Computational Analysis of TAPIRO Experiments by the SERPENT and ERANOS Codes

The TAPIRO experimental reactor is modelled by the Monte Carlo code SERPENT and the deterministic code ERANOS. The results of the simulations of some measurements performed on the reactor in the past are compared to the experimental data. The analysis of the results is focused on the role of cross section data libraries, on the approximation in the modelling associated to the use of deterministic tools and on the need of nuclear data, with special regards to copper, being a relevant component in the TAPIRO reactor.
