Considerations for the consolidation of BWR fuel

As a precursor to a possible rod consolidation demonstration program with BWR fuel, this study has reviewed the experience base relative to the consolidation of PWR fuel types. In addition, the quantities and types of spent BWR fuel in storage have been assessed. The mechanical design features of the various BWR fuel assemblies have been evaluated to identify special considerations/tooling/processes which may be required for the consolidation of BWR fuel. The experience base relative to reconstitution of BWR fuel has been reviewed with the General Electric Company, a supplier of BWR fuel reconstitution services, as it may relate to rod consolidation. Target performance objectives for systems designed to consolidate BWR fuel have been developed. These performance objectives establish targets or goals for fuel processing rates, fuel/NFBC compaction ratios, limits for personnel exposures and acceptable incremental impacts on normal plant operations which BWR rod consolidation systems would seek to achieve. 21 refs., 16 figs., 24 tabs
