Thermodynamic analysis of a simplified PWR plant.

[marlh]

Can you help me solution:
The PWR plant of Figure 6-6 operates under the conditions given in Table 6-6. Assume that the turbine and pump have isentropic effciencies of 85%.
1. Draw the temperature-entropy (T-s) diagram for this cycle .
2. Compute the ratio ,of the primary to secondary fow rates.
3. Compute the nuclear plant thermodynamic efciency.
4. Compute the cycle thermal efciency .

Figure 6-6:

You should post this in the homework help section, and you need to start by showing your work, what you have attempted so far, and what you are having trouble with.

Thank QuantumPion comments! I think it is one of the problems of a nuclear engineer working with thermodynamics. My problem is "Compute the ratio ,of the primary to secondary fow rates" with pump of the primary. How change the cycle thermal efciency and the nuclear plant thermodynamic efciency when have this pump and haven't this pump.

Whatever energy leaves the primary system must go to the secondary system.

The changes in specific enthalpies of the primary and secondary coolants do not have to be the same.
