Reactor physics calculations on MOX fuel in Boiling Water Reactors

CB&I AREVA MOX Services, LLC is designing and constructing the Mixed Oxide (MOX) Fuel Fabrication Facility at the U.S. Department of Energy's Savannah River Site. The first-of-a-kind $4.8 billion facility is a key component of the National Nuclear Security Administration's program to dispose of surplus weapons-grade plutonium. Distinct from traditional nuclear fuel with enriched uranium, mixed oxide (MOX) fuel pellets are based on the mix of nuclear fuel cycle derivatives, such as oxide of plutonium bred in commercial reactors, and oxide of depleted uranium which comes from defluorination of depleted uranium hexafluoride (UF6), the so-called secondary tailings of uranium enrichment facilities. MOX fuel has a lower melting temperature and a lower thermal conduc- tivity than UOZ fuel, and bumup and/or deviation from stoichiometry reduce the thermal conduc- tivity of both UO2 and MOX fuels significantly. The never-completed and now-shuttered Mixed Oxide Fuel Fabrication Facility was born from the PMDA; the Savannah River Site plant was supposed to turn the U.S. cache into fuel for nuclear reactors. LEU fuel is a homogeneous mixture of U-238 dioxide and U-235 dioxide, whereas MOX fuel is more heterogeneous, with very small plutonium-rich particles in a matrix of depleted uranium oxide.

This paper compares the two approaches from the view of fuel cost. Two features are involved. (1) The cost of electricity (COE) is investigated based on the simulation The mixed oxide fuel proposed by Shaw AREVA MOX Services (formerly Duke COGEMA Stone & Webster (DCS)) is a blend of plutonium dioxide and depleted uranium dioxide that will be used as fuel in commercial nuclear power plants. Depleted uranium is a byproduct of the uranium enrichment process. The ORANO MELOX recycling plant, located on the Marcoule site in the Gard, manufactures MOX fuels for nuclear power generation plants in various countries.

As both uranium and plutonium are present in oxidised form, the new fuel is referred to as 'mixed oxides' or MOX. Today, some 19 nuclear reactors in France are regularly loaded with MOX fuel. the introduction of MOX fuel causes the number of glass units per GWd to double owing to the increase in the heat generation rate. An extended cooling period of the spent fuel prior to reprocessing eﬀectively reduces the heat generation rate for UO 2 fuel, while a separation of minor actinides (Np, Am, and Cm) The Orano Melox recycling plant, located in Marcoule, Gard, produces Mox fuel assemblies made from a blend of uranium oxide and plutonium developed from spent fuel.

It runs similarly to Thorium fuel in a small reactor, but it lasts longer, however, in a large reactor it runs more akin to standard Uranium fuel. MOX is a recycled fuel that recovers the plutonium contained in used fuel. Far from being limited to France, it is currently the focus of a number of important projects around the world.

Abstract - Kärnfysik

MOX (Mixed Oxide) fuel is a late-stage nuclear fuel, it is a mixture of both Uranium and Plutonium isotopes. It is quite expensive to produce, as it requires 2 types of fissile material instead of the usual 1. It runs similarly to Thorium fuel in a small reactor, but it lasts longer, however, in a large reactor it runs more akin to standard Uranium fuel.

Fuel tanks come in a variety of sizes, with compact cars generally having much smaller capacity tanks than large cars or tr If you're wondering where to buy kerosene fuel, you're probably heading out on a camping trip, using kerosene as an alternative to natural gas in your heater or setting up your emergency lamps for bad weather. Kerosene fuel is versatile and For those who are living on a budget, finding the best deals on fuel oil is a priority.
