Used Nuclear Fuel Loading and Structural Performance Under Normal Conditions of Transport - Modeling, Simulation and Experimental Integration RD&D Plan

Used nuclear fuel (UNF) must maintain its integrity during the storage period in such a way that it can withstand the physical forces of handling and transportation associated with restaging the fuel and transporting it to treatment or recycling facilities, or to a geologic repository. This RD&D plan describes a methodology, including development and use of analytical models, to evaluate loading and associated mechanical responses of UNF rods and key structural components. The plan objective is to describe methods to be used in development of a preliminary assessment of the performance characteristics of UNF cladding and ancillary components under rail-related NCT loading, and effects on subsequent geometry, criticality, and retrievability .
