Simulate3: Modeling 3-Batch Equilibrium Cycle for PWR

Click For Summary

Discussion Overview

The discussion revolves around the use of Simulate3 for modeling a 3-batch equilibrium cycle in a Pressurized Water Reactor (PWR). Participants share their experiences and seek guidance on transitioning cycles to achieve equilibrium, as well as the associated input file preparations.

Discussion Character

  • Technical explanation
  • Debate/contested
  • Homework-related

Main Points Raised

  • One participant inquires about experiences with Simulate3 and expresses difficulty in transitioning cycles to reach equilibrium.
  • Another participant suggests looking at example files included with the code, noting that there is a specific PWR example that addresses the issue.
  • There are repeated requests for documentation related to Simulate3 and CASMO, with emphasis on the need for understanding the core's initial conditions and fuel management.
  • Participants discuss the typical structure of a fresh core, mentioning three regions of different enrichments and the process of removing a portion of the core after the first cycle.
  • One participant highlights the importance of developing CASMO lattice files through design or discharge burnup, referencing examples that may be available.
  • Concerns are raised about the complexity of the Simulate code, with one participant expressing confidence in CASMO input files but uncertainty regarding the Simulate code itself.

Areas of Agreement / Disagreement

Participants express varying levels of familiarity with Simulate3 and CASMO, and while some suggest resources and examples, there is no consensus on the best approach to transition cycles or on the adequacy of available documentation.

Contextual Notes

Participants mention the need for specific examples and documentation, indicating that there may be limitations in the resources available for understanding the transition cycles and the use of Simulate3.

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
