Simulate3: Modeling 3-Batch Equilibrium Cycle for PWR

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

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
 

1. What is "Simulate3"?

"Simulate3" is a computer program developed for simulating and modeling the 3-batch equilibrium cycle for Pressurized Water Reactors (PWR). It is designed to assist scientists and engineers in analyzing and optimizing nuclear reactor designs.

2. What is a 3-batch equilibrium cycle?

A 3-batch equilibrium cycle refers to the process of refueling a nuclear reactor by replacing one-third of its fuel assemblies at a time. This cycle ensures that the reactor always has a balanced mix of fresh and spent fuel, maximizing its efficiency and reducing the production of radioactive waste.

3. How does "Simulate3" model the 3-batch equilibrium cycle for PWR?

"Simulate3" uses advanced mathematical and computational algorithms to simulate the behavior of a PWR and its fuel assemblies. It takes into account factors such as neutron flux, fuel depletion, and heat transfer to accurately model the performance of the reactor over multiple refueling cycles.

4. What are the benefits of using "Simulate3"?

"Simulate3" enables scientists and engineers to test and optimize different fuel assembly configurations and refueling schedules for PWRs. It also allows for the analysis of various scenarios, such as power ramping and load-following, to ensure safe and efficient operation of the reactor.

5. Is "Simulate3" widely used in the nuclear industry?

Yes, "Simulate3" is a widely recognized and trusted tool in the nuclear industry. It has been used by numerous nuclear power plants and research institutions around the world to improve the safety and performance of PWRs.
