Triuranium octoxide (U 3 O 8) [2] is a compound of uranium. It is present as an olive green to black, odorless solid. It is one of the more popular forms of yellowcake and is shipped between mills and refineries in this form.

2018年2月26日 · The production of uranium concentrate, also known as triuranium octoxide (U3O8), or more commonly as yellowcake, is the first step in the nuclear fuel production process. Uranium concentrate is then converted into uranium hexafluoride (UF6), enriched, fabricated into fuel pellets, and loaded into nuclear fuel assemblies.

Triuranium octoxide (left) and uranium dioxide (right) are the two most common uranium oxides. Calcined uranium yellowcake, as produced in many large mills, contains a distribution of uranium oxidation species in various forms ranging from most oxidized to least oxidized.

Before fuel fabrication, i.e., before conversion or enrichment, yellowcake is refined to obtain almost pure uranium in the form of triuranium octoxide (U 3 O 8).

2023年9月14日 · Over 900 million pounds of U3O8 (triuranium octoxide, one of the more popular forms of uranium yellowcake) have been produced since 1975 from the basin.

U.S. uranium mines produced 50,000 pounds of of triuranium octoxide (U 3 O 8), or uranium concentrate in 2023, a significant decrease from the 194,000 pounds produced in 2022 as no production occurred at White Mesa Mill in Utah. The production of uranium concentrate is the first step in the nuclear fuel production process, preceding the ...

2022年2月22日 · Triuranium octoxide (U 3 O 8) is one of the main compounds in the nuclear fuel cycle. As such, identifying its processing parameters that control the oxygen isotopic composition could be developed as a new signature for nuclear forensic investigation.

Modern yellowcake typically contains 70% to 90% triuranium octoxide (U 3 O 8) by weight. Other oxides such as uranium dioxide (UO 2) and uranium trioxide (UO 3) exist. [4] Yellowcake is produced by all countries in which uranium ore is mined. [1]
