This report describes the verification o the RELAP5 code version modified for LBE and Lead cooling systems against the thermal-hydraulic data made available within the framework of MEGAPIE, an irradiation experiment performed at SINO proton accelerator of PSI (CH) on a LBE liquid target. The code has been firstly assessed on the preparatory T/H experiments (single-pin tests and MEGAPIE Integral Tests). This phase has allowed to implement a suitable correlation far !he simulation of the thermal exchange conditions in the prototypical LBE-oil Heat Exchanger of the MEGAPIE cooling loop. In a second phase the work has focused on the post-test analysis of selected data from the MEGAPIE irradiation operation including both steady state and transient conditions. The calculation results have showed the good capability of the code to simulate the thermal hydraulics of the cooling circuit.
