-
The UF6 is first vapourised in autoclaves with steam, then the uranyl fluoride is reacted with hydrogen at 700ºC to yield an HF byproduct for sale and U3O8 powder which is packed into 10-tonne containers for storage.
Uranium enrichment 2009
-
The approved nuclear fuel conversion procedure involved the dissolution of uranium oxide (U3O8) powder in a dissolution tank, then its transfer as pure uranyl nitrate solution to a buffer column for mixing, followed by transfer to a precipitation tank.
-
After initial refining, which may involve the production of uranyl nitrate, uranium trioxide is reduced in a kiln by hydrogen to uranium dioxide.
Uranium enrichment 2009
-
UF6 is hygroscopic (i.e., moisture-retaining) and, in contact with water (H2O), will decompose immediately to uranyl fluoride (UO2F2).
Uranium hexafluoride 2007
-
However, UF6 combines with water to form the soluble reaction products uranyl fluoride (UO2F2) and hydrogen fluoride (HF).
