[en] Recorded test data are presented for Tests LOC-11B and 11C of the Thermal Fuels Behavior Program Loss-of-Coolant Accident Test Series. These tests, the first in a series of LOCA experiments conducted at the Power Burst Facility, investigated the behavior of the cladding of nuclear fuel rods exposed to temperatures similar to those expected in a pressurized water reactor during the blowdown and heatup phases of a 200% double-ended cold leg break. Tests LOC-11B and 11C were conducted at axial peak powers of 46 and 68 kW/m, respectively, which resulted in respective peak cladding temperatures of 880 K and 1030 K
