English term or phrase: yellow cake
Definition from European Nuclear Society:
Yellow cake is the final product of the milling of uranium ore. It contains about 80 % of uranium oxide and is usually represented by the formula U3O8. The yellow cake produced by most modern mills is actually brown or black, not yellow; the name comes from the colour and texture of the concentrates produced by early mining operations due to impurities from ammonium diuranate (NH4)2U2O7.

Example sentence(s):
  • The solvents are removed by evaporating in a vacuum and ammonium diuranate, (NH4)2U2O7, is precipitated by adding ammonia to neutralize the solution. The diuranate is then heated to yield a purified, solid U3O8, known as yellow cake. Kennesaw State University
  • On site, close to the mines, the uranium is concentrated and transformed into a yellow powder, commonly called yellow cake, which contains 75% of uranium. It is in this form that the uranium is marketed.
  • The first stage of this process is to dissolve the yellow cake in nitric acid; solvent extraction using tributyl phosphate in a hydrocarbon solution extracts the uranium from the various impurities and then the extract is washed with dilute nitric acid to produce uranyl nitrate in a very pure form.

Definition from ETC:
Term die wordt gebruikt voor verijkt uranium. Nadat uranium is gedolven, wordt het verkocht als yellowcake. Het gedolven uranium wordt verwerkt tot een fijnkorrelige stof die geel van kleur is.

Example sentence(s):
  • `Yellowcake` (ammonium diuranaat) is een natuurlijk uraniumerts. Het bevat 70 tot 80 gewichtsprocent Uraniumoxide (U3O8). - Teacher's paradise  
  • Voor verdere verwerking wordt dit verwerkt tot `Yellowcake`(ammoniumdiuranaat), dit bevat 70 tot 80 gewichtsprocent uraniumoxide (U3O8). - Wikipedia  
  • Het wordt ter plaatse geconcentreerd, waarbij de zogenaamde yellow cake ontstaat die voor tachtig procent uit uraniumoxide bestaat. - Chemische Feitelijkheden  

Vaak wordt er naar yellow cake verwezen als ammoniumdiuranaat, maar dit houdt niet stand als de stof voor minstens 70% uit uraniumoxide bestaat. Het letterlijk vertaalde "gele koek" is niet echt gangbaar. Vandaar dat onvertaald mij het meest geschikt lijkt.
Oveirgens wordt het ongeveer net zo vaak als `yellow cake` (met spatie) gespeld.
