LWR spent fuel radiochemical measurements and comparison with ORIGEN2 predictions

The Materials Characterization Center (MCC) at Pacific Northwest Laboratory (PNL) is responsible for providing characterized spent fuel, designated Approved Testing Materials (ATMs), for subsequent use in the investigation of nuclear waste disposal forms by the US Department of Energy geologic repository project. The ATMs are selected to assure that test material is available that has a representative range of characteristics important to spent fuel behavior in a geologic repository. Burnup and fission gas release were the primary criteria for selecting the ATMs. The five spent fuel ATMs (ATM-101, -103, -104, -105, and -106) currently being characterized by the MCC have rod average burnups ranging from 28 MWd/kgM to 43 MWd/kgM, fission gas releases ranging from 0.2% to 11.2%, and are from both boiling water reactors and pressurized water reactors. 8 refs., 2 tabs.
