The heavy water is held in an acrylic sphere, and is surrounded by a network of nearly 10, 000 photomultiplier tubes.
ECONOMIST: The news that neutrinos have mass is both good and bad
However, it does continue to pursue uranium enrichment and the construction of a heavy water reactor, both of which have military potential.
Iran also began building an actual weapons reactor, a 40 MW heavy water reactor at Arak, that would take natural uranium, and produce plutonium.

Never mind that they showed the difference between heavy water (with deuterium atoms) and ordinary water (with hydrogen atoms) in a way that no image had done before.
ECONOMIST: Paul Lauterbur, father of MRI, died on March 27th, aged 77
Cynics are paraphrasing Marie Antoinette: Let them drink heavy water.
Moreover, between the Russian-built, soon-to-be-opened nuclear reactor in Bushehr and the illicit heavy water reactor in Arak, Iran will have the capacity to build plutonium-based bombs within two years.
It also allowed IAEA inspectors to enter its heavy water plutonium production facility in Arak - a largely insignificant concession since the plant won't be operational for two years.
It consists of 1, 000 tonnes of heavy water (the sort that has deuterium, a heavy form of hydrogen, in its molecules, instead of the normal, light form of the element).
ECONOMIST: The news that neutrinos have mass is both good and bad
Heavy water is heavy because the hydrogen in it weighs twice as much as ordinary hydrogen (it has a proton and a neutron in its nucleus, instead of just a proton).
Shale-gas producers also face opposition from greens, who object to the industry's heavy water usage and a small risk that fracking could lead to contamination of aquifers and even to earthquakes.
ECONOMIST: The ��golden age of gas�� could be cleaner than greens think
At Commons question time on 31 January 2011, Dr Fox said Tehran was continuing to pursue uranium enrichment as well as the construction of a heavy water reactor, both of which had "military potential".
The traces of highly-enriched (not just fuel-grade) uranium, their deception, their heavy water plant and other indicators brand their program as one designed to develop nuclear weapons even in the absence of considering their rhetoric about destroying Israel and ending the world.

Iran is also building a heavy-water reactor that could produce plutonium, another bomb ingredient.
ECONOMIST: The Europeans' soft approach to Iran seems to have failed
Iran, by comparison, is producing near-weapons-grade uranium, but it also has a heavy-water reactor being developed that could produce weapons-usable plutonium.
In both cases, he used the heavy-water method to monitor cell division.
The enrichment plants at Natanz, Qom and perhaps elsewhere give Iran an early route to HEU. A planned heavy-water reactor at Arak will produce large quantities of plutonium as a by-product, but will not be completed for some years.
Right now, at our current low levels of carbon dioxide, plants are paying a heavy price in water usage.

But a dozen studies since 2005 have found the presence of heavy metals in water to be within legal limits.
Rice growing, in particular, is a heavy consumer of water: it takes some 5, 000 liters of water to produce 1 kg of rice.
Covering "vast areas" in concrete could also mean rivers bursting their banks after heavy rainfall because water will run off the land more quickly he said.
In addition to radioactive contaminants, the material also removes salt and heavy metals from water making it ideal for use in treating water after natural disasters.

Now instead of traveling long distances carrying heavy vats of water, or migrating to the cities to make a living, the villagers can stay put and begin to enjoy their surroundings more.
Other costs are the impact on the lives of women and girls who spend several hours every day carrying heavy loads of water thus reducing the time women have available for growing food, working to earn an income or take care of children, and preventing girls from attending school.
