Comparison of HYDRA-II predictions to temperature data from consolidated and unconsolidated model spent fuel assemblies
Using the HYDRA-II computer code, Pacific Northwest Laboratory (PNL) researchers analyzed the thermal performance of two model spent fuel assemblies. The numerical simulations were based on information from offsite laboratory tests conducted previously on an unconsolidated and a consolidated rod assembly. The objectives of the PNL effort were to examine the thermal characteristics of the consolidated rod assembly and to validate the predictive capability of the HYDRA-II code for application to such analyses. When compared to the physical test data, the predictions generated by HYDRA-II were in excellent agreement for all temperature comparisons. These analyses provided further validation of HYDRA-II's capability to accurately predict thermal performance of spent fuel storage system components. Results obtained for the consolidated rod assembly lend strong support to the value of further investigations of this option for dry storage of spent fuel. 14 refs., 10 figs., 7 tabs.
