The consequences of various postulated single failures during loss-of-fluid test (LOFT) Loss-of-Coolant Experiment (LOCE) L2-3 were analyzed for the LOCE L2-3 blowdown scoping experiment safety analysis (ESA). The following six of the LOCE L2-3 blowdown scoping ESA were performed: (1) Analysis A--failure of high-pressure injection system (HPIS) A; (2) Analysis B--failure of accumulator A; (3) Analysis C--failure of low-pressure injection system (LPIS) A, assuming accumulator A initial conditions of 550 psig and 84/sup 0/F; (4) Analysis CD--failure of LPIS A, assuming accumulator A initial conditions of 550 psig and 150/sup 0/F; (5) Analysis CE--failure of LPIS A, assuming accumulator A initial conditions of 650 psig and 150/sup 0/F; and (6) Analysis CF--failure of LPIS A, assuming accumulator A initial conditions of 650 psig and 115/sup 0/F. RELAP4/MOD5 models with conservative off-nominal initial conditions, and evaluation model (EM) options were used during the blowdown-refill phase of the analyses. RELAP4/MOD6 models with conservative input parameters and code options selected were used for the reflood phase of the analyses.
