[en] This paper is an overview of the results for the last 12 months of Thermal Fuels Behavior Program (TFBP) research being conducted in the Power Burst Facility (PBF) at the Idaho National Engineering Laboratory. TFBP is an integral experimental and analytical program designed to provide information on the behavior of light water reactor fuels under normal, off-normal, and accident conditions. The PBF reactor core can be operated to provide test conditions typical of off-normal conditions such as loss-of-coolant accidents (LOCA), power-cooling-mismatch (PCM) accidents, reactivity initiated accidents (RIA), operational transients with or without scram (OPTRAN), and inlet flow blockages (IFB). During the last 12 months, fuel behavior testing in the PBF consisted of seven RIA tests and three LOCA tests. The RIA tests performed were the PBF Lead Rod Tests, the RIA Scoping Test Series, and Tests RIA 1-1 and RIA 1-2. The LOCA tests consisted of the PBF Loss-of-Fluid Test (LOFT) Lead Rod Test Series. In the future, the TFBP is scheduled to conduct a second 9-rod bundle PCM test (Test PCM-7), a combination RIA/PCM test (Test PR-1), four LOCA tests (Tests LOC-3, LOC-5, LOC-7, and LOC-8), the first 9-rod bundle RIA test with irradiated rods (Test RIA 1-4), a thermocouple effects test (Test TC-1), additional RIA bundle tests, and start an operational transient test series
