Abstract

SPES is an experimental facility which allows the assessment of thermalhydraulic codes through the simulation of a wide range of physical phenomena characterising different accident scenarios in PWRs. In 1999, in view of a possible proposal for an international cooperative programme, ENEA provided the SIET company with limited funding to restore the facility after five-year shutdown and ordered SIET a demonstration experiment where the new SPES configuration and the test conditions were selected to exploit in a valuable way the unique and outstanding characteristics of the facility. The test, defined by a working group composed of ENEA, ANPA, JRC Ispra, ANSALDO, Pisa University and SIET, consisted of a 10 equivalent break in Cold Leg, starting from full power and full pressure conditions. This document deals with the analysis of the comparison between calculated results and experimental data. Moreover, it underlines the SPES facility capability to simulate IB-LOCAs in addition to SB-LOCAs and other kind of transients which it was designed for.
