How to calculate the pin power distribution

Dear all,

I tried to calculate the beavrs reactor core consists of assembly and water gap between them. To be more clear, I drew the following diagram:

core with water gap745×460 7.82 KB

The gray assembly is consists of 17*17 pin cells and there is a water gap (blue) between the two assemblies. There is no integer proportional relationship between the width of water gap and the size of pin. Then, how can I calculate the pin power distribution? Is there and simple example?

Thank you.

Hi @wangyahui,

You can tally heating or heating-local with DistribcellFilter which can provide a separate score for a repeated pin cell in a geometry.

Thank you very much. I will try it.
