The nominal UO 2 fuel centerline temperature at full power is 4140°F. The water
exits the reactor vessel ( 615°F) at the top and flows through hot leg piping into
steam generators. The primary water enters the steam generator at the inlet plenum
and flows through the steam generator tubing. The total water flow rate through the
6
core in a typical 1150 MWe plant is approximately 138 10 lbm/h. The average
core coolant velocity is 15.5ft./s.
The 1150 MWe Westinghouse PWR has four U-tube steam generators (UTSGs).
Sections 10.6 and 12.5.1 provide details of UTSG characteristics.
