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 third OECD LOFT experiment was conducted on 14 July 1983.  It simulated a 3-in (7.62 cm) equivalent break diameter located in the hot leg of the operating loop.  The major objective of this experiment was to determine system transient characteristics for small hot leg break loss-of-coolant accidents with delayed pump trip.  The experiment was conducted from initial temperature and pressure conditions representative of typical commercial PWRs.
