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.

6. PHENOMENA TESTED

Channel and bypass axial flow and void distribution; core heat transfer including DNB, dryout, RNB, surface to surface radiation; quench front propagation for both fuel rods and channel walls; separator behaviour including flooding, steam penetration and carryover; phase separation and mixture level
behaviour; guide tube and lower plenum flashing; natural circulation in core and downcomer; mixture level in core.
