Fuel Handling and Storage Systems
Handling systems and storage facilities for nuclear fuel are provided in each unit Auxiliary
Building. The new fuel storage pit is designed to hold new fuel assemblies in a dry
condition. Storage racks hold the new fuel in place and ensure a safe configuration.
A water-filled pool constructed of concrete with interior stainless steel walls provides for the
storage of spent fuel assemblies. Stainless steel storage racks are designed to safely hold
up to 20 years of spent fuel generation plus space for a full core offload and a fresh batch of
fuel. A fuel transfer canal connects the spent fuel pool to the Containment Building for
refuelling operations.
A fuel transfer system is used to move fuel assemblies between the Auxiliary Building and
containment via the fuel transfer canal. A refuelling machine is used to insert and remove
fuel assemblies from the reactor, while a similar spent fuel handling machine is used to
move fuel assemblies within the spent fuel pool. A fuel elevator is used to lower new fuel
from the refuel floor into the spent fuel pool.
Plant Cooling Water Systems
Plant water systems include: the essential service water (ESW) system, the component
cooling water (CCW) system, the ultimate heat sink (UHS), the condensate storage and
transfer system, the turbine generator building closed cooling water system, the chilled water
(CW) system, and the makeup demineralizer system.
The ESW system utilizes water from the Arabian Gulf (the plant UHS) to remove heat from
plant SSCs. The ESW system consists of two safety-related divisions of two pumps and
three CCW heat exchangers capable of removal of 100 percent of the station safety-related
heat load. The four ESW pumps are provided with upstream traveling screens for debris
removal.
Other Auxiliary Systems
Plant process auxiliaries include a compressed air system for instrumentation and
equipment applications, systems for sampling liquids and gases, equipment and floor
drainage system, and chemical and volume control system (CVCS).
The CVCS maintains the chemistry and volume of reactor coolant system water, and is used
to adjust reactor coolant boron concentration for reactivity control.
Heating, ventilation, and air conditioning (HVAC) systems are provided for personnel comfort
and safety and for equipment protection. The control room, fuel handling area, and
emergency diesel generator rooms are among the areas whose HVAC systems are
designed as safety-related systems.
A plant fire protection system consisting of fire detection and alarm systems, fixed automatic
sprinklers, fire barriers, and stationed manual firefighting equipment is provided. Automatic
carbon dioxide systems are installed in the diesel generator and fuel tank rooms, and in the
cable spreading rooms.
Radioactive Waste Management System
Radioactive waste is managed through the liquid, gaseous, and solid waste management
systems housed in the Compound Building. The liquid waste management system,
consisting of storage tanks, filters, and pumps, is common to both reactor units. Liquid
waste is collected in segregated waste collection tanks, processed to reduce activity level,
