Non-Deterministic Results and Fission Bank Warning

Hello everyone,

I am currently working on the NuScale-like core neutronic benchmark, and I’m facing a particular issue that I could use some assistance with. I keep getting this warning:

“WARNING: The shared fission bank is full. Additional fission sites created in this generation will not be banked. Results may be non-deterministic.”

The issue is, I’m getting different results with each run, which shouldn’t be the case. Could you please assist me in addressing this problem?

Thank you in advance for your help.
