Principle of Steam Generation

• BWR
• Direct Cycle
• RPV Pressure 7 MPa
• RPV Temperature 288 oC
• Steam Generated in RPV (with Separator Dryer)
• Bulk Boiling in RPV
• 24 month cycles

• PWR
• Indirect Cycle
• RPV Pressure 15 MPa
• RPV Temperature 326 oC
• Steam Generated in Steam Generator (via Second
  Loop)
• No Bulk Boiling in RPV
• 18 month cycles

BWR Has Lower RPV Pressure and Simplified Steam
Cycle

Natural Circulation
Simplification without performance loss

• Passive safety/natural circulation
• Increase volume of water in Reactor Pressure
  Vessel (RPV)
• Increase driving head
• Chimney, taller vessel
• Reduce flow restrictions
• Shorter core
• Open downcomer
• Significant reduction in components
• Pumps, motors, controls, HXs
• Power Changes with Control Rod Drives
• Minimal impact on maintenance

Enrichment evolution
Gaseous Diffusion
Centrifuge
Laser Separation

• Gaseous uranium hexafluoride
• Semi-permeable membranes
• Separation between the molecules containing 235U
  and 238U
• Being replaced

• Rotating cylinders in parallel formations
• Centrifugal force forces heavier 238U gas towards
  outside and lighter 235U to center
• Requires less energy
• Primary source of enriched uranium today

• Lasers set at specific frequency selectively
  excite U235 for extraction
• Diverse process for secure supply
• Next generation technology
