  12. 12. NUCLEAR POWER PLANTS FEATURES OF APR 1400 REACTOR VESSEL The Reactor Vessel is designed to withstand high pressure and temperature and contains nuclear internals and fuel. The Closure Head is removable to reload the fuel, while the Reactor Vessel is fabricated from ring-forged shells. To enhance safety, APR1400 adopts 4 DVI Nozzles, which inject the coolant water of SIT(Safety Injection Tank) into the core directly. Features ■241 Fuel Assemblies ■101 CEDM Nozzels ■93 CEDM ■2 Heated Junction Thermo Couples (HJTC) ■61 Fixed ICI Nozzles ■6 Surveillance Capsule Holders
  13. 13. DOOSAN HEAVY INDUSTRIES & CONSTRUCTION Forged Shell Manufacturing The major part of Reactor Vessel is fabricated from forged material. These ring-forged shells eliminate the need for longitudinal seam welds thereby reducing production and inspection time. Material of the Reactor Vessel are carefully selected to withstand high pressure, temperature, and radiation. Shell & Nozzle, Bottom Head Welding The Reactor Vessel is composed of shells, nozzles and domes. The shells are first welded together. Then holes are machined to the shell for the assembly of nozzles. Finally, the shell and bottom head dome are welded to form the complete assembly. Closure Head Assembly The Reactor Vessel can sustain pressure by tensioning of studs at closure head. At the Closure Head, 108 nozzles are installed for the connection with CEDMs. The Closure Head Assembly and the Vessel are sealed by 54 Studs and 2 O-Rings. The Pad & Lug welded over the Closure Head surface are installed for supporting the IHA. 13
  14. 14. NUCLEAR POWER PLANTS FEATURES OF APR 1400 STEAM GENERATOR The Steam Generator is a type of heat exchanger which provides steam to drive the turbine generator. While heat is exchanged from the Primary Coolant Loop to the Secondary Coolant Loop within the Steam Generator, the coolant within each loop is isolated from the other. Features ■ 2000 MW Net Thermal Output per SG ■ Evaporator with Integral Economizer ■ Enhanced the reliability to F.I.V. (Flow Induced Vibration) of the tube bundle ■ Venturi Type Steam Outlet Nozzle with the flow restrictor function ■ Double Feed Line ■ Double Steam Line ■ High Capacity Separators ■ High Efficiency Dryers ■ Alloy 690 Thermal Treated Tubing ■ 409 Stainless Steel Tube Supports ■ Flow Distribution Plate ■ Eggcrate Flow Distribution Plate ■ High Capacity Blowdown ■ Improved Bend Region Tube Supports ■ Improved Feedwater Distribution System ■ Integral Retention Ring for Single Nozzle Dam ■ Permanently Marked Tubesheet Hole
  15. 15. DOOSAN HEAVY INDUSTRIES & CONSTRUCTION Material The Steam Generator is fabricated from ring forged shells and from close die forged heads. These forged Forgings eliminate the need for longitudinal and girth seam welds Thereby reducing production and Inspection time. Materials of Steam Generator are carefully selected to Withstand high pressure, temperature, And radiation. Tube Sheet Drilling The tubesheet has drilled holes for Installation of U-bend tube using 3-spindle deep hole drilling machine. Tube Installation The U-bend tubes are installed, then carefully expanded the thickness of the tubesheet. The expansion process shall be carefully controlled so as to produce as low as residual stress in the tubes as is reasonably achievable. 15
  16. 16. NUCLEAR POWER PLANTS EQUIPMENT MANUFACTURING AP1000 REACTOR VESSEL TM AP1000TM Reactor Vessel is designed with no bottom head penetrations to enhance safety and simplify manufacturing. The reactor vessel head employs a one piece forging which eliminates weld inspections and contributes ALARA targets. Shell Forging Cladding J-Groove Hole Machining
  17. 17. DOOSAN HEAVY INDUSTRIES & CONSTRUCTION EQUIPMENT MANUFACTURING AP1000 STEAM GENERATOR TM AP1000TM steam generator has high level reliability and enhanced performance by application of high performance primary and secondary moisture separators, advanced anti-vibration bars for upper tube support, broached plate for lateral tube support. Integral forgings are applied for Channel Head, Elliptical Upper Head and Transition Cone Shell. BTSP Machining Hydraulic Expansion AVB Installation 17
  18. 18. NUCLEAR POWER PLANTS EQUIPMENT MANUFACTURING PRESSURIZED HEAVY WATER REACTOR Doosan also supplied the major components of the PHWR (Pressurized Heavy Water Reactor) plants at Wolsong units 2,3 & 4 and Qinshan CANDU units 1 & 2 in China. PHWR uses natural uranium which is simpler to handle and easier to process into fuel assemblies than enriched uranium. Instead of H2O, which is used in a PWR, a PHWR uses heavy water (D2O) as the moderator and coolant. The system can be refueled during full-power operation. Doosan successfully supplied the Calandrias, Feeder/Headers and Steam Generators to Wolsong units 2,3 & 4. The Feeder/Headers and Steam Generators for use in Qinshan CANDU units 1 & 2 in China were also supplied. Steam Generator (PWHR) Feeder Header Assembly Four(4) Steam Generator is installed in the The Feeder consists of several hundred RCS (Reactor Coolant System) of PHWR pipes which transmit heated heavy water plant. from Caladria to Steam Generator. The Header merges and distributes the coolant
  19. 19. DOOSAN HEAVY INDUSTRIES & CONSTRUCTION EQUIPMENT MANUFACTURING CASK Doosan is one of the best Cask Manufacturing Companies in the world, especially, the only one in Korea. Doosan entered into Cask business in 1990 and delivered 2 sets of Cask for Kori Nuclear Power Plant in 2002 and 1 set of Cask for YGN Unit 2 Closure Lid and 2 sets of Cask fo UCN Units 1 & 2 in 2007.
