Argonne describes plan for tests onhigh burnuo spent fuel

摘要

Argonne National Laboratory last month outlined the tests it designed to obtain the data NRC has requested on the axial tensile properties and impact resistance of zircaloy, Zirlo, and M5 cladding alloys on high burnup spent fuel. The tests are expected to provide the basis for assessing the claddings' performance during post-storage transportation accidents, according to a November 26 test plan that was released earlier this month on NRC's Adams database. The data generated by the tests are "intended to be used, along with appropriate modeling codes, for assessing whether or not cladding is likely to fail in transport, to assess the failure mode, and to assess the axial extent of failure along fuel rods," Argonne said in the plan.
