3. DESCRIPTION OF PROGRAM OR FUNCTION
This database contains axial burnup distributions for pressurised water reactors. The data were obtained directly from utilities whose reactors represent the range of commercial PWR fuel lattices. Data used comprise the name of the utility, the plant name, the vendor, fuel assembly lattice size, fuel vendor, fuel initial enrichment, initial Uranium mass, a serial number used to uniquely identify the profile and assembly attributes.
The data cover a range of burnup from slightly over 3 GWd/MTU to 55.3 GWd/MTU and an enrichment range of 1.24 w/o to 4.75 w/o U-235. Fuel designs contain different poison absorbers such as borosilicate glass, B4C, Integral Fuel Burnable Absorber (IFBA), Erbium and Gadolinium.
The database consists of 3169 computed axial burnup profiles, covering 106 cycles of operation. 1334 concern profiles of B&W 15x15 fuel design, 544 concern CE 14x14 fuel design, 228 concern CE 16x16 fuel design, 156 concern Westinghouse 15x15 fuel design and 907 concern 17x17 fuel design.
