† The EPR layout offers exceptional and
unique resistance to external hazards,
especially earthquake and airplane crash.
• To withstand major earthquake, the entire
Nuclear Island stands on a single thick
reinforced concrete basemat. Building
height has been minimized and heavy
components and water tanks are located
at the lowest possible level.
• To withstand large airplane crash, the
Reactor Building, Spent Fuel Building
and two of the four Safeguard Buildings
are protected by an outer shell made
of reinforced concrete. The other
two Safeguard Buildings are protected
by a geographical separation. Similarly,
the Diesel generators are located
in two geographically separate buildings
to avoid common failures.
The outer shell (in blue in the image) protects the Reactor Building, the Spent Fuel Building
and two of the four Safeguard Buildings including the control room.
