Is there any code in openmc to validate any single assembly of a reactor core? If possible, give any code and relevant data or paper to validate a single assembly. Any kind of help would be really appreciated! Thank you! ---

There is no automated way of performing validation of specific models in OpenMC. The onus is really on you to come up with a fair point of comparison. Typically when people want to validate a specific model or configuration, they would perform either a comparison between two codes (e.g., two Monte Carlo codes, or a Monte Carlo code and a deterministic code), a comparison between simulation and experiment (if they are modeling an experiment), or if the model is really simple it may be possible to compare between simulation and theory (e.g., a simulation of a bare homogeneous slab).

Thank you so much!
