Varian low/single photon energy linear accelerator machines manufactured in the 1970's through the early 1990's often contain depleted uranium shielding (also referred to as counterweights), a radioactive material that must be handled appropriately during the removal and disposal of this equipment. NRC regulations require such material to be …

This research used machine learning methods to study the corrosion of uranium and uranium alloys in air and established a corrosion weight gain prediction model. Eleven classic machine learning algorithms for regression were compared and a ten-fold cross validation method was used to choose the highest accuracy algorithm, which was the …
The principle of the countercurrent gas centrifuge is illustrated in Figure 4-1, "Idealized Schematic of Gas Centrifuge.". The renewed interest in the GC process is driven by the …
Planet is a general-purpose, vertical-lift assembly machine comprised of an upper stationary platform and a lower movable platen. The Planet assembly machine was …
Depleted uranium is a by-product of the production of enriched uranium for use in nuclear reactors. Although very low in radioactivity, depleted uranium must be physically protected and may be subjected to international safeguards. Commercially, depleted uranium is used in medicine, space, aviation and petroleum exploration.
The researchers made the finding using cutting-edge technology and equipment to examine depths up to 3,000 meters or almost 10,000 feet. That is six times deeper than most of China's uranium mines.
Uranium-235, an isotope that makes up less than 1 percent of all-natural uranium, provides the fuel for nuclear reactors and nuclear bombs, while uranium-238, an isotope that makes up 99 percent ...
Iran has escalated its uranium enrichment further with the use of advanced machines at its underground Fordow plant in a setup that can more easily change between enrichment levels, the U.N ...
The calculated melting line of uranium at pressures up to 80 GPa and the temperature of the α-γ transition at 3 GPa agree well with the experimental phase diagram of uranium. View Show abstract
In this work, a machine-learning interatomic potential based on the moment tensor potential framework was developed for uranium. To assemble the training dataset of uranium, an active learning method was adopted. Energy and force of the data sets were calculated using the DFT+U method to account for the strongly related 5f electrons of uranium ...
The company's original AC-100 machine was developed over the years with support from DOE and later refined by Centrus to the current AC-100M machine under contract with Oak Ridge National Laboratory. The machines will be used to enrich uranium hexafluoride gas to produce up to 600 kilograms of HALEU by June 2022 to support advanced reactor ...
1. Introduction. Uranium dioxide (UO 2) is an extremely important and commonly used nuclear fuel.As experiments with UO 2 can be quite challenging due to its hazardous and radioactive nature, computational models present a desirable avenue for better understanding the properties of uranium dioxide. One powerful modeling tool for the …
CONVENTIONAL MINING AND MILLING OF URANIUM ORE Introduction. Production of uranium concentrates, in the form of U3O8, or "Yellowcake" as it is commonly referred to in the industry, from ore which is mined by open pit or underground methods and processed to recover uranium, employs technology and methods common to the mining industry.
That's where uranium comes in. Nuclear energy is a truly clean form of energy, and uranium is an essential component of the nuclear fuel needed to power nuclear reactors. In this special presentation, we're providing a quick analysis of seven uranium stocks likely to benefit from rising uranium prices in 2024 and beyond.
