  Since November 2009, the LHC commissioning progresses very well, both with
proton and lead beams. It will continue in 2011 and nominal LHC operation is
expected to be attained in 2013. In parallel, plans for various LHC upgrades
are under discussion, suggesting a High-Luminosity (HL) upgrade first and a
High-Energy (HE) upgrade in a later state. Whereas the upgrade in luminosity
would require the modification of only some few key accelerator components like
the inner triplets, the upgrade in beam energy from 7 TeV to 16.5 TeV would
require the exchange of all dipoles and of numerous other accelerator
components. The paper gives an overview of the radiation protection issues
related to the dismantling of LHC components prior to the installation of the
HE-LHC components, i.e. after about 20 years of LHC operation. Two main topics
will be discussed: (i) the exposure of workers to ionizing radiation during the
dismantling of dipoles, inner triplets or collimators and experiments and (ii)
the production, conditioning, interim storage and final disposal of radioactive
waste.
