Abstract
Means are provided to minimize crud buildup at the interface between the tie plate and end plug in a nuclear fuel bundle. The means may comprise serrations in the end plug and/or serrations in the surface of the tie plate which serrations provide a flow of coolant through the end plug receptacles. A bleed hole extending into the interior of the tie plate may be provided to provide coolant circulation through any blind holes that may be in a tie plate.
