In this nuclear power plant, steam is pumped at an average pressure of 5.45 MPa and an average temperature of 287oC. There are two steam generators, each with a capacity of 3312 tons/hr. The pipes used are outer diameter defined, 559 x 30.5 mm, 813 x 45 mm, 965 x 53 mm and 1067 x 54 mm. The main steam valve can close in 0.07 seconds and has a DN750 globe valve with a k factor of 3.8 based on the CRANE standard. Although the steam generators consist of a complex network of pipes, they can be modelled as two DN1000, 3.048 km long pipes.
