In this paper, the possibility of using plate fuel elements in tight-lattice water reactors instead of rod fuel elements is explored. For this purpose we compared the thermal-hydraulic and neutronic aspects of plates with those of rod fuel elements. Because of the fact that plates have a higher mechanical strength than rods with equal dimensions, it is possible to reduce the thickness of the plates and thus reduce the centerline temperature. This fact and other thermal-hydraulic considerations demonstrate that plate fuel elements are safer than rods with respect to their resistance to LOCA. Preliminary neutronic calculations indicate that plates and rods have about the same neutronic characteristics.
