Fuel element, for pressurized-water nuclear reactor, comprises plurality of fuel rods held in cells of distancing units whose inner zone has stiffening elements

摘要

The fuel element for a pressurized-water nuclear reactor comprises fuel rods held in cells of distancing units (4) whose inner zone (18) includes stiffening elements (20). This ensures that the distancing units are deformed only within areas beyond the inner zone when lateral forces acting on them exceed a specified limit.
