TL;DR Summary
PWR Core equilibrium cycle
Hey,
Any one in this forum experienced in utilizing Simulate3 to model 3 batches equilibrium cycle for PWR.
I prepared the casmo input files and prepared the initial cycle for the core , but i have trouble how to do the transition cycles in order to reach the equbilrium one.

Look at the example files included with the code. There is a PWR example problem that exactly does this.

Do you have an experience in simulate code, I started writing my own input but I'm not quit sure about it.

What documentation does one have?

Usually in a fresh core, there are three regions of different enrichments. After the first cycle, approximately one-third of the core is removed, the fuel to remain may be 'shuffled', and fresh fuel is added to the core.

Here are some notes from an MIT course for which they used CASMO4

for casmo input files i have no problem, but the simulate code it is little bit tricky
 

FAQ: Simulate3: Modeling 3-Batch Equilibrium Cycle for PWR

What is Simulate3 and its primary application?

Simulate3 is a sophisticated nuclear reactor core simulation software used to model and analyze the behavior of Pressurized Water Reactors (PWRs). Its primary application is to simulate the 3-batch equilibrium cycle for PWRs, allowing for detailed examination of reactor performance, fuel management, and safety analysis.

How does Simulate3 model the 3-batch equilibrium cycle for PWRs?

Simulate3 models the 3-batch equilibrium cycle by dividing the reactor core into three distinct batches of fuel, each at different stages of their life cycle. The software simulates the loading, operation, and unloading of these batches over multiple cycles to achieve a steady-state equilibrium condition, providing insights into the long-term behavior and performance of the reactor core.

What are the key inputs required for Simulate3 simulations?

The key inputs required for Simulate3 simulations include reactor core geometry, fuel assembly design, initial fuel compositions, control rod configurations, operational history, and thermal-hydraulic conditions. Accurate input data is crucial for reliable simulation results and effective analysis of the reactor's performance.

What outputs can be expected from a Simulate3 simulation?

Simulate3 provides a wide range of outputs, including power distribution, fuel burnup, isotopic compositions, reactivity coefficients, temperature distributions, and thermal-hydraulic parameters. These outputs help in evaluating the reactor's operational efficiency, safety margins, and fuel utilization over the simulated cycles.

How does Simulate3 ensure the accuracy and reliability of its simulations?

Simulate3 ensures accuracy and reliability through rigorous validation and verification processes. The software is benchmarked against experimental data and other established simulation tools. Additionally, it employs advanced numerical methods and algorithms to solve the complex equations governing reactor physics and thermal-hydraulics, ensuring high fidelity in its simulations.
