What is the benefit of the moisture separator in the power plant of Problem 4.121?

Problem 4.121

A somewhat simplified flow diagram for a nuclear power plant is given in Fig. P4.121. Mass flow rates and the various states in the cycle are shown in the accompanying table.

The cycle includes a number of heaters in which heat is transferred from steam, taken out of the turbine at some intermediate pressure, to liquid water pumped from the condenser on its way to the steam drum. The heat exchanger in the reactor supplies 157 MW, and it may be assumed that there is no heat transfer in the turbines.
a. Assuming the moisture separator has no heat transfer between the two turbine sections, determine the enthalpy and quality (h4, x4).

b. Determine the power output of the low-pressure turbine.

c. Determine the power output of the high-pressure turbine. d. Find the ratio of the total power output of the two turbines to the total power delivered by the reactor.
