    Feasibility Assessment of Adopting the ADDER Computer Code for the MIT Research Reactor Fuel Management by Garanzini, Maurane

    Published 2024
    “…The parameters selected for comparison include control blades height, cumulative fission density, integral neutron flux and nuclide inventory (for selected actinides and neutron poisons). The study showed satisfactory agreement between ADDER and MCODE results, with control blades worth differences within the 200 pcm range that corresponds to ± 100 pcm critical search tolerance, and U-235 mass differences remaining below 0.5 g per fuel element at end of cycle. …”

    Plutonium Migration during the Leaching of Cemented Radioactive Waste Sludges by Kathleen A. Law, Stephen Parry, Nicholas D. Bryan, Sarah L. Heath, Steven M. Heald, Darrell Knight, Luke O’Brien, Adam J. Fuller, William R. Bower, Gareth T. W. Law, Francis R. Livens

    Published 2019-01-01
    “…The sludges mainly comprise Mg hydroxide and carbonate phases, contaminated with fission products and actinides, including Pu. Cementation and deep geological disposal is one option for the long-term management of this material, but there is a need to understand how Pu may be leached from the waste, if it is exposed to groundwater. …”

    Research of Relationship Between Fuel Reliability and Iodine Isotope Activity Ratio 131I/133I in PWR Primary Coolant by FU Pengtao;LU Shengbo;LIANG Shan;YANG Xiaohuan;XU Jiehao;ZHOU Wenzhong;HAN Song

    Published 2022-01-01
    “…The statistical results of these operation data show that the higher volume activities of radio-iodine in the primary loops may result from the dissemination of actinides due to secondary hydriding from the previous cycles and the 131I/133I can be used to well identify the fuel reliability in comparison of the radio-iodine activities. …”
