1 of 1 PRINCIPAL AUXILIARY SHIELDING Design parameters for the auxiliary shielding include:
Core thermal power 3391 MWt Fraction of fuel rods containing small clad defects 0.01 Reactor coolant liquid volume 12600 ft.3 1 Letdown flow (normal purification) 75 gpm Cesium purification flow (intermittent) 75 gpm Cut-in concentration deborating demineralizer 100 ppm Dose rate outside auxiliary building
<1 mrem/hr Dose rate in the building outside shield walls
<2.5 mrem/hr COMPONENT CONCRETE SHIELD THICKNESS Ft. - In.
Mixed Bed Demineralizers 4 - 0 Charging pumps 2 - 6 Liquid holdup tanks 2 - 8 Volume control tank 3 - 9 Reactor Coolant filter 2 - 6 Boric Acid Evaporator 2 - 4 Gas decay tanks 3 - 3 Waste Gas Compressors 2 - 8 Waste Evaporator 2 - 0 Liquid Waste Holdup Tank 2 - 0 Spent Resin Storage Tank 4 - 0 1 This value has been conservatively chosen for the purpose of shield design. Actual best-estimated reactor coolant systems volumes can be obtained from the current Westinghouse IMP databases.
