Experimental study of isolation condenser performances by PIPE-ONE apparatus

Description
The paper discussed an experiment performed in PIPER-ONE facility which simulates a General Electric BWR-6 with volume and height scaling ratios of 1/2200 and 1/1, respectively. The apparatus was properly modified to test the thermalhydraulic characteristics of an isolation condenser-type system. THis system consists in an once-through heat exchanger, immersed in a pool with water at ambient temperature and installed at about 10 m above the core. The analysis of a first test on isolation condenser behaviour, named PO-SD-8, performed in 1992 showed that the RELAP5 code predicts well the overall thermohydraulic behaviour, but discrepancies were identified in predicting local phenomena occurring in the pool and in the isolation condenser. Therefore a second test, (named PO-IC-2), has been performed with improved instrumentation. The paper describes the results obtained in test PO-IC-2 and discusses the capabilities of the Relap5/Mod3.1 code. (author). 22 refs, 10 figs, 4 tabs
