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

This was the third of the NRC L9 series of experiments on Anticipated Transients with Multiple Failures. Loss-of-feedwater effects were studied. The experiment was conducted on 7 April 1982.
