Used Fuel Disposition Campaign Phase I Ring Compression Testing of High Burnup Cladding

The purpose of ring compression testing is to generate data to support the development of the technical basis for extended storage and transportation of high-burnup fuel.  This report highlights the results of completed Phase I testing of high-burnup M5® cladding and the revised three-year test plan.  The goal of the ring compression testing is to identify process conditions that would minimize radial-hydride formation and the corresponding DBTT of high-burnup fuel cladding and to generate data and models to support the development of the technical basis for extended storage and transportation of high-burnup fuel.
