CATHARE code has been applied to Isolation Condenser experiment conducted in PIPER-ONE facility. PIPER-ONE simulates a General Electric BWR-6 with volume and height scaling ratios 1/2200 and 1/1, respectively. The integral test facility was properly modified to reproduce typical IC thermal-hydraulic conditions for the test PO-IC-02. The facility was equipped with an once-through heat exchanger immersed in a pool of ambient temperature water, installed roughly 10 m above the core, in aim to reproduce qualitatively the phenomenologies expected for Isolation Condenser in the Simplified BWR (SBWR). The facility is installed in Dipartimento di Costruzioni Meccaniche e Nucleari of Pisa University (I). CATHARE is a thermal-hydraulic computer code developed at the Centre d`Etudes Nucleaires de Grenoble (CENG) for the prediction of nuclear power plant behavior in case of transients. CATHARE2 V1.3E was applied during the activity. Experiment PO-IC-02 included two subsequent power levels with initial pressure of 5.1 MPa. The Isolation Condenser was active during the whole experiment except between the two different power levels. The aim of the calculation was to reproduce the experiment. This was not achieved. CATHARE2 V1.3E calculates too low heat transfer coefficients for condensation of steam.
