Economics of nuclear fuel cycles : option valuation and neutronics simulation of mixed oxide fuels
… For Uranium Oxide (UOX) and Mixed Oxide (MOX) fuels, a traditional way to achieve this is to evaluate both fuels on the deterministic premise that the fuel will be sent to geologic disposal once spent. This methodology often leads to higher costs for cycles using MOX fuel. Geologic …

Management of the UK plutonium stockpile using thorium fuelled Light Water Reactors
… to centre around the use of Mixed OXide (MOX) fuelled Light Water Reactors (LWRs). Typically, MOX fuel involves the use of uranium (U) as a fertile carrier matrix for fissile Pu. However, the effect of aging and isotopic decay within the UK Pu stockpile impacts the feasibility of this …

Inkjet Printed Graphene-Based Smart Gas Sensors
… for gas sensing is dominated by metal oxide (MOx) based sensors due to their balance of performance and cost as well as the opportunity for simple device integration, potential for miniaturisation and incorporation into multi-analyte detection systems. However, MOx sensors have significant …

Feasibility Study of Minor Actinide Transmutation In Light-Water Reactors With Various Am/Cm Separation Efficiencies
… MA stream can be reprocessed and fabricated with MOX fuel and recycled in a reactor. Through transmutation, reductions in the radiotoxicity and decay heat of UNF can be achieved, which reduces the length of time that UNF must be sequestered from the environment. Because of the greater fission to …

Metal oxide supported iron-nickel nano-alloys in the reverse water-gas shift reaction
… their known hydrogenation activity. Metal oxide (MOx) catalysts, such as ceria, have also been studied for the RWGS due to their high oxygen storage capacity and reducibility at high temperatures. In recent work from the group of Fischer at the University of Cape Town, supported Fe-Ni …

Survival of Listeria monocytogenes in Fruit Juices During Refrigerated and Temperature-Abusive Storage
… Yeast Extract (TSAYE) and Modified Oxford Agar (MOX), followed by incubation at 32°C for 48 hours. When L. monocytogenes was no longer detected by direct plating, samples were enriched for L. monocytogenes using Listeria Enrichment Broth (LEB), followed by isolation on MOX. L. monocytogenes …

Fertile free fuels for plutonium and minor actinides burning in LWRs
… and they are all superior to the mixed UO2-PuO2 (MOX) fuel. From this point of view, there is no good reason to favor one inert matrix over another. The burning rates in terms of kg/(GWe-Year) of different inert matrix fuels are quite stable with regard to changing the moderation level (or H/HM …

Methane distribution and oxidation across aquatic interfaces
… at larger spatial scales. Methane oxidation (MOX) rates are commonly correlated with methane concentrations. This was shown in previous research studies and was substantiated by the present thesis. In detail, the highest MOX rates in the Arctic water bodies were detected in methane-rich …

Identifikation von Lysophosphatidsäure als Thrombozyten-aktivierende Substanz milde oxidierter Lipoproteine
… Aktivität von etwa ein nmol Palmitoyl-LPA/mg mox-LDL-Protein. Dies ist eine Menge, die bei den bislang beschriebenen Zellsystemen nachweislich Effekte hervorruft. Hier wurde dies für Thrombozyten aufgezeigt: Die in mox-LDL enthaltene LPA ruft dosisabhängig Gestaltwandel oder Aggregation in …

A clinical and molecular analysis of Clostridium difficile strains isolated from Groote Schuur Hospital
… to metronidazole (MET), vancomycin (VAN), moxifloxacin (MOX) and erythromycin (ERY) were determined by the Etest method. All were sensitive to MET and VAN; however, four ribotype 017 strains displayed reduced susceptibility to MET. With regard to MOX, reduced susceptibly and full resistance …

Coupling of system thermal-hydraulics and Monte-Carlo method for a consistent thermal-hydraulics-reactor physics feedback
… code coupling is demonstrated for the UO2 and MOX single assemblies based on the OECD-NEA/NRC PWR MOX-UO2 Core Transient Benchmark [1]. Comparisons of calculation results using the coupled code with those from the individual codes in stand-alone mode, also with deterministic methods, …

Analyzing the proliferation resistance of advanced nuclear fuel cycles : in search of an assessment methodology for use in fuel cycle simulations
… Non-Fertile and Uranium (CONFU), Mixed-Oxide (MOX), and Advanced Burner Reactor (ABR) fuel cycles. The metrics are roughly categorized in three groups: material characteristics, material handling characteristics, and "inherent" facility characteristics. Each metric is associated with its own …

Determination of economic shelf life of spent nuclear fuel
… nuclear fuel cycle services. BWR and PWR-UO₂/MOX spent fuel assemblies are modeled at 5 different burnups. The recycle modes that are examined are uranium recycle with and without fission product sales and uranium and plutonium recycle with and without fission product sales. UO₂ and MOX spent …

Evaluation of multilayer silicon carbide composite cladding under loss of coolant accident conditions
… low plenum pressure, thorium-based mixed oxides (MOX) are a promising fuel for SiC cladding because they have higher thermal conductivity and lower fission gas release (FGR). Previous efforts at MIT have modified the FRAPCON code to include thorium MOX fuel. In this work, the fission gas release …
