  A central component of the European Spallation Source is the high-power
proton accelerator. The accelerator aims in the future to provide 2 GeV protons
to a rotating tungsten target for the production of neutrons at 5 MW of average
beam power for neutron scattering studies. Extensive shielding surrounds the
accelerator, in order to provide sufficient safety for the public and workers
against radiation produced along it's length. This largely comprises several
meters of soil, called the berm, and concrete structures located around the
accelerator tunnel. However, due to the need for access to the accelerator,
during maintenance and connections for other utilities, the shielding contains
a number of penetrations which leads to weaknesses in localized areas. For
these reasons, shielding design of such a facility must take care to address
issues related to both the deep-penetration of the radiation through thick
shields, while at the same time accounting for the streaming nature of the
radiation through ducts and chicanes. In addition, radiation produced from
activated components of the accelerator also poses risks for workers and
public. For example, activated magnets will need maintenance and workers may
need to access areas where activated water circulates. Thus, activation
analyses are also needed in combination with the prompt-dose rate estimates for
a complete analysis. In this summary, we present the results of a series of
such studies carried out on various components around the ESS accelerator.
