[en] A steam generator system transient analysis package (MINET), recently incorporated into the SSC code (a nuclear power plant systems analysis code), is reported. Essentially a code within a larger code, MINET is so named because it is based on a momentum integral network method. Since the SSC code is being used extensively in the analysis of the Clinch River Breeder Reactor Plant (CRBRP), an analysis of the CRBRP steam generator system, using MINET, is reported. Plant transient data are generally unavailable for such advanced power plants, therefore, results from computer analysis of a CRBRP station blackout event, using the DEMO code, are shown. Comparable SSC/MINET analysis provided similar results, particularly when two specific DEMO assumptions were factored into the MINET calculations. A more extensive SSC/MINET analysis of a CRBRP station blackout event, with pony motors and auxiliary feedwater pumps unavailable, is also reported
