CERN EN-CV Consolidation Efforts

The state of CERN’s technical infrastructure for cooling and ventilation presents a mixed picture, due to the progressive and continuous development of the Organization’s scientific facilities over the past 60 years. Several EN-CV installations, among them critical ones that are essential for the operation of the accelerator chain, have been in service for more than 30 years and their consolidation and upgrade are overdue. This paper describes methodology, scope and timeframe of the progressive and substantial consolidation program managed by EN-CV to improve the state of the installations under the group’s responsibility. Reliability and serviceability objectives are under-pinned by safety (radiation, fire and electrical), energy efficiency and various other safety and environmental aspects that are equally prioritised for these activities. Considering that a consolidated infrastructure shall be upgraded with additional functionalities to fulfil in-creased user requirements, EN-CV consolidations are significantly more than refurbishments and are essential to ensure reliable, safe, and sustainable operation of CERN’s scientific facilities while managing existing infrastructure dependencies.
