TRANSCRIPT

  • Slide 1
  • EXPERIMENTAL CLASS 5 STEAM GENERATOR 2015.05.15
  • Slide 2
  • EXPERIMENT 5. STEAM GENERATOR PWR system configuration and S/G S/G : Steam Generator Cross point between 1 st and 2 nd sides of the NPP Delivers heat Primary Barrier for safety Height : 21m Weight : 800t Reactor heat S/G heat Turbine
  • Slide 3
  • Primary water Secondary water S/G consists of; U-tubes Moisture Separator (Steam Dryer) water EXPERIMENT 5. STEAM GENERATOR
  • Slide 4
  • U-tubes isolate primary loop from the secondary loop If leak of the tubes -> Shut-down Prevention of Radioactive primary water release Degradation : Strict inspection & Repair process For Corrosion Problem Water Chemistry strictly monitored Chemical Treatment Tube Material Changes : Inconel 600 ->690 EXPERIMENT 5. STEAM GENERATOR
  • Slide 5
  • Moisture separators comprises of two principles : Centrifugal Force Pocket EXPERIMENT 5. STEAM GENERATOR
  • Slide 6
  • EXPERIMENTAL CLASS 6 PUMP 2015.05.15
  • Slide 7
  • Pump Type Rotor-dynamic pump Positive displacement pump Rotary Pump Reciprocating Pump Cavitation Reactor Coolant Pump EXPERIMENT 6. PUMP
  • Slide 8
  • Rotor-dynamic Pump Centrifugal( Volute ) pump Uses Rotational centrifugal force Axial Flow Pump converts kinetic Energy into Pressure EXPERIMENT 6. PUMP
  • Slide 9
  • Positive Displacement Pump Using mechanical force to generate pressure head Rotary Pump (Robe type, Vane Type) Reciprocating Pump : Pistons movement in the cylinder EXPERIMENT 6. PUMP
  • Slide 10
  • ROTORDYNAMIC PUMP VS POSITIVE DISPLACEMENT PUMP 10 Characteristic curve of Rotor-dynamic pump Characteristic curve of Positive Displacement pump
  • Slide 11
  • Rotor-dynamic pump VS Positive displacement pump
  • Slide 12
  • CAVITATION-VAPOROUS (H2O) 12
  • Slide 13
  • CAVITATION-GASEOUS(AIR) 13
  • Slide 14
  • CAVITATION 14
  • Slide 15
  • REACTOR COOLANT PUMP 15
  • Slide 16
  • ASSIGNMENT 16 Exp. 5: S/G - write down in your own words within 1 page Find types of SG degradation and suggest solutions with your point of view in 1 page Exp.6: Pump - write down in your own words within 1 page Explain why 1) pumps follow an isentropic line theoretically, 2) pumps deviate from the isentropic line in real applications Explain where rotor-dynamic pumps and positive displacement pumps are applied in NPP. Add reasons. Give some measures to avoid cavitation.
