3. DESCRIPTION OF TEST FACILITY
BWR/6-218 standard plant. A full size bundle with electrically heated rods is used to simulate the reactor core. A scaling ratio of 1/624 is applied in the design of the system components. Key features of the FIST facility include: (1) Full height test vessel and internals; (2) correctly scaled fluid volume distribution; (3) simulation of ECCS, S/RV, and ADS; (4) level trip capability; (5) heated feedwater supply system, which provides the capability for steady state operation.

4. DESCRIPTION OF TEST
4DBA1 simulates conditions in the peak power bundle of BWR/4-218 after a double-ended large break in one of the recirculation suction lines. The BWR/4 break size is much larger than the corresponding BWR/6 break. The scaled break sizes are 1.05 sq.in. in the suction line and 0.1645 sq.in. at the drive line nozzle based on the single bundle FIST scaling. The initial power of 6.09 MW simulates a peak power bundle.
