3. DESCRIPTION OF TEST FACILITY

The LOFT Integral Test Facility is a scale model of a LPWR.  The intent of the facility is to model the nuclear, thermal-hydraulic phenomena which would take place in a LPWR during a LOCA.  The general philosophy in scaling coolant volumes and flow areas in LOFT was to use the ratio of the LOFT core [50 MW(t)] to a typical LPWR core [3000 MW(t)].  For some components, this factor is not applied; however, it is used as extensively as practical.  In general, components used in LOFT are similar in design to those of a LPWR.  Because of scaling and component design, the LOFT LOCA is expected to closely model a LPWR LOCA.

4. DESCRIPTION OF TEST

The fourth OECD LOFT experiment was conducted on 3 October 1983.  This was the first OECD LOFT large break experiment.  The initial and boundary conditions were chosen to be representative of USNRC licensing limits for commercial PWRs.  This included loss of off-site power coincident with LOCA initiation. This experiment included the first use in LOFT of pressurized fuel rods in the center bundle.  The experiment was initiated by opening the quick-opening blow-down valves in the broken hot and cold legs.
