Characterization of spent fuel approved testing material: ATM-106

Abstract

Printed in the UnitedGJ/kgM(28 MWd/kgM) and expected fission gas release of about i%. Characterizationdata includeI) descriptionsof as-fabricatedfuel design, irradiation history, and subsequentstorage and handling;2) isotopicgamma scans;3) fission gas analyses;4) ceramographyof the fuel and metallographyof the clac_ding; 5) special fuel studies involvinganalyticaltransmissionelectron microscopy (AEM); 6) calculatednuclide inventoriesand radioactivitiesin th,afuel and cladding;and 7) radiochemicalanalyses of the fuel and cladd"Jng. Additionalanalysesof the fuel are being conducted and will be _,ncluded in planned revisionsof this report.iii ACKNOWLEDGMENTS

SCALE 5.1 Predictions of PWR Spent Nuclear Fuel Isotopic Compositions

“…32 The fuel rod was located in a perturbed region at the edge of the center guide tube of the assembly. Rod NBD107 had a relatively high burnup for the enrichment.…”

“…The samples are identified in this report as MKP109-LL, MKP109-CC, and MKP109-P. The measurements in the ATM-106 program 32 were performed on three samples from the fuel rod NBD107 belonging to assembly BT03. The samples are identified as NBD107-MM, NBD107-GG, and NBD107-Q.…”

“…The experimental configuration and initial results for these tests have been reported elsewhere [6,7]. The two fuels are well-characterized [8,9] occurred this fiscal year.…”

Strategies for Application of Isotopic Uncertainties in Burnup Credit

“…Most notably, the models for the three Calvert Cliffs assembly BT03 samples were revised to include 12 burnable-poison shim rods and four non-fuel steel rods present in the assembly. The presence of these non-fuel rods was not documented in the Approved Testing Material (ATM-106) report 21 for these samples (the assemblies are incorrectly described as standard Combustion Engineering (CE) 14 × 14 assemblies containing 176 fuel rods) and thus they were not included in the original models. Information on the non-fuel rods and the updated assembly models was obtained from Ref.…”
