uranium
A heavy, radioactive chemical element that is mainly used as fuel in nuclear power plants and for nuclear weapons.
Für den Betrieb des Atomreaktors wird angereichertes Uran benötigt.
Enriched uranium is needed to operate the nuclear reactor.
As with many substances and materials, 'Uran' (uranium) is used without an article when talking about the substance in general. The article 'das' (the) is used when a specific amount or type is meant.
Uran ist ein radioaktives Element.
Uranium is a radioactive element.
In the context of nuclear energy, the combinations 'angereichertes Uran' (enriched uranium) and 'abgereichertes Uran' (depleted uranium) are very common. Typical verbs are 'Uran anreichern' (to enrich uranium) or 'Uran abbauen' (to mine uranium).
Es ist ein komplexer Prozess, Uran anzureichern.
Enriching uranium is a complex process.
'Uran' (uranium) is a technical term from chemistry, physics, and engineering. You find the word mainly in scientific, technical, or political texts.
In der Konferenz wurde über die sichere Lagerung von Uran diskutiert.
At the conference, the safe storage of uranium was discussed.
plutonium
'das Uran' and 'das Plutonium' are both radioactive chemical elements and are connected with nuclear energy and nuclear weapons. For this reason, learners may confuse them. 'Uran' is a naturally occurring heavy element and is mentioned especially as fuel in nuclear power plants. 'Plutonium' is also a heavy, toxic radioactive element and is especially known from the context of nuclear weapons and special reactors. In normal texts, you should not swap the words, because they refer to different substances.
Im Unterricht hat die Lehrerin erklärt, dass Uran in manchen Kernkraftwerken als Brennstoff dient.
In class, the teacher explained that uranium is used as fuel in some nuclear power plants.
Plutonium ist sehr giftig und darf nur unter strengem Schutz gelagert werden.
Plutonium is very toxic and may only be stored under strict protection.
