Abstract

The paper subject regards the validation of the RELAP5/Mod3.2.2B, the best estimate code modified to deal with fluids of interest for the XADS (eXperimental Accelerator Driven System), a Lead Bismuth Eutettic alloy (LBE) cooled ADS design set up at Ansaldo Industry. The validation will be made exploiting the experimental program carried out on support of XADS design and MEGAPIE experiment, at the ENEA Research Centre of Brasimone (Italy), making use of CHEOPE and CIRCE facilities. The comparison between experimental results and post test calculations allows the check ofthe code capability in simulating the 1Dym fluid-dynamic of heavy metals. In particular, CHEOPE tests have provided data far the validation of the new heat exchange correlations introduced in RELAP5 and the first experimental campaign on CIRCE facility allows the assessment of the code capability to simulate the LBE T/H both in single-phase and in two-phase flow conditions.
