 with appropriate shielding. Scrappers, TCDI collimators in transfer lines are also being studied. LIU ions: no impact on the radiological situation (Linac3, LEIR, PS and SPS) 17-19 October 2016 LIU / HL-LHC Cost and Schedule Review Safety : A. Funken, J. Vollaire, R. Froeschl, H. Vincke, L.

LIU Safety Packages A SP comprises a set of systems located in a same location under the responsibility of several groups. The LIU project includes 16 SPs (and 90 WPs). A Safety Package Coordinator (SPC) is appointed for each SP. The SPC is acting as the technical link person for the corresponding SP. A SP does not change the fact that each group remains owner and responsible of their own Work Package (WP), which are covering their equipment or services. The HSE Launch Safety Agreements (LSA) covering the conventional safety aspects are produced at the level of the SPs. 17-19 October 2016 LIU / HL-LHC Cost and Schedule Review Safety : A. Funken, J.
