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. materials 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.

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.
