Several FIST tests were simulated using the TRAC-BD1/MOD1 code at Brookhaven National Laboratory. The FIST (Full Integral Simulation Test) program is a joint project of the NRC, Electric Power Research Institute and General Electric. It was built to investigate small break LOCA and operational transients in BWRs and to complement earlier large break LOCA test results from TLTA (Two-Loop Test Apparatus). The facility is a BWR integral test facility with a full BWR height but volume scaled to 1/624 to the BWR/6 vessel. It has all the prototypical components of a BWR/6 but contains a single electrically heated full-size BWR fuel bundle. The flow areas and fluid volumes in all regions are closely scaled to 1/624. However, because of scaling difficulty, the test facility has a cylindrical external downcomer connected to the main vessel. The FIST tests consist of two phases (Phase I and Phase II) and the Phase I consists of ten tests. Among these, four tests were selected to be simulated in this study. They were: a BWR/4 MSIV closure ATWS (Test 4PMC1), a BWR/6 small break LOCA without HPCS (6SB2C), a BWR/6 large break LOCA (6DBAlB), and a BWR/6 main steam line break test (6MSB1).
