A 17×17 jacketless fuel assembly for a PWR-type light-water reactor uses thorium as the fuel. The fuel assembly has a square shape in the plan view, a seed region, a blanket region that encircles it, an upper nozzle, and a lower nozzle. The fuel elements of the seed region re arranged in the rows and columns of a square coordinate grid and have a four-lobed profile that forms spiral spacer ribs along the length of a fuel element. The blanket region contains a frame structure within which a bundle of fuel elements made from thorium with the addition of en...
1. A fuel assembly for a light-water nuclear reactor with a square shape in the plan view and comprising: a seed region, including a bundle of seed fuel elements that are arranged in the rows and columns of a square coordinate grid in a cross-section; wherein each seed fuel element has a four-lobed profile forming spiral ribs, and comprises a kernel that includes enriched uranium or plutonium; anda blanket region, surrounding the seed region and including a bundle of breeding fuel elements;wherein, when viewed in a plan-view cross-section, the breeding f...
