Heavy Water in a sentence

Semi-heavy water could, in theory, be created via a chemical method, but it would rapidly transform into a dynamic mixture of 25% light water, 25% heavy water, and 50% semi-heavy water.

It used the Girdler sulfide process to produce heavy water, and required 340,000 tonnes of feed water to produce one tonne of heavy water.

Deuterium can replace the normal hydrogen in water molecules to form heavy water (D 2 O), which is about 10.6% denser than normal water (so that ice made from it sinks in ordinary water).

Light water also acts as a moderator, but because light water absorbs more neutrons than heavy water, reactors using light water for a reactor moderator must use enriched uranium rather than natural uranium, otherwise criticality is impossible.

IR-40 also known as Arak Nuclear Plant is an Iranian 40 megawatt heavy water reactor under construction near Arak, adjacent to the 1990s era Arak Heavy Water Production Plant.

Heavy water that has been used as a coolant in nuclear power plants contains substantially more tritium as a result of neutron bombardment of the deuterium in the heavy water ( tritium is a health risk when ingested in large quantities).

Improved efficiency in the use and recycling of heavy water plus the over-production at Bruce left Canada with enough heavy water for its anticipated future needs.

In wartime Germany, failure to appreciate the qualities of very pure graphite led to reactor designs dependent on heavy water, which in turn was denied the Germans by Allied attacks in Norway, where heavy water was produced.

Prokaryotic organisms, however, can survive and grow in pure heavy water, though they develop slowly. citation Despite this toxicity, consumption of heavy water under normal circumstances does not pose a health threat to humans.

The Bruce Heavy Water Plant in Ontario was the world's largest heavy water production plant with a capacity of 700 tonnes per year.

The heavy water production facility located at Arroyito (Neuquén Province) is the world's largest heavy water production facility.

Once HDO becomes a significant fraction of the water, heavy water becomes more prevalent as water molecules trade hydrogen atoms very frequently.

The weight of a heavy water molecule, however, is not substantially different from that of a normal water molecule, because about 89% of the molecular weight of water comes from the single oxygen atom rather than the two hydrogen atoms.

There are also the issues of deforestation, heavy water usage and soil erosion from water run off.

It turns out that snow contains around 40% less heavy water than normal water.

A molecule of heavy water has two deuterium atoms in place of the two protium atoms of ordinary "light" water.

Commercial-grade heavy water is slightly radioactive due to the presence of minute traces of natural tritium, but the same is true of ordinary water.

Heavy water is slightly toxic in eukaryotic animals, with 25% substitution of the body water causing cell division problems and sterility, and 50% substitution causing death by cytotoxic syndrome (bone marrow failure and gastrointestinal lining failure).

In theory, deuterium for heavy water could be created in a nuclear reactor, but separation from ordinary water is the cheapest bulk production process.

It seems that the electrical conductivity of heavy water with lithium is considerably less than that of light water with lithium.
