4. 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.

5. 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

12. 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

13. 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)

15. Radioactive waste
A budget of about 5 MCHF per year is allocated to the management of CERN’s radioactive waste
The forecast of all radioactive waste that will be produced until 2034 is available, based on information provided by the CERN groups and experiments (data collection as of December 2015 – Regularly updated)
The elimination of radioactive waste is planned such to allow the reception and temporary storage of the forecasted waste produced until the end of LS2 (Goal: elimination of about 3700 m3)
Period January - September 2016: for the first time, the amount of eliminated waste (1050 m3) exceeded the volume received (571 m3)

The current radioactive waste forecast is not listed per project but per group or experiment
An update identifying the radioactive waste linked to LIU and HL-LHC projects is ongoing and will be available at the beginning of 2017

20. 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.
