Sentences with phrase «uranium fuelled processes»

Not exact matches

Indian Point's nuclear power is neither clean nor green, and the process needed to create fuel from uranium for its reactors is energy - intensive and creates greenhouse gases such as carbon dioxide.

The article, published recently in Open Chemistry may lead to the development of a process to remove uranium from wastewater at the front - end of the nuclear fuel cycle, or even extracting natural uranium from sea water.

They say enriching uranium at a processing plant poses less risk than handling spent nuclear fuel, which is highly radioactive, at a reactor.

Because the world's uranium supply is finite and the continued growth in the numbers of thermal reactors could exhaust the available low - cost uranium reserves in a few decades, it makes little sense to discard this spent fuel or the «tailings» left over from the enrichment process.

In addition, only about one tenth of the mined uranium ore is converted into fuel in the enrichment process (during which the concentration of uranium 235 is increased considerably), so less than a hundredth of the ore's total energy content is used to generate power in today's plants.

Standard reactor design helps fuel a boom After testing their first nuclear weapon in 1960, the French turned their infrastructure for enriching and processing uranium toward energy.

If the approach is successful, it could be considered for other sites where uranium was processed for nuclear arsenals or power plant fuel.

Essentially all nuclear fuel recycling is performed using a process known as PUREX (plutonium uranium extraction), which was initially developed for extracting pure plutonium for nuclear weapons.

Instead, the price rise seems to reflect the increasing importance of the secondary, or pre-mined and processed market, as sources of uranium for use in the reactor fuel market.

Other «secondary sources» of uranium include uranium previously processed to make nuclear weapons cores or reactor fuel, but never consumed.

Further processing and enriching of the uranium produces a material to fuel nuclear power plants.

Through a multi-step process in Russia, the bomb - grade uranium material was converted into a different chemical form and then diluted into low enriched uranium suitable for use in fabricating commercial nuclear power reactor fuel.

In ENUSA we manufacture nuclear fuel in our Juzbado facility (Salamanca), where the activities focus on procurement of the uranium and components required for the process and on the engineering and manufacturing of fuel assemblies for Spanish and European nuclear power plants, using the most innovative technologies and latest market advances.

Find out how the uranium fuel that powers the world's nuclear reactors is mined and processed in several important steps that make up the nuclear fuel cycle.

• Ceramic process in which uranium oxide powder is used to manufacture pellets; these pellets are inserted into zirconium alloy tubes which, once they are loaded, pressurized and sealed, are called fuel rods.

Which is a good job, given the shortage of high - grade uranium ore, the huge unmanageable risks associated with nuclear plants and nuclear proliferation, the large amounts of embedded carbon in uranium refining and processing (and other GHG emissions from the nuclear industry), and the insanity of developing a huge strategic fuel dependence on countries such as Russia.

But it will take nothing less than for the industry to shift from its conventional reactor designs and from the uranium 235 fuel process on which it began to settle in the 1960s, according to Sorensen.

Valid SCIENCE will readily allow Gas (and Coal) processes as fuel for such purposes, and I have been warning of this Uranium outcome for years, NOW however is when «it is happening».

Plutonium in the spent fuel is easily separated from other waste through chemical processing and, like the uranium, can be used to make a nuclear bomb.

-- The Nuclear Regulatory Commission shall establish standards for protection against radiation (including occupational exposures) resulting from activities at facilities that use an advanced fuel recycling process, including facilities to fabricate fuel enriched with actinide elements other than uranium.

-- The Administrator of the Environmental Protection Agency shall establish generally applicable environmental standards for the protection of the public and the general environment from radioactive material released from facilities that use an advanced fuel recycling process, including facilities to fabricate fuel enriched with actinide elements other than uranium.

While nuclear energy is regarded as the lesser of the two evils when compared at an emission level to the burning of fossil - fuels, it may trump on the containment of the heat process, which burns in a contained nuclear reactor through an in - ward heat - chemical reaction called fission, but nuclear energy production is a chain from uranium mining to the toxic waste disposal and therefore as an entire process is an equally high risk environmental option.

The used fuel pellets from current reactors (after processing to convert the uranium oxide to uranium tetrafluoride) could just be dumped in the molten salt.

Standard reactor design helps fuel a boom After testing their first nuclear weapon in 1960, the French turned their infrastructure for enriching and processing uranium toward energy.

To make fuels for nuclear power plants, we have to go through the whole process of uranium mining, transporting, and disposing.
