Description
This talk aims to summarize the experience with the SPS and LEP over the past 15
years dealing with leaks in radioactive components and environments. The annual
doses and sources of radiation will be presented together with dose estimations
during a typical mechanical intervention during the run. The corrosion of the
stainless steel materials by the hydrochloric acid is the main cause of leaks
appearing in the radioactive environments of CERN machine. Example of how recent
problems have been handled will be presented as well as the strategy implemented in
collaboration with the Radioprotection Group to reduce the cumulated dose during a
given intervention by a proper optimization of the design. This strategy is already
used for the LHC machine.
