Simulate3: Modeling 3-Batch Equilibrium Cycle for PWR

AI Thread Summary
Users are seeking guidance on using Simulate3 to model a three-batch equilibrium cycle for Pressurized Water Reactors (PWR). They have successfully prepared CASMO input files but are struggling with the transition cycles necessary to achieve equilibrium. The discussion highlights the importance of developing CASMO lattice files and refers to example problems included with the code for reference. Additionally, participants mention the need for documentation and share links to MIT course materials that may assist in understanding CASMO4. Overall, the conversation emphasizes the complexities of using Simulate3 and the need for shared experiences and resources.

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.

One has to develop the CASMO lattice files through the design or discharge burnup. There should be examples as rpp indicated.

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
 
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...
