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


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.

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


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.

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.

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


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.
