In a particular nuclear power plant the reactor is used to heat water to a saturated vapor at 700 psi , this vapor is then fed to another heat exchanger (superheater) that burns coal where it is superheated to 1100F. The steam then goes to a turbine after which some steam is extracted at 60 psi to a open feed water heater and the rest goes on to the second lower pressure stage of the turbine. The isentropic efficiency of the turbine is 87% and the condenser pressure is 1 psi. Determine the heat transfer in the reactor and in the super heater to produce a net power output of 1000 Btu.
