Abstract:
An improved, accident tolerant fuel for use in light water and heavy water reactors is described. The fuel includes a zirconium alloy cladding (12) having a chromium or chromium alloy coating (18) and an optional interlayer (20) of molybdenum, tantalum, tungsten, and niobium between the zirconium alloy cladding (12) and the coating (18), and fuel pellets (14) formed from U 3 Si 2 or UN and from 100 to 10000 ppm of a boron-containing integral fuel burnable absorber, such as UB 2 or ZrB 2 , either intermixed within the fuel pellet (14) or coated (22) over the surface of the fuel pellet (14).
