DIONISIO 2.0: New version of the code for simulating a whole nuclear fuel rod under extended irradiation

With these improvements, the code results are compared with some 33 experiments compiled in the IFPE data base, that cover more than 380 fuel rods irradiated up to average burnup levels of 40-60 MWd/kgU. The results of these comparisons, which are presented here, reveal the good quality of the simulations.
