Loss of Feedwater Heating

Feedwater temperature is reduced by 70°C according to the following sequence. In PCTRAN run the SGEC was set to control the turbine header pressure at 6.8 MPa and turn off the PHRS at about 1200 sec. So there are some fluctuations in pressure and temperature transients.  In general they are in good agreement with the PSAR.
