Buildingheight has been minimized and heavycomponents and water tanks are locatedat the lowest possible level.• To withstand large airplane crash, theReactor Building, Spent Fuel Buildingand two of the four Safeguard Buildingsare protected by an outer shell madeof reinforced concrete. The othertwo Safeguard Buildings are protectedby a geographical separation. Similarly,the Diesel generators are locatedin two geographically separate buildingsto avoid common failures.The outer shell (in blue in the image) protects the Reactor Building, the Spent Fuel Buildingand two of the four Safeguard Buildings including the control room.† The EPR Nuclear Island design has undisputed advantages for operators,especially where radiation protection and ease of maintenance are concerned.• The layout is optimized and based on the strict separation of redundant systems.• The distinction between access-controlled areas containing radioactiveequipment and non-controlled areas significantly contributes to reduceexposure of the operating personnel.• Maintenance requirements were systematically taken into account at the earlieststage of the design. For example, large setdown areas have been designed tomake maintenance operations easier for operating personnel.12 II 13
