TL;DR
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
