Abstract
A fuel assembly of a pressurized water nuclear reactor includes at least two fuel rods, respectively, having a cladding tube of given outer and inner diameters and pellets of given outer diameter received in the cladding tube, the fuel rods being disposed in the fuel assembly at a given mutual spacing of center points thereof, a ratio of the given mutual spacing of the center points of the fuel rods to the outer diameter of the cladding tube being in a range between 1.35 and 1.37.

In a pressurized water nuclear reactor, a fuel assembly having at least two adjacent fuel rods, at least one of said fuel rods comprising a cladding tube of given outer and inner diameters and pellets of given outer diameter received in said cladding tube, the fuel rods being disposed in the fuel assembly at a given mutual spacing of center points thereof, a ratio of said given mutual spacing of said center points of the fuel rods to said outer diameter of said cladding tube being in a range between 1.35 and 1.37.
In a pressurized-water nuclear reactor, a fuel rod comprising a cladding tube and pellets received in said cladding tube, said cladding tube having an outer diameter of 9.36 mm, and an inner diameter of 8.22 mm.
In a pressurized-water nuclear reactor, a fuel rod comprising a cladding tube and pellets received in said cladding tube, the cladding tube having an outer diameter of 10.53 mm, and an inner diameter of 9.30 mm.
