Thermodynamic analysis of a simplified PWR plant.

AI Thread Summary
The discussion focuses on solving thermodynamic problems related to a simplified Pressurized Water Reactor (PWR) plant. Participants are tasked with drawing a temperature-entropy diagram, computing the primary to secondary flow rate ratio, and determining both the nuclear plant thermodynamic efficiency and the cycle thermal efficiency, assuming isentropic efficiencies of 85% for the turbine and pump. A specific challenge highlighted is calculating the flow rate ratio while considering the impact of the primary pump on thermal efficiencies. The conversation emphasizes the importance of energy transfer between the primary and secondary systems, and participants reference the book "Nuclear Systems I - Thermal Hydraulic Fundamentals" by Todreas for further guidance. Overall, the thread aims to clarify the thermodynamic analysis of the PWR cycle.

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 .

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.
 
What is the name of the book?

Hello everyone, I am currently working on a burnup calculation for a fuel assembly with repeated geometric structures using MCNP6. I have defined two materials (Material 1 and Material 2) which are actually the same material but located in different positions. However, after running the calculation with the BURN card, I am encountering an issue where all burnup information(power fraction(Initial input is 1,but output file is 0), burnup, mass, etc.) for Material 2 is zero, while Material 1...
Hi everyone, I'm a complete beginner with MCNP and trying to learn how to perform burnup calculations. Right now, I'm feeling a bit lost and not sure where to start. I found the OECD-NEA Burnup Credit Calculational Criticality Benchmark (Phase I-B) and was wondering if anyone has worked through this specific benchmark using MCNP6? If so, would you be willing to share your MCNP input file for it? Seeing an actual working example would be incredibly helpful for my learning. I'd be really...
