LOFT results demonstrate resistance of unpressurized PWR fuel to loss-of-coolant accidents
The initial visual examination of LOFT unpressurized fuel and evaluation of data recorded during the first three LOFT large-break, loss-of-coolant experiments (LOCE's) indicated the LOFT fuel to be in a reusable condition. Since the September 1977 core load, the LOFT fuel assemblies have been exposed to three large-break loss-of-coolant experiments; LOCE L1-5 without nuclear heat and LOSE's L2-2 and L2-3 with a 26 and 39 kw/m peak fuel rod linear heat generation rate at test initiation. The LOFT power operation has resulted in a cumulative fuel burnup of 987 megawatt-days per metric ton of uranium and linear heat generation levels of up to 53 kw/m at the peak power location.
