CSNI0013 LOFT/LP-FP-2.

1. NAME OR DESIGNATION:  LOFT/LP-FP-2.

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 eighth OECD LOFT experiment was conducted on 7 March 1985.  It was the second of the two experiments to be performed in the LOFT facility with intentional release of fission products.  Its principal objectives were to determine the fission product release from the fuel during a severe fuel damage scenario and the subsequent transport of these fission products in a predominantly vapor/aerosol environment.  This was the largest severe fuel damage experiment ever conducted, and serves as an important benchmark between smaller scale tests and the TMI-2 accident.

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.
