Benchmarking of the WIMSD/CITATION deterministic code system for the neutronic calculations of TRIGA Mark-III research reactors

•Benchmark study performed for the neutronic calculations of TRIGA research reactors.•WIMSD-5B/CITATION is the utilized code system along with the WIMSD-IAEA-69 library.•The studied condensed spectra are five and seven energy groups spectra.•Analyzed: lattice parameters, reactivities, CR worth, flux and power distribution.•The lattice and neutronic parameters showed the accuracy of both condensed spectra.
