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 second OECD LOFT experiment was conducted on 23 June 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 early pump trip. The experiment was conducted from initial temperature and pressure conditions representative of typical commercial PWRs. 5.
EXPERIMENTAL LIMITATIONS OR SHORTCOMINGS - Short core and steam generator, excessive core bypass, other scaling compromises, and lack of adequate measurements in certain areas. 6.
PHENOMENA TESTED - Phase separation, core heat transfer, ECC bypass and penetration, and quench front propagation. 7.
SPECIAL FEATURES OF EXPERIMENT - Only integral research facility with a nuclear core. 8.
COUNTERPART EXPERIMENTS - Semiscale. 9.
