The agreement calls for the Energy Department's Isotope Program to purchase the heavy water from a subsidiary of the Atomic Energy Organization of Iran, for about $8.6 million, officials said.

This assessment is based on the presence of a very specific signature: steam is venting from the reactor's cooling system" he said.Its expansion appears to be part of an effort to increase the production of weaponsgrade plutonium allowing Pakistan to build a larger number of miniaturized plutoniumbased nuclear weapons that can complement its existing highly enriched uranium nuclear weapons" they wrote.They said that originally the site consisted of a heavy water production plant and an estimated 50 megawattthermal (MWth) heavy water reactor both of which became operational in the 1990s.

It has refused to change the Arak heavy water reactor into a light water reactor, on the basis that heavy water is needed to produce radioisotopes for the treatment of patients while it already manufactures light water in Bushehr to help generate electricity.

The picture shows a heavy water ice cube sinking in normal water.

The leakage was not even kilos of heavy water. There is nothing to worry about,'' the official said.

On the night of February 28, 1943, the party started out for the heavy water works.

This is countrys first 700 MW pressurized heavy water reactor (PHWR) plant being developed by NPCIL.

Conversely, hydrogen bonds--relatively weak bonds connecting the oxygen in one molecule with the hydrogen or the deuterium in another--are four percent longer in heavy water than in light.

A gas leak killed two people yesterday at a heavy water plant run by Pakistan's atomic energy agency in central Punjab province.

The recycling solution is initially being applied to Candu pressurised heavy water reactors.
