Hi everyone,
I’m currently working on a simulation of a prismatic-type High Temperature Gas-cooled Reactor (HTGR) using OpenMC. I’ve created a single fuel block, but I’m having trouble stacking the blocks axially to create a fuel column. Each fuel column of the reactor consists of 8 fuel blocks stacked on top of each other.
I’ve tried creating a fuel rod with the fuel column height, but there are too many TRISO particles in one rod, causing the simulation to fail due to high memory usage. Even using one-sixth of the core doesn’t solve the issue. So, I’m wondering if there is a way to repeat one fuel block to create the fuel column instead.
I would greatly appreciate any suggestions.
Thank you.
