Sentences with phrase «in uranium dioxide»

In uranium dioxide, the oxygen atoms - key corrosion creators - do not diffuse randomly through the material.

The potassium - atom mouth of an organic molecule grabs one of the oxygen atoms (red) in uranium dioxide.

Not exact matches

The reactor uses uranium dioxide fuel particles that are also coated with graphite so they will not crack and release fission products even in extreme heat.

In 2010, Duke University researcher Robert Jackson found that, in theory, carbon dioxide leaking from underground storage sites — including in central Illinois — could contaminate drinking - water aquifers with pollutants such as uranium under the wrong conditionIn 2010, Duke University researcher Robert Jackson found that, in theory, carbon dioxide leaking from underground storage sites — including in central Illinois — could contaminate drinking - water aquifers with pollutants such as uranium under the wrong conditionin theory, carbon dioxide leaking from underground storage sites — including in central Illinois — could contaminate drinking - water aquifers with pollutants such as uranium under the wrong conditionin central Illinois — could contaminate drinking - water aquifers with pollutants such as uranium under the wrong conditions.

Radioactive uranium in the form of UO (2)(2 +) was trapped directly by the silicon dioxide support.

The fuel rods in most cases consist of uranium dioxide pellets encased in zirconium alloy tubes or cladding.

The gas - phase results are consistent with the spontaneous hydrolysis of PaO2 + in aqueous solution, this in contrast to heavier actinide dioxides of uranium, neptunium, and plutonium; the heavier actinide dioxides form stable hydrates in both solution and gas phase.

At left (a) is the uranium rod (in red) with a mixture of uranium dioxide and uranium hydride growing on the surface (yellow and orange).

Like older models, they will use uranium fission to heat water and drive a turbine, but these reactors will be smaller, simpler to build, and each will add more than 1100 megawatts of capacity to the region's power grid when they come online in 2016 or 2017 — without emitting carbon dioxide.

In addition, a relatively small amount of uranium can produce a relatively large amount of energy, helping the overall energy cycle of an online nuclear plant to release no more carbon dioxide per kilowatt - hour than solar power, which must account for the manufacturing of photovoltaic cells.
