Component Function

127

Fuel Transfer Tube Isolation Valve

Together with a flange on the Containment side isolates Fuel Building from Containment when fuel transfers are not occurring

128

Fuel Transfer Tube

Used to transfer fuel between Fuel Building and Containment

129

Fuel Transfer Canal

Area where the transfer conveyor is located that is used to route the fuel assembly to the containment or receive the spent fuel assembly from containment.

130

Spent Fuel Storage Racks

Stainless steel racks with borated poly (or similar material) used to store each spent fuel assembly). Racks are about 16 feet high.

131

Spent Fuel Pool Bridge Crane

Crane used to move new and spent fuel assemblies

132

Spent Fuel Pool

A 40 foot deep pool that contains the storage racks for the spent fuel assemblies

133

Fuel Building Cask Loading Crane

A crane used for moving spent fuel into the stroage cask. For some plants this is the same as the spent fuel bridge crane.

134

Fuel Building Cask Handling Crane

A crane, typically rated at over 100 tons. This crane is designed so that no single failure can result in dropping the cask.

135

New Fuel Shipping Container Laydown Area

An area where new fuel is stored until the 2 assembly casks can be unloaded.

136

Cask Loading Pool

This is the small pool used for filling the cask with spent fuel.

137

Cask Washdown Pit

An area used for decontaminating the outside of the storage cask before is is moved to a rail car for transporting to an offsite facility or onsite via a transporter.

138

Sump Pumps

These are small pumps that take a suction from the sump supplied by drains from the cask washdown pit

139

Fuel Pool Cooling Heat Exchangers

These redundant heat exchangers remove heat from fluid circulated from the spent fuel pool. The heat is directed to the component cooling system.

140

Fuel pool Cooling Pumps

These redundant pumps circulate water from the spent fuel pool to the heat exchangers then back to the spent fuel pool.
