Pressure vessel
 scroll 
Thick-walled cylindrical steel vessel enclosing the
reactor core in a nuclear power plant. The vessel is made of a special
fine-grained steel well suited for welding and with a high toughness
while showing low porosity under neutron irradiation. The inside is
lined with austenitic cladding to protect against corrosion. For a 1,300
MWe pressurized water reactor, the pressure vessel is about 12 m high,
the inner diameter is 5 m, and the wall of the cylindrical shell is
about 250 mm thick. The overall weight amounts to approx. 530 t without
internals. The vessel is designed for a pressure of 17.5 MPa (175 bar)
and a temperature of 350 °C.
